      Turnarounds or maintenance on the horizon? Tell us in time about your plans

      Now that there is a light at the end of the COVID-19 tunnel, companies are preparing for turnarounds and repairs that have been postponed due to COVID.

      We notice that customers are now busy planning for 2021 and 2022. This confirms the expectation that postponing jobs and projects and projects is leading to an increased demand for maintenance services in 2021 and later.

      Maintenance Partners strives to offer its customers an optimal service. The sooner we are informed about your maintenance plans, the better we can prepare ourselves together with you.

      Do you have turnarounds or maintenance on the horizon? Let us know by filling in our questionnaire. This way you can be sure that your maintenance is executed as planned.

       

      Troubleshooting of Atlas Copco compressor at air separation plant

      Maintenance Partners was contacted by a customer that was not able to restart its Atlas Copco GT 078 L3K1 integrally geared compressor after a planned shutdown.

      The machine is critical to the production process of the air separation plant and the customer needed to restart the compressor as quickly as possible. Despite Covid-19 related restrictions, Maintenance Partners was able to dispatch a service engineer immediately to analyze and solve the problem.

       

      Situation

      After a planned shutdown of two days, the customer was not able to start-up the unit again as it was tripping on high vibration on the 2nd and 3rd stage bearings. Following this, the plant’s rotating equipment engineers decided to make a second attempt to start the machine with raised vibration trip limits, which was successful. After loading the compressor, the vibration level could be stabilized just around the initial trip limits. But it was clear, that immediate action was required to investigate and rectify the cause for the measured high vibrations.

      Despite the Covid-19 restrictions, Maintenance Partners was able to mobilize a service engineer to the client site immediately after being contacted.

      As there were some requirements to meet by the customer, a stop of production was the least desirable outcome. The contingency plans made by the customer did indicate that we would only be able to get a two-day maintenance window in two weeks.

      Preparation / Investigation

      From this point on, several things had to be done in parallel to be ready for each possible outcome:

      • Troubleshooting and analysis of the problems
      • Checking of spare parts availability and condition of them
      • Inspection of special tools
      • Checking of required tooling and lifting equipment
      • Checking the availability of consumables and sourcing of them
      • Sourcing of local manpower for a potential overhaul
      • Detailed planning of the jobs with different scopes depending on the findings
      • Writing of detailed work instructions
      • Exploring different scenarios including repairs and high-speed balancing in case needed

       

      The root cause analysis which ran in parallel, together with the customer’s competence center and the specialist from the vibration monitoring system revealed following findings:

      • 2nd stage vibrations most probably due to unbalance
      • 3rd stage vibrations caused by restricted shaft movements
      • No explanation could be found why both problems appeared at the same time after a two-day shutdown

      Based on the findings and the status of the preparation, the customer was confident to de-mobilize the Service Engineer of MP for one week which was needed to fulfill their production obligations and then re-mobilize to execute the planned intervention. In the meantime, all missing items identified were purchased and the last preparations were finalized.

       

      Execution

      Immediately, after arrival on site, work on the machine began. The detailed preparation allowed the customer to have all required permits issued, tools and lifting equipment ready and the crew briefed in depth about upcoming work. This allowed us to work very efficient with no waiting time or stops because of unexpected findings and problems.

      The stages were completely, disassembled, cleaned and inspected. Where needed, corrective actions were taken to rectify the problems.

      Findings

      The main findings were:

      • The 2nd stage impeller was not only affected by some deposits but also subjected to erosion damages which contributed to the impeller imbalance.
      • The 3rd stage bearing exceeded the designed bearing clearances by factors
      • 3rd stage carbon seals were blocked which cause deep grooves on the shaft

      Further, several dimensions like impeller line-up, axial clearances, etc. were found out of spec.

      Due to the time constrains and in order to stay within the given shutdown window, only the most severe problems could be addressed while other non-critical issues were postponed to the next planned major overhaul.

      Start-up

      After the two day intervention, the machine was successfully re-started on the third day with vibration levels way below the alarm level. This makes us confident, that the customer will be able to operate the compressor until the next planned major overhaul in April 2022.

      We are looking forward to plan and prepare together with the customer the up-coming overhaul of three integrally geared machines next year and the execution of it in 2022.

       

      Result for the customer

      Thanks to the quick intervention, the troubleshooting could be executed within the available 2-day maintenance window and effect on the customer’s production was reduced to a minimum.

      Moreover, the customer is able to continue to keep the compressor running until the scheduled major overhaul.

          Reingeniería extrema y reparación de la turbina de vapor monoetapa KKK CF4G

          Maintenance Partners fue contactado por un cliente después de la avería de una turbina de vapor monoetapa.

          Los daños en la turbina eran graves: las alojamientos de los rodamientos, el piñón y los dientes del engranaje principal estaban dañados.

          Para empeorar las cosas, la carcasa superior estaba agrietada. Varias empresas informaron al cliente que la turbina era una pérdida total y que la única solución era reemplazar toda la turbina.

          Maintenance Partners, sin embargo, nunca dice que no a un desafío. Nuestros expertos encontraron una solución y propusieron al cliente reparar la turbina. La reparación de la turbina resultó ser mucho más rápida y económica que la sustitución de la turbina por una nueva.

           

          Ingeniería inversa y reparación

          Después de que el cliente aceptó la propuesta de reparación, la turbina fue desmontada en el taller de MP y nuestros ingenieros comenzaron el proceso de ingeniería inversa. Como la turbina había estado funcionando durante más de 4 décadas, los planos no estaban disponibles. Las partes dañadas fueron escaneadas en 3D y se prepararon los planos de fabricación.

          El piñón y el engranaje principal no podían ser restaurados y las nuevas piezas se fabricaron utilizando los planos. Los cuatro rodamientos y los alojamientos de rodamientos también fueron renovados completamente. Una rueda de turbina de repuesto que el cliente tenía en stock fue montada en el eje con el piñón. El rotor ensamblado fue equilibrado a baja velocidad.

          Para restaurar la carcasa, se realizó un análisis de materiales para determinar la aleación del material existente. Se fabricó una nueva pieza que se ajustaba al material para que encajara en el hueco de la carcasa. La carcasa fue pre-mecanizada antes de unir la nueva pieza a la carcasa. Finalmente, la carcasa se mecanizó a las dimensiones originales.

          Cuando todas las partes fueron fabricadas, la turbina fue ensamblada y lista para su puesta en marcha in situ.

          Resultados para el cliente

          La turbina de vapor monoetapa se había considerado como una pérdida total, pero Maintenance Partners encontró una solución más rápida y económica para el cliente.

            “PRIAM”: Project of Artificial Intelligence for Maintenance

            Maintenance Partners is excited to be part of “PRIAM”: Project of Artificial Intelligence for Maintenance. AI technologies dedicated to predictive maintenance and performance optimization based on many data sources with the partners Performance for Assets, ICARE*, I-Pulses SPRL and Pôle MecaTech.

            Based on a consortium of 4 companies with high level of complementary expertises in industrial sectors (assets repair and reliability), AI and analytics, a new project has been launched to show through a proof of concept that the technical access and economical profits are available to any company. Indeed, based on the results shown by this POC, all the industrial actors and more specifically SME will have access to these tools to offer more services and to add value to their actual portfolio which could be extremely important in the actual context.

            Furthermore a more global solution could be offered to any other sector of activities which want to use these digital tools and to switch to a digital transition thanks to Artificial Intelligence and 4.0 Technologies.

             

             

            This project is more than an idea today as a first prototype of this solution has already been tested on the field with many different sensors and data bases with extremely good results. But now, thanks to this POC, many additional sensors and data from different natures will be downloaded simultaneously to maximise the use of this tool for any application.

            The goal is also to prove the efficiency of Data Analytics tools and the fact that any company could use this solution to start a digital switch or to add a new weapon to its AI and Digital tool.

            Of course, many updates will follow with some practical examples to show more in details and on the filed what is possible to do.

             

            More information

            For any request, if you want to test this solution in your company or even to know more about this specific project, don’t hesitate to contact us:

              Steam turbine Rotating Unbalance: Root Cause identified and solved within 5 days by MP’s experts!

              A customer operating a biomass fired powerplant contacted Maintenance Partners about a vibration alarm that was generated by the steam turbine control system.

              Initial Data Analysis

              The initial analysis of the data trends provided showed that the vibration was generated inside the steam turbine – possibly caused by friction.

              Any contacts between rotor and stator (even if initially small) create local heating spots by friction.

              These heating spots initiate a deformation of the shaft and as a consequence a residual unbalance, which further increases the heating.

               

              This is called the Newkirk phenomenon is auto-amplifying and eventually leads to the trip of a turbine. A detailed vibrational analysis can be used to identify this phenomenon.

              Detailed Vibration Analysis

              By studying the Nyquist diagrams, the vibrational specialists of Maintenance Partners were able to locate the origin of the problems and could validate the necessity to open the turbine.

               

              The inspection of the steam turbine confirmed that oil mist particles had entered the first labyrinth of the gland steam stuffing box. The oil mist particles had carbonized, creating contact points.

               

              Maintenance Partners installed an online vibrational monitoring device, connected to a remote connection. Specialists from MP Belgium and France then joined in efforts for remote diagnosis.

               

              A team of technicians then opened the turbine and clearly identified the problem.

              First analysis on Friday and turbine opened on Wednesday !

               

               

              After the inspection, the rotor was sent to Maintenance Partners’ Rotorshop for repair and balancing.

                  GEMEX belt tensioning system increases fan uptime

                  Maintenance Partners recently carried out a conversion of an electric motor platform at a chemical plant in the Netherlands.

                  The existing motor platform was replaced by an IEC 315H Gemex system. This type of Gemex is suitable for IEC 315 motors with a weight of +/- 1000KG and consists of 2 separate feet each with a mechanical/hydraulic cylinder, which are hydraulically coupled together.

                   

                   

                  Reduced Downtime 

                  This Gemex system supports an electric motor drives an exhaust fan. This extraction fan is essential for safety in the factory. For the customer it is important that the downtime of the extraction fan is reduced to a minimum.

                  Thanks to the Gemex system, belts  can be changed quickly and safely, without having to re-align the motor. In addition, the correct alignment and belt tension ensures a longer life of v-belts, pulleys and bearings.

                   

                  Assessment

                  Maintenance Partners can make a detailed assessment of all your belt driven applications without any obligation. An inventory is made of the unit in question with a report on the possibilities, costs and ROI. MP takes care of the complete conversion from engineering to installation.

                  Contact us

                  Would you like to know more about the alternative for your traditional belt tensioning system and how it can improve your safety, productivity and reliability? Contact us for more information or a pilot project to test the Gemex system at your facilities.

                    Sautter-Harle Ljungström generator from 1956 ready for the future after rewinding

                    Machines today are no longer built to last forever. Just think of a computer that lasts an average of four years and then needs to be replaced. It used to be different. For example, electric motors that were put into operation in the middle of the last century are nowadays still used daily in industrial processes, almost everywhere in the world. Over the years, however, expertise on these machines has gradually declined. A company that uses a twentieth-century turbo machine, i.e. an aging asset, becomes vulnerable when that machine needs maintenance. The original manufacturer no longer exists and very few companies can still provide the maintenance service.

                     

                    Hairpin coils

                    The Sautter-Harle Ljungström (or STAL radial flow) turbine-generator set in question dates from 1956 and can be called very compact and durable, but at least atypical. While in more recent steam turbines the steam usually moves axially, this turbo machine consists of a radial turbine that drives two 2310 Kva generators

                    In addition, the generator is equipped with a single-layer winding, which is still rare. With a normal winding, the coils are inserted through open slots, which are inserted from the inside. This type, which works with hairpin coils (or piercing windings), is very different. These are semi-closed slots. The coils are pushed through and have to be shaped completely by hand on the outside. A labour-intensive and very specific job, for which many companies no longer have the knowledge in house. For the same reason, this type of winding is no longer used in modern machines. The advantages of a smaller turn do not outweigh the cost of this expensive system.

                     

                    Mechanical & electrical expertise

                    The great added value that Maintenance Partners was able to offer this client was the possibility of tackling the machine as a whole. The great advantage of having everything under one roof, both the mechanical and the electrical aspects, undeniably contributes to the economically interesting and fast solution that could be offered. The machine was dismantled on site and transported to the workshop in Zwijndrecht. There, 2 separate teams worked on the machine, a mechanical and an electrical team with a project manager who monitored the whole operation and provided the customer with daily updates.

                    Were there other possibilities for this paper manufacturer than using Maintenance Partners for the maintenance of this machine, including the rewinding of the hairpin coils? As long as there is a choice to recover, there are also other players on the market. However, with the combination of expertise in both mechanical and electrical fields and the possibility of producing spare parts by itself, MP can offer great added value.

                    Moreover, years of experience in working with rotating machines ensure an ideal before and after process. From electrical measurements, parameter recording and problem analysis, to inspections, dimensioning and data recording for a 3D drawing, to the production of spare parts and rewinding, each phase of the preparation contributes to controlled execution of the maintenance procedures. When the installation is reassembled at the customer’s premises, after maintenance, the paper manufacturer has also completely modernised the generator protections.

                     

                    Pollution

                    It goes without saying that it is the customer himself who decides on the steps he takes for the maintenance of his machinery. Nevertheless, a proactive maintenance partner can be of inestimable value. At the premises of this paper manufacturer, a huge contamination of the generator was found during a visit to the site, which was not actually going to be repaired. However, due to the state of the turbo machine, local discharges occurred between the coils and the mass and between the coils themselves. If nothing is done about these risks, at some point, it could have a decisive impact on the mass. The result is a damaged insulation system which can cause production to stop suddenly. This large and above all sudden cost of externally purchased electricity would be much higher than having a generator repaired.

                    An alternative that the customer could have opted for was, of course, the complete replacement of the old machine. However, this is an operation that should not be underestimated, with a considerably longer delivery time than an extensive overhaul.

                     

                     

                    Result for the customer: Ready for the future

                    At the beginning of March, the generator was delivered by MP, after it was reassembled at the customer’s site and put back into operation by MP’s start-up engineer. This means that the entire process from the first contact with the customer to the final delivery took 9 months. In the shortest possible time, after thorough maintenance and rewinding, the customer was able to continue with his existing extremely solid machines.

                    The future was also considered. Maintenance Partners has carried out a number of works on the machines that make it possible to monitor the machine remotely in the long run and thus to guide the customer as a kind of external helpdesk.

                    In one single project, an old machine was upgraded to today’s specifications and prepared for the future.

                      Long Term Service Agreements for Steam Turbine Generator sets

                      A company that operates steam turbine generator sets (STG) relies on the stability of their assets to assure the continuity the plant’s activities. To assure this continuity, steam turbine generator sets need, as all equipment does, to be maintained regularly to prevent issues that could lead to breakdowns. For this purpose, Maintenance Partners has developed a specific Long-Term Service Agreement for steam turbine generator sets that unburdens the client completely.

                      Moreover, long term service agreements can be tailored to suit the needs of our customers. 

                       

                      LTSA

                      An LTSA is an agreement between MP and the customer that can run for 3, 6, 10 or more years for the maintenance of the complete steam turbine, gearbox and generator. All the maintenance that needs to be done on the turbine-generator set during this period is included, such as the minor or major overhauls and the annual inspections.

                      In case of unforeseen problems, LTSA customers have the advantage that MP knows the installation very well and that MP can intervene quickly. Response times in case of emergency can also be defined in the LTSA.

                      Generally, the supply of spare parts is also included in an LTSA. This offers customers the convenience of knowing in advance what the lead times and prices are for spare parts that are critical for maintaining the turbine-generator.

                       

                      MP Connectivity (available separately)

                      MP Connectivity is a package that synchronizes connections to all relevant turbine equipment (eg. turbine controller, process PLC, electric protections, excitation system, vibration monitoring). It also establishes a connection to a cloud based database where historical data is recorded.

                      MP Connectivity’s very high data acquisition rate of 100 ms allows troubleshooting for advanced trips and failures by our experienced turbine and generator specialists.

                       

                      Available after 2021: 24/24 Helpdesk (only in combination with MP Connectivity and LTSA)

                      When MP Connectivity is set up, the LTSA can also be extended with a 24/24 helpdesk service: a dedicated department that is available 24/7. This means that – even at night – a 24/24 Helpdesk client can contact MP and an engineer can remotely access the control panel of the steam turbine generator in case unexpected problems occur.

                      Based on the information gained from this platform, the MP-engineer can give instructions to the local operators on how to fix the problem, ensure continuity and decrease revenue losses. This service truly connects MP support to the client at any time, even when the MP staff is not present on site.

                       

                      P4A (available separately)

                      P4A is a predictive system that checks and follows up on the main parameters such as temperature, vibration, performance, etc. of the turbine and generator. P4A can be bought as a standalone service, but can also be used combination with MP Connectivity.

                      The system correlates data and warns in advance when problems will occur so they can be prevented instead of cured, which again is more cost effective for the client and simply more efficient. P4A offers:

                      • Big Data Collection
                      • Statistical Correlations between relevant parameters
                      • Efficiency Calculation Model
                      • Study of Historical Data
                      • Dashboards to visualize data
                      • Predictive Maintenance

                       

                      Customer Benefits

                      An LTSA is, apart from the certainty that a steam turbine generator set is well looked after, also a cost-effective partnership. For the running of the agreement the pricing is fixed. That way the owner can take his mind of his steam turbine and count on MP to keep it maintained.

                      • Clear view of costs during LTSA contract period (minor/major overhauls & inspections)
                      • MP Connectivity
                      • 24/7 Service support
                      • Predictive Maintenance

                      Signing a long-term agreement with MP means stepping into a partnership with a company that is as professional as it is reactive. Thanks to the well-equipped workshop and the state of the art technology Maintenance Partners manages to continuously offer the all-round service the customers are used to from their partner in maintenance.

                          Alstom TM2 Steam Turbine Case: Why maintaining your machinery is the only option

                          When a company depends on large machinery, e.g. for generating electricity, it is never safe to gamble on the health of these machines. Steam turbines need to go into maintenance occasionally. Maintenance Partners France recently solved complex problems for a company that tried to push the limits of an Alstom TM2 Steam Turbine.

                          Steam Turbine Specialists

                          MP France, the French branch of Maintenance Partners, is located in Nantes and employs close to twenty people. The unit that joined the MP family in May 2016 is specialized in steam turbines and is, just as big brother MP Belgium, not only a partner in maintenance to its customers but also an expert that can identify and resolve complex problems.

                          Alstom TM2 Steam Turbines

                          The Alstom TM2 steam  turbine that would be subject of this maintenance is an atypical machine. It has two rotors, one high pressure and one low pressure, and is mounted in a barrel.    

                          The machine needs to be mounted in a specific way and to assemble it special tools are needed. In addition to the atypical design of this turbine, the Alstom TM2 is characterized by the honeycomb packing seals that are used to avoid steam leaks and provide a very good efficiency. These seals require adapted start up procedures when they have been replaced.

                          Postponed Maintenance

                          A company, that has been a customer of MP France for over 10 years, was contacted in 2017 about the six-year maintenance of their Alstom TM2 steam turbine that was due at the beginning of 2018. The customer however decided to postpone this overhaul.

                          The last major overhaul on the customer’s Alstom TM2 was performed in 2011. By postponing the next overhaul, the customer took a risk that was strongly advised against by the engineers at MP France. In addition, the customer was also late in ordering the spare parts. These two risk factors combined resulted in a machine shutdown due to high vibration and a long-term shut down.

                          In the beginning of 2018, the customer contacted MP France about vibration problems. They didn’t want a large intervention at that time either, so MP fixed as much problems as possible without opening the machine. The customer was told about the importance of opening everything up to do the complete maintenance. As the client refused, three or four small interventions were done, but at a certain point the client had no other option than to open up the machine and do the major overhaul they were contacted about the year before.

                          Major Overhaul & Problem Solving

                          When the machine was eventually opened, MP France found a lot of problems. One of the main issues was the alignment of the bearings and the internal parts.

                          Also, the turbine supports did not stand evenly on the  foundation. This also contributed to the vibration problems. The rotors, diaphragms and bearings were shipped to the workshop in Zwijndrecht for inspections and thorough corrections. The rotating parts were balanced at nominal speed in MP’s high speed balancing machine.

                          In meantime, the team on site fixed the problems with the turbine supports. The entire turbine was reassembled at the customer’s location and a successful commissioning and start up was done.

                          Conclusion

                          This case clearly shows that postponing minor or major overhauls  and delaying spare part orders can cause more problems and lead to more costs than it saves. Another conclusion can be drawn as well:

                          It is one thing to perform maintenance on a machine that functions well, but it’s a completely different story to do it on a machine that doesn’t work properly. Maintenance Partners has experience In both fields. It performs the easier replacing of parts to prevent issues on working machines, but also the much harder job of locating problems and solving them.

                            Special job: In-situ rewinding of generator aboard a vessel

                            Rewinding… Maintenance Partners knows all about it. Every year, at least 100 electrical machines are rewound in Maintenance Partners’ workshops. It is safe to say that MP’s rewinders excel in their profession. Perhaps for that reason, the team was asked to perform a very special task.

                            MP was selected to rewind a high voltage generator in the engine room of a ship: a unique project.

                            The ship is an offshore supply ship that is used to support offshore oil platforms and the installation of wind turbines at sea.   

                            A generator manufacturer (OEM) contacted Maintenance Partners in August 2018 about the repair of a 5134 kVA generator with a voltage of 6600 volts and a speed of 720 rpm at 60 Hertz. This generator is one of three identical generators aboard that provide the ship with electricity. The generator had failed and the other two weren’t in perfect condition either. Because of this, the ship could not operate at full capacity.

                            The generator’s problems were caused by the use of magnetic wedges that keep the windings in the slots. This type of wedge is mechanically weak and degrades over time. One of the degraded locking wedges had come loose and was dragged along by the rotor which damaged the insulation of the winding as a result.

                             

                            Crucial Preparations

                            In-situ rewinding aboard a ship is very different from rewinding in the workshop. The fact that the engine rooms of this type of ship are crammed with machines and equipment causes the generator to be fixed in its position. Moving the ship to a dry dock and removing a part of the hull was not an option for the customer as the ship could not be taken out of service for a long period of time. In this case, the shipping company choose to repair the generator aboard, even if in difficult circumstances. Before the works could begin, the rotor had to be removed. But there was not enough space so a couple of pumps had to be removed and a hole was cut in one of the sidewalls.

                            The team then proceeded to inspect the generator with a borescope. During the inspection, the stator core was also checked for short circuits. The stator core turned out the be in good condition so the rewinding could proceed.

                            For projects like these, a highly detailed preparation is crucial. Not a single item can be forgotten as missing tools and equipment are disastrous for the completion of the job.

                            These generators are constructed with a soft coil system and are entirely impregnated under vacuum. A soft coil system under VPI is difficult to remove.

                            Re-engineering to resin rich coils

                            The removal of the coils took the most time. The new windings can not be treated in the same way as there is no vacuum impregnation tank available. To overcome this, the customer agreed to modify  the soft coil system to resin rich hard coils. The resin rich system is an older design than the soft coil system, but equals its modern counterpart in quality. The reverse engineering of the coils was performed inhouse by Maintenance Partners. After the rewinding, the customer and a classification society had to approve the repair as original manufacturer to allow the ship to be insured again.

                            Result for the customer: “a piece of art”

                            Thanks to the in-situ rewinding aboard the ship, a repair in the dry dock could be avoided and the ship could return to service in a shorter time.

                            The successful result of this intervention allows Maintenance Partners to show its expertise and eagerness to step out of its comfort zone. The customer called the result  ‘’a piece of art’’.

                                Special project: Full refurbishment of 15 high voltage motors

                                Not all motors are the same. While Maintenance Partners is a jack of many trades in terms of the repair and rewinding of motors for a wide range of customers, some projects require special attention. At the start of 2017, a European energy company with multiple power plants contracted Maintenance Partners. A customer with a special project related to high voltage motors.

                                Previously, Maintenance Partners had already regularly repaired electric motors for the energy company, and carried out maintenance work as a contractor. Now a different question was raised: fifteen high voltage high voltage motors needed a total refurbishment, which meant a full stripping and renewal of the machines.

                                Refurbishment book

                                A special project requires a special approach. While a test report is issued to the customer for standard revisions or rewinds, for this project a refurbishment book is drawn up for each machine: a 50-page document that, in consultation with the customer, lays down all wishes regarding the refurbishment. This book serves as a guideline that is strictly followed by all employees who work on the machine during the different phases of the refurbishment.

                                Process 

                                There are many steps between reception of the machine in the workshop and its completion. The motors, which are sent by the customer in stages to Maintenance Partners, are first subjected to a series of tests, during which all necessary information is recorded. Mechanics then fully disassemble de motor, measuring all fits. A magnaflux inspection is carried out on the shaft, looking for cracks in the material. An NDT examination is carried out on the flanges for the same reason. In addition, the winding is evaluated (number of turns, thickness of wire, rotations per minute). Various hold points and witness points are scheduled during this process: points at which the customer comes to witness, when the motor is disassembled.

                                Once the winding is removed from the stator, a core test is performed. The customer has asked for a new stator core, but new coils and bearings are also always provided. The entire machine is also sandblasted and gets a new coating to prevent corrosion. The core package is measured, built, lasered and stacked in the blasted casing.

                                This is followed by the rewinding and coupling of the electrical ends to the coils, and electrical circuits are coupled in the same way as before the disassembly. Various tests and measurements are also carried out during these phases. Finally, the motor goes to the VPI tank, where the windings are impregnated under vacuum.

                                After the rotor is installed again, various tests are performed to check whether everything was reinstalled correctly.

                                As good as new

                                Every motor is thus given a full makeover, that gives the customer a guarantee that the machines will be operational again for a longer period of time. An alternative, of course, is to order new machines. However, this process often takes over a year, because – in particular for these types of motors – nothing is standard, as everything needs to be tailor-made.

                                Refurbishing is therefore faster, and is certainly equally efficient. A refurbished motor is not inferior in terms of quality to a new motor, and often operates better than when it was first taken into use, especially the insulation thanks to the use of the best materials. The result is a motor that is as good as new, or even better!

                                High voltage in the industry

                                This also takes away the concern shared by many companies that use high voltage motors, and that are wondering whether their machine will be of the same quality after the repair or rewinding. By the way, it is not just energy company that can bring their high voltage motors to Maintenance Partners. Other industries, such as petrochemicals, food, steel and rubber production can also benefit from the solutions offered by Maintenance Partners. These motors, which may be critical to the production process, require extra attention and knowledge.

                                Maintenance Partners has this knowledge. The specialist in electric motors has the people and experience to take on larger scale projects.

                                  Mr.Ms.

                                   

                                   

                                  Five Questions about Rotor Inspections and Repairs

                                  The rotor is one of the most critical components of any turbomachine.  A rotor is subject to many factors that influence its condition, such as gases or steam, vibrations, pollution, abrasive parts in the medium, temperature variations and starts/stops. Over time, these factors will lead to erosion, corrosion, cracks or even broken parts.

                                  Rotor inspections can detect faults at an early stage and repairs can prevent unplanned outages. That is why rotor inspections are an essential part of maintenance programs for turbomachinery.

                                  We regularly receive questions about rotor inspections and repairs and hope to answer the most frequently asked questions below.

                                  Did you know that Maintenance Partners performs rotor inspections according to the API687 standard?

                                  To ensure the quality of rotor inspections and to clearly define the contents of a rotor inspection, Maintenance Partners has implemented the API687 for rotor inspections of centrifugal compressors, axial compressors, steam turbines, gears, expanders and positive displacement rotary screw type compressors.

                                  What is API687?

                                  The API687 standard has been drawn up by American Petroleum Institute and is a recommended practice for repairing rotors. API687 is the only written standard covering rotor inspection and repairs in all aspects and defines what vendor and equipment owner responsibilities are during the inspection/repair process. Inspections and repairs generally follow the following sequence:

                                  During the entire process the equipment owner has the lead for approving job scopes, work procedures, welding procedures and quality plans. The vendor shall have all details of repairs, material certificates and records of heat treatments available for the equipment owner.

                                  API divides the inspection process into two phases:

                                  • Phase I, Inspection: Assembled Rotor
                                  • Phase II, Inspection: Disassembled Rotor
                                    Phase I inspection Phase II inspection
                                  Unload and unpack rotor
                                  Conduct incoming visual inspection
                                  Protect all critical areas & clean by glass peen blasting
                                  Perform visual inspection after cleaning
                                  Perform NDT
                                  Check and record dimensions, electrical & mechanical runouts
                                  Perform low speed balancing check
                                  Prepare Phase I inspection report
                                  Disassemble rotor (blades or impellers)
                                  Perform visual inspection of all removed parts
                                  Measure all shaft component sizes
                                  Perform NDT on all removed parts
                                  Prepare Phase II inspection report

                                   

                                  How is API687 implemented at Maintenance Partners?

                                  Embedding the API687 workflow in our ISO9001 procedures has resulted in standardization in sales and operations. Maintenance Partners uses standard job scopes, quality plans, procedures and reporting templates.

                                  What if a rotor needs to be repaired?

                                  Maintenance Partners’ rotorshop is fully equipped with state of art equipment for all types of rotors. Depending on the condition of the rotor, the rotor repair may include the following:

                                  • Rotor journal repairs by welding, laser cladding or HVOF coating
                                  • Spare parts: manufacturing of new impellers, shafts, blades, diaphragms, blade carriers, etc.
                                  • Reblading
                                  • Replacement of seal strips
                                  • Low speed balancing
                                  • High speed balancing
                                  • Over speed test
                                  • Impeller spin test
                                  • Coating application on compressor impellers for corrosion protection, reduction of fouling rates and a smooth surface, resulting in an increased efficiency

                                  Are spare parts for rotors available?

                                  Lead times of parts can be very long. To overcome this, Maintenance Partners offers reverse engineering. Our engineering capabilities enable us to carry out the entire re-engineering process internally. From scanning, redesigning and modeling to manufacturing.

                                    Extreme re-engineering and repair of KKK CF4G single stage steam turbine

                                    Maintenance Partners was contacted by a customer after the breakdown of a single stage steam turbine. The damage to the turbine was severe: the bearing housings, the pinion and bull gear teeth were damaged. To make matters worse, the top casing was cracked. Several parties advised the customer that the turbine was a total loss and the only solution was to replace the entire turbine.

                                     

                                    Maintenance Partners, however, never says no to a challenge. Our experts found a solution and proposed the customer to repair the turbine. Repairing the turbine proved to be much quicker and more economical than replacing the turbine by a new one.

                                    Reverse engineering and Repair

                                    After the customer accepted the repair proposal, the turbine was disassembled in MP’s workshop and our engineers started the reverse engineering process. As the turbine had been running for over 4 decades, drawings were not available. The damaged parts were scanned in 3D and manufacturing drawings were prepared.

                                    The pinion and bull gear could not be refurbished and new parts were manufactured using the drawings. The four bearings and bearing housings were renewed entirely as well.

                                    A spare turbine wheel that the customer had in stock was mounted on the shaft with the pinion. The assembled rotor was balanced at low speed.

                                    To restore the casing, a material analysis was performed to determine the alloy of the existing material. A new piece matching the material was manufactured to fit the gap in the casing. The casing was pre-machined before stitching the new piece to the casing. Finally, the casing was machined to original dimensions.

                                    When all parts were manufactured, the turbine was assembled and ready for commissioning onsite.

                                    Result for customer

                                    The single stage steam turbine was considered to be a total loss, but Maintenance Partners found a solution that was quicker and more economical for the customer.

                                      New workwear for MP!

                                      The new workwear will be introduced in the coming weeks. Maintenance Partners wanted to change the traditional blue overalls for more modern workwear that matches the colors of MP’s corporate identity.

                                      After comparing and testing different overalls, a choice was made based on the following criteria:

                                      • Stylish appearance, two-tone, contemporary designs with colored details, contrasting stitching and high-quality color fastness.
                                      • Very practical: Multiple convenient pockets offer optimal space for tools
                                      • Freedom of movement and comfortable to wear: use of tricot material from under the armpits to the shoulder blades.
                                      • Strong and robust: high quality wear-resistant materials, and with reinforcements in places that are prone to wear

                                       

                                      Safety

                                      For Maintenance Partners it is important that workwear meets the highest demands and safety standards. The field overalls are equipped with signal bands on the sleeves and trouser legs. This increases the visibility of our employees, but also offers improved safety over a flammable fluorescent vest.

                                      Besides this, the overalls for our field service teams are made from Delta Multiprotect fabric. This material has been developed for maximum protection, comfort and style. The workwear is flame retardant, anti-static and protect against electric arc and chemicals

                                        Production processes continuously generate data (vibration, pressure, temperature, flow, etc.). Besides this, an enormous amount of information is available from various sources, such as reports, documents, environmental factors and human behavior.

                                        Out of all available data, companies only use 1/3 for analysis. The potential of the remaining 2/3 is left untapped because the current tools aren’t powerful enough or are inadequate.

                                        Maintenance Partners offers auto-learning analysis software that compares and analyses unlimited sources of live data, historic data and theoretic models.

                                          Reverse Engineering of Turbo Expander

                                          A European fertilizer manufacturer contacted Maintenance Partners to overhaul a multistage turbo expander. The expander was built in 1965 and was showing severe signs of wear and tear after years of use.

                                          Turbo expander specifications

                                          • Manufacturer: Worthington

                                          New rotor vs repaired rotor

                                          The rotor was considered irreparable by the original equipment manufacturer and a new rotor was offered. However, the delivery time of the new rotor was expected to be around 2,5 years. For the customer this was not acceptable and Maintenance Partners was contacted to check if a repair was possible in a shorter time frame.

                                           

                                          Repair

                                          Maintenance Partners offered to repair the turbo expander in 8 months time. The repair consisted of:

                                          • Replacing 8 tie bolts
                                          • Reblading 8 rows including riveting
                                          • Laser cladding and grinding of 2 stub shafts
                                          • Producing 3 new diaphragms
                                          • Repairing 3 old diaphragms
                                          • Renew white metal bearings
                                          • High speed balancing
                                          • Producing new steam turbine rotor for the same train

                                           

                                           

                                          Engineered Services

                                          Reverse Engineering & parts manufacturing

                                          Combining process and equipment knowledge allowed Maintenance Partners to re-engineer new diaphragms, bearings, labyrinths, nozzle and tie bolts and a complete new steam turbine rotor. In addition, all parts were manufactured in MP’s machine shop.

                                          Rotor dynamic model & high speed balancing

                                          To improve the turbo expander’s reliability a rotor dynamic model was created. This model is used to calculate right bearing clearances and to verify the required bearing type. It also predicts the rotor’s dynamic behavior at nominal speed.

                                          This particular rotor had never high speed been balanced before (only incremental and low speed). This model helped to achieve very low vibrations of 0,06 mm/s rms during the final run in Maintenance Partners’ Schenck high speed balancing machine.

                                           

                                           

                                          Benefits for the customer: Quick Delivery & Machine runs better than before

                                          Instead of the 2,5 years it would take to order a new rotor, Maintenance Partners got the turbo expander running in perfect condition 8 months after the order was placed. The high speed balancing has significantly reduced rotor vibrations, as opposed to before the repair.

                                                Durability Improvements for Vacuum Pumps

                                                Fouling is a common problem that affects vacuum pumps, resulting in unbalance, vibrations and reduced flow.

                                                Besides this, vacuum pumps can be damaged by cavitation and aggressive or acid liquids. After sandblasting, the damage to the rotor is clearly visible:

                                                These problems have a negative impact on the pump’s reliability and expected lifetime. This can lead to unexpected outages. To keep vacuum pumps running, a good maintenance approach is a must.

                                                Maintenance Partners offers a variety of services such as inspections, overhauls and durability improvements for vacuum pumps:

                                                Services | Overhauls & Repairs

                                                A repair or overhaul of a pump generally consists of an Inspection, Repair/Modification and a final Report.

                                                A standard overhaul at Maintenance Partners consists of:

                                                • dismantling
                                                • cleaning
                                                • inspection
                                                • Measuring clearances and dimensions
                                                • Replacing bearings, seals & parts
                                                • Assembly
                                                • Painting
                                                • Final control

                                                In case the pump is damaged, Maintenance Partners can cover all required repairs:

                                                • Chemical cleaning of pump
                                                • Coating of pump parts
                                                • Balancing of rotor
                                                • Polishing & redressing bearing place, sealing glands on both sides
                                                • Welding and machining of bearing places on both sides

                                                Services | Improved Durability

                                                To prevent unplanned outages, most of our customers choose to apply an anti-fouling coating on the inside of the pump during an overhaul. This coating has a very smooth surface which reduces the chance of fouling. Moreover, the coating offers an improved protection against wear and tear.

                                                Besides this, Maintenance Partners can apply hard wearing material to the bearing places.

                                                In general, our customers experience that these improvements can double the meantime between failures for vacuum pumps.

                                                  Repairs of magnetic couplers for motor driven reels

                                                  Maintenance Partners offers a full solution for the inspection, repair and rewinding of magnetic couplers that are used in motor driven reels (gantry cranes, port cranes, loaders, unloaders, stackers, …).

                                                  We repair magnetic couplers for marine & offshore clients as well as for industrial customers.

                                                  To ensure functionality after the repair, all magnetic couplers are fully tested before installation.

                                                  Inspections

                                                  The first step when repairing a magnetic coupler is the inspection, this includes:

                                                  • Torque check
                                                  • Coupling ring inspection
                                                  • Backstop bearing inspection
                                                  • Air gap inspection

                                                  When the inspection is finished, an inspection report is drawn up with recommendations for repair. Besides the coupler, Maintenance Partners also offers inspections & repairs of electric motors and gearboxes.

                                                   

                                                  Overhauls or Repairs

                                                  After approval of the recommendations for repair, the execution of the repair or overhaul works begins. The scope of work may vary, but can include:

                                                  • Disassembly
                                                  • Inspection and cleaning
                                                  • Assembling (including new bearings and seals)
                                                  • Torque adjustment
                                                  • Painting

                                                  The final report is written after testing and includes measurements from before and after the repair. When possible, recommendations for operating, inspecting and maintenance are also included, resulting in more reliable operations and less unforeseen breakdowns.

                                                   

                                                  Rewinding

                                                  In case of severe damage to the magnetic coupler, we rewind the inductor. This includes removal of the old windings, cleaning of the inductor housing and installing the new windings. A high quality varnish resin is applied to protect the windings against humidity and corrosion.

                                                   

                                                  Testing

                                                  All magnetic couplers that are overhauled by Maintenance Partners are thoroughly tested to ensure the quality before re-installing at the customer’s site or vessel.

                                                   

                                                  Exchange Service

                                                  When a magnetic coupler breaks down, a spare component might not be immediately available. To keep your equipment up and running, we offer an exchange service for magnetic couplers. The benefit of this service is that a broken coupler can quickly be exchanged for a refurbished one.

                                                      How well do you know your wind turbines?

                                                      Being the owner or operator of a wind farm, regardless of the long-term contract you have, you should be able to know in what state your turbines are, how much they are going to produce and what benefits you will receive from that production.

                                                      But are you sure that you know what’s going on in your machines now and in the future? Does your O & M tells you everything you need to know to estimate future costs in a better way?

                                                      Many wind turbine owners have an availability higher than 97%, is this enough? When production declines, can you be sure it is due to a “bad wind year” or are there other hidden causes? Don’t you think your machine could be producing more?

                                                      The world of wind turbine maintenance is changing and at Maintenance Partners we are anticipating these changes:

                                                        Engineered Services: Upgrade of Damaged Gamesa G90 nose cone structures

                                                        Damage was detected on the nose cone structures of 7 Gamesa G90/2000 wind turbines in a French wind farm. Instead of just repairing, Maintenance Partners used its vision of Engineered Services to improve the lifetime and reliability of the equipment.

                                                        Maintenance Partners - Re-engineering of Gamesa G90 nose cone structures 01Cause of nose cone structure damage

                                                        Wind turbines are subject to continuous vibrations. Due to poor design and quality, this type of wind turbine is prone to nose cone structure cracks due to vibrations. These cracks can form a hazard for the structural integrity of the wind turbines. Moreover, the damage could lead to potentially very large repair costs and turbine downtime in case of a complete nose cone replacement.

                                                        Inspection

                                                        Maintenance Partners - Re-engineering of Gamesa G90 nose cone structures 02To determine the extent of the damage, Maintenance Partners was asked to inspect the nose cones of all turbines in the wind farm.

                                                        MP’s field teams carried out visual inspections and used non-destructive testing techniques to check the welds for cracks. The inspections showed cracks developing in the connecting welds between the tubes that form the nose cone structure.

                                                        After the inspections, a detailed report with repair proposal was drawn up. The repair proposal offered the most cost effective solution to the client in which production losses were reduced to a minimum.

                                                        To correct the nose cone structure problems, MP’s Engineering department has developed an upgrade method with improved solution to safely extend the lifetime in the long run (until decommissioning of the wind turbine).

                                                        Repairs: Temporary Safety Kit

                                                        Due to the winter windy season coming up, to reduce the outage time to a minimum and to avoid further damage, MP proposed the customer to repair the nose cone structure in the shortest possible timeframe and on the shortest notice. First, Temporary safety kits were installed to immediately reduce the hazards caused by this damage.

                                                        Structural Upgrade

                                                        After installation of the safety kits, MP implemented the upgrades to each turbine. The upgrade included:

                                                        • Safety kit
                                                        • Dismantling
                                                        • Cleaning
                                                        • Replacing 6 damaged structural tubes for each nose cone structure
                                                        • Welding of structure using special purpose procedures
                                                        • Application of Strengthening plates
                                                        • Installation of additional calipers
                                                        • Passivation for corrosion resistance
                                                        • NDT including Cofrend 2 welding certification
                                                        • Conformity certificate
                                                        • Material certificate

                                                        Because all works had to be performed onsite and inside the nacelle, elaborate safety measures were taken to ensure the safety of all workers onsite and the turbine itself.

                                                        Afterwards, the turbines were recommissioned and started up by MP’s field team.

                                                        Results for Customer

                                                        After applying the upgrades, the customer is now sure that the nose cone structures are solid and that they will last until decommissioning.

                                                          Interview: The Strength of Engineered Services

                                                          Maintenance Partners - Insights - Interview CEO Wim Schelfaut Engineered Services FeaturedTechnological developments rapidly change the jobs of maintenance specialists. How is it possible to put all these developments to the customer’s advantage?

                                                          Maintenance Partners (MP), the maintenance specialist in the field of industrial rotating machines for 15 years now, provides more than maintenance, repairs and overhauls. MP provides engineered services, a total maintenance package customised to the customer’s production process and expectations. MP uses modern, state-of-the-art tools for this comprehensive service.

                                                          Director Wim Schelfaut: “Many of our customers have machines that are 40 to 50 years old. Old, but high-quality, in other words, which in most cases still work perfectly. The engineered services we offer allow us to optimise the maintenance which means the customer does not have to make major investments in new machines. We draw up an action plan for the maintenance of the existing machines and take into account all parameters that affect the operation of the machine and the production process. In practice this means: no useless, unprofitable repairs but customised solutions and thinking along with the customer.”

                                                          15 MVA ELIN generator rotor fully rewound in 8 weeks time!

                                                          MP’s electrical specialists have fully rewound a 15 MVA ELIN generator rotor in 8 weeks time.

                                                          ELIN DTG 100/2-227 Generator from 1966

                                                          • Manufacturer: ELIN
                                                          • Type: DTG 100/2-227

                                                          • Year: 1966

                                                          Customer’s request

                                                          The customer’s original request was to replace the original retaining rings by new retaining rings in an anti-magnetic material. MP was asked to re-engineer, manufacture and install the new retaining rings. The anti-magnetic characteristics of this material reduce leak flux (electromagnetic losses) in the retaining rings. Moreover, this material is less prone to corrosion than the original retaining rings.

                                                          Both the stator and rotor were transported to Maintenance Partners’ workshop in Zwijndrecht for overhauling.

                                                          When the rotor was dismantled, MP’s engineers found that the rotor’s insulation material was severely deteriorated. A full rewind turned out to be the only solution to ensure safe and reliable operation.

                                                          Rotor

                                                          Rewinding the rotor was a very extensive project that included 300 turns that had to be installed and insulated individually.

                                                          The generator is a critical machine in the customer’s plant, because of this teams of 3 specialists worked in 2 shifts to finalize the rewinding within 8 weeks.

                                                          Engineered Services: Improvements

                                                          Besides the re-engineering of the retaining rings, Maintenance Partners’ engineering department applied two other important conceptual improvements:

                                                          • The rigid connection between the north-south was replaced by a flexible connection
                                                          • In the original design, there was no room for the windings to expand, the modifications now allow this

                                                          These improvements are a good example of MP’s Engineered Services: offering more than just repairs. We do so by applying high quality materials, improving designs and evaluating the functionality of rotating machines within the process.

                                                           

                                                          Stator

                                                          During the rewinding of the rotor, the stator was also overhauled. To make the overhang more rigid, epoxy was injected and the original wooden winding supports were replaced by expoxy supports.

                                                          Balancing

                                                          After installation of the retaining rings, the rotor was ready for balancing in MP’s high speed balancing machine. During the balancing, Repetitive Surge Oscillograph (RSO) measurements were conducted to detect any short circuits.

                                                          Result for the customer

                                                          Thanks to the reverse engineering of the rotor and stator, the generator’s relability is at the highest level. In addition, the project planning of this project has helped reducing the downtime of the generator to a minimum.

                                                            Re-engineering has increased the reliability of reciprocating compressor cylinders and allowed our customer to increase production. The cylinders are part of ammonia gas (NH3) compressors that originate from the 1960’s. Over time, the ammonia gas has deteriorated the cylinders. The valve seats have been damaged and because of that the reliability of the machine could not be granted.

                                                            New cylinders for this compressor were not available. To keep the compressors running, the customer contacted Maintenance Partners.

                                                            Customer Request: Extend Lifetime at increased production

                                                            Our customer did not only ask us to renew the cylinders, but also asked to extend the lifetime at an increased level of production. This question fits seamlessly with our vision of Engineered Services maintenance and reliability solutions for rotating equipment are the foundation for improving reliability, output and efficiency of the production process.

                                                            Re-Engineering

                                                            Study of materials
                                                            MP’s engineering department first performed a re-engineering study to define the opportunities for improvement. The first step was an extensive material study to determine which material was the most fitting for the customer’s demand. The new material had to be able to resist the product and an increased pressure, allowing for the increase in durability.

                                                            Afterwards, the existing compressor was fully scanned in 3D, after which technical drawings were made. The drawings were used to make a casting model and draw up the casting procedure. The pieces were cast by an external supplier.

                                                            Machining

                                                            The castings were checked for dimensions and any casting errors. Our engineering department created the necessary procedures for machining the castings and special tools were developed for the machining.
                                                            In MP’s workshop, the castings were machined by the Tos Varnsdorf boring machine. A CNC controlled head was used to machine the inside of cylinders.

                                                            Quality check – Pressure Testing

                                                            When the machining was finished, each cylinder was tested at cooling water presssure (16 bar) and tested at process pressure (162 bar). After the pressure tests, the cylinders were transported to the customer for installation onsite by MP’s field teams.

                                                            Benefits for Customer

                                                            Thanks to the re-engineering of the cylinders, the compressors have been fully adapted to the customer’s process and product. Moreover, the reliability is also guaranteed at an increased pressure and production.

                                                              Over 7% efficiency increase after abradable sealing modification on GHH axial/radial air compressor

                                                              Maintenance Partners - Abradable Sealing Upgrade - GHH Axial Air Compressor - 3D Scanning of Rotor for re-engineering 920Maintenance Partners has recently applied an abradable sealing modification to a GHH axial/radial air compressor in combination with one expander wheel. The compressor is used in a nitric acid train of a Turkish fertilizer plant. This upgrade has resulted in an efficiency increase of 7,36%. Our customer faced a growing demand for fertilizer products and contacted us to increase the efficiency of a GHH axial/radial air compressor.

                                                              The GHH axial/radial compressor runs at 5250 RPM and was manufactured in 1967. The compressor has been running for almost 50 years and is one of the plant’s most critical machines for the production of various nitrogen- and urea based fertilizer products.

                                                               

                                                              Abradable Sealing Modification

                                                              A turbo compressor’s overall efficiency is greatly influenced by the internal recirculation of the compressor gas, or Internal Recycle Flow. To solve this, Maintenance Partners offers a modified sealing system on the radial impeller balance piston location to significantly reduce internal recirculation.

                                                              Maintenance Partners - Abradable Sealing Upgrade - GHH Axial Air Compressor A 920The reduction in recycle flow is the result of minimizing the clearances between the labyrinth and the rotor. This is achieved by removing the existing stator labyrinths, installing new labyrinth seal strips on rotor parts and installing abradable seal rings in the casing on impeller eye and balance piston location.

                                                              All parts required for the modification were re-engineered and manufactured by Maintenance Partners.

                                                              The new sealing system was installed onsite during a planned three-week shutdown of the fertilizer plant. During the installation, the team found severe alignment problems which lead to high vibrations. The rotor was re-aligned which solved vibration problems.

                                                              As the compressor was partly disassembled during the shutdown, the occasion was utilized to scan the blade carrier in 3d for re-engineering and manufacturing later.

                                                              Other improvements:

                                                              Besides the application of the abradable sealing system, the rotor was also coated (radial impeller & axial blades) to be protected against corrosion and to reduce fouling. The coating used is an aluminium filled chromate / phosphate bond coating that can withstand temperatures up to 260 °C.

                                                              This specific coating has a very smooth surface that contributes to performance improvement and fouling rate reduction.Maintenance Partners - Abradable Sealing Upgrade - GHH Axial Air Compressor rotor high speed balancing 920

                                                              To increase flow, the compressor’s inlet was fitted with 250kW booster fan in the past. Thanks to the abradable sealing modification, the booster fan is no longer required and can be shut off, allowing our customer to reduce electricity consumption. The plant is operating 24/7 all year round this means that an energy reduction of 2 190 000 kWh per year can be achieved (250kW * 24 hours * 365 days) when the booster fan is not in use.

                                                              Measurements conducted and provided by our customer show an efficiency increase of 7,36% after the abradable sealing modification. This increase results in an increase of discharge flow from 89 134m³/hour to 95 700m³/hour. The discharge flow measurements were taken at the same inlet temperature and running speeds:

                                                                In the manufacturing of LDPE (low-density polyethylene) using the autoclave process, stirrer motors (or chemical reactor vessel motors) are critical to the production. Breakdowns immediately result in economic and production losses. Maintenance Partners has decades of experience in repairing and rewinding LDPE autoclave reactor motors for leading LPDE manufacturers throughout the world.

                                                                Our extensive know how and engineering capabilities ensure that the optimal repair methods are selected at all times and that the stirrer motors perform according to specifications.

                                                                 An LDPE autoclave reactor is a particularly harsh environment in which the stirrer motor is submerged in liquid ethylene. The stirrer motor is used to mix the LDPE inside the reactor vessel. Inside the reactor vessel, pressures up to 2000 bar are required to achieve optimal conditions for the production of LDPE at the desired flow. Temperatures inside the reactor reach up to 290°C at the bottom zone. These conditions are extremely tough and challenge the lifetime of all components.

                                                                 

                                                                Maintenance Partners - LPDE Autoclave Reactor Motor - Damaged BearingCommon Problems

                                                                Bearing Failures

                                                                To prevent any oil or lubricants from polluting the product, the motor itself is cooled and lubricated by injected gasses. The downside of this lubrication method is that the lifetime of the bearings is reduced significantly. Thus, bearing failures are common causes for breakdowns of stirrer motors.

                                                                Decomposition

                                                                Due to the combination of high pressure and temperature, the LDPE autoclave process is prone to decomposition. Decomposition can be triggered by events in the production process. In case of decomposition, the product explodes, followed by a rapid pressure drop when the safety valve opens to release the product. The explosion and the pressure drop can severely damage a stirrer motor and a full inspection is advised to ensure reliable performance of the electric motor.

                                                                Preventive Maintenance

                                                                As stirrer motors are critical to the production process, preventive maintenance is inevitable to safeguard a reliable operation. Stirrer motors are swapped regularly with spare motors when the product is changed. Motors that have been replaced can be checked preventively. This includes electric and vibration measurements, a check of the winding for looseness and a bearing replacement.

                                                                Curative Maintenance – Rewinding

                                                                In case the motor does breakdown, Maintenance Partners is fully equipped to repair and rewind autoclave reactor motors. Maintenance Partners offers to rewind reactor motors with diamond coils. The insulation material and resin used by MP have been thoroughly tested and approved for use with ethylene gas and can withstand the conditions inside the autoclave.

                                                                Complete Renewal

                                                                More severe damages may require a partial or entire renewal of the motor. Maintenance Partners offers the renewal of key components of the electric motor such as the stator core, the casing and the rotor. The time to rebuild a motor is usually a lot shorter than the lead time required to order a new motor. As these motors are critical to the production process, many customers prefer rebuilding the motor when possible.

                                                                  Maintenance Partners Testing of Roots Blowers and High Vacuum Boosters (HVB) 920

                                                                  During the test, the blower is driven by an electric motor at variable speeds. This allows us to detect and resolve any oil leakages.

                                                                  Moreover, the driven test shows if clearances and correct timing gear adjustments are respected and if the mechanical seals are functioning properly.

                                                                  In short, testing guarantees that all blowers repaired by Maintenance Partners meet the highest quality standards!

                                                                  Maintenance Partners manufactures open and closed impellers (2D & 3D) as replacement components for centrifugal compressors and pumps. Our state of the art facilities and engineering capabilities enable us to carry out the entire process internally (from scanning, redesigning and modeling to manufacturing). We can supply single impellers as spare parts, but also completely assembled rotors.

                                                                  Preparation: Disassembly & Engineering

                                                                  Maintenance Partners Impeller Manufacturing - Incoming 920Disassembly

                                                                  After reception and dismantling of the compressor rotor in our facilities, a comprehensive non destructive inspection is carried out. Incoming inspections can include material analysis and dye penetrant-, ultrasonic- or magnetic particle testing.

                                                                  After NDT, a report and a repair proposal are made.

                                                                  When impellers are irreparable, a proposal is made to supply new impellers based on redesigning and 040_MP-19-05-2015-0040modeling.

                                                                  Engineering

                                                                  Depending on the customer’s needs and rotor application, the proposal can also include modifications and upgrades to improve durability and efficiency. Proposed optimizations are always based on process, operational & maintenance data.

                                                                  To determine which upgrades are feasible or necessary, our Engineering team uses fluid dynamic software as simulation tool to optimize the design and functionality. Maintenance Partners Impeller Manufacturing - Engineering 460Besides this, a dynamic rotor behavior analysis can be done. The dynamic rotor behavior analysis is based on a computerized simulation that calculates the effects of bearing design, rotor structure and process influences such as temperature, flow and fluid.

                                                                  Once the customer has agreed to the proposal, new materials are ordered. The engineering phase is completed by writing the manufacturing procedures and drawings.

                                                                  Manufacturing of impellers

                                                                  After the engineering phase, the manufacturing procedures and drawings are the foundation for the first step in the production process: the pre-machining of raw materials. Maintenance Partners’ workshop is equipped with state of the art equipment for welding, induction heating and final machining. This allows us to manufacture impellers at high precision.

                                                                  After final machining, the new impeller(s) and shaft are assembled. Impellers are generally shrink-fitted to the shaft according to pre calculated data considering the effects of interference stresses. Upgrades such as protective coatings can be applied after the rotor is assembled.

                                                                  Quality Control

                                                                  In case of a complete rotor, the complete assembly is subject to final non-destructive testing and high speed balancing in our rotorshop. High speed balancing is usually witnessed by the customer.

                                                                  Maintenance Partners Impeller Manufacturing - High Speed Balancing 920

                                                                    A waste to energy plant selected MP for the major overhaul of a 18MW Thermodyn steam turbine. Maintenance Partners’ short lead time and the ability to take care of the entire shaft (steam turbine, gearbox and generator) convinced the customer to award the contract to MP.

                                                                    12-day Pit Stop steam turbine overhaul

                                                                    Careful planning of works onsite and preparations in MP’s workshop allowed for a significant reduction of time needed to complete the major overhaul. Only 12 calendar days were required from turning gear to turning gear. Teams of 6 specialists worked 24/7 on the overhaul to ensure that the job was finished in time.

                                                                    Scope

                                                                    The original scope included a major overhaul of the steam turbine, gearbox and generator. In addition, the steam turbine rotor also required high speed balancing.

                                                                    Earlier inspections showed that the spindle and bushing had to be replaced. To ensure availability of the material, all raw material was ordered in advance. After disassembly, MP’s engineers re-engineered the spindle and bushing and the parts were manufactured in the workshop.

                                                                    During the major overhaul, damage to four valve seats was found. The damaged valve seats were exchanged. Besides this, the final (low pressure) blade stage was damaged. The blades were repaired by welding in MP’s workshop.

                                                                    The exchange and repairs were completed without any delays in the 12-day planning.Maintenance Partners 18MW Thermodyn Steam Turbine Major Overhaul - Rotor HSB 920

                                                                      Maintenance of 200 pumps

                                                                      The improvements have been realised within a contract in which maintenance activities & tasks have been defined and rates have been agreed for for standard overhauls. The contract concerns 200 volumetric pump units with motor drives between 30 and 400kW.

                                                                      The API pump units have been operating for 5-8 years in a petrochemical environment. The site is a Seveso facility where Atex regulations apply.

                                                                      How?

                                                                      Within the contract, Maintenance Partners is responsible for the total maintenance and availability of the units, each consisting of pump, coupling and motor. The maintenance activities are split into preventive & predictive maintenance and repairs:

                                                                      Preventive- & predictive maintenance

                                                                      Each pump unit is checked preventively every 4 months. The preventive checks include:

                                                                      • Visual check of oil levels and refilling where needed
                                                                      • Visual check of motor and coupling
                                                                      • Visual check for leakage at seals and flanges
                                                                      • Torque check of foundation and coupling bolts
                                                                      • Check of Mechanical Seal quench reservoir for volume and pollution
                                                                      • Check and record operating vibration levels
                                                                      • Check and record suction/discharge/flow/power parameters

                                                                      In addition, the alignment of each pump is checked annually and adjusted where necessary.

                                                                      An inspection report is drawn up for each check or inspection. The reports are checked and compared to the most recent predecessor and then communicated to the customer with recommendations, all reports are saved in a dedicated Customer Portal.

                                                                      When an inspection shows problems that cannot or do not need to be repaired immediately, the repair activity is planned for a suitable point in the future. In extreme and very rare cases, the pump and/or motor is removed for urgent overhaul or repair.

                                                                      Curative maintenance

                                                                      When repairs are necessary, the pumps and/or motors are repaired within 3, 5 or 7 working days (depending on the damage). Fixed rates have been agreed for onsite works, standard overhauls and specific activities such as delivery of certain spare parts.

                                                                      Mechanical seals in stock

                                                                      To enable us to provide a rapid turnaround, the most common mechanical seals are kept in  stock and are directly available. Stock Mechanical Seals include, Chetra, Burgmann and AES. Moreover, our relationship with other seal suppliers is such that the quickest possible delivery is guaranteed. This eliminates the long delivery time of mechanical seals when performing an overhaul and allows for quick re-commissioning of the pump units.

                                                                      Reporting & Evaluation

                                                                      In addition, the Customer Portal offers the possibility to track the maintenance record on the functional level as well as on the individual level per machine by the unique serial number.

                                                                      The customer receives a monthly report of all works executed within the contract and an evaluation is made every 6 months.

                                                                      Result: Cost reduction & increased availability

The number of planned activities (RM) has increased thanks to the preventive and predictive inspections (PM).

                                                                      Maintenance Partners Best Practice Pumps Evolution of costs per quarter

                                                                        Antwerp, November 16, 2015 – Maintenance Partners, the market leader in the Benelux for engineered services and maintenance, repair and overhaul of electrical or mechanical rotating machines, transformers and wind turbines announces to continue its business operations as an independent company. After a successful reorganization under the wings of Mitsubishi Hitachi Power Systems the Belgian management takes over Maintenance Partners through a management buy-out.

                                                                        With mutual respect both companies have extensively been discussing their future business strategies in recent months. Both management teams came to the agreement that Mitsubishi Hitachi Power Systems (MHPS) and Maintenance Partners have the expertise and market opportunities to successfully build a future for their respective businesses without the condition to operate under the same umbrella. The Belgian management will acquire Maintenance Partners for 100% through a management buy-out procedure.

                                                                        Both companies will continue to work closely together in the future as Maintenance Partners remains a partner of MHPS in Europe.

                                                                        The management team and all the employees of Maintenance Partners would like to thank Mitsubishi Hitachi Power Systems for the business dedication the Japanese company has given to its now former Belgian daughter since 2009.

                                                                        About Maintenance Partners
