Seaway 7 Completes Dogger Bank Trifecta

Seaway 7 ASA has been awarded a contract by Dogger Bank Wind Farm for the transport and installation of monopile foundations and transition pieces on the third phase of the Dogger Bank Offshore Wind Farm, Dogger Bank C.

The contract is valued between USD 50 million and USD 150 million.

Seaway 7 will utilise their specialist heavy lift vessel Alfa Lift, and offshore installation will commence in 2024 following the installation of the Dogger Bank A and B phases.

OHT, now part of Seaway 7, secured contracts to transport and install the turbine foundations on Dogger Bank A and B back in the summer of 2020.

Stuart Fitzgerald, Chief Executive Officer of Seaway 7, said: ”We are pleased to have been awarded the work to install foundations on all three phases of the world’s largest offshore wind farm. We look forward to executing the work with quality and safety at the forefront and to working closely with our customer to deliver on the project objectives.”

The contract award is subject to Dogger Bank C reaching financial close by the end of 2021.

”It’s great to be able to confirm that Seaway 7 has been awarded this contract. The Alfa Lift is one of the most innovative heavy transportation and installation vessels on the market and we are very pleased to have them working with us across all three phases as we deliver this ground-breaking project,” Steve Wilson, Project Director for Dogger Bank, said.

The 3.6 GW Dogger Bank Wind Farm, which is to be built more than 130 kilometres off the Yorkshire coast in the North Sea, is currently being developed in three 1.2 GW phases: Dogger Bank A, B, and C.

Phases A and B are planned to be operational by 2024, and phase C will follow later with the operation date scheduled for 2026. 

Dogger Bank A and B is a joint venture between SSE Renewables (40 per cent), Equinor (40 per cent) and Eni (20 per cent).

In November 2021, SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20 per cent stake in the final phase, with SSE Renewables and Equinor maintaining 40 per cent stakes each, in a deal that is expected to complete in the first quarter of 2022.
