The potential risk of explosion always exists in offshore topside facilities that deal with flammable materials. Thus, explosion risk analysis taking into account possible scenarios should be performed during the design process to reduce probability of such terrible accidents. There are several technical documents for explosion risk analysis. The analysis usually includes performance criteria, risk acceptance range, and corresponding explosion design load taking into account explosion pressure. However, this standard procedure is not sufficient to assess the potential risk of explosion, since it is usually based solely on the severity of overpressure. Therefore, more in-depth analysis is required to understand the potential risk taking explosion wave profiles into account. In the present paper, a stepwise analysis of gas explosion risk elements has been performed. Quantitative and qualitative analyses of explosion risk have been performed based on the framework of typical explosion risk analysis methods. In addition, both the probability distribution of explosion load parameters taking into account overpressure and its impulse and their correlation have been investigated extensively.

“…Another large-scale natural gas storage method that stores natural gas as the hydrate has recently been gaining signicant attention. 9 Takeya et al [10][11][12][13][14] have found that the methane hydrate could be preserved for one week at 248 K and 0.1 MPa because of the ice sheet formed around the methane hydrate particles. So the preservation time is longer than that of LNG at 248 K and 0.1 MPa.…”

“…Offshore platforms are divided into number of modules for operations such as drilling, separation of oil, gas and water, high pressure compression, water injection, and de-aeration. 1 Majority of the modules are very congested and confined due to complex piping structure, compact geometry, and equipment installed in closely spaced configuration. 1,2 Accidents in offshore processing areas may lead to release of hydrocarbon fuel, which may quickly escalate to major hazards such as fire, explosion, and toxic products.…”

Vapor cloud explosion (VCE) accidents have the potential to cause loss of life in offshore platforms. In order to quantify risk, quantitative risk assessment has served as a robust methodology. However, previous research focuses on macroscale assessment of risk which does not take into consideration the local specific details such as piping and equipment congestions. The overpressure developed by VCE is greatly influenced by local specific details. In addition, VCE occurs due to the ignition of vapor cloud that is influenced by parameters such as wind speeds and directions. This study investigates the effect of different wind conditions on VCE and resulting human injury and fatality risk by employing a grid‐based approach in an offshore platform. Flame Acceleration Simulator software is utilized to model dispersion of vapor cloud and resulting VCE. The methodology is an integrated tool that enables a grid‐by‐grid mapping risk, thereby providing a complete and precise picture of risk in all the locations. It was found that risk values were increased to maximum of 91% when wind speed was increased from 0 to 7 m/s. Among four wind directions, West to East wind direction recorded maximum risk values and South to North wind direction recorded minimum risk values.
