Offshore mobile drilling platforms are often difficult to carry outsystematic and comprehensive quantitative evaluation because of manyfactors such as the diversified functions of supporting equipment，various structural forms， and many operating parameters。 On the basis ofanalyzing the functional hierarchy of key equipment， combining theanalytic hierarchy process (AHP) and entropy weight method， this paperproposes a comprehensive quantitative evaluation model suitable for thecomprehensive operational capability of offshore mobile drillingplatform。 Taking the mobile drilling platform in service in the SouthChina Sea as the research object， the evaluation criteria layer indexmainly includes four aspects: platform rated capacity， actual operationperformance， equipment failure rate and economy。 Using 0。1-0。9quantity scale， the hierarchical evaluation operator is constructed。Combined with the characteristics of index entropy weight， thecomprehensive quantitative evaluation model and the correspondingsolution method are finally established。 The optimal maps of mobileplatforms in the South China Sea under different operating water depthsand well depths are obtained。 It provides comparative analysis andguidance for the planning and selection of perfect platform for offshoreoil development， summing up and analyzing operational experience。
