SeaTwirl has been granted a patent for a divisible wind by turbine by the Japanese Patent Office. SeaTwirl has already secured the same patent in Sweden, USA, China, and Europe.

The patent protects a solution where the wind turbine is divisible above and below the house that holds the generator and bearing, which means that the entire generator and bearing housing can be replaced just above the water surface by boat. SeaTwirl claims that it reduces costs for installation and maintenance, and minimises downtime.


The corresponding patent was approved in Sweden in 2017, in the US and China in 2019 and Europe in 2020. The notice from the Japanese Patent Office is dependent on SeaTwirl paying the required fees.

“Japan has great water depths and large cities along the coasts, which is an interesting market for our floating wind turbine, especially when Japan has set a goal of becoming CO2 neutral by 2050. To protect our ideas and technologies in the future, we put a lot of focus on our patent strategy. Our strong patent portfolio is one of our biggest assets”, says CEO Peter Laurits.
