This paper explores the probability of occurrence of accidents leading to vapour cloud explosion at one of the topside liquefaction modules of an FLNG. The worst possible scenario with the maximum tolerable probability is identified and the impact of the corresponding vapour cloud explosion is estimated. The strength of the structures supporting the neighbouring modules was examined using finite element analysis to determine if the accident has a potential of escalating to neighbouring modules. Potential Risk of Vapour Cloud Explosion in FLNG Liquefaction ModulesIt is found that the current levels of safety gaps between the liquefaction modules may be insufficient for the structural arrangement in place. It is thought that a new structural design using circular pipes as the structural elements instead of the I-beams may enhance the integrity of the top-side supporting structures against the impact of potential vapour cloud explosion. The effectiveness of the new structure is demonstrated by comparing it to the conventional supporting structure using I-beam members. This also implies that, by using pipe elements, the safety gaps can be reduced, thus making it possible to optimise the topside arrangement more easily.

Stochastic modeling and analysis of vapor cloud explosions domino effects in chemical plants

“…Once the explosion happens, a part of the chemical energy produced by the combustion reaction will turn into mechanical energy, resulting in a blast wave. Blast waves produce a pressure increase that builds up in a first moment due to the combustion, but that subsequently diminishes thanks to the expansion of gasses [24]. This increase of pressure is called overpressure, and it characterizes the blast wave of any explosion.…”

Quantitative Risk Analysis of Oil and Gas Fires and Explosions for FPSO Systems in China

“…Different from the traditional qualitative risk analysis approach, QRA approaches could integrate the probabilistic modeling of accident frequencies and CFD-based consequence modeling of accident scenarios, which can provide an accurate and efficient probabilistic analysis result for the safety design and decision [8,9]. Until now, a large number of fire and explosion quantitative risk analyses have been conducted for all kinds of offshore platforms [9][10][11][12][13][14][15][16][17]. Therein, J. Li et al [10] conducted a gas dispersion and explosion risk analysis for FLNG platforms with and without blast walls and determined the optimal blast wall layout with lowest the explosion overpressure exceedance frequencies.…”

“…A. Rajendram et al [13] applied a CFD-based Fire Dynamic Simulator for the fire risk modeling of offshore platforms and compared and analyzed the accuracy of the CFD fire simulation results. S. Park et al [14] conducted a risk analysis of vapor cloud explosions for FLNG topside liquefaction modules and assessed the effect on adjacent modules under the corresponding explosion based on the finite element approach. Nowadays, most literature considers and assesses the one risk of fire or explosion accidents.…”

Safety evaluation on LNG bunkering: To enhance practical establishment of safety zone

“…Such an uncontrollable release may expose the ship and crews to various risks, such as asphyxiation, cryogenic burns, structural embrittlement and fire and explosion (ISO, 2015a). A number of research warns the potential accidents associated with LNG release (Choi et al, 2018;Dan et al, 2014;Dasgotra et al, 2018;Jeong et al, 2017b;Luo et al, 2018;Park et al, 2017;Park et al, 2018;Vílchez et al, 2013). Tan et al (2014) interestingly carried out a qualitative risk assessment pertinent to LNG release in Beijing city during the Olympic Games, presenting the significant impact of accidents on populated areas.…”
