the addition of Norsepower’s technology, the vessel will further reduce its emissions, fuel burn, and fuel costs; reducing carbon emissions by circa 900 tonnes annually; equivalent to cutting 300 tonnes of LNG fuel per year.


Preparations for the retrofit are underway, with the installation scheduled to take place during Q2 of 2018. Viking Grace is set to be retrofitted with one medium-sized Norsepower Rotor Sail unit that is 24m in height and 4m in diameter.

TANKER In a project co-funded by a consortium including Maersk, Shell, and the UK’s Energy Technologies Institute (ETI), a Maersk P-class 109,647 deadweight tonne (DWT) oil products tanker, will be retrofitted with two 30m tall and 5m diameter Norsepower Rotor Sails, which combined are projected to reduce average fuel consumption on typical global shipping routes by more than 10%.


This project is an important break- through for the tanker market which is considered to be one of the major markets where Rotor Sails provide a competitive solution for improving the energy efficiency during operation.

FUTURE VISION


Norsepower sees an excellent potential for the growth of the Rotor Sail market. The company has been extremely satisfied with the fuel savings results achieved to date. Going forward, Norsepower plans to ensure continuous optimisation of its technology in order to further cut fuel consumption, and in so doing deliver greater fuel cost savings. In addition, pending sulphur regulations in 2020 – which are highly anticipated to see fuel costs rise – Norsepower’s technology will further enhance savings in dollars and cents terms.


CONCLUSION


Norsepower is proud to be the first company to utilise renewable energy on a large commercial vessel while it is in motion. As the company continues to expand commercially, it will be able to develop larger Rotor Sails which will equate to more fuel savings for shipowners and cargo owners paying for the fuel. The ability to harness the wind as an additional power source to enable a reduction in fuel consumption is a natural next step for the maritime transport industry as it seeks to remain cost-efficient and meet environmental regulations.
