Designed for the floating environment from the start

SeaTwirl’s unique floating vertical-axis wind turbine is a robust solution designed for the deep-water offshore environment from the start. A low center of gravity, enabled by integrating the tower and the spar into one rotating unit, provides many beneficial qualities. It means the floater can use less steel than conventional floating solutions, the turbine enables easier access for service and maintenance which results in lower maintenance costs and the possibility of using locally available vessels. SeaTwirl’s turbines can be anchored at greater depths than conventional wind turbines which enables installations further out to sea where winds are stronger.

02 / Our Concept

Reduction of the number of moving parts, sturdiness and ease of maintenance have been the design drivers behind SeaTwirl’s concept. The wind turbines consist of three main parts: the SPAR which provides buoyancy and stability, the Generator house containing all systems where the rotation motion is converted to electricity, and the turbine transforming the kinetic energy from the wind into rotating motion. The Generator house is connected to the mooring which restrain the unit’s motion both in displacement and rotation. The power is exported from the wind turbine via a power cable connected to the bottom of the lower part of Generator house. SeaTwirl offers turbines for different applications and sites, the product is flexible and develops after different requirements.
