Oslo headquartered ocean services provider DeepOcean has received a firm order for German based electricity producer RWE’s Nordseecluster A offshore wind project in Germany.
DeepOcean’s scope of work for this new contract includes trenching, transport and installation of all inter-array cables with adjacent services for all wind turbines of Nordseecluster A.
RWE has recently made the final investment decision for its entire Nordseecluster, involving offshore wind projects with a total capacity of 1.6 gigawatts (GW).
The Nordseecluster will be constructed in two phases – Nordseecluster A and Nordseecluster B, whilst the wind farms will be built in the German North Sea, about 50 kilometres north of the island of Juist.
In August last year, RWE announced that DeepOcean had been chosen as its preferred supplier of subsea installation services for the Nordseecluster A.
DeepOcean has now been awarded a firm order that will include preparatory work, transport and installations of all inter-array cables, including trenching, topside pull-ins and terminations for the initial build-out phase.
In total, DeepOcean will install 185 kilometres of 66kV aluminium and copper cables to connect all 44 offshore wind turbines of Nordseecluster A.
Nordseecluster A has a total capacity of 660 MW with the construction at sea scheduled to begin next year, and by the beginning of 2027 all wind turbines shall be connected to the grid.
The second phase, Nordseecluster B, will add a further 900 MW of capacity, with commercial operation expected to begin in early 2029.
DeepOcean’s scope of work also includes project management and engineering; offshore preparation work including pre-installation cable route survey, route engineering and burial assessment, boulder relocation, foundation preparatory work and offshore substation preparatory work; transport and installation of inter-array cables including burial, pull-in, monitoring and testing; as well as seabed surveys and monitoring.
Project management will be based out of Aberdeen, with support functions provided across DeepOcean’s UK and Norway offices.
DeepOcean’s offshore preparations and pre-installation surveys will commence in Q2 2025, with the main works commencing in the beginning of 2026.
DeepOcean informs that it will utilize three vessels for the awarded RWE Nordseecluster A project.
