Description
OMM secured a construction-phase contract from transpower for BorWin1 to install two infield HVAC power cables between the principal offshore platforms in the German North Sea. OMM’s scope covered end-to-end subsea cable installation works, including preparatory activities, J-tube and route inspections, topside preparations for pull-ins, pre-lay grapnel runs, laying and monitoring of the two approximately 1.1 km HVAC cables, post-lay burial to achieve adequate protection, and post-lay burial surveys with final reporting and charting. Operations were conducted from a DP2 vessel, with Hallin Marine and Modus engaged as subcontractors to provide specialised vessels and equipment. The contract focused on delivering the short inter-platform AC link integral to the BorWin1 offshore grid connection.
