Operations & Maintenance

February 28, 2024, by Adnan Memija

Acta Marine’s service operation vessel (SOV) Acta Centaurus will soon commence maintenance work at Vattenfall’s DanTysk and Sandbank offshore wind farms in the German North Sea. The entire service campaign is expected to last until October 2024.

The vessel is currently making a stop in the Port of Hamburg before starting work for Vattenfall’s offshore wind farms in the next eight months.

Acta Centaurus will make its way to the Danish Port of Esbjerg on 29 February where it will be mobilised for several days. There, containers with the technical equipment, tools, and spare parts for the wind turbines will be loaded and the service technicians will go on board.

First, the SOV will work at the Sandbank offshore wind farm for four months and after that, it will carry out maintenance work at the DanTysk project for another four months.

Up to 100 people will work on the maintenance of the wind farms in shifts during peak times over the coming months, said Vattenfall.

Every 14 days, Acta Centaurus will regularly call at Esbjerg to load new equipment and change service teams.

In February 2023, the Netherlands-based Acta Marine won a tender to provide an SOV during operations and maintenance (O&M) at the DanTysk and Sandbank offshore wind farms in Germany.

Under the contract, the company will provide a vessel for the service campaigns in 2024, 2025, and 2026.

Located some 70 kilometres west of the island of Sylt, the 288 MW DanTysk offshore wind farm comprises 80 Siemens Gamesa 3.6 MW turbines that have been in operation since 2014.

Sandbank offshore wind farm has been in operation since 2016. The wind farm also has a 288 MW capacity and its 72 Siemens Gamesa 4 MW turbines are spinning some 90 kilometres west of Sylt.

Both wind farms are owned by Vattenfall (51 per cent) and Stadtwerke München (49 per cent).
