Norsepower, together with project partners Maersk Tankers, Energy Technologies Institute (ETI) and Shell International Trading and Shipping, have announced the trial results of two 30m Norsepower Rotor Sails onboard the product tanker 'Maersk Pelican.'

The Rotor Sails were installed on the vessel in August 2018. Aggregated total fuel saving from 1 September 2018 to 1 September 2019 was confirmed to be 8.2% over a baseline figure established prior to installation. This is equivalent to approximately 1,400 tonnes of CO2. Lloyd’s Register’s (LR’s) Ship Performance Group analysed and validated the performance data during the project to ensure an impartial assessment.

“During the one-year trial period on Maersk Pelican, crew and operators have reported positively on the usability, safety and performance of the Rotor Sails in all conditions,” said Tommy Thomassen, CTO Maersk Tankers. “Maersk Tankers and the industry have developed and tested a number of technological solutions, which contribute to reducing fuel consumption and associated emissions. 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.”

Dr Chris Craddock, Technical Advisory & Ship Performance Manager, Lloyd’s Register, said: “As the independent performance verifier of the Norsepower Rotor Sail, LR sees our role as a trusted independent expert, assessing the return on investment for new technologies that address the challenges of decarbonisation. Wind power technologies are part of the solution, and the Norsepower Rotor Sail has proven itself to save fuel and reduce emissions.”

Tuomas Riski, CEO said: “With the Maersk Pelican, there are three vessels in daily commercial operation using Norsepower’s Rotor Sails. Each of these cases represents a very different vessel type and operational profile, demonstrating the widespread opportunity to harness the wind through Rotors Sails across the maritime industry.”

In a simulation model, Norsepower has shown that the current Rotor Sails operating in global average wind conditions of all shipping routes yields a savings potential up to 12% on fuel and emissions. Based on the same simulation model, Norsepower estimates that applying Rotor Sail technology to the global tanker fleet would reduce annual CO2 emissions by more than 30 million tonnes.

“Through future advances in technology we believe the Rotor Sails can contribute even more as one of the solutions to tackle CO2 emissions within the shipping industry,” said Riski.

Darryl Hylands, Programme Manager, HDV, Energy Technologies Institute (ETI) said: “This is one of ETI’s large scale demonstration projects aiming to accelerate low carbon technologies. Successfully demonstrating this technology at scale shows its capability to significantly reduce fuel costs and environmental impact of the shipping industry. On certain routes during the trial the vessel achieved fuel savings way beyond the average of 8.2% even with average wind conditions. There is a clear potential to achieve higher fuel savings, and hence CO2 savings, on routes with more favourable wind conditions, which further improves the commercial viability of the technology.”
