护舷靠垫影响下的动力定位浮托安装进船工况研究

摘要

动力定位是一种依靠自带动力系统提供定位能力的系统,相对锚泊定位系统更适用于深水作业,动力定位系统正在得到更多的关注和研究.动力定位浮托安装进船过程中,护舷靠垫对安装船的影响很明显.考虑护舷靠垫对船舶的影响,本文对动力定位浮托安装进船过程进行数值模拟,得到了不同角度下的船舶运动轨迹、护舷靠垫力等数据,同时,将结果与动力定位浮托安装模型试验结果进行对比.研究方法和结果可作为动力定位浮托安装系统设计和作业的参考.%DP (dynamic positioning) system relies on its own dynamic system to realize the function of positioning, which is more suitable in situation of deep water working, DP system is attracting more attention and study now. During docking operation of float-over installation based on DP system, influence of fenders on installation vessel is significant. Considering influence of fenders on the vessel, a simulation of docking operation progress is conducted, the moving trails and fender force time series are obtained, a model test is conducted and the result is compared with the simulation result. The study method and result of this paper can serve as a reference in designing and working of float-over installation based on DP system.
