Seaway 7 has won a deal to install the full infield cable system at Orsted’s 1386MW Hornsea 2 wind farm off east England.
The Subsea 7 business will begin engineering immediately with offshore activities to start in 2021.
The company will install 165 66kV array wires with a total length of 420km.
Included in the scope is a pre-installation submarine cable route survey, pre-installation boulder clearance activities and post-lay trenching services.
Subsea 7 renewables and heavy lifting senior vice president Steph McNeill said: “We look forward to continuing our collaborative relationship with Orsted to install the entire inner array grid cable system on the Hornsea 2 offshore wind farm project.
“This award follows on from our reliable performance and successful completion of the installation activities for the Hornsea One offshore wind farm project earlier this year.”
Hornsea 2 will feature Siemens Gamesa 8.4MW turbines due online in 2022.
