边际油田开发过程中，有时将储（运）船舶停靠在导管架平台内，在导管架上布置横、纵护舷以约束储运船舶。采用物理模型试验方法，研究了随机波浪作用下，船体在固定护舷约束下的运动和动力响应问题。试验结果表明：原型3000 t级储运船舶，当船侧与横向护舷间隙为500 mm、纵向护舷间隙为零时，船舶各运动分量较为自由，未见甲板上浪情况。单个横向护舷最大吸收能量为1465 kJ，纵向护舷最大吸收能量为745 kJ。随着船侧与护舷间隙减小，船舶各运动分量运动受到限制，不同程度的出现甲板上浪现象，护舷吸收能量相比于间隙为500 mm情况有所减小。当考虑船舶运动及甲板上浪时，船体与护舷间应适当留有间隙；当考虑护舷及船体碰撞安全时，应适当减小间隙。

In the process of marginal oil field development, sometimes the vessels are docked in a jacket plat?form and horizontal and vertical fenders are installed in the jacket in order to restrict the vessels. The vessels′re?sponse of motion and power in restraint of fixed fenders was researched in the function of random waves in the way of physical model test. The model test result shows that each component motion of the prototype vessel with 3 000?ton storage capacity was unrestrained and the green water was not found when the gap between the vessel and hori?zontal fenders was 500 mm and the gap between the vessel and vertical fenders was 0. The maximum energy absorp?tion of single horizontal fender was 1 465 kJ and 745 kJ for single vertical fender. The motion component of vessel was limited and there was some green water on deck to various degrees when the gap between fenders and the vessel was reduced. Fenders absorbed less energy compared with the case where gap between fenders and vessel was 500 mm. when the ship motion and green water are considered, it is suggested to keep appropriate gap between fenders and the vessel;when the safety of collision between fenders and the vessel are considered, it is suggested to reduce the gap appropriately.
