摘要：特殊的工作环境与独特的工作对象所带来的安全风险，使钻井平台施工归于严重的危险源之列。在世界范围内，因施工事故造成沉没的钻井平台已达 60余座。在给人们带来巨大经济损失的同时，也给海洋环境造成了难以弥补的伤害。因此，对钻井平台进行危险辨识及作出与其相对应的安全对策十分重要。在本文中，以CJ46 自升式海上钻井平台施工为例，通过对钻井平台整个施工过程进行定量和定性分析后，找出其危险有害因素并建立起某钻井平台施工安全评价体系。运用 SPA（集对分析法）和模糊评价法，得出该钻井平台施工的安全等级，并针对其安全评级系统的薄弱环节，给出相对应的安全对策。该模式简单易行， 对防范海上钻井平台施工安全事故的发生具有一定的实际价值和启发意义。57163

Risk identification and Countermeasures for constructionof a drilling platform
Abstract：Security risks special working environment and unique work of objects brought thedrilling platform construction attributed to a serious source of danger columns.In the world, dueto construction accidents caused by the sinking of the rig has reached more than 60.To bring inhuge economic losses, but also to the marine environment caused irreparable harm.Therefore,the drilling platform to hazard identification and its corresponding security measures is veryimportant.In this paper, in order to CJ46 jack-up offshore drilling platform construction, forexample, by drilling platforms throughout the construction process of quantitative andqualitative analysis to identify the risk factors and harmful to establish a drilling platformconstruction safety evaluation system.Using SPA (Set Pair Analysis) and fuzzy evaluation,obtained the drilling platform construction level of security and safety for its weaknesses ratingsystem, gives the corresponding safety measures.The model is simple, to prevent offshoredrilling platform construction safety accidents has a certain practical value and instructive.
