In order to reduce the peak tension in the hoisting steel rope and to salvage the SEWOL by using the double barges under the complicated sea conditions, the hydraulic tension buffer system was designed, and its function in salvage project of double barges was evaluated. The features of coupling motion with three hulls (double barges/SEWOL) were respectively studied by numerical simulation and experimental analysis under different lifting heights and different sea conditions. The multi-body hydrodynamic characteristic parameters were calculated by using boundary element method, and system coupled response simulation model was set up. The hydrodynamic characteristic parameters were calibrated by model test results to significantly increase the accuracy of the overall coupled response simulation model. Based on that model, both static and dynamic time domain simulation were conducted, and simulation results of two conditions (with or without hydraulic tension buffer system) were compared. Results show that numerical simulation analysis results coincide with model test well, which indicate that the numerical model has higher reliability. The hydraulic tension buffer system can improve evenness of static sling tension distribution effectively, and reduce maximum dynamic lifting force, which achieve the design function in SEWOL salvage project.
