Research on risk assessment of offshore supply vessels carrying dangerous cargoes

Abstract

In view of the lack of effective quantitative risk of dangerous cargoes carried by offshore supply vessels under the influence of multi-level, multi-variable and non-quantitative factors, the paper adopts the multi-level fuzzy comprehensive assessment method to screen the key risk sources of dangerous cargoes carried by offshore supply vessels, and has respectively constructed the risk possibility and hazard consequence assessment index systems and carried out the risk classification calculation. Through the calculation of the risk of carrying dangerous cargoes on an offshore supply vessel in Bohai Sea, the results show that the risk possibility of the supply vessel is medium to low level, the hazard consequence is medium to high level, and the comprehensive risk level is medium. Therefore, the minimum reasonable and feasible ALARP principle should be followed to reduce the risk. The assessment method can judge the risk level of dangerous cargoes carried by offshore supply vessels and provide technical support for emergency response of offshore supply vessels.
