Abstract

Based on the time domain simulation of the dynamic response of the wreck salvage system in the off-bottom stage, this paper proposes a semi-quantitative safety assessment method for this process, aiming to summarize all motion modes of the salvaging mother ship and provide overall safety assessment scores of the wreck salvage system under different sea conditions. Based on the “Changjiang Kou 2” project, the sensitivity analysis of the system dynamic response under different wave direction angles is conducted. It is concluded that the two wave direction intervals (150°, 210°) and (330°, 30°) are relatively ideal salvage operation windows.

Key words： wreck salvage; time-domain simulation; risk assessment method
