THE DAMAGE INFLICTED BY SHIPS WITH BULBOUS BOWS ON UNDERWATER STRUCTURES
Most existing port structures were designed before bulbous bows came into frequent use, and many of their underwater structures are therefore extremely vulnerable to damage from such bows. Accidents may not be frequent, but can easily lead to fatal consequences and to very high costs for repair and for disturbances to operations. This report discusses the interface between bulbous bow ships and the various types of docks that must berth them. It also presents the results of a survey of actual bulbous bow damage that has occurred, and discusses the operational aspects of bulbous bow ships that are in a harbor and docking. Based on the survey, it is concluded that no general trend is apparent and that accidents involving bulbous bow ships and underwater structures are likely to continue to occur. Nevertheless, there are measures that can lead to a higher degree of safety without jeopardizing the commercial efficiency of ports. Recommendations regarding such measures are listed, separately, for port managers and harbor masters, ship captains and pilots, port designers, and shipbuilders.
