Norsepower Oy Ltd., the leading clean technology and engineering company pioneering modern auxiliary wind propulsion for the global maritime industry, has announced that its innovative Rotor Sail Solution has received the first-ever type approval design certificate granted to an auxiliary wind propulsion system onboard a commercial ship.

The type approval from DNV GL was issued in February 2019 after a design assessment of Norsepower’s 30-metres by 5-metre Rotor Sail, two of which have been installed onboard the Maersk Pelican LR2 tanker. The landmark certification means that vessels operating Norsepower’s Rotor Sail Solution are technically capable of safely navigating ‘all operational and environmental situations’.

Norsepower’s Rotor Sail Solution is a proven, Flettner Rotor system, supporting the decarbonisation of the shipping industry. It has already been installed on three vessels and has achieved over 35,000 hours in operation, saving more than 4,500 tonnes of CO2 in the process. The solution has delivered independently verified fuel savings with potential of up to 20%.

Commenting on the type approval, 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 onboard 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.”
