Not Sailing

Norsepower Oy’s Rotor Sail solution has received the first-ever type approval design certificate granted to an auxiliary wind propulsion system on board a commercial ship.

The type approval from DNV GL was issued after a design assessment of Norsepower’s 30-meter by five-meter Rotor Sail, two of which have been installed on board the Maersk Pelican LR2 tanker. The certification means that vessels operating Norsepower’s Rotor Sails are technically capable of safely navigating “all operational and environmental situations.”

The system has already been installed on three vessels and has achieved over 35,000 hours in operation and has delivered independently verified fuel savings with potential of up to 20 percent. Last year, Viking Line installed an 80-foot Norsepower system on the cruise ferry Viking Grace. Read on.
