Seaway7 Lands Inch Cape Transportation and Installation Job

December 17, 2024, by Adnan Memija

Seaway7, part of the Subsea7 Group, has been awarded a contract by Inch Cape Offshore Limited (ICOL), a joint venture between ESB and Red Rock Renewables, for the transport and installation of pin-pile jacket foundations and transition pieces (TPs) for the 1.1 GW offshore wind project.

The deal is worth between USD 150 million and USD 300 million, as per Subsea7’s definition of a substantial contract.

Seaway7’s scope of work includes the transport and installation of 18 pin-pile jacket foundations and 54 TPs, with offshore work expected to begin in 2026.

Located 15 kilometres off the Angus coast in the Scottish North Sea, the Inch Cape offshore wind farm will feature 72 Vestas V236-15.0 MW turbines.

The turbines will be installed on a combination of monopile and jacket foundations in water depths ranging from 34 metres to 64 metres.

At the beginning of this year, ICOL inked reservation agreements with Dajin Offshore Heavy Industry and Guangzhou Wenchong Shipyard Heavy Industry (GWSHI) for XXL monopile foundations.

The wind turbines will be installed by Cadeler under a contract signed with the developer in June 2024.

There will be one 66 kV/220 kV substation on a jacket foundation at the heart of the project. Renewable energy from the offshore substation will be transmitted 85 kilometres via two 220 kV subsea export cables to landfall in Cockenzie, East Lothian.

The 1.1 GW Inch Cape offshore wind farm is expected to be fully operational in 2027.

In terms of other news coming from Seaway7, the company recently signed a vessel reservation agreement with Dogger Bank Wind Farm to support the turbine installation work at the site off the coast of England.

Starting in 2026, the Seaway Ventus jack-up installation vessel is planned to kick off turbine transport and installation work of GE Vernova’s Haliade-X turbines.
