Gamesa Offshore G128-5.0 MW

Gamesa is working on the technological design and development of its G11X-5.0 MW platform which will be equipped with a 128m rotor diameter and a modular and redundant design that will enable partial load operations while guaranteeing reliability and maximising energy production.

The Gamesa G128-5.0 MW offshore wind turbine leverages the proven technology validated by Gamesa in recent years in its G10X-4.5 MW platform and the operating know-how and experience built up.

This proven Gamesa technology, designed and developed for the G10X-4.5 MW platform, includes the CompacTrain®, Gamesa MultiSmart ®, Gamesa FlexiFit® and Gamesa GridMate® technology:

• CompacTrain ®: the drive train consists of a semi-integrated main shaft and a 2-stage gearbox with mid-speed range output. This integrated design makes the unit more compact, with fewer components. The mid-speed range output improves reliability by eliminating high-speed rotating mechanical components, minimising maintenance work.
• Gamesa MultiSmart ®: the wind turbine control system uses the data gathered to regulate each blade individually, moderating vibration and reducing up to 30% of the load on some components. This system incorporates the latest technology based on optimising aerodynamics, control and efficiency all with a view to maximising energy output.
• Gamesa FlexiFit®: the crane, coupled to the nacelle so that it does not require an additional external structure, makes offshore wind farm servicing more flexible and simplifies maintenance and assembly work, replacing the need for certain major parts. Gamesa FlexiFit® eliminates the need to use high-tonnage barge-mounted cranes for maintenance work: once attached to the nacelle, the crane can hoist and lower main nacelle modules (hub, gearbox, generator, transformer, heat exchanger, among others).
• Gamesa GridMate®: redundant electrical system based on a permanent magnet synchronous generator and a full converter. The system comprises parallel modules which continue to function in the event of individual failure while also enabling partial capacity utilisation configurations. Gamesa GridMate® complies with the most demanding grid connection requirements.
