该文在广泛调研国内外已发生的海洋平台事故基础上,从人因失误、工艺设备、物料危险、管理缺陷和危险环境五个方面系统分析事故致因因素,提出海洋钻井平台事故致因评价框架,提出5个一级评价指标和24个二级评价指标,根据层次分析法,计算确定各指标的标准权重值.最后针对某在役海洋钻井平台,开展实例研究.为实际评价海洋钻井平台事故风险提供一种新方法,具有一定的实际应用价值.%In the paper, accident-causing element consisted of human error, process equipment, oil and gas hazard, management error and environmental hazard, was studied systematically. On the one hand, accident-causing e-valuation framework for offshore drilling platform was proposed based on the wide investigation about the accidents of offshore platform happened at home and abroad; on the other hand, the evaluation indexes, comsisted of five main parts, including human error, process equipment, oil and gas hazard, management error and environmental hazard, and the other 24 secondary evaluation indexes, were presented in the evaluation framework. What's more, the weights of all the evaluation indexes were calculated with the help of analysis hierarchy process and Matlab software. In addition, the evaluation framework and indexes were applied to an offshore drilling platform in service, it was found that the jack-up was in critical state and inclined to safety state. This paper presents a new methodsfor risk evaluation and control of offshore drilling platform in China.
