Norddeutsche Seekabelwerke GmbH (NSW) has contracted Vos Prodect Innovations BV to design and deliver inter-array cable hang-off systems for the Trianel Windpark Borkum II (TWB II) offshore wind project in the German North Sea.
The scope of works includes the delivery of sealed hang-off systems for the wind turbine generators and unsealed hang-off systems for the offshore substation. Sealed cable hang-offs are validated up to 2 bar air tightness, Vos Prodect said.
The systems are scheduled to be delivered in the first quarter of 2018.
Siem Offshore Contractors, the company in charge of the supply and installation of the inter-array grid cable system on the project, awarded NSW with a contract to provide a turnkey supply and installation of the inner-array grid cable system.
The construction of TWB II is scheduled to start in early 2018 and the wind farm’s 32 Senvion 6.2M152 turbines are expected to be connected to the grid by the end of 2019.
The offshore wind farm is located approximately 40 kilometres north of the island of Borkum, within the German Bight sector of the North Sea.
