New MHI forklifts for Maintenance Partners!

Last week the new forklifts were delivered at the Zwijndrecht Workshop. The previous generation forklifts had to be replaced and, with regards to health and environment, our preference was to select new electric powered forklifts.


After an analysis of different alternatives on the market, the best solution could be found in our own group. Mitsubishi Heavy Industries’ forklifts met all our demands and use the latest technologies. Besides this, the MHI forklifts are low maintenance, resulting in more reliable machines than our previous forklifts.

The new forklifts will result in an improvement in terms of safety, health and environment. More info can be found at De Ronde en Drubbel’s website.

Reciprocating Compressor Maintenance from A-Z

Earlier this year we were contacted by a refinery about a failing reciprocating compressor. This reciprocating compressor is a critical part of customer’s production process, so every unplanned shutdown leads to losses in production.

Zuigercompressor 590


Maintenance Partners proposed to perform an audit on the reciprocating compressor to determine the cause of failing. During these audits, vibration measurements, visual inspections and checks of the compressor’s foundation are performed. Besides this, the maintenance planning, technical data and use of wearable parts are reviewed. These comprehensive compressor audits allow us to draw up the compressor’s condition and propose potential solutions.

The audit showed that an overhaul of the reciprocating compressor was necessary to prevent wear of  moving parts and auxiliaries would lead to an unplanned shutdown. Additionally, it was advised to renew the compressor’s foundation.

To ensure continuous operation, the customer decided to schedule the overhaul and foundation renewal in this autumn.


Urgent overhaul: Back in operation after 28 days

A regular check after the audit showed that the maximum allowed vibrations were exceeded, caused by a failing foundation. Action on short notice was required to prevent a breakdown of the reciprocating compressor. The scheduled overhaul was performed 4 months earlier than originally planned. Within a month, the major overhaul and foundation renewal were completed and the reciprocating compressor was back in operation after 28 days.


Extension of Maintenance Intervals

Meanwhile, possibilities are evaluated to extend the time between maintenance intervals from 8000 running hours to 16000 running hours. This extension can be achieved by upgrading wearable parts, adjusting filter systems and installing condition monitoring equipment. For the customer, this means that the reciprocating compressor can be kept in operation longer, resulting directly in increased production.


One-stop-shop for reciprocating compressor maintenance

This case shows that Maintenance Partners can offer total solutions for reciprocating compressor maintenance, from performing audits to full overhauls and proposals for reliability improvement. Besides overhauls, field works and audits you can also contact us for foundation renewals, diagnostic maintenance, condition monitoring and spare parts. Our services are not limited to a single brand or make, we can work on any brand of reciprocating compressor.

Spare Parts

It is often difficult to find the right spare parts for reciprocating compressors. Moreover, finding spare parts gets more difficult as the equipment gets older. In many cases, the original parts can not be delivered within the required planning.

A solution for this problem can be offered by re-engineering, in addition this can also allow for improvements to the original part. In our engineering department, we have combined all the necessary knowledge and expertise to perform projects like these completely, from drawing to part manufacturing. This allows us to deliver spare parts with shorter lead times and a high quality.

    Engineering: 12MW motor like new

    MP builds complete 12MW stator12MW Stator Maintenance Partners

    Maintenance Partners shows its engineering capabilities by building a new stator for a motor that drives a hyper compressor at Sabic’s plant in Geleen (Netherlands). Frank Claus, Technical manager – engineering department, who followed up the project technically and commercially: ”In Sabic’s production process a hyper compressor is used with a pressure of >2000 bar.

    The project concerns a synchronous motor that is DC powered and runs at 187,5 RPM constantly. Measurements one year prior to the stator swap showed that the rotor was still in good condition, but the stator proved to be in very poor condition. ”We got the order to build and install a new stator”, says Frank.


    10 months from engineering to realisation

    In 10 months time a completely new stator was built from engineering to realisation by an extensive team. During the rewinding, the the new stator was built. The works were supervised by the Dutch KEMA-DEKRA.

    ”This concerned a motor with an Ex n certification, a ‘non-sparking motor’. KEMA could provide the Ex n certification, because the new stator is fully compliant with the orinial specifications.  An absolute must to get the job”.


    Reverse engineering

    The winding of the stator required one of Maintenance Partners’ specialties: reversed engineering. ”There were original drawings, says Frank, ”but there was no data available on the windings. During a shutdown to extend the motor’s lifetime, we recorded all the necessary data.”

    The transport to Sabic’s facilities in Geleen proved to be a challenge, due to the large external dimensions: 6.30m tall, 5.20m wide and a depth of 1.5m. During a planned shutdown, the stator was loaded and transported to Sabic.

    Spectacular installation

    Maintenance Partners had 14 days to install the new stator. During the installation, a group of 7 worked in two shifts around the clock. The rotor and the existing stator (combined weight of 65-70T) had to be lifted simultaneously. After this, the old stator had to be replaced by the new one and everything had to be assembled. A special lifting plan was drawn up, because the roof had to be removed before the machine could be lifted.

    During the installation of the new stator, the team noticed that the motor’s exciter was in bad condition. Because the exciter is essential for the motor to run, the decision was made to rewind the exciter in the Zwijndrecht workshop during the shutdown.

    Despite this unforeseen problem, the exciter rotor was rewound within a week without delaying the original installation planning of the project.


    Energy Savings

    Measurements conducted by Sabic show that the new stator’s power consumption is reduced by 450kW per hour at full load. The energy savings were realised by using the best available materials and by an improved stacking of the magnetic stator core. This has increased the density of the core, resulting in improved efficiency.


    Team Effort

    The project went really smoothly thanks to the good cooperation between the teams that worked on the stator. Completing projects like these shows that MP has the necessary engineering knowledge and expertise to peform overhauls on critical equipment and even apply improvements.


    Cooperation with Sabic

    ”This was a very nice project, mainly due to the pleasant and intensive cooperation with the people at Sabic. We were able to use our experience from previous projects (MP overhauled a hypercompressor motor at Sabic before and built two generators at the Swedish paper manufacturer Smurfit Kappa). Moreover, we have gained more experience by completing this project. Experience we’ll certainly use in the future, because there clearly is a demand in the market for interventions like these”, concludes Frank.

      Maintenance Contracts for Wind Turbines & Performance Optimization

      Wind Field ServiceIn cooperation with seebaWIND Service, Maintenance Partners offers LTSA maintenance contracts for wind turbines. These contracts are based on availability guarantees and performance improvements.

      ‘’The Premium Plus service contracts offer optimal LTSA maintenance to the German market’’ explains seebaWIND Service CEO Severin Mielimonka. ‘’Run to failure belongs to the past as Premium Plus allows complete predictive maintenance’’.

      Maintenance Partners’ WINTELL intelligent data management system links all production, reliability and weather data and makes early prediction of disorders, failures and performance deviations possible. “With the help of WINTELL we can increase yields, improve the availability of the wind turbines and allow operation over the 20 years to come” says Mielimonka.

      SeebaWIND Service handles the 24/7 monitoring of the wind turbines via their remote control center. On top they take care of preventive and corrective maintenance including spare parts. Maintenance Partners is taking care of all main components, covers machine breakdown, wear and tear and business interruption costs. Both companies create added value by utilizing the Wintell system and in-depth analysis of historical data of the windturbine controller.


      Long-term revenue optimization

      The first joint Maintenance Partners-seebaWIND Service Premium Plus project in Germany has been launched on April 1 2014 in Neuengörs in Schleswig-Holstein.

      The wind farm that was commissioned in 2001 consists of six turbines of type Senvion MD70 (formerly REpower ) with a total of nine megawatts. All wind turbines have been upgraded with the WINTELL data management system. Through real-time data access, all data supplied by WINTELL will be monitored accurately.

      The second step in the project is the optimization of systems to improve efficiency. In this phase seebaWIND service plans a site-specific optimization of systems to improve efficiency. “The Premium Plus LTSA maintenance contract by seebaWIND Service and Maintenance Partners has given us the new approach that convinces with a very transparent and predictive maintenance” says Joachim Fröhlich from Denker und Wulf AG, the company that takes care of the wind farm’s technical operation. “The concept is to operate the plants as long as possible.”

      Maintenance Partners and seebaWIND Service have cooperated for projects in other European countries, including France and Spain, since 2013. “With seebaWIND service, we have found a partner that is service-oriented, responds quickly, solves problems, and has the necessary technical competence” says Pascal Collin, Business Development Manager at Maintenance Partners’ Wind Department.

      Revision and rewinding of high voltage motors

      Maintenance Partners has decades of experience with the maintenance and rewinding of high voltage motors. The work for high voltage motors can be divided into onsite inspections and workshop repairs.


      Onsite inspections

      The first inspections for high voltage motors are usually carried out on site. Dismantling the high voltage motor is usually not necessary, because we can make a “technical snapshot” using endoscopy or non-destructive material testing. The motor’s isolation value motor is determined by high voltage measurements such as DLA-measurements and Partial Discharge (PD or partial discharge) measurements. These measurements result show a clear picture of the motor’s condition and offer an indication of the remaining lifetime.

      An extensive inspection can be carried out if more detailed information is required about the condition of the motor. For these extensive inspections, end-plates need to be removed to allow for elaborate electrical measurements and mechanical inspections. As part of an extensive inspection, we also perform small repairs on the windings and isolation of both the rotor and stator.

      Online Monitoring

      Apart from onsite inspections, Maintenance Partners also offers the option to monitor the condition of the motor while it is in operation by using online monitoring. The advantage of online monitoring is, that the motor will be measured 24 hours a day and that we can intervene if necessary.

      Repairs in the workshop

      If the inspections show that the operational reliability of the high voltage motor can no longer be guaranteed, an on site inspection is not enough.

      During a standard revision, the motor is be cleaned and dismantled. In addition, all seals and bearings are replaced.

      Rewinding of high voltage motors

      In case of severe aging or damage to the windings, the only solution is to rewind the motor in most cases. The lead time for rewinding high voltage motors is often shorter than the delivery time for a replacement motor. Before we can start winding the high voltage motors, the coils have to be completely measured and reverse engineered.

      Apart from winding high voltage motors in the workshop, we can also take care of the revision and replacement of laminated cores. By using the latest materials, our engineering department can improve the efficiency and life expectancy of the high voltage motor.

      When the winding is finished, the motor is assembled and the mechanical and electrical aspects are checked in detail. At this stage, ultrasonic and ELCID tests are used.

      Winding of a 12 Megawatt stator

      An example of one of our projects is the winding of a 12 Megawatt stator for a Dutch customer. For more information about this project we recommend reading the article on our website.

        Special Delivery: Antonov An-124 Transports 120MW Generator Rotor

        Tuesday November 19 is a memorable day for two companies in the port of Antwerp. Maintenance Partners and Silvertrans have joined forces to transport a turbogenerator rotor with an Antonov An-124 cargo plane from India to Belgium.

        Antonov - Turbogenerator - Maintenance Partners 001a






        The rotor is part of a 120MW Westinghouse generator that is being used for power generation in the Middle East. The generator is driven by a gas turbine. With a length of 9 meters and a weight of 38 tonnes, it is a rotor of considerable size.

        On Tuesday November 19 at 11h03, the Antonov An-124 landed at Brussels Airport. After unloading and customs clearance, the rotor was immediately transported to the Maintenance Partners workshop in Zwijndrecht for repairs.

        The Ukrainian cargo plane Antonov An-124 carried the cargo of 47.300 kg (rotor including its canister) from India to Belgium. This plane has been chartered, because the rotor is damaged and the generator rotor is essential for power generation.

        Rotor Repair: 75 days, 24/7

        The Zwijndrecht workshop has the specific compentences, required to successfully complete such complex electro technical projects.

        After the rotor has been delivered to the Zwijndrecht workshop, a team of specialists and engineers will work for 75 days and 7 days a week on the rotor. On average, 5 to 6 people are working continuously on the rotor during the project. During the project, the rotor’s insulation system is repaired. After this, the rotor will also be balanced at high speed.

        Unique Project

        For Maintenance Partners, this is a unique project that allows us to show our expertise and compentences in electrical repairs. The transport is not just unique for Maintenance Partners, but also for our partner Silvertrans and the Zaventem airport. We have cooperated with a company nearby, allowing for a smooth cooperation between both companies.


        News items & Interviews

        The Belgian media have also covered the rotor’s transport. Articles and news items have been published by different media, including Kanaal-Z, Het Laatste Nieuws en de Standaard.Silvertrans has released a series of photos showing the transport.

        Winding of large critical stator started

        On Friday November 15, a very large stator was delivered in our Zwijndrecht workshop. This delivery is the beginning of building a 12 MW electro motor that drives a critical hypercompressor at one of our customers in The Netherlands. With a width of 6.3 meters and a height of 5.2 meters, this is a motor of considerable dimensions and unique specifications:

        Type Alternating Current
        Power 12 megawatts
        Voltage 10 kilovolt
        Speed 32 pole / 188 rpm
        Protection Ex (non sparking)

        Partial Discharge in Existing Stator

        The existing stator is replaced, because measurements have detected partial discharges. Partial Discharges are a sign of wear or aging of the insulation and can lead to ozone emissions. The ozone emissions are a potential hazard for the working environment. Moreover, ozone is a highly aggressive gas that affects the insulation material and speeds up the aging process of the material.



        The driven hypercompressor is a critical machine and is necessary for the customer’s production. Because the hypercompressor is highly critical, the customer has decided to build a new stator with the exact same dimensions and specifications. The new stator will replace the existing stator in order to reduce production downtime as much as possible.


        Stator built according to Ex specifications

        In the next months, the stator will be finished. This mainly consists fo winding the stator and applying the insulation. Because the motor is installed in an hazardous environment, the stator will be built according to Ex specifications. To ensure the protection of the motor, DEKRA (the former Kema) will follow up the process to assess if the motor is built according to Ex specifications.

        In the first quarter of 2014, the motor will be transported to the customers’ production facility. The stator will be placed, after which the rotor is installed and the motor is commisioned. After commissioning, the motor can run reliably and safely for years.

        First IECEx-03 certified workshop in Belgium

        As of August 13 2013, Maintenance Partners Belgium has obtained IECEx-03 certification for repairs of electrical and mechanical Ex rotating equipment.  Big news, as Maintenance Partners Belgium is the first company in Belgium to obtain the IECEx-03 certifcate.

         The MP The Netherlands workshop Rotterdam has been IECEx-03 certified since 2011.


        IECEx-03, what does it mean?

        Ex environments are usually located near flammable fluids, vapers gasses or flammable dust in quantities that are sufficient to cause a fire or explosion. In these environments, the use of Ex equipment is necessary to ensure safe operations.

        During the certification process, the Zwijndrecht workshop was audited on the competences of employees and the workshop. In addition, internal and external audits regularly monitor the follow op of the IECEx-03 standard.

        By obtaining this certification, the Zwijndrecht workshop has become an IECEx-03 Certified Service Facility. This means that all types of rotating equipment (electrical and mechanical, regardless of make or brand) can be maintained, overhauled or repaired according to strict regulations and in a safe way. Besides this, the IECEx-03 certificate is also valid for works on site at our customers.

        Protection Methods

        The IECEx-03 certificate allows Maintenance Partners to repair equipment that has been certified according to the following protection methods

        • Ex e       Increased Safety
        • Ex d       Flameproof Enclosure
        • nA          Non Sparking
        • Ex c        Constructional safety
        • Ex b       Monitoring of ignition sources
        • Ex fr       Limitation of flow (gas-tight enclosure)
        • Ex k        Liquid immersion
        • Ex p       Pressure
        • Ex tD     Protection by enclosure
        Repairs of Ex equipment? The IECEx-03 standard ensures maintenance is performed according to strict standards. Electrical as well as Mechanical Ex equipment.

        Where can Ex equipment be found?

        Ex equipment can be found in many industries, including the following:

        • Gas distribution
        • Sugar
        • Wastewater and sludge treatment
        • Offshore platforms
        • Oil refineries
        • Chemistry
        • Grain and coal handling
        • Energy

        Why IECEx-03?

        The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety. The IECEx-03 standard has been developed because users of ATEX equipment should prove that maintenance is performed by competent personnel.

        For LV and HV electrical motors and generators, Maintenance Partners Belgium is already certified by ISSEP and ABB. The ISSEP certification is valid in Belgium and the ABB certificate is valid for equipment manufactured by ABB. Besides this, there are also a number of differences between ATEX and IECEx (for example, regulated by industry, certified workshops, valid outside Europe).

        The IECEx-03 certifcate is an internationally recognized standard and is not limited to any type of equipment or brand. As a result, the existing certifications for explosive environments are complemented, this expands the range of Maintenance Partners’ services on Ex equipment.

        Certainty & Safety

        The IECEx-03 standard for Certified Service Facilities provides users of ATEX equipment the certainty that maintenance is always carried out according to the standard and by competent personnel. The safety of the equipment is therefore also ensured after repair.

          Replacing a generator in a 110 meter tall wind turbine?

          Replacing a generator in a 110 meter tall wind turbine? MP wind has what it takes to do it. It happened in St Pierre de Maille, France. Olivier Dewez tells the story.

          Precision work at 110 meters

          Olivier Dewez: “We have a long-term service contract with a five wind turbines wind farm in the region of Charentes in France. A 2.5 MW Siemens Winergy generator appeared to have suffered some damage to the rotor and stator. One little problem: that wind turbine is 110 m tall! We had to dismount the damaged generator and replace it with a new one – all of that in very difficult circumstances, given the very narrow opening in the wind turbine nacelle and the weight of 9.5 tonnes of the generator.“ The team of MP Wind did the job in two days, a day for dismantling the existing generator and installation of the new one and one day to connect it and do the testing.


          Experience and expertise in the wind energy sector

          That MP Wind was able to do this job successfully and so quickly, has everything to do with our extensive experience in repair and overhaul of generators. This enables MP Wind to offer a total service package for generators. This package includes both Field Service (General inspections, Diagnosis and Revisions) and Repair & Maintenance (rewinding, stators and rotors, re-engineering).

          Ready for the future

          “With this job Maintenance Partners once again proves that it is ready for the future in the field of services to the wind energy sector. The technical tour de force in France gave us extra experience and knowledge on turnkey services to major components, which adds up to the preventive and corrective services we are already offering. Overall, it has been a great experience for our team, especially the cooperation with French colleagues and partners. And very encouraging for the future wind energy business of Maintenance Partners”, Oliver Dewez concludes.

          Complicated Pump Repair

          Maintenance Partners The Netherlands recently overhauled a large pump at a refinery in the Netherlands, resulting in a satisfied customer.

          In competition with several OEMs, MPNL was asked to bid on the revision of an Ingersoll Rand pump, Type 6x16JL.  “We made it, despite stiff competition, thanks to our price, flexibility and proven quality. It was no small deal, because the pump was severely damaged.”

          Complicated repairs

          After disassembly and inspection of the pump it showed that the impeller had completely seized in the pump over. MPNL decided to saw up the pump shaft and to remove the impeller completely from the pump in order to minimize further damage tothe pump cover. But NDT examination of the pump cover pointed out that the heart of the cover was torn in several places.

          “To fix this, we proposed that the heart of the pump cover be completely milled out. After we had determined which materials we should use, we manufactured a completely new (oversized) insert, mounted it in the milled out pump cover and welded it. After that the insert was machined entirely in in the right sizes, in  accordance with the drawing. “

          Creativity, flexibility and quality

          The MPNL team also made a new shaft and sleeves. This way, they could assemble the spare impeller that the customer had supplied , after which the pump was mounted in overtime. Because the customer wanted to equip the pump with double mechanical seals, the seal chambers were modified.

          After placement on site, MPNL assisted in thestart-up and commissioning of the pump. That went smoothly. “Following this overhaul, we have received many compliments from employees and from the project team.

          Our trumps, such as flexibility, inventiveness and quality of the work performed, were highlighted”. “All in all, the customer has realized substantial time and cost savings realized by having the pump cover repaired instead of replaced, which undoubtedly would have been more expensive and would have taken more time”.

          Successful relocation of two Stal Laval steam turbines

          Maintenance Partners Stal LavalWith the successful relocation of two Stal Laval steam turbines Maintenance Partners has not only acquired a wealth of experience. We have also proven that we are running a well-oiled machine in which engineering, workshop, field team and lots of talent are working together perfectly.

          The customer recuperated two radial Stal Laval steam turbines, each coupled to 2 generators with a total capacity of 9 MW. Maintenance Partners was asked to re-install the units in the new building in the Walloon region.

           “As in any industry, this customer is trying to be as selfsupporting as possible with regard to its energy needs. From their production process, they recover much energy that can be used to provide additional steam. So, the steam turbines from the closed factory came in handy.”

          Experience for the future

          Early this year, MP started dismantling the two Stal Laval steam turbines. After inspection, overhaul and repair of all parts, everything was transported to the new location early March. Early May, work at the new building had sufficiently proceeded as to begin with the installation of the turbines. Early September, they could start up both turbines at the new location.

          ‘’This job yields a wealth of experience with the relocation of Stal Laval turbines. We already had the necessary experience with the overhaul and rewinding of such machines, but a relocation always brings up extra issues. Among other things, the axial and radial alignment of both rotor combinations is very critical, given that they run together with only a few tenths of clearance, and a speed difference of 6000 rev/min. With this experience, we completed a large piece of the puzzle with regard to Stal Laval steam turbine generators. This should enable us to meet every demand associated with this type of machine. “

          Control of process

          Moreover, this job proves that the various departments of MP, each with their own skills, are working together perfectly. Engineering did all the preparations and studies, and offered support to the workshop and on-site. All preparation work was done in the perfectly equipped workshop, offering all the necessary skills. And for the work on-site MP could count on a highly experienced field team. “This means that we can do everything ourselves from start to finish, so we have full control over all operations. This is vital when working on critical machinery, since the slightest mistake may have disastrous consequences. In this domain we are all geared up for the future “
