VIDEO: Siem Duo Gets Busy at Nordsee One

Siem Offshore Contractors GmbH ( SOC) has shared a video of two of its vessels, the cable lay vessel Siem Aimery and the installation support vessel Siem Moxie, laying inter-array cables at the 332MW Nordsee One offshore wind farm in the North Sea.

Siem worked at the site from June to August 2016. The inter-array cables were supplied by JDR Cable Systems.

Once installed, the wind farm’s 54 6.15MW turbines will be connected to the offshore substation by ten strings of cables with an overall length of approximately 70 kilometres.

Siem is in charge of supplying and installing the inter-array cables for Nordsee One. The submarine cables have a diameter of up to 160 mm.

Nordsee One is owned by Northland Power Inc. (85%) and RWE International SE (15%). The wind farm is located approximately 40 kilometres north of the island of Juist in the German part of the North Sea.

The commissioning is scheduled for 2017.
