Boskalis awarded Hornsea 2 offshore export cable installation contract

Royal Boskalis Westminster has been awarded the offshore export cable installation contract for the Hornsea 2 offshore wind farm.

The contract, which has a value greater than €100 million (US$111 million), was awarded by Ørsted Wind Power and consists of three export cable circuits with a total length of approximately 380 kilometres.

The project scope includes the preparation of the offshore export cable route (geophysical survey, boulder clearance, and seabed leveling through dredging) and the installation and protection of the cables. The three 130-kilometre-long export cables will connect the offshore substation to the onshore substation by means of a 300-metre-long horizontal directional drilling, crossing the sea defence of Horseshoe Point, UK.

The project is expected to commence later this year with a planned completion in late 2021.

Boskalis will deploy a variety of in-house specialist services and assets including a trailing suction hopper dredger (TSHD), a geophysical survey vessel, and multiple cable-laying vessels.

The Hornsea 2 offshore wind farm will consist of up to 165 turbines with a maximum capacity of 1.4 GW and is located approximately 90 kilometres off the Yorkshire coast.
