Norway's Subsea 7 has won a "sizeable" deal to install cables for a UK wind farm.

The Kristian Siem-backed offshore engineering company, which owns a fleet of offshore vessels, said the contract is worth between $50m and $150m.

Its Seaway 7 unit will carry out work on the Hornsea Two offshore wind farm project run by Optimus Wind, a subsidiary of the Orsted Group.
