Improving propulsive efficiency is the key in reducing fuel burn, and this simple modification allows vessels already in service to benefit from Promas efficiency gains. There are three areas of modification – welding a prefabricated bulb to the existing rudder, bolting a hubcap to the propeller, and fitting a new propeller or reblading the original. Promas Lite installations on vessels operating significantly off their original design speed should provide an efficiency improvement in the region of 5 – 15 per cent. Installation is normally 7-10 days and the payback time can be under two years.
