Spanish engineering consultancy Saitec Offshore has been awarded a patent for its Sath (Swing Around Twin Hull) floating wind concept by the Japanese Patent Office.

The certification constitutes “a big step for our great ambitions in [this] market”, said Saitec.

The patent-award comes after the Bilbao-headquartered company received a break-out €2m European Commission (EC) grant to build a part-scale version of its innovative concrete-pontoon-based design, which Saitec calculates could generate at a “levelised cost of energy like onshore wind” when built at its full 10MW-plus size.
