Abstract
An energy-saving device (ESD) is used to obtain energy lost and convert additional energy to a propulsive coefficient. This research uses PBCF as an energy-saving device that is attached to an MP687 propeller and a Japanese bulk carrier a hull. Method for solving this research using the open water test and self propulsion method based on computational fluid dynamic (CFD). Added propulsive coefficient obtained from PBCF conventional can reach up to +1.52 %. PBCF with duct make smaller added for propulsive coefficient caused by duct splitting fluid flow from the propeller. PBCF with duct can increase propulsive coefficient up to +0.48 %. PBCF can eliminate a strong hub vortex at propeller MP687 and its ba e good choice for the increased propulsive coefficient of the ship.
