Simplified and cheaper maintenance of SeaTwirl’s new vertical axis floating offshore wind turbine

SeaTwirl intends to demonstrate its floating vertical axis technology at a test site off the west coast of Norway.

Swedish designer of floating wind platforms SeaTwirl has obtained permission to install a 1 MW prototype of its vertical axis turbine at a test site in Norway.

Together with the Marine Energy Test Center (Met Center), it will seek to demonstrate the concept at a site off the municipality of Bokn in western Norway during a five-year concession.

The manufacturer has built a 30kW prototype, which it claims has proven to be stable and able to withstand major storms.

He now intends to demonstrate the concept and benefits of a larger system with the 1MW S2x platform.

The S2x turbine will reach 55m above the water surface, 80m below sea level and has a rotor diameter of 50m.

It will be installed in a former fish farm located 700 m from the coast and 130 m deep.

SeaTwirl claims its concept has a simple, robust design with a low center of gravity, while its moving parts are located near the water’s surface, allowing for easier and cheaper maintenance.

The S2x demo will connect to an existing transformer substation on land. The Norwegian company Hauguland Kraft will buy the electricity produced.

SeaTwirl intends to sell a business unit to a blue chip energy company by 2025.

Research has suggested that vertical-axis wind turbines installed in certain configurations could outperform traditional horizontal-axis wind turbines, but aerodynamicists have disputed the findings.
