Dutch marine outfit Boskalis has signed a pre-construction agreement for the installation of jacket foundations and the offshore substation at the over 700MW Inch Cape offshore wind farm off the Angus coast of Scotland.
The deal, first reported in the 6 December subscriber-only newsletter reNEWS, is with Inch Cape Offshore Limited, a subsidiary of Red Rock Power.
It covers the engineering, supply, transportation and installation of up to 72 pre-piled jackets, as well as the transportation and installation of the offshore substation.
The Bokalift 1 crane vessel (pictured) will be deployed for the transportation and installation of the foundations as well as the substation foundation, sub-structure and topside.
Boskalis had previously announced a deal for the project’s 84 inter-array cables and, in consortium with NKT, will also supply and install two 85km export cables.
The company said the contract is subject to a successful bid by the developer in the next UK Contracts for Difference auction later this year and financial close of the project, which is expected in the second half of 2020.
It added that the contract size, excluding procurement, is expected to exceed €200m.
Boskalis will also in the coming months assist with the further engineering and design of Inch Cape.
“The ultimate size of the contract including the cost associated with the supply of the wind turbine foundations and inter-array cables will be determined during this period,” it said.
The project is scheduled to be executed in the period 2021-2022, in time to enable Inch Cape to meet the CfD 3 delivery windows between 2023 to 2025, Boskalis added.
