BV to Certify First Offshore Wind Farm in Celtic Sea
Bureau Veritas (BV) has been selected to undertake the project certification of Erebus, the first offshore wind farm in the Celtic Sea, in Wales, and one of the largest floating offshore wind projects in the world.
Located 44 km from the Pembrokeshire coastline in up to 75-m water depth, the Erebus project aims to be fully operational by 2026 and will deliver up to 100 MW of clean energy, powering 93,000 homes per year.
The Erebus project is the result of TotalEnergies teaming up with Simply Blue Group in a joint venture named Blue Gem Wind. Principle Power Inc. will design the floating platforms, based on the latest generation of its Windfloat technology. This floater concept received an approval in principle from BV in 2016. The ballasted, semisumbersible platform supports latest generation, multimegawatt wind turbine generators. The three-column platform is moored with a five-line catenary mooring system and is equipped with a closed-loop ballast system to compensate for changes in mean wind velocity and direction.
BV will provide independent verification and project certification in line with regulatory requirements. The scope of the evaluation includes all the design phases: site condition assessment, design basis evaluation, integrated load analysis and detailed design evaluation for all the components of the floating wind turbines, including the interarray cables. To support the design documentation review, BV will provide independent analysis leveraging its integrated modeling tool, Opera, which accounts for all components of a floating asset or wind turbine, covering everything from mooring systems to blades. Opera addresses the complex physics of aero-hydro couplings and multibody interactions and manages sea-keeping and station-keeping for floating structures.
BV’s certification scope is planned to include all post-design phases, from manufacturing to operations, including transportation and installation (T&I) and commissioning.
