By early 2027, all the wind turbines should be connected to the grid
RWE has contracted DeepOcean to support the Nordseecluster A offshore wind project in the German sector of the North Sea.
Constructed in two phases
The development will be constructed in two phases, Nordseecluster A and Nordseecluster B, with a total capacity of 1.6 GW, about 50 km north of the island of Juist.
Last August, RWE designated DeepOcean as its preferred supplier of subsea installation services for Nordseecluster A. The company now has a firm order that covers preparatory work and transport/installation of all inter-array cables, including trenching, topside pull-ins and terminations for the initial build-out phase.
Commercial operations
In total, DeepOcean will install 185 km of 66-kV aluminum and copper cables to connect the 44 offshore wind turbines of Nordseecluster A (total capacity 660 MW).
Construction at sea is due to start next year. By early 2027, all the wind turbines should be connected to the grid. The second phase, Nordseecluster B, adding a further 900 MW of capacity, should start commercial operations in early 2029.
Offshore preparation work
DeepOcean’s work scope extends to project management and engineering; offshore preparation work, including the pre-installation cable route survey, route engineering and burial assessment; boulder relocation, foundation preparatory work and offshore substation preparatory work; transport/installation of inter-array cables including burial, pull-in, monitoring and testing; seabed surveys and monitoring.
The company’s Aberdeen office
The company’s Aberdeen office will manage the program, with support from other offices in the UK and Norway. Offshore preparations and pre-installation surveys are due to start in second-quarter 2025, with the main works getting underway at the start of 2026.DeepOcean will use three vessels for the campaign.
Woodside Energy appoints DeepOcean offshore Senegal
On the other hand Ocean services provider DeepOcean is awarded frame agreements by Woodside Energy (Senegal) B.V. to provide subsea inspection, maintenance, and repair (IMR) services for the Sangomar field located offshore Senegal, West Africa.
Standalone ROV operations.
The Sangomar deepwater oil field is located 100 kilometres south of Dakar, Senegal, and commenced production in June 2024.
The scope of work includes project management, engineering, and execution of subsea services such as inspection, survey, intervention, and maintenance, as well as additional services such as underwater inspection of FPSO (UWILD) and standalone ROV operations.
