ABL has been tasked by TenneT to provide marine warranty survey (MWS) services for the subsea cable interconnections between two of Germany’s offshore wind farms and the Dolwin 6 offshore converter station.
The three subsea cables to be installed between N-3.7 and N-3.8 and Dolwin 6 are 40 kilometres long in total.
The installation will involve the crossing of dozens of other cables along the installation 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 resource on-site attendances at fabrication and loadout sites, and offshore, to review and approve transportation and installation (T&I) operations.
ABL Germany, based in Hamburg, will deliver the scope of work under an existing framework agreement with TenneT, a leading European grid operator.
Tilo Klappenbach, ABL Germany’s country manager, said: “ABL Germany has long been supporting TenneT’s subsea cable installations, driving maximum safety and efficiency throughout marine operations, thereby enabling maximum value from these all-important assets.
“We are really pleased to continue collaborating with them.”
ABL’s scope of work will be concluded in 2026.
