DNV GL proceeded to the type approval on 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 certification highlights that vessels operating Norsepower Rotor Sail Solution are safe to navigate all operational and environmental situations.

Norsepower’s Rotor Sail Solution is a proven, low-maintenance, easy to use, and reliable fuel-saving technology, supporting the decarbonisation of the shipping industry.

The technology has already been installed in three vessels and has accomplished more than 35.000 hours in operation. In the meantime, the technology resulted to saving up to 45.000 tonnes of CO2 during the operation.

The solution has delivered independently verified fuel savings with potential of up to 20%.

Tuomas Riski, Norsepower CEO, commented that they are proud to be the first company to have type approval granted to a wind propulsion system on a commercial vessel.

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.

... Geir Dugstad, Director of Ship Classification and Technical Director at DNV GL, added.

Concluding, Norsepower Oy Ltd., is the leading clean technology and engineering company pioneering modern auxiliary wind propulsion for the global maritime industry.
