Siem Offshore Contractors (SOC), a wholly owned subsidiary of Siem Offshore, has been awarded the contract for the transport and installation of parts of the inner array grid cable system for the Hornsea Offshore Wind Farm Project One by DONG Energy Wind Power.

The contract award builds upon the recent establishment of a UK office by SOC in Aberdeen.

The offshore wind farm is located approximately 120 km off the Yorkshire coast within the central North Sea sector of Great Britain, covering approximately 407 km² and comprises 174 x 7 MW wind turbine generators, which will be inter-connected by 33 kV medium voltage alternating current submarine composite cables.

SOC’s scope of work includes the installation of 81 submarine composite cables as well as the associated post-lay trenching works.

The project engineering works will start immediately. The marine installation works are currently scheduled to be undertaken as of Q4 2018.
