SeaTwirl's S1: A small-scale workhorse
30 kW
Installed in 2015
S1 has withstood the test of time and weather.
The Concept Model
S1 sets a new benchmark for offshore windpower.
About 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. 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. S1 has withstood harsh weather conditions, autumn and winter storms reaching hurricane wind speeds. This shows how robust our design is.
Potential customers
Although S1 is a small 30-kW turbine, it offers a practical solution in a number of situations.
Test platform for energy companies
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, S1 is an interesting alternative.
Organisations wanting to go green
Many organisations are interested in reaping the benefits of renewable energy.

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
