摘　　要：为研究码头受限水域大型液化天然气(Liquefied Natural Gas,LNG)船舶失控下的拖船安全部署,保障港口码头作业安全,研究采用计算流体力学(Computational Fluid Dynamics,CFD)分析方法,基于风流干扰模型,通过模拟不同工况下大型LNG船舶的漂移过程,计算水动力学参数,确定应急拖船部署策略。以温州小门岛水域为案例研究对象,重点分析Q-max LNG船舶在工况下突发失控情况的船舶运动过程,并计算了漂移距离,用于指导拖船的紧急部署。研究结果表明:通过CFD分析,能明确不同工况下的拖船应急部署策略。该研究为大型LNG船舶在港口运输中的安全提供科学支持,为港口管理部门提供有效的应急决策依据,以确保港口和航运行业的安全运营。In order to study the safe deployment of tugboats under the uncontrolled situation of large LNG(Liquefied Natural Gas)ships in the dock-constrained waters,and to ensure the safety of port terminal operations,the study adopts the CFD(Computational Fluid Dynamics)analysis method,based on the wind flow interference model,and calculates the hydrodynamic parameters and determines the emergency tugboat deployment strategy by simulating the drift process of the large LNG ship under different working conditions.Taking Wenzhou Xiaomendao as a case study object,the study focuses on analyzing the ship motion process of Qmax LNG ship under the working condition of sudden loss of control,and calculates the drift distance,which is used to guide the emergency deployment of tugboats.The results of the study show that the emergency deployment strategy of tugboat under different working conditions can be clarified by CFD analysis.This study provides scientific support for the safety of large LNG vessels in port transportation and provides an effective basis for emergency decision-making for port management to ensure the safe operation of ports and shipping industries.
