摘　　要：浮式生产装置上部模块布置密集,有发生爆炸的风险,为了降低事故发生的危害,该文以某个浮式生产装置上部TEG(三甘醇)脱水模块结构为研究对象,采用有限元软件ABAQUS进行爆炸动力响应分析,考虑从初始状态至结构垮塌的全过程。根据研究对象设计爆炸载荷脉冲峰值及持续时间,并考虑三个不同爆炸源方向的影响。计算结果表明,在设计爆炸载荷作用下,沿船宽方向的爆炸会导致材料失效断裂最终整体垮塌,其余工况下整体模块结构不会发生倒塌。计算结果对TEG脱水模块结构设计具有一定的参考意义。The dense layout of the upper module of the floating production unit(FPU) is prone to the risk of explosion.In order to reduce the harm of accidents,this paper takes the TEG(triethylene glycol) dehydration module structure of a floating production unit as the research object,finite element software ABAQUS was used to analyze the dynamic response of explosion,considering the whole process from initial state to collapse of structure.The peak pulse value and duration of explosion load were designed according to the research object,and the influence of three different explosion source directions was considered.The calculation results showed that,under the designed explosion load,the explosion source along the ship width direction will lead to the material failure and fracture and eventually collapse,but the whole module structure will not collapse under other working conditions.The calculation results have important reference significance for TEG dehydration module structure design.
