A STUDY ON HULL FORM DEVELOPMENT OF A 37,000 DWT BULK CARRIER

An effort was made to develop a power efficient, handy-sized bulk carrier through series tests. Different theories and empirical methods were applied to obtain the hull form with the best resistance and propulsion characteristics. Emphasis was placed on minimizing linear wave profile and wave breaking at the bow. The flow visualisation test was employed to improve the flow around the hull surface, especially the stern. A wake-adapted propeller was designed to reduce propeller induced vibration to a low level. The hull form obtained using this procedure showed a DHP saving of 14% compared with the parent ship.
