Siem Offshore Contractors Nets Hornsea One Gig

DONG Energy has awarded Siem Offshore Contractors (SOC) with a contract for the transport and installation of parts of the inner-array grid cable system for the 1.2GW Hornsea Project One offshore wind farm.

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 commence immediately, with the offshore installation works currently scheduled to be undertaken as of Q4 2018.

The Hornsea Project One offshore wind farm is located approximately 120km off the Yorkshire coast within the central North Sea sector, and will comprise 174 Siemens 7MW wind turbines, which will be interconnected by 33kV medium voltage alternating current submarine composite cables.

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

On completion in 2020, Hornsea Project One will be the world’s first offshore wind farm to exceed 1,000MW in capacity.

DONG Energy recently awarded JDR with a contract to supply subsea power cables for the offshore wind farm. The contract will see JDR design and manufacture 242km of array cables, covering two thirds of the total wind farm capacity.
