A pre-construction agreement (PCA) for work on a windfarm off the coast of Scotland has been signed by Dutch-based dredging, offshore contracting and marine services company Boskalis Westminster.
The project is the Inch Cape offshore windfarm project, and the award was made by Inch Cape Offshore Ltd (ICOL), a subsidiary of Red Rock Power. The work will include the transportation and installation of the wind turbine foundations, the offshore substation and cables.
The award of the contract is subject to a successful bid by ICOL in the next UK Contracts for Difference (CfD) auction in mid-2019, and financial close in the second half of 2020.
The CfD scheme is the UK government’s main mechanism for supporting low-carbon electricity generation.
The Inch Cape contract, excluding procurement, is expected to be more than €200 million.
Boskalis said it would, in the coming months, assist with the further engineering and design of the project. The final contract cost, including the amount associated with the supply of the wind turbine foundations and inter-array cables, will be determined during this period.
The PCA includes the engineering, supply, transportation and installation of up to 72 pre-piled jacket foundations and up to 84 inter-array cables in addition to the transportation and installation of the offshore substation.
Boskalis said the Bokalift 1 crane vessel would be deployed for the transportation and installation of the foundations, as well as the offshore substation foundation, sub-structure and topside.
Also, the company said it would supply and install two 85km export cables to connect the offshore substation to the mainland, in a consortium with NKT.
The Inch Cape offshore wind farm will be located in the North Sea, 15km off the Angus Coast in the East of Scotland.
The project is scheduled for 2021 to 2022, in time to enable Inch Cape to meet the CfD 3 delivery windows between 2023 and 2025.
