Seaway 7, the renewables and heavy lifting business unit of Subsea 7, has been awarded a major contract by Optimus Wind, a subsidiary of the Ørsted Group, for the installation of the entire inner array grid cable system for the Hornsea Two offshore wind farm project in the North Sea.
The inner array grid cable system consists of 165 66kV copper-core submarine composite cables with a total length of more than 420km.
In addition to the submarine cable installation works, Seaway 7 will also undertake a pre-installation submarine cable route survey, perform pre-installation boulder clearance activities and execute post-lay trenching services.
Project engineering will commence immediately and offshore activities are due to commence in 2021.
“We look forward to continuing our collaborative relationship with Ørsted to install the entire inner array grid cable system on the Hornsea Two 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,” said Steph McNeill, Subsea 7’s SVP renewables and heavy lifting.
