摘　　要：为满足钦州港未来20万吨级集装箱船进出港及靠离泊作业安全性和可靠性要求,依托大榄坪港区东航道及9#泊位建立船舶操纵数学模型。通过模型计算反演船舶进出港以及靠离泊的有效航迹,为航道及回旋水域安全通航提供建议。结果表明:东航道现有10万吨级双向通航航道可满足未来20万吨级集装箱船在6级风况下单向通航的需求,航道水深需进一步疏浚至-16.3 m,船舶可以乘潮进出港;进港时,南段转三墩段的建议航速为9 kn,参考舵角15°;三墩段转大榄坪段,建议航速为7 kn,参考舵角20°。在靠岸风和涨潮流共同作用下,船舶回旋的航迹幅度较大,水域沿水流方向尺度需由原先的790 m扩展为1200 m。In order to meet the safety and reliability requirements of the future 200,000 DWT container ships entering and leaving the port,berthing and unberthing operation in Qinzhou Port,a ship maneuvering mathematical model is established based on the east channel and the 9#berth in the Dalanping port area.The effective tracks of ships entering and leaving the port and berthing and unberthing are analyzed through model calculation,and the safe navigation conditions of channel and whirling waters are concluded.The analysis results reveal that the current 100,000 DWT two-way navigable channel in the east channel of Qinzhou Port can meet the requirements of one-way navigable channel for 200,000 DWT container ships in the future under level 6 wind conditions,and the channel water depth needs to be further dredged to-16.3 m to ensure that ships can enter or leave the port while taking advantage of the tide.Through the navigation process simulation,it is suggested that when the ship enters the port,the speed of turning from the south section to the Sandun section should be controlled at 9 knots,and the rudder angle suggested to be 15°;while the speed of turning from the Sandun section to the Dalangping section should be controlled at 7 knots,and the rudder angle suggested to be 20°.Under the combination of shore wind and rising tide current,the ship s departure turning track has an unexpected range,and the scale of turning water area along the flow direction needs to be expanded from 790 m to 1200 m.
