Recent project: repowering of 9 windturbine gearboxes 

Project Description  

Stork Gears & Services was in charge of repowering the windturbine gearboxes as part of the MEPscheme*. According to the MEP scheme, gearboxes must be restored to their original specifications within a fixed timeline. Due to our technical expertise plus our first class inhouse repair facilities we were able to provide complete repair services to our customer, instead of replacement of the damaged bearings, gears and shaft. The project was executed within a tight time schedule, in which the various overhaul activities had to be carried out very closely together. 


  • Complete gearbox overhaul of 9 windturbines
  • Shaft wear protection by lasercladding
  • Regrinding of the gears
  • Testing and assembly of the gearbox


* The MEP Scheme (Milieukwaliteit Energie Productieregeling) is aimed at the cost-effective promotion of environmentally responsible generation in the Netherlands.
