摘　　要：为准确评估开敞式LNG码头在设计船型和海况下的作业可靠性,本文基于物理模型试验对某LNG项目的船舶系泊动力响应进行分析,并根据试验结果评估系泊方案的可行性。研究结果表明:在设计海况作用下,当波浪呈30°入射时,2万m^(3)LNG船舶横摇运动量不满足PIANC推荐值要求,17.5万m^(3)LNG船舶在艉顺风作用下,纵移运动量超过PIANC推荐值;在缆力方面,17.5万m^(3)LNG船舶在11 s周期顺浪叠加艉顺风作用时,艏倒缆不满足系泊安全条件,因此艏艉倒缆应视安全储备需求增加一定数量。In order to accurately evaluate the operation status of an open LNG berth under the design ship type and sea conditions,the dynamic response caused by ship mooring is analyzed by using physics model based on a LNG project,which may verify the mooring plan applicable or not.The results show that the rolling motion of a ship accommodating for 20000 m^(3) LNG does not reach the recommended value by PIANC subject to 30°incidence angle of wave under the design sea condition.However,the longitudinal motion of a ship for 175000 m^(3) LNG is higher the above recommended value under the action of stern downwind.By considering ship mooring force,ship bow inverted cable does not satisfy safe mooring requirements subject to a 175000 m^(3) LNG ship under the condition of 11 s period of wave following combined with stern downwind.Therefore,the inverted cables at ship bow and stern shall be increased by a certain amount according to the safety reserve.
