SeaTwirl and the University of Tokyo have started a cooperation where the research group led by Associate Professor Shinichiro Hirabayashi at the Department of Ocean Technology, Policy and Environment, are looking to adapt SeaTwirls technology to Japanese conditions.

Japan is looking to floating wind to help meet their future renewable energy needs. Everything that is built must however be able to withstand the typhoons which frequently hit the country with wind speeds up to 55 meters per second, usually between May and October.

“Japan is very interesting and potentially large market for SeaTwirl. We take great pride in being able to cooperate with a prestigious institution like the University of Tokyo on adapting our technology to suit the special requirements of that market. Research is the first step towards commercialisation”,
said Peter Laurits, CEO of SeaTwirl.

“Floating offshore wind power generation could become a mainstream renewable energy source in Japan in the near future. We expect vertical-axis wind turbine as a possible solution for wind turbine on floating structures”,
said Shinichiro Hirabayashi, the University of Tokyo.

Swedish headquartered SeaTwirl has designed a divisible wind by turbine design which it claims reduces costs for installation and maintenance, and minimises downtime. In recent years it has secured patents in Sweden (2017), the US (2019), China (2019), Europe (2020) and more recently Japan (2021).

Earlier this month, SeaTwirl announced it had signed a letter of intent with Westcon Yards for the manufacture and installation of a floating S2x vertical-axis turbine on site in Norway. The S2x unit has a height of 55m above sea level, a depth of 80m under the surface and a turbine with a diameter of 50m.
It follows news March that SeaTwirl announced it received an approved concession for the installation of the S2x turbine in Bokn municipality, Norway. SeaTwirl, together with Marin Energi Testsenter AS (MET), previously applied for a concession period of five years. The installation site for S2x is planned to be located in Boknafjorden, northeast of Lauplandsholmen.
