Allseas and Heerema bag Tennet platforms installation deal

 

Offshore construction specialists Allseas and Heerema Marine Contractors (HMC) have secured multi-year framework agreements with transmission grid operator TenneT to transport and install at least 14 supersized offshore wind converter stations in the Dutch and German parts of the North Sea.

Under the framework deal, which covers at least twenty-eight slots for fourteen jackets and the same number of topsides, Heerema has been awarded about 60% of the available slots, while Allseas has secured approximately 40% of the slots.

The Dutch-based HMC will deploy its semisubmersible crane vessel Sleipnir as well as an owned floatover barge, and the Swiss-headquartered Allseas will use its single-lift installation vessel Pioneering Spirit for the installation of the jackets and topsides. Boskalis will act as a subcontractor to Allseas, building one or two new transport vessels.

In April this year, Belgium, Denmark, Germany, the Netherlands, France, Ireland, Luxembourg, Norway and the UK committed to jointly install at least 120 GW of offshore wind power capacity by 2030. TenneT will account for about one-third of this volume.
