Norsepower Rotor Sail™ is especially suitable for tankers due to its ATEX-compliant design and available deck space. Below, you can find information about our reference ships.

Epanastasea (ex Timberwolf, ex Maersk Pelican)

In partnership with Maersk Tankers, The Energy Technologies Institute (ETI), and Shell Shipping & Maritime, two Norsepower Rotor Sails™ were installed onboard the Maersk Pelican in August 2018. They underwent testing and data analysis at sea until the end of 2019. Independent measurements conducted by Lloyd's Register confirmed savings of 8.2% during the first year of operation.

Two 30m x 5m Norsepower Rotor Sails™ are expected to reduce average fuel consumption on typical global shipping routes by 7 – 10%.

“This project is breaking ground in the product tanker industry. While the industry has gone through decades of technological development, the use of wind propulsion technology onboard a product tanker vessel could take us to a new playing field.”

The Alcyone is a 50’000 dwt, 2022 built, French flag tanker - chartered by global energy company TotalEnergies. It transits between South Korea and French Polynesia.   It was retrofitted in 2024 with two 35 m x 5 m Norsepower Rotor Sails™️, delivered from Norsepower’s new production hub in China. Based on existing data and projections, Norsepower estimates that the ship can achieve at least 8% fuel consumption and emission reductions on its route.
