Risk-based Analysis of Pressurized Vessel on LNG Carriers in Harbor
摘要
The need to understand the associated risks of pressurized vessels and their consequences The need to understand the associated risks of pressurized vessels and their consequences onboard ship is imperative. The handling and storage of Liquefied Natural Gas (LNG) onboard ship is imperative. The handling and storage of Liquefied Natural Gas (LNG) mostly result in catastrophic accident with associated consequences. To quantify these mostly result in catastrophic accident with associated consequences. To quantify these consequences in terms of death and degree of burn depends on the tank structures and consequences in terms of death and degree of burn depends on the tank structures and pressure control mechanism onboard LNG carriers in a harbor. In this research, the result pressure control mechanism onboard LNG carriers in a harbor. In this research, the result of the potential risks and damage consequences of the LNG fire accident in terms of the of the potential risks and damage consequences of the LNG fire accident in terms of the degree of burns and fatality is presented. The probability of death, first and second degree degree of burns and fatality is presented. The probability of death, first and second degree of burn injuries are assessed using consequence modelling technique, while the pool fire of burn injuries are assessed using consequence modelling technique, while the pool fire was modelled using the Boiling Liquid Expanding Vapour Explosion (BLEVE) approach. was modelled using the Boiling Liquid Expanding Vapour Explosion (BLEVE) approach. The result shows that at 30 meters from the flame radius, the probabilities for first-degree The result shows that at 30 meters from the flame radius, the probabilities for first-degree burn, second-degree burn, and death decrease, respectively. A sensitivity analysis revealed burn, second-degree burn, and death decrease, respectively. A sensitivity analysis revealed that at the initial heat flux and closer distance of
