The gain in propulsive efficiency using a large diameter propeller rotating slowly is perhaps the simplest and most robust way of improving the fuel economy of a ship. In order to take the advantage of this approach small workboats (e.g. tug boats, fishing vessels etc.) operate in service with a significant increase of aft draught and hence resulting "inclined keel" configuration can be observed. Although large vessels sometimes operate with stem trim to improve their propulsive performance, it is rare to see a such vessel purposely built with an inclined keel feature to fit a large diameter propeller for power saving. This paper explores the application of the inclined keel configuration to a 3600TEU container vessel. The aim of the research is to fit an 11 % larger diameter propeller (and hence resulting 17.5 % lower rpm) to gain further power saving over the similar size basis container ship with conventional "level keel" configuration. The paper also investigates the knock-on effects of the inclined configuration on the other hydrodynamic performances including cavitation, hull vibration, seakeeping and manoeuvring of the vessel in a comparative manner. ©2006: Royal Institution of Naval Architects.
