摘要

Hydrocarbons can be exploded by ignition with the mixture of an oxidizer when the temperature is raised to the point where the molecules of hydrocarbons react spontaneously with an oxidizer and subsequently combustion takes place. The hydrocarbon explosion causes a blast or a rapid increase in pressure. This kind of accidents causes serious casualties, property losses and marine pollution. Therefore, it is need to have considerable study for assessments of explosion. This study introduces and describes a procedure for the quantitative assessment and management of gas explosion risks in offshore installations. A framework for the quantitative risk assessment of explosions requires the definition of both the frequency and consequences of such events. In order to investigate the explosion phenomenon in a quantitative manner, it is essential to use simulation-based methods, such as CFD explosion simulations and nonlinear finite element analysis. The aim of the present study is to develop modelling techniques for CFD explosion simulations and nonlinear structural consequence analysis. Several computations of the aforementioned procedures' application to offshore installations are performed. These procedures can be efficiently applied to offshore development projects, and the application includes the assessment of design explosion loads as well as the quantification of risk control options (RCO) such as platform layout, location and number of gas detectors, isolation of ignition sources etc.
