JDR Cables has contracted offshore vessel Olympic Commander to support a maintenance campaign on the Sandbank offshore wind farm in the German North Sea.
The vessel, equipped with a 28 metre-long Safeway Seagull type walk-to-work gangway system, has been deployed for the transfer of people and goods during the campaign.
The presence of a smart Safeway A-Frame construction at the boom tip of the Seagull gangway also allows the operator to switch rapidly from “people transfer” to “cargo transfer” modes, activating a lift capacity of 1000kg.
The Sandbank offshore wind farm, 90km from shore, has been operational since 2017.
It is the second joint project between Vattenfall and Stadtwerke Munchen, after the DanTysk wind farm.
The vessel will enable JDR technicians to carry out maintenance works on the array cables between the offshore substation and the 72 Siemens Gamesa wind turbines.
These cables contain an optical fibre that allows for data exchange between each wind turbine and the OSS, as well as the remote control and surveillance of the wind farm by Vattenfall in Esbjerg, Denmark.
