Hornsea 2 Cable Installation Contract for Boskalis

Boskalis has won the offshore export cable installation contract for the Hornsea 2 offshore wind farm, located approximately 90 kilometers off the Yorkshire coast. 

The contract with a value greater than EUR 100 million was awarded by Ørsted Wind Power A/S and consists of three export cable circuits with a total length of approximately 380 kilometers.

According an official announcement, 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 kilometer long export cables will connect the offshore substation to the onshore substation by means of a 300 meter long horizontal directional drilling, crossing the sea defense of Horseshoe Point, UK.

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

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