摘　　要：以一艘800 t海上作业起重船为对象,分析了起升作业、起吊方向对船体运动响应的影响,校核了船体锚泊系统的性能。采用数值分析的方法,建立了吊重系统、锚泊系统的数学模型及仿真分析模型,借助水动力分析软件Ansys/AQWA,对耦合了吊重系统的船体运动进行时域分析。结果表明,起升作业对船体运动响应有抑制作用;不同方向起吊时,船体运动响应存在一定规律。分析结果有助于预测海上作业船舶的运动,确保海上施工的安全性。This paper analyzes the influences that the hoisting operation and direction have on the motion response of the 800 t offshore crane ship and verifies the performance of its mooring system.By using numerical analysis,it estabhshes the mathematical models and simulation analysis models of the hoisting system and the mooring system,and conducts timedomain analysis on the motion of the ship coupled with the hoisting system by using the hydrodynamic force analysis software Ansys/AQWA.The result shows that,the hoisting operation has the inhibitory effect on the motion response of the ship;for hoisting in different directions,the motion response of the ship follows some rules.The analysis result helps predict the motion of the offshore ship and ensure the safety of offshore operation.
