SeaTwirl has a unique solution for floating wind power. Each part of the wind turbine is a proven technology. Most of the floating concepts that are being tested are of the traditional type of horizontal-axis turbines mounted on some form of floating structure. There is much to suggest that vertical-axis wind turbines are more suitable for the marine environment than the traditional horizontal-axis wind turbines. The simplicity of the design and low centre of gravity are the great advantages. Few moving parts, which are easily accessible because they are located close to the water surface, lowering the total operation cost of the wind turbine. Service and maintenance costs are also minimised, which is a key consideration for wind turbine owners. SeaTwirl's great advantages are its simple, robust and cost-effective design that also leads to lower service and maintenance costs compared with other traditional horizontal axis wind turbines. SeaTwirl will deliver a competitive solution for future sustainable power generation which is why we believe in a positive future for Sea Twirl.
