This study aims to provide the approach for inherent safety design of onshore LNG plants to be applied at the very early stages (concept definition phase) of the project development. Onshore LNG plant development project starts from the %26quot;Concept Definition%26quot; phase, where financial feasibility is estimated and major conditions, such as site location and plant foot print, are set. %26lt;br%26gt;The inherent safety design basic criteria and design measures should be identified and selected when setting the basic conditions during the Concept Definition phase of the project development, such as the site location (relative location from populated areas), site condition (prevailing wind direction) and plant production capacity (number of process train, number of product tanks). The safety measures, which are usually not fully developed at the project early stages in the current design execution practices, are the emergency systems, which mitigate an accident escalation, the modularized plant and layout, and the tank selection. %26lt;br%26gt;The inherent safety design measures discusses in this paper were identified based on the categories of plot plan, emergency system, and module plant application. %26lt;br%26gt;The proposed approach will contribute to improve inherent safety design of onshore LNG plants and it will also yield schedule and cost benefits.
