SUPPLIER of wind propulsion systems Norsepower has signed a framework agreement with Offshore Technology Development, Keppel Offshore & Marine’s technology arm specialising in the provision of critical equipment which supports the offshore oil and gas, marine, and offshore wind industries.

Under the agreement, OTD can assist to provide the initial survey, design and engineering works, and organise the equipment installation for Norsepower’s rotor sails. Norsepower will deliver project management, delivery, and installation supervision to support smooth installation, servicing and warranty support of rotor sails.

The company’s say it’s a “significant step” in fully commercialising the rotor sail which is capable of achieving, on average, between 5% and 20% reductions in carbon and other emissions, as well as fuel and fuel costs in suitable conditions.


The Norsepower Rotor Sail Solution is the first third-party verified and commercially operational auxiliary wind propulsion technology for the maritime industry. The solution is fully automated and detects whenever the wind is strong enough to deliver fuel and emission savings, at which point the rotor sails start automatically.

Norsepower has completed five installations to date and is due to complete its sixth installation of five tilting rotor sails on a bulker during the first half of this year.
