WebThe present study proposes an innovative and efficient methodology for the hydrodynamic optimization of the bulbous bow form of a large container ship which accounts for multiple operating conditions, resulting in a multi-dimensional, multistoried and wide-ranging ship optimization design philosophy. Bulbous bows have been found to be most effective when used on vessels that meet the following conditions: The waterline length is longer than about 15 metres (49 ft). [4] The bulb design is optimised for the vessel's operating speed. [5] See more A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, … See more Bulbous bows embody the following defining characteristics: • Length-wise shape • Cross-section • Length of forward projection See more • Axe bow § LEADGE-bow See more The effect of the bulbous bow can be explained using the concept of destructive interference of waves: A conventionally shaped bow causes a bow wave. A bulb alone forces the water to flow up and over it forming a trough. Thus, if a bulb is … See more Towing tests of warships had demonstrated that a below-water ram shape reduced resistance through the water before 1900. … See more Some warships specialised for anti-submarine warfare use a specifically shaped bulb as a hydrodynamic housing for a See more
