Outline of Final Research Achievements

Using the model ships of KCS (container vessel) and KVLCC2 (tanker), captive model tests were carried out to measure hydrodynamic forces (lateral force and yawing moment) acting on hulls when the ships run in the proximity of a bank wall. The influence of water depth, the width of narrow waterway, drift angle and the distance between a ship and a bank wall were clarified. Based on the measured hydrodynamic forces, approximate formulae for estimating lateral force and yawing moment with the above mentioned parameters were proposed. Furthermore free running model tests were performed to compare with simulation results, then simulation results were validated by comparing with the measured trajectories and other parameters.
