Sif-Smulders Team Bags Trianel Windpark Borkum II Contract

Seaway Heavy Lifting has awarded Sif Holding, in a joint venture with Smulders, a contract for production of all monopiles and transition pieces for the Trianel Windpark Borkum II (TWB II) offshore wind farm.

Sif will produce monopiles and the primary steel for the transition pieces and Smulders will be responsible for the secondary steel and outfitting of the transition pieces.

The companies will manufacture the foundation components together accounting for approximately 32 Ktons during the first half of 2018. This will bring Sif’s orderbook for 2018 to 129 Ktons, the company stated.

The offshore construction is scheduled to start with the installation of the first monopiles in the spring of 2018, and the erection of wind turbines and commissioning are expected to be completed by the end of 2019 at the latest.

Senvion will deliver 32 of its 6.2M152 offshore wind turbines and accompanying services for the project, while Seaway Heavy Lifting was awarded an EPCI contract for the foundations. Siem Offshore Contractors is in charge of supply and installation of the inter-array grid cable system.

The offshore wind farm is located approximately 40 kilometres north of the island of Borkum, within the German Bight sector of the North Sea. TWB II will have an installed capacity of approximately 203MW.

The first phase of Trianel Windpark Borkum with a capacity of 200MW became fully operational in mid-July 2015.
