The certification means that vessels operating the Rotor Sail Solution will be able to safely navigate operational and environmental situations.

Norsepower CEO Tuomas Riski said: “We are very proud to be the first company to have type approval granted to an auxiliary wind propulsion system on-board a commercial ship. Having a type approval design certificate is very important to us.

“Clearly, it provides shipowners, operators, and charterers with a level of assurance when investing in the Rotor Sail Solution, but in the long term, it removes yet another hurdle to the realisation of renewable wind energy propulsion systems at a scale that supports shipping’s transformation to a low-carbon transport sector.”
