Wind propulsion developer Norsepower says it has received a new order from an as yet unnamed European shipowner for two of the largest Rotor Sail units to be retrofitted to a cargo vessel.

Preparations for the fitting will take place in 2020, at which time Norsepower expects to be able to release details of the vessel and owner concerned. Installation is scheduled for Q4 2020. The new order follows successful trial results of two Rotor Sails onboard the Maersk Tankers’ product tanker, Maersk Pelican.

The Norsepower Rotor Sail is a modernised version of the Flettner rotor – a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship. It is claimed to be the first data-verified and commercially operational auxiliary wind propulsion technology for the global maritime industry. When wind conditions are favourable, it enables the propulsion system to be throttled back, reducing emissions, while maintaining propulsion power to keep to speed and voyage time.

Norsepower says that with growing international and public pressure on the maritime industry to move towards decarbonisation, the ability to harness the wind to generate thrust, reduce fuel consumption and emissions, is a natural next step for the maritime transport industry. In addition to its very real financial and environmental benefits the company estimates that its technology would be able to achieve a carbon emissions reduction of around 10%-15% per ship, which would equate to a circa 5% reduction in carbon emissions for the global maritime fleet.

In addition to this announcement, Norsepower’s Rotor Sails have been installed onboard three vessels, including Bore’s M/S Estraden 9,700 dwt ro-ro carrier, Viking Line’s M/S Viking Grace, an LNG–fuelled cruise ferry, and Maersk Tanker’s 110,000 dwt Maersk Pelican. Norsepower has recently started a delivery project of a Rotor Sail to a hybrid ferry owned by Danish shipping company Scandlines.
