The German operations of energy and marine consultancy ABL have been tasked by TenneT to provide marine warranty survey (MWS) services for the subsea cable interconnections between two of Germany’s offshore wind farms, N-3.7 and N-3.8, and the Dolwin 6 offshore converter station.

The three subsea cables to be installed are 40 kilometres long in total. The installation will involve crossing dozens of other cables along the routes. ABL’s scope of work will include the technical review and approval of all documentation, procedures, and drawings related to the warranted activities, as well as suitability surveys and, where necessary, dynamic positioning (DP) trials of the proposed fleet for operations. ABL will also provide on-site attendance at fabrication and loadout sites, and offshore, to review and approve transportation and installation (T&I) operations. ABL’s scope of work will be concluded in 2026.
