Wind turbine gearbox repair

The gearbox in a wind turbine is a main part which need constant attention. If you have observed that the wind turbine gearbox not works properly, and need to be repaired, we are ready in our workshop to make a 100% quality and cost benefit repair.

We can make an offer based on your demands, an inspection report or make a standard offer (renewing of all bearings and seals) and subsequent make a final offer based on a full inspection of all parts after dismantling.

A standard repair takes only 3 weeks (15 days of work) in our workshop.

Day 7: Failure detection

Day 8-12: Reassembly

ME Production A/S refurbishes wind turbine gearboxes in our modern facilities equipped with overhead cranes providing lifting capacity of up to 35 tonnes. We repair from small gearboxes and up to 3 MW. Our workshop area is divided into seperate areas for the different steps in the repair process:

  1. Complete disassembling
  2. Cleaning of all parts
  3. Failure detection and root cause analysis

Besides the workshop, we also have a seperate machining department, in which we can carry out all types of repairs on shafts and housings. This ensures the fastest possible lead time.

With over 200 repairs on gearboxes for wind turbines and many years of experience in gearbox design, manufacture and service, we have highly skilled gearbox personel. In addition we have engineers and developers in-house, who work with the newest software for designing gearboxes and calculating critical components.

We keep educating our employees in order to follow and make use of the newest methods and technologies. This is secured by participating in different courses and sharing this new knowledge in-house. We have close collaboration with the suppliers in order to stay updated on the newest products and solutions available on the market.
