SeaTwirl S1: A small-scale workhorse

30 kW

The low power output can be used for specialised application areas.

Released in 2015

The SeaTwirl S1 has withstood the test of time and weather.

The Concept Model

SeaTwirl S1 sets a new benchmark for offshore windpower.

About SeaTwirl S1

SeaTwirl deployed the 30kW floating wind turbine off the coast of Lysekil in July 2015. S1 has been connected to the grid and tested according to plan since its deployment.

The project was implemented by a small and ambitious group on a limited budget. SeaTwirl S1 is one of the very few floating wind power projects in the world to have been launched and operated for a longer period of time. SeaTwirl S1 has withstood harsh weather conditions, autumn and winter storms reaching hurricane wind speeds. This shows how robust our design is.

Potential customers

Although the S1 is a small 30-kW turbine, it offers a practical solution in a number of situations.

Test platform for energy companies

The S1 offers energy producing companies an attractive test platform for offshore wind power.

Alternative to diesel generators in remote areas

In remote areas that are off-grid or prone to power outages, the SeaTwirl S1 is an interesting alternative.

Organisations wanting to go green

Many organisations are interested in reaping the benefits of renewable energy.
“SeaTwirl with its simplicity and cost-effectiveness will become a real challenger on the offshore wind power market”

Advantages of SeaTwirl

  • Simple, robust design with a minimum of breakable moving parts, which means less downtime and more output
  • Provides easy access to parts requiring maintenance
  • Stable structure due to the low centre of gravity
  • The water supports the weight of the wind turbine which reduces stress on the bearings
  • Scientific reports show that vertical axis wind turbines have a high structural limit and can be built larger than horizontal-axis wind turbines.

Areas of use

  • Small-scale energy production
  • Islands and remote locations
  • Fish farms
The SeaTwirl S1 is easily accessed when maintenance is planned since all major components are at sea level.
