Numerical Simulation and Analysis of Trans Summer Salvage during Refloating Operation
ZHANG Yong-qiang;Guangzhou Salvage;
The control condition of refloating operation for the large-tonnage sunken vessel salvage was presented and the analysis and numerical simulation method of the refloating operation with the GHS software was proposed. Taking the salvage of the sunken vessel Trans Summer as an example,the bending moment,shear force,floating status of the sunken vessel were simulated for the different load cases caused by the variation of water in the cargo tanks and the stern floating crane lifting force,so as to obtain the optimized refloating scenario. The calculated result was highly agree with the practical engineering data,and the integral refloating of the sunken vessel Trans Summer is finally achieved.
