DeepOcean has completed the installation and testing of all inter-array cables at the Nordseecluster A offshore wind farm in Germany. The company’s scope of work included project management and engineering, provision of cable protection systems, offshore preparatory works including burial assessments, pre-installation cable route surveys, foundation and offshore substation preparation, transport and installation of inter-array cables including cable pull-in, as well as cable burial, seabed surveys and monitoring.
Cable-laying operations began in January 2026. A total of 48 inter-array cables were installed between January and April, with termination and testing activities now completed.
DeepOcean deployed a fleet of four vessels for the installation campaign, including its chartered multi-role subsea construction vessel Olympic Ares and subsea construction vessel M/S Volantis, alongside two walk-to-work vessels. Seabed survey services were carried out by an additional vessel from the company’s fleet.
The project was managed from Aberdeen in the UK, with support from DeepOcean’s offices in Haugesund and Oslo, Norway.
Nordseecluster A is the first phase of the 1.6 GW Nordseecluster project. The wind farm will comprise 44 Vestas V236-15.0 MW turbines and will have an installed capacity of 660 MW when fully commissioned in early 2027.
The project is jointly owned by RWE and Norges Bank Investment Management.
