Rolls-Royce has won a contract to supply its Promas Lite propulsion system to the Norwegian ship owner Hurtigruten for their cruise ship MV Richard With. Propeller efficiency improvement for the ship is estimated to be between 11-14 per cent at 15 knots. MV Richard With: Photo courtesy the owners Promas Lite is a version of the Rolls-Royce Promas integrated propeller and rudder system which is designed specifically for vessels already in service. It is well known that with advances in propeller design, propeller blade changes, or the fitting of new propellers, can have a significant effect on propulsive efficiency, fuel consumption and, therefore, emissions. With Promas Lite these improvements can be maximised, as the propeller and rudder are treated as a complete system, and further increases in efficiency can be achieved with improved manoeuvrability for only a small increase in cost. First, extensive modelling work is carried out at the Rolls-Royce Hydrodynamic Research Centre in Sw... [More]
