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 2020: 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 compex 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.

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. We supply blades, shafts, rotor discs, single impellers as spare parts, but also completely assembled rotors.

Our spare parts are manufactured according to the most stringent standards and are 100% compatible. We combine the highest standards of turbo machinery knowledge with an in-depth understanding of material specifications, manufacturing standards and tolerances:

  • Fast delivery
  • Inhouse engineering
  • Inhouse manufacturing
  • Inhouse high speed balancing
  • Onsite installation & commissioning

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

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
  • Process gas: tail gas nitric acid plant
  • Power: 9843 kW
  • RPM: 6600
  • Rotor lay-out: 4 opposed flow (8 rows in total)
  • Mass flow: 27900 kg/h
  • Inlet conditions: 7,1 BARa / 675°C
  • Exhaust conditions: 1,05 BARa / 350°C
  • Year: 1965

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

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.

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
  • Stator Voltage: 10 500 V
  • Output: 15 MVA
  • 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.

Borealis awards MP ‘’Diplôme d’Excellence HSE’’ for works executed during major shutdown

After evaluating the major shutdown in one of its French plants, Borealis has awarded Maintenance Parthers the ‘’Diplôme d’Excellence HSE’’ for taking actions in the areas of health, safety and environment.

Maintenance Partners - Diplome Excellence HSE
Maintenance Partners – Diplome Excellence HSE

Diplôme d’Excellence HSE

The ‘’Diplôme d’Excellence HSE’’ is awarded by Borealis to the top three contractors that have performed the best in QSHE terms. Safety, health and environment are the highest priority for Borealis and suppliers are expected to comply with the highest demands.

By obtaining this award, Maintenance Partners’ employees show that QSHE is a major priority. Moreover, this is acknowledged by one of Europe’s largest chemical companies.

Works executed by Maintenance Partners

During the 3 month Grand Arrêt of the entire plant, Maintenance Partners dispatched 15 specialists on average, including supervisors, technicians, mechanics and project managers. Maintenance Partners was contracted for the major and minor overhauls of the turbomachines that are part of the plant’s nitric acid and ammonia trains. These trains are critical to the customer’s production process and consists of multiple steam turbines, compressors and expanders.

Engineered Services: Re-engineering increases Recip Compressor Lifetime

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:

Coating of rotor

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

250kW Booster fan becomes optional

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.

 

Result for customer: Significant Production Increase

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:

PARAMETERS UNITS BEFORE MODIFICATION AFTER AFTER MODIFICATION INCREASE
RUNNING SPEED RPM 5250 5250
INLET TEMPERATURE 22 22
DISCHARGE FLOW m3/h 89.134 95.700 7,36%

As shown in the table above, the modification has allowed our customer to increase production significantly without altering the operating parameters of the compressor or its driver. In addition, our customer was even able to reduce energy consumption as the booster fan is not required anymore.

Needless to say, our customer is very happy with the results, as the maintenance manager’s quote shows:

“We are grateful for your improvements to our compressor which is of great interest to us”

Moreover, there is room left for further improvement to the compressor, as the current discharge flow increase was achieved without altering the blade carriers.

Maintenance, Rewinding & Complete Renewal of LDPE autoclave reactor motors

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.

Harsh conditionsMaintenance Partners - LPDE Autoclave Reactor Motor - Before Repair

 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.

 

Services MP – From Preventive & Curative maintenance to complete renewal

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.

Engineered Services – Improved Reliability & Durability

A repair is the perfect moment for improvements to the motor, we do so by applying high quality materials, improving designs and evaluating the functionality within the process.

Our Engineered Services vision is based on the idea that maintenance and reliability solutions for rotating equipment are the foundation for improving reliability, output and efficiency of the production process.

Depending on the product and process, the most fitting materials and components for the application are selected by our in-house Engineering department in agreement with the customer. This results in a tailor made maintenance approach that is aimed to improve the reliability and durability of the equipment within the customer’s specific process.

Testing of Roots Blowers and Vacuum Boosters

To ensure reliable functionality after repair, Roots Blowers and High Vacuum Boosters (HVB) are tested in MP’s test facility before shipping.

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!

Inhouse Impeller Design and Manufacturing

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

The quality of singe impellers is checked by a spin test and non destructive testing (NDT).

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.

12-day Pit Stop Overhaul of Thermodyn Steam Turbine, Gearbox & Generator

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

Result – Innovation Plan

Thanks to the 12-day pit stop overhaul, our customer’s production losses were kept to a minimum. The customer was very satisfied with the works performed and has awarded MP a technical call out agreement for future interventions.

To improve the steam turbine’s reliability, the customer and MP are cooperatively working on an innovation plan for the availability improvement of the Thermodyn steam turbine.

In order to achieve the improvements, Maintenance Partners will use its Engineered Services to evaluate all aspects of the machine and determine were improvements can be made.

Best Practice Pumps: Cost reduction & Availability increase

Maintenance Partners does not only apply Engineered Services to compressors, generators and turbines, but also to other rotating machines such as pumps and motors.

Here we give a working example from a customer with a pump population of 200 units:

The improvements have been realised within a contract in which maintenance activities & tasks have been defined and rates have been agreed for standard overhauls. The contract concerns 200 centrifugal 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 also apply.

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

All reporting and communication concerning the pump units is done via MP’s Customer Portal. This is a cloud application that offers solutions for:

  • Sharing large files and documents
  • Centralising reporting & administration
  • Reports and files immediately available for all parties
  • Ensure that latest versions are always available

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 

At the end of the second year, the result of our approach to pump maintenance is clear. The availability of the pump population has increased considerably.

The number of cases of unplanned curative maintenance has reduced from 13 at the beginning of the contract to 2 at the end of year 2:

Maintenance Partners Best Practice Pumps Evolution curative maintenance cases

Simultaneously, the maintenance costs have been reduced by 50% and the share of curative maintenance (CM – unplanned shutdown) has been 1/3 of the original maintenance costs. 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

 

To increase reliability certain design improvements (IM) have been applied. Improvements include upgrading of mechanical seals from single to double versions, improvements to seal surface materials and other material upgrades.

Flashback: Rewinding of second 120MW turbo generator rotor

Two years ago, a 120MW Westinghouse turbo generator rotor was transported by an Antonov An-124 cargo plane from India to Belgium. A high level project that showed Maintenance Partners’ expertise and competences in electrical repairs. Our customer was very satisfied with the works performed and has now sent a second rotor for rewinding.

Flashback to 2013

120 MW turbogenerator rotor 2013 A

On Tuesday November 19 at 11h03, the Antonov An-124 landed at Brussels Airport. The Ukrainian cargo plane carried the cargo of 47.300 kg (rotor including its canister) from India to Belgium. Transportation by plane was chosen because of the urgent need for repair.

After unloading and customs clearance, the rotor was immediately transported to the Maintenance Partners workshop in Zwijndrecht for repairs.

Today

Today, Maintenance Partners is rewinding the rotor’s sibling in its Zwijndrecht workshop. The rotor’s dimensions and output are exactly the same as the previous one. However, this time, the rotor transported by ship instead of an Antonov cargo plane.

120 MW turbogenerator rotor 2015 A

The rotor is part of a power plant in the Middle East that operates three gas turbine driven Westinghouse generators with an output of 120MW each. Since the generators have been running for nearly four decades, wear and tear is starting to occur. In this particular rotor the risk of short-circuits is increasing day by day as the material degrades.

Although temporary repairs can be applied to prevent issues, a full rewind is the only solution that really extends the lifetime and avoids all risks that may occur.

Large project

Needless to say, fully rewinding a rotor that measures 9 meters in length and weighs 38 tons is a job of considerable size. A team of up to 8 electrical specialists will work round the clock to ensure delivery of the rotor by end of 2015.

Improvements

During the rewinding of the rotor, improvements will be applied to improve durability. For example new antimagnetic retaining rings will be fitted to avoid oxidization and pitting that eventually leads to micro cracks.

Besides this, the insulation will also be upgraded from mica based material to nomex based material. This type of insulation is more durable and has a longer expected lifetime than traditional mica based insulation.

Stator Repairs

When the rotor is rewound and shipped to the Middle East, onsite repair works on the generator stator will begin. The goal of these repairs is to extend the stator’s lifetime and postpone rewinding of the stator.

Engineered Services: Steam Turbine Rebuilt after Fire

After a fire at a specialty chemicals manufacturer, Maintenance Partners was asked to inspect, repair and commission the steam turbine and generator within 6 months. Read the full story below:

Specialty Chemicals Manufacturer

Our client is a manufacturer of a specialty chemicals and performance materials that specializes in the production of carbon black. Carbon black has many applications, ranging from pigment in coatings, inks and plastics to the enhancement of materials to be more conductive or UV-resistant.

Energy Recuperation

In the client’s manufacturing process, gas is generated as a byproduct. The gas is used by a boiler to generate steam that drives the steam turbine which powers a generator. By doing so, a significant amount of electricity is produced using waste gas. This reduces the client’s ecological footprint and lowers the costs of energy that are required to operate the facility.

Catastrophic Failure

Due to a malfunction in the generator’s control system, the generator started to drive the steam turbine (instead of the steam turbine driving the generator). This caused the steam turbine to vibrate excessively and to leak oil. The combination of oil and high temperatures led to a fire in the powerhouse building, resulting in severe damage to the entire turbine generator train and its auxiliaries:

Inspection

Immediately after the fire, Maintenance Partners was asked to inspect the entire turbine-generator train in a short time frame. The goal of the inspection was to determine if repair was a possible option.

Severe damage to the steam turbine

The inspection showed that the coupling had absorbed most of the vibrations when the breakdown occurred. This left the gearbox and generator relatively undamaged. However, the steam turbine was severely damaged:

Diaphragms

  • Cracked welds
  • Bent vanes
  • Nozzles completely torn off & bent

Casing

  • Deformation of casing (combination of heat, vibration and damage to rigidity pillars)
  • Cracks
  • Damage on all diaphragm places, bearing places and all oil seal places caused by vibration

Valve bodies

  • Heavy damage
  • 1 valve broken off
  • Nozzle buckets bent

Rotor

  • All blades significantly damaged – stage 7 partly torn off and stage 6 completely torn off
  • Heavy damage to bearing journals
  • Heavy damage to seals
  • Rotor was bent (up to 0,2mm)

 

Renewal vs Repair

Awaiting the outcome of the inspection, our client considered ordering a new steam turbine. However, delivery, installation and commissioning a new steam turbine was estimated to take up to 2 years.

Maintenance Partners’ repair proposal offered a solution in which the steam turbine would be running within 6 months. A downtime of another two years was unacceptable, so Maintenance Partners was awarded the contract for the repair. The repair works began in January.

Repair | Steam Turbine

To ensure that the steam turbine would operate again, Maintenance Partners had to completely redesign, rebuild and re-align major components:

Rotor

  • Full rotor reblade
    • Complete re-engineering of the 6th row turbine blades
    • Reverse engineering of all other blades
    • Upgrading of material specifications to be more durable
  • Straightening of rotor
  • Repairing the bearing journals and seal places
    • Machining off the damage
    • Laser cladding by Maintenance Partners’ welding robot
    • Machining
  • Re-engineering the steam seals & completely redesigning the steam sealing system
  • Applying special coating on rotor surface in order to prevent corrosion and extend the rotor’s durability

Casing

  • Straightening
  • Repairing of cracks
  • Machining the damaged parts of the casing

Diaphragms

  • Rewelding the cracked welds
  • Straightening the vanes
  • Realigning the vanes in the casing

Redesigning of safety systems

  • Replacing of manual hydraulic extraction actuation system with an electronic system

Repair | Generator & Gearbox

Although the generator and gearbox had only sustained minimal damage,  both machines were cleaned and overhauled to ensure safe and reliable operations.

Repair | Auxiliary pumps and motors

The fire had also damaged the steam turbine’s auxiliary pumps and motors (5 oil pumps, 3 AC motors and 1 DC Motor). The 2 control oil pumps, bearing oil pump and emergency oil pump were overhauled and the DC motor had to be rewound. All AC motors were replaced by new ones.

Onsite Rebuild & Startup

All repair works were Maintenance Partners Steam Turbine Rebuilt after fire 00acompleted in May and one of our specialized field service teams started rebuilding the steam turbine and generator. The team’s activities included:

  • Realigning entire turbine generator train
  • Regrouting the generator and exciter
  • Renewal of  all the probes and sensors
  • Installation of an online monitoring system in the generator
  • Reprogramming the safety trips on the turbine
  • Replacing the hydraulic actuator with an electronic system
  • Realigning the rotor in the casing

Finally, the steam turbine was started up on July 16.

Result for Customer: Steam Turbine running better than before

Our customer experienced an increase in efficiency compared to operating data from before the crash:

  • Steam leakages fully resolved
  • Vibration
  • Less temperature losses
  • Better vacuum pressure

In conclusion, the repairs and improvements that the turbine and generator underwent have resulted in a machine that is running better than before the breakdown:
