Ecosse Subsea Systems has been contracted by JD-Contractor to carry out pre-cut trenching works on the 600MW Kriegers Flak offshore wind farm project in the Baltic Sea.
Energinet.dk plans to install two 220kV submarine export cables and a 9km connecting cable between two offshore platforms.
ESS commercial director Keith McDermott said: “To support the installation scope ESS will deploy our Scar 1 seabed system from JD-Contractor’s AHTS vessel to pre-cut trench along multiple sections where the seabed conditions are considered particularly challenging.
“Soils along the route are extremely variable and include sand, stiff clay and weathered limestone. In total, in excess of 20km of pre-cut trenching is anticipated along the routes.”
JD-Contractor director of international projects Kell Thyssen said: “Due to the varied nature of the seabed in the area, the KF Protection scope of work includes both pre-trenching works in shallow and deep water, as well as embedding by means of jetting.
“JD-Contractor will therefore utilise a range of different spreads for the protection work.”
