A bespoke and economical design for a rotor to work as wind-assisted propulsion device has been developed. Utilising the various skills available in the UK, the product will be manufactured and supplied to various domestic and international ships.

​Presently, typical rotor installation costs for a vessel are understood to be around 1 million to 3 million USD depending on the number of rotors, and most of the installations are subsidised by government fundings. It is expected that bespoke designs of rotors can reduce the price by 30% to 50%, depending on the specific vessel. The TRL of this product is 2.
