In this study, the berthing and unberthing performances of a single-propeller and single-rudder inland container ship with a flapped rudder and bow thruster were investigated using free-running model tests. A navigation method was used for the tests to adjust the bow thruster, so that the heading remained parallel to the pier and the ship berths or unberths while sailing in oblique conditions. As a result, the proposed method enables the target ship to berth or unberth in shallow water with \(h/d=1.5\), where h is the water depth and d is the ship draft. Such a free-running test using the navigation method is useful for evaluating the berthing and unberthing performance of single-shaft ships with a bow thruster. In addition, a bow thruster impeller revolution controller was incorporated into the maneuvering simulation model proposed by the authors, and berthing calculations were performed. The calculation results were compared with free-running test results for validation. These results are consistent with the free-running test results with practical accuracy.

本研究采用自由运行模型试验研究了带有扑翼舵和艏侧推器的单螺旋桨单舵内河集装箱船的靠泊和离泊性能。试验采用导航法调整艏侧推器，使船舶在倾斜条件下航行时，航向与码头和靠泊位保持平行。因此，该方法使得目标船能够在\(h/d=1.5\)的浅水中靠泊或离泊，其中h是水深，d是船舶吃水。这种使用导航方法的自由运行试验对于评估带有艏侧推器的单轴船舶的靠泊和离泊性能是有用的。此外，作者提出的操纵仿真模型中加入了艏侧推叶轮转速控制器，并进行了靠泊计算。将计算结果与自由运行的测试结果进行比较以进行验证。这些结果与自由运行的测试结果一致，具有实用的准确性。
