More than a year and a half after the first cable for Borkum Riffgrund 3 was installed in the German part of the North Sea, the cable-laying vessel BOKA Ocean has now completed the final inter-array cable for Ørsted’s 913 MW offshore wind project. The latest campaign also included additional fiber optic cables and marine detection systems.
When that initial cable was placed by the then-new BOKA Ocean, it signalled the start of a multi-phase installation programme at the site. In total, four separate installation campaigns have been carried out to build out the inter-array cable network.

The most recent phase was executed in close cooperation with the multipurpose offshore vessel Ndeavor. While BOKA Ocean focused on laying the subsea cables, Ndeavor followed to bury them, forming a coordinated spread that delivered the cable installation and burial work across the site.
The area is already familiar to Boskalis. Earlier this year, the company placed the offshore converter station DolWin epsilon in the same region, supported by several oceangoing tugs and a rock-installation vessel working subsea, Rockpiper. With cable installation now finished and the wind farm having recently achieved first power, the development of Borkum Riffgrund 3 is moving towards completion.
The company highlights the contribution of the crews on all vessels involved and thanks client Ørsted for the trust and cooperation shown during the project.
