DeepOcean completes inter-array cable installation at Nordseecluster A


DeepOcean has completed the installation and testing of all inter-array cables at the Nordseecluster A offshore wind farm in Germany.

The company installed 48 inter-array cables linking turbines and offshore infrastructure, with cable-laying operations taking place between January and April 2026. Additionally, termination and testing activities have now been completed.

The installation campaign involved four vessels, including the subsea construction vessels Olympic Ares and M/S Volantis. DeepOcean also carried out seabed surveys and burial operations as part of the project.

Nordseecluster A is the first phase of the wider 1.6GW Nordseecluster development being built by RWE and Norges Bank Investment Management. The project will comprise 44 Vestas V236-15MW turbines and deliver 660MW of installed capacity when commissioned in early 2027.

Completion of the inter-array cable works marks another key construction milestone as the project progresses towards first power.
