Abstract

In this paper, a method for analyzing the dynamic characteristics of the sunken ship salvage system based on the accurate time history of the seabed resistance force is proposed. The simulation of a typical case preliminarily clarifies the complex interaction mode between the mother ship (a barge), the mooring line, and the lifting line in the lifting stage. It is found that the motion of the mother ship, especially the surge motion, has significantly increased in this stage. In order to better control the motion of the mother ship in the salvage process, the mooring arrangement of the salvage system is also optimized in this paper, and the mooring line arrangement configuration with better motion control effect is obtained.

Key words： wreck salvage; water-soil interaction; time-domain simulation; coupling system
