Abstract
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.关键词
