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.

船舶进出港的安全管理是船舶安全管理的重要内容。首先，本文成功地观测到了涌浪中的船舶运动。结果表明，在港内靠泊作业中，以及在港门口处，均出现了困难。通过对观测数据的分析，从数值上了解这些困难。本文首先建立了船舶在涌浪中进出港运动的数值模拟模型。其精确度似乎足以重现某些观测到的船舶运动情况。此外，有必要定义新的靠泊作业难度评价参数。提出并验证为“靠泊功能难”。“该函数可以定量评估操作难度，这一点在港口安宁中应该考虑。
