innogy are preparing to carry out heavy maintenance at one of the 56 SWT-6.0-154 turbines at the 353 MW Galloper offshore wind farm. An application for a marine licence was approved earlier this month for a jack-up vessel to be used to replace the generator at turbine GN-D2B.

According to innogy, "the turbine involved has continued and still is, running at maximum capacity, so all is well on that front. The application allows for maintenance work to be carried out when we’re ready, so we’re well prepared.

innogy hope to learn more once they have examined the generator during a planned maintenance visit to be scheduled later this year. innogy has stated that the marine license for the use of a jack-up gives the flexibility and scope to carry out what ever work is required when the time comes.

The license covers the use of a jack up and a hydraulic turning tool to remove the individual blades, one at a time, the nacelle. The generator will then be removed, placed on the jack-up vessel and replaced. Crew Transfer Vessels (CTVs) may also be required to transport technicians and engineers. Work is expected to commence later this year, lasting approximately seven days.

Located in the Outer Thames Estuary, approximately 27km from the Suffolk coast, the wind farm is owned by innogy SE, Siemens Financial Services, Sumitomo Corporation and ESB and a consortium managed by Green Investment Group and Macquarie Infrastructure and Real Assets.

innogy led the project’s development and construction and since 2018 operates the wind farm it on behalf of the project partners. A team of 60 employees operate and maintain the wind farm from a temporary facility in Harwich International Port.

Galloper Wind Farm Ltd recently signed an agreement for the sale of its transmission assets to Diamond Transmission Partners.
