NSW to deliver and install the inter-array cabling for the offshore wind farm MeerwindOn July 8, 2011 WindMW GmbH and Norddeutsche Seekabelwerke GmbH (NSW) signed a contract for the delivery and installation of 108 km medium-voltage submarine cables for the inter-array cabling of the wind farm project Meerwind. With the installation scheduled to start in the second half of 2012, completion is planned in 2013.


The project Meerwind consists of the two offshore wind farms Meerwind Süd and Meerwind Ost which are located 23 km north of the island Helgoland in the North Sea. It is planned to use the island as maintenance base. Both wind farms together will be able to generate 288 MW.

For the connection of a total of 80 turbines, NSW will produce 88 cable sections. The installation of the cables in water depths of 22 to 26 meters will be carried out using NOSTAG 10, a barge specially designed for cable-laying, which the company has already used successfully in comparable projects. NOSTAG 10 is owned by a consortium of NSW, Hans Schramm & Sohn GmbH & Co. KG and Tiefbau-GmbH "Unterweser" (TAGU).

Jens Assheuer, Managing Director WindMW: "The assignment of the cable delivery and installation is a further step towards the successful realisation of the project. We are happy to have won with NSW another reliable and experienced supplier of the region for the construction."

Thorsten Schwarz, Managing Director NSW: "As a neighbouring company in the Wesermarsch region we are particularly proud of having convinced the customer with our turnkey offer for supply and delivery of array cables and of our capability even in an international comparison and thus having secured jobs in the German offshore wind industry for the region. The proximity to the harbour of Helgoland presents the unique opportunity for using the installation solution NOSTAG 10 plus vertical injector, which has already been successfully used in this sea area."
