Leading developer in floating offshore wind Equinor has designed a new floating wind concept that will enable industrial standardisation and maximise opportunities for local supply chains. Having reaffirmed its commitment to Scotland earlier this year, the offshore energy company has now revealed its preferred floating wind foundation design for full-scale gigawatt (GW) commercial floating offshore wind, if successful in ScotWind. The Wind Semi, a semisubmersible wind turbine foundation, has been designed with flexibility, specifically to allow for fabrication and assembly based on local supply chain capabilities. To ensure that the technology can be deployed cost effectively whilst maximising local benefits, Equinor has developed a set of design principles and solutions that are applicable across floating concepts.Equinor installed the first ever floating offshore wind turbine in 2009, and operates Hywind Scotland (30 MW), the world’s first floating wind farm. Since it began production in 2017, Hywind Scotland has consistently achieved a higher capacity factor than other UK wind farms, demonstrating the true potential of floating offshore wind.The Wind Semi has several features making it particularly suited for harsh waters, and solutions that can maximise the opportunities for the Scottish supply chain: Increased dependability: By introducing a passive ballast system, the Wind Semi has a simple substructure design, reducing the risk of system failure and the amount of maintenance needed Simpler, more robust design: A flat plate design that is free from bracings, heave plates and complicated nodes that are prone to fatigue cracking Flexibility towards the supply chain: With a harbour draught of less than 10 m, the Wind Semi’s turbine integration can be assembled at most industrialised ports. The Wind Semi’s simpler flat plate design enables the substructure to be built in blocks that can either be fabricated locally and/or shipped from other locations. Equinor will select the best suited floating wind concept for its projects. Water depths, conditions around shipyards and ports, and the specialisations and capacity of the local supply chain are primary drivers for selecting a given design.
