Abstract

Vessel berthing is defined entire processing which vessel is closing next to a pier in port or harbour, it is known as the most difficult and complex process in the total ship operating. Vessel berthing utilizes a main propulsion to main power source and is supplied with side thruster or tugboat. A modernized vessel or a special purpose vessel utilizes an azimuth thruster to vessel berthing more intelligently even if the vessel has '0' speed. However, most of the normal ships are less active when berthing by the limitation of fixed direction propulsion system. It has been a long time since the automation of port management system and the modernization of vessel had been started and operated. However, it is a fact that the vessel berthing has not been exceeded the primitive level until the present. Even if the vessel is equipped with high-tech equipments to help when berthing, there are profound technical difficulties for the safely automatic vessel berthing to the final step. For example, in the case of the system developed by CAVOTEC company, it is dependent on the berthing-support system installed on the port to berth of final operating. This study purposes to overcome the limit of vessel berthing and to develop technology for making alternative environment which carry out berthing more safety and faster. In other words, we would like to develop a technology for building a more reliable berthing support system in place of the classical ship berthing system using a tugboat. This study proposes a robust system that can quickly and safely berth using a damper and a winch on the port without using the vessel propulsion unit. This is to establish a construction of vessel berthing system by damper-winch cooperation, so that it is vessel berthing perfectly without support of a tugboat. We plan to evaluate and verify the effectiveness of this berthing system through a simplified model ship and quay (including damper-winch) water tank experiment.
