Glosten Associates Inc., an engineering consultancy based in Seattle, has formally announced plans to commercialize its PelaStar floating wind turbine platform and make the technology available to the global offshore wind energy industry within the year. The technology was recently selected for an intermediate-scale prototype installation project, with deployment planned for next summer at a site in the northeastern U.S.
PelaStar's tension leg platform (TLP) combines technology that has been adapted from the oil and gas industry. Benefits of the TLP include minimal motion, minimal steel weight, and complete quayside integration of the turbine and tower on the PelaStar foundation, according to the company.
PelaStar can be used for fully exposed, open-ocean sites with water depths greater than 60 meters, where bottom-fixed jacket structures become costly, according to Glosten. The baseline PelaStar design supports current 5 MW to 6 MW offshore wind turbine systems and is being scaled to support next-generation turbines of 10 MW and greater.
