In the SEASTAR project, coordinator Nova Innovation (Nova) leads a world-class team to deliver a 4MW array of 16 tidal stream turbines at the EMEC Fall of Warness tidal site in Orkney - the world’s first large tidal farm, which will contain more tidal turbines than are currently deployed worldwide. SEASTAR will utilise Nova's well-proven M100D turbine, developed in partnership with project partner SKF - the world’s leading supplier of rotating equipment. The project builds on the success of Nova's six-turbine Shetland Tidal Array - the world's first offshore tidal array - which was delivered under the H2020 EnFAIT project by a team including SEASTAR partners SKF and Wood. They are joined in SEASTAR by DLA Piper, the leading global law firm in renewable energy, and by specialists in sustainability, insurance, consenting, communication, engineering and offshore operations. SEASTAR will demonstrate for the first time the industrial systems, manufacturing and operational techniques required to efficiently deliver a large tidal farm. It will generate and share transferable knowledge on key consenting risks, de-risking future large arrays globally. And it will improve the bankability of tidal energy by cutting costs, proving performance, and enhancing the insurability of large tidal farms. SEASTAR represents a step change for tidal energy. Volume industrial manufacturing, operation and maintenance techniques will be applied for the first time to the full lifecycle of a tidal farm, from design, procurement, production, shipping, marshalling, deployment, commissioning, operation and decommissioning. The 16-turbine farm provides unique opportunities to address critical environmental evidence gaps and develop the cost-effective, reliable monitoring solutions at scale required to accelerate permitting and remove barriers for future large tidal farms.
