摘　　要：为降低双吊联动吊装超长重大件货的作业风险,根据吊装作业时船舶稳性变化,将整个吊装方案分为货物转动路径规划和船舶稳性调节两个阶段进行设计。采用调拨左右舷压载水的方法调节船舶稳性,通过确定货物的无碰撞转动路径和各步骤所需调拨压载水量设计最终的吊装方案。以实船数据验证了该吊装方案设计方法的可行性。To reduce the risk of dual-crane tandem lifting operation for over-long and heavy cargo,according to the change of ship stability during the lifting operation process,the whole lifting plan design is divided into two stages,the cargo rotation path planning stage and the ship stability regulation stage.The ship stability is adjusted by transferring the ballast water between portside and starboard.The final lifting plan is designed by determining the non-collision rotation path of the cargo and the amount of transferred ballast water at each step.The feasibility of the lifting plan design method is verified by real ship data.
