| Research Abstract |
It is very important to maintain the safety when ships enter into or depart from harbors. At first, ship motions are successfully observed in swells in this study. It is shown that the difficulty is occurred during the berthing operation inside harbor as well as the harbor entrance. Observed data are analyzed to know these difficulties numerically. Numerical simulations of ship motions in swells during the entering and departing are newly constructed at first. The accuracy seems to be enough to reproduce against some cases of observed ship motions. Moreover, it is necessary to define the new evaluation parameters about the difficulty of the berthing operation. It is proposed and verified as the "Difficulty of Berthing Function." The function can evaluate the operational difficulty quantitatively, this point should be considered in the harbor tranquility.
