Norsepower Rotor Sails Issued First-Ever Design Type Approval for Onboard Wind Propulsion

Finnish clean technology group Norsepower announced Tuesday 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 leading ship classification society DNV GL was issued in February 2019 after a design assessment of Norsepower’s 30-meter by 5-meter Rotor Sail, two of which have been installed onboard the Maersk Pelican LR2 tanker.

Installation of two Norsepower Rotor Sails onboard ‘Maersk Pelican’

Norsepower Oy Ltd., together with project partners Maersk Tankers, Energy Technologies Institute (ETI) and Shell Shipping & Maritime, recently announced the installation of two Norsepower Rotor Sails onboard ‘Maersk Pelican’, a Maersk Tankers Long Range 2 (LR2) product tanker vessel. The Rotor Sails are Flettner rotors; large, cylindrical mechanical sails that spin to create a pressure differential - called the Magnus effect - that propels the vessel forward. The Rotor Sails will provide auxiliary wind propulsion to the vessel, optimising fuel efficiency by reducing fuel consumption and associated emissions by an expected 7-10% on typical global shipping routes. The Rotor Sails are the world’s largest at 30 metres tall by five metres in diameter and were installed on the product tanker vessel in the port of Rotterdam. The first voyage with the Rotor Sails installed will commence shortly.

Testing begins on first tanker utilising wind propulsion
