Royal Boskalis Westminster has signed both a multi-year subsea services agreement in the Middle East and an exclusive Pre-Construction Agreement (PCA) for the Inch Cape offshore wind farm project.

The base value of the three-year subsea services contract amounts to USD 40 million with an option to extend. Under the terms of the contract, Boskalis will carry out a broad spectrum of subsea IRM services including integrity assessments for offshore platforms and tripods, wellhead jacket inspections, integrity assessments and inspections of pipelines and light ad-hoc construction work.

Boskalis will deploy the diving support vessel BOKA Constructor with ROV for this contract, fully crewed with air diving/ROV teams and options for saturation diving.

Inch Cape Offshore Wind Farm Project

Boskalis also signed an exclusive Pre-Construction Agreement (PCA) with Inch Cape Offshore Limited (ICOL), a subsidiary of Red Rock Power Ltd. The project scope includes the transportation and installation of the wind turbine foundations, the offshore substation and cables for the Inch Cape Offshore Wind Farm Project.

The award of the contract is subject to a successful bid by ICOL in the next UK Contracts for Difference auction (mid 2019) and financial close (second half of 2020). The contract size, excluding procurement, is expected to exceed EUR 200 million. Boskalis will in the coming months assist with the further engineering and design of the project. 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.

The Inch Cape offshore wind farm will be located in the North Sea, 15 km off the Angus Coast in the East of Scotland. Boskalis aims to maximise UK local content for its scope of work. 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.

72 Jacket Foundations and Inter-array and Export Cables

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. The Bokalift 1 crane vessel will be deployed for the transportation and installation of the foundations as well as the offshore substation foundation, sub-structure and topside.

Furthermore, Boskalis will in consortium with NKT supply and install two export cables of 85 km each, connecting the offshore substation to the mainland.
