Heerema Marine Contractors has completed its first North Sea campaign of 2026 with the installation of the TenneT BorWin6 jacket in the German North Sea on behalf of McDermott International, Ltd.
The steel structure, weighing nearly 5,000 tonnes, is now fixed to the seabed with 10 piles, preparing the site for the topside float-over later this year.
According to the company, the campaign was delivered through close cooperation, with all activities planned and executed in line with German offshore regulations. This included compliance with strict underwater noise limits during piling and specific grouting requirements.
The installation marks a key step in completing the BorWin6 grid connection and helping bring more offshore wind power into the German energy system.
Heerema Marine Contractors said the campaign reflected the work of its offshore and onshore teams and thanked McDermott International, Ltd. and TenneT for their partnership.
