Two 30-metre tall Rotor Sails installed match initial fuel and associated CO2 saving expectations of 8.2%.
This is equivalent to approximately 1,400 tonnes of CO2. The savings were confirmed by comparing detailed performance information to a baseline established with full scale measurements and computational analysis done for the vessel prior to the Rotor Sail installation.
Independent experts from Lloyd’s Register's (LR's) Ship Performance Group have analysed and validated the performance data during the project to ensure an impartial assessment. In addition, technical and operational insights for performance studies will also be published.
In a simulation model, Norsepower shows that with the currently installed Rotor Sails operating in global average wind conditions of all shipping routes, yields a savings potential up to 12% on fuel and emissions, including CO2. Based on the same simulation model, Norsepower estimates that applying Rotor Sail technology to the entire global tanker fleet would reduce annual CO2 emissions by more than 30m metric tonnes, which corresponds to emissions of about 15m passenger cars.
Tommy Thomassen, CTO, Maersk Tankers, said "We see wind technology as one of the technologies that can give us a real breakthrough in reducing CO2 and help us achieve our emission-reduction target of 30% by 2021. We will closely follow the development around the financial and commercial viability of the technology for potential future installations on some of our other larger vessels, while we have decided that Maersk Pelican will continue to sail with the Rotor Sails."
