Full-scale measurement on the service performance for the 499 G. T. Coastal Cargo Ship 'Shoyo-Maru' has been conducted and the following conclusions are obtained :1)The comparison of the statistical and spectrum analysis shows that the Raleigh distribution is also valid for the evaluation of the ship responses in the coastal waves.2)Long-term distributions of ship responses in coastal waves can be estimated by using the same method for the ocean going ship.3)The variation of ship speed, winds and ship responses with the sea areas and seasons has been shown.4)The speed loss is considerably affected by the current and the effect of wind is quite small.5)The fuel consumption can be approximately estimated from the measured data of ship responses.6)The distribution of acceleration in the cargo hold can be estimated from the measured data of ship responses in the bridge.7)The distribution of acceleration in the cargo hold can be qualitatively estimated from the ship motions evaluated by the strip method along with the wave data shown in the Log-book.8)The operation diagram for the master considering maximum acceleration in the cargo hold and the flowchart for operation to prevent cargo spill has been shown.

499 G服务性能的全尺寸测量。T.对沿海货船“Shoyo-Maru”进行了研究，得出以下结论：1）统计分析和谱分析的比较表明，罗利分布同样适用于计算船舶在近岸波浪中的响应; 2）对于远洋船舶，同样的方法也可以计算出船舶在近岸波浪中的响应的长期分布; 3）船舶速度的变化，4）航速损失受海流影响较大，风的影响很小根据船舶响应的实测数据，可以近似估算出燃油消耗量。6）根据驾驶室内船舶响应的实测数据，可以估算出货舱内加速度的分布。7）根据沿着的波浪资料，用条带法计算船舶运动，可以定性地估计货舱内的加速度分布。8）给出了考虑货舱内最大加速度的船长操作图和防止货物溢出的操作流程图。
