OSLO, Norway — Sevan SSP has developed a floating wind foundation, SWACH Wind, featuring a concrete construction option.
Inclusion of concrete adds flexibility as it allows for construction in a wider range of locations, the company says, allowing for increased local content and also offering potential for a reduction in carbon footprint.
The SWACH (Small Waterplane Area Cylindrical Hull) concept is designed for long-term operation (up to 50 years) in harsh environments, with a minimized volume of permanent equipment and a passive ballast system to lessen maintenance requirements.
SWACH Wind is a cylindrical floating foundation that can be scaled up to accommodate the largest wind turbines, the company says, with good motion characteristics in harsh conditions.
Lower motions are said to maximize power production, and the stability of the hull is said to support safe and reliable operations.
Other features include two stations for walk to work and a boat landing as well as access for crane vessels. The shallow draft allows the foundation to be fully assembled quayside with a wet tow to the final location.
