Research on application of analytic hierarchy process in semi-submersible platform lifting accident factor analysis

Semi-submersible platform lifting accident happened frequently and caused serious consequences for its special working properties and environment. In this paper, analytic hierarchy process was applied to analyze the lifting accident factors qualitatively and quantitatively, an analysis model combining operators, equipments and facilities, environment and safety management was built, and the influence of the factors on working security was evaluated scientifically to reduce lifting accidents.
