摘　　要：青岛海业油码头水域是不均匀流场。为提高VLCC靠泊和系泊该码头的安全性,使其靠泊和系泊过程所受外力皆在可控范围之内,减少不必要的航行、靠泊和系泊风险,有必要对船舶航行、靠拢和系泊过程中船舶所受的水流力进行量化。根据流体力学的原理,得出船舶在海业油码头水域不均匀流场的不同位置、不同时段所受的水流力,以及由此导致的船舶运动变化,进而推导出船舶在相应的拖轮、系缆配置下最佳的靠泊窗口期。运算量化结果表明,大潮汛期间,船舶入泊的窗口期为高潮前1小时和高潮后40分钟之间;系缆和系泊期间,6条拖轮中的5条应置于船首外档,全力顶推,防范船首受内开流的作用离开码头。In order to improve the safety of VLCC berthing and mooring at Qingdao Haiye oil terminal,ensure the external forces during berthing and mooring are all under control,reduce the risk of unnecessary navigation,berthing and mooring,it is necessary to quantify the flow forces on the ship during berthing,and mooring.Based on the principle of fluid mechanics,the different positions of the uneven flow field,the flow forces at different time periods,and the resulting changes in the motion of the ship in the waters of the marine oil terminal are obtained Furthermore,the optimal berthing window period of the ship under the corresponding tugboat and mooring line configuration is derived.The numerical results show that the window period for ships to berth is between 1 hour before and 40 minutes after the high tide,and 5 of the 6 tugs are placed in the outermost berth during berthing and mooring,push hard to prevent the bow from leaving the dock under the action of open current.
