Evaluation of Container Ship Maneuvering Characteristics from View Point of Ship Handling Ability

Abstract

If the ship handling ability can be evaluated, the safety of navigation would be assured. Generally, the handling ability has not been defined yet. In this paper, the handling ability is called as the handlability. In order to define the ship handlability, we have been developing a standard evaluation method by the basic of difficult situation. The difficult situation is the approaching jetty. The handlability includes both of ship maneuverability and human characteristics. Numerical simulations are carried out to estimate the ship maneuverability. By comparing between numerical simulations results and mariner handling results, we evaluate the ship maneuvering characteristics under control of human. These evaluations enable us to define standard criteria on the handlability. In this paper, the study of a container vessel is introduced.
