Norsepower Oy Ltd. a Finnish clean technology and engineering company, in partnership with Maersk Tankers, The Energy Technologies Institute (ETI), and Shell Shipping & Maritime, will install and trial Flettner rotor sails onboard a Maersk Tankers-owned vessel. The project will be the first installation of wind-powered energy technology on a product tanker vessel, and will provide insights into fuel savings and operational experience. The rotor sails will be fitted during the first half of 2018, before undergoing testing and data analysis at sea until the end of 2019. Maersk Tankers will supply a 109,647-deadweight tonne (DWT) Long Range 2 (LR2) product tanker vessel which will be retrofitted with two 30m tall by 5m diameter Norsepower Rotor Sails. Combined, these are expected to reduce average fuel consumption on typical global shipping routes by 7-10%. 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, and provide operational and terminal / port consultancy to the project team, while Maersk Tankers will provide technical and operational insight. 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. Each Rotor Sail is made using the latest intelligent lightweight composite sandwich materials, and offers a simple yet robust hi-tech solution. When wind conditions are favourable, the main engines can be throttled back, providing a net fuel cost and emission savings, while not impacting scheduling. Independent experts will analyse the data gathered from the project before publishing technical and operational insights, and performance studies. (Source: Norsepower)
