SLPE scoops follow-up foundation design contract for Inch Cape

Inch Cape Offshore has awarded SLPE the detailed design contract for what will be some of the largest offshore wind farm monopiles in the world, after the engineering consultancy successfully delivering the concept design last year.

After delivering the wind turbine generator (WTG) foundation concept design in March 2021, SLPE will soon start work on the detailed design stage.

SLPE managing director Joseph Hilton explained in a recent release that the concept design phase was followed by a refinement phase to further optimise the designs “for a number of variables and uncertainties”.

“These studies will contribute to the detailed design of monopiles that will support some of the largest offshore wind turbines in the market today. Inch Cape is also currently the deepest offshore wind farm in which monopile foundations are planned to be deployed,” he added.

The Inch Cape offshore wind farm will be located 15-22km off the Angus coastline in Scotland, with water depths ranging from 43m to 55m. It will include up to 72 turbines and connect to the National Grid at Cockenzie, East Lothian.

In July of last year, Scottish ministers agreed to remove the 1,000MW maximum generating capacity cap from the project’s consent. This means it can use the most powerful turbines on the market.

SLPE is supporting Inch Cape with further concept refinement work and site investigations. This is to help inform key project decisions and develop design inputs for the detailed design.

In the coming days, a jack-up vessel operated by Fugro Seacore will also begin a near-shore survey close to the coast at Cockenzie to gather further data to inform the design.

SLPE WTG substructures head Nick Terr said: “With water depths of up to 55m, the monopiles for Inch Cape will be among the largest in the world.

“Being able to demonstrate the feasibility of monopiles in these water depths has delivered significant cost savings to the project, when compared against jacket foundations. This has been made possible by our in-house iterative design and optimisation software, which enables each location-specific monopile design to be individually optimised for both structural weight and cost-effective fabrication.

“Our monopile designs also incorporate advanced Pisa-type geotechnical design, using full 3D finite element analysis and advanced soil constitutive modelling to simulate the soil-structure behaviour. This results in higher accuracy and considerable weight savings compared to conventional pile design methods. This advanced approach is delivered in partnership with Geowynd, who complement SLPE with their deep expertise in marine geotechnics.”

As Inch Cape moves into the next phase of design, Red Rock Power project director Adam Ezzamel said the project was “actively seeking similarly innovative and ambitious UK-based companies” to support its delivery.

The wind farm is owned by Inch Cape Offshore, an equal joint venture between Edinburgh based renewable and sustainable energy company Red Rock Power and Irish energy company ESB.

Once complete, Inch Cape could power up to 1M households and become one of the country’s largest single sources of renewable energy.
