Project Phase Inner Array Cable installation in Offshore Wind Farm TWB II finalized.


Bremen, April 23, 2019 – After around eight months, TRACTEBEL DOC OFFSHORE GmbH (DOC) has completed construction supervision of the inner array cabling for the Trianel Borkum II Offshore Wind Farm (TWB II) on behalf of Trianel Windkraftwerk Borkum II GmbH & Co. KG (TWB II). Currently at the end of the project phase "Laying the inner array cable system", the DOC team can look back on over 650 successful offshore man days.


"DOC has always provided the project with the required quality and number of representatives in a flexible manner, thus meeting our expectations in a targeted and satisfactory manner," emphasizes the project manager responsible for cable installation at TWB II. DOC supported the municipal offshore wind farm on the North Sea with up to 14 DOC offshore experts, from the loading of the cables, the necessary preparatory work on the transformer station and on the foundation structures, the subsequent cable laying and installation, to the connection work of the cables in the foundation structures and the concrete mattress installation for weighting the inner array cables.

Since mid-August 2018, DOC has been able to contribute its own core competencies to the completion of the inner array cable system. Communications with the project office on land and quality assurance were further components of the DOC work package.

The cable installation work was carried out with the Seaway Aimery, the Seaway Moxie, the Olympic Ares and the EDT Jane.


"The cooperation on the construction site and with our client was without exception positive. We are proud that we could contribute our part to the Trianel wind farm Borkum II in the area of our core competencies", states Oliver Spalthoff, Managing Director of TRACTEBEL DOC OFFSHORE GmbH.
