Norsepower’s auxiliary wind propulsion system Rotor Sail Solution has received a design type approval certificate from DNV GL.
DNV GL issued the approval assessing a design of Norsepower’s 30m by 5m Rotor Sail, two of which have been installed on-board the Maersk Pelican LR2 tanker.
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.”
Norsepower’s Rotor Sail Solution fuel-saving technology supports the decarbonisation of the shipping industry.
The solution, which has already been installed on three vessels, has achieved more than 35,000 hours of operation and delivered independently verified fuel savings with the potential of up to 20%.
DNV GL technical director and Ship Classification director Geir Dugstad said: “To help reduce shipping’s environmental impact, we will need many different fuel and technology options, which is why we were very pleased that Norsepower asked us to be part of this innovative wind propulsion project.”
