Abstract: Oil and gas explosion is one of the main risks of offshore platforms. Structural design based on explosion risks is the development trend of the design technology. The technical regulations and specifications related to risk analysis are reviewed to summarize the procedures for the assessment of the blast risk, and the method and procedures for the assessment of the blast-resistant performance of the structure. The screening analysis, strength level analysis, plasticity level analysis and performance assessment are carried out to complete the risk-based assessment of the structural performance design for the accommodation of a FPSO offshore platform by using the structural finite element analysis software. The structural designs under different blast risk levels are performed based on three performance levels of function, operation, and life safety, designing out a scheme that meets the criteria of each performance level.

Key words: floating production storage and offloading unit(FPSO), accommodation structure, blast risk based design, performance design level, blast resistance

摘要： 油气爆炸是海洋平台主要风险之一,基于爆炸风险的结构设计是设计技术发展趋势。该文梳理风险分析相关的技术法规、规范,总结了爆炸风险评估流程、结构抗爆性能评估方法及流程;以某浮式生产储卸油装置（floating production storage and offloading unit, FPSO）海洋平台生活楼为依托对象,利用结构有限元分析软件,分别开展了筛选分析、强度水平分析和塑性水平分析,完成基于爆炸风险的生活楼结构性能评估;基于功能性、作业、生命安全这3个性能水平,开展不同爆炸风险水平的结构设计,得到满足各性能水平衡准的设计方案。
