Retrofitting of two 30 m tall by 5 m diameter Norsepower Rotor Sails on a 109,647 dwt vessel will take place during H1 2018, with test through until the end-2019. Average fuel savings of 7-10% are expected on normal routes, says the teaming.
The project is majority funded by the UK’s Energy Technologies Institute (ETI) with contributions from Maersk Tankers and Norsepower. Shell will act as project coordinator.
The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor – a spinning cylinder that uses the Magnus effect to harness wind power to propel a ship. When wind conditions are favourable, the main engines can be throttled back, providing a net fuel cost and emission savings,
Norsepower ceo Tuomas Riski said he hoped the trial would “open up the market for our technology to a larger number of long-range product tanker vessels – paving the way for ship fuel efficiencies, and ultimately reducing emissions, including greenhouse gases.”
