BV to certify first floating wind farm in Celtic Sea

Classification society Bureau Veritas (BV) is to certify the Erebus wind farm, the first floating facility off the Welsh coast in the Celtic Sea. The farm, due to be commissioned in 2026, lies some 44 km off the Pembrokeshire coast in waters about 75m deep. Erebus will generate about 100 MW of energy, sufficient to provide renewable power to an estimated 93,000 homes.

The project is being undertaken by TotalEnergies and the Simply Blue Group in a joint venture called Blue Gem Wind. The floating design, which received Approval in Principle from BV in 2016, will be based on Windfloat® technology, developed by California-based Principle Power Inc.

The three-column semi-submersible platform, ballasted to compensate for changes in wind speed and direction and moored with a five-line catenary system, will support the latest generation of multi-megawatt wind turbine generators, BV said.

The classification society will provide services across all the design phases. These will include site condition assessment, design basis evaluation, integrated load analysis, and detailed design evaluation for all components, including inter-array cables. BV will deploy its integrated modelling tool, Opera, to assess the complex physics of the working structure, its components and their interaction, as well as seakeeping and station-keeping characteristics.

Paul Shrieve, BV Marine & Offshore’s vice president Global Services, said: “We are honoured to be part of this new venture in the Celtic Sea. I am also proud to see our continued leadership in mitigating risks in marine renewable energy, through our expertise and tools such as Opera, giving our clients the peace of mind they need when de-risking these complex projects.”
