| 摘 要： | 针对海洋钻修机井架及底座的安全评估方法的局限性,采用安全检查表法(SCL)、故障类型及影响分析法(FMEA),以及事故树分析法(FTA)从设备隐患的角度出发对井架进行全面的安全评价,结果表明:SCL可有效识别井架及底座存在的隐患,隐患发生在二层台及井架主体部位居多,安装不合理为最主要的隐患形式;FMEA方法可识别出井架及底座常见故障类型、原因,以及影响;采用FTA方法分析梳理出井架及底座常见事故产生的原因。

| Abstract: | In view of the limitations of safety assessment methods for the derrick and base of the offshore drilling and work-over rig,the safety checklist method(SCL),the failure mode and effects analysis(FMEA)and the fault tree analysis method(FTA)were used for safety evaluation of the derrick from the perspective of equipment hidden dangers.The results showed that SCL can effectively identify the hidden dangers of the derrick and base;most of the hidden dangers occur in the second deck and the main body of the derrick;unreasonable installation is the main hidden danger form.FMEA can identify the common fault types,causes and influences of the derrick and base.FTA is used to analyze and sort out the causes of common accidents on derricks and bases. |
