Safety Analysis Methodology in Marine Salvage System Design

Abstract

Abstract. In order to assess the risk of marine salvage system, the paper introduced a safety analysis method based on fuzzy-logic theory, which could deal with the uncertainties in scheme design process. The method consisted of three steps: (i) problem setup, (ii) risk assessment, (iii) risk mitigation and decision making. Then two mission phases were identified in typical salvage system, namely, refloating the vessel and towing the vessel. Main hazardous events of each mission phase were researched and a safety analysis model was introduced subsequently. An example was studied to demonstrate the application of the model, and the results showed that salvage method, the operation of pontoons and the safety of towline should be taken into account seriously in salvage system design.
