Many facilities have now implemented and maintained process safety management (PSM) programs for 20 years or more, but these facilities continue to have sometimes serious incidents and injuries suggesting a continuing need to improve their PSM performance. Of course, new requirements are often added to upgrade PSM programs, due to near‐miss learnings, audit findings, and new recommended and generally accepted good engineering practices, for example, but often overall performance improvements have not occurred or have not achieved the desired level of performance. How can significant performance improvements be obtained? Although performance issues at different facilities will certainly vary, this article provides several key approaches for improving overall PSM performance and for helping prevent injuries and incidents. © 2012 American Institute of Chemical Engineers Process Saf Prog, 2012

“…It was originally contributing the process safety for decision-making process for the MET institutions while planning the further needs of LNG industry during the planning of their related curricula (Istanbul2007). Qi et al (2012) have addressed some of the critical challenges in implementing effective safety programs: (a) failure to learn from past incidents and to capture those lessons into process design, procedures, training, maintenance and other programs, (b) insufficient attention to leading indicators and (c) an increase in complexity of process operations and lack of communication. In the presence of these challenges, there was a great need to develop better solutions by utilizing good science-based approaches and best practice studies.…”

Global demand for liquefied natural gas (LNG) is projected to double by 2040, with gas playing a significant role in a less carbonintensive power system, to 700 million tons. The risk assessment and vulnerability analysis of liquefied natural gas regasification plant have predominant importance due to increase in demand. Determination of safety integrity level (SIL) for process industries becomes a contemporary relevant factor. The reliability of various equipment used in process plants is critically important to maintain safety standards; malfunctions of these instruments may result in accidents which will affect property, environment and people. The main aim of the work is the risk assessment of liquefied natural gas to identify and rank failures that could result in the release of liquefied natural gas to the surrounding environment. In this paper, we integrate fuzzy risk matrix and layer of protection analysis (LOPA) to find safety integrity level value of each Independent Protection Layer (IPL) of seven scenarios of the liquefied natural gas storage facility. Seven scenarios were identified using hazard and operability analysis (HAZOP) as a process hazard analysis (PHA) tool, and we compare the safety integrity level value with Field Device Tool (FDT) method and risk graph is used to find the risk reduction factor (RRF). The safety integrity level determination using fuzzy methods gives more accurate result when compared with the risk graph methods and also describes the safety issues and hazard characteristics in liquefied natural gas terminal and consequence analysis if a liquefied natural gas tanker at the terminal releases liquefied natural gas due to natural and external man-made events, like recent issues between Saudi and Iran regarding oil transporting through Arabian Gulf, and accidents due to projectile effects. Process Hazard Analysis Software Tool (PHAST) and ALOHA software enable to analyse consequence having exorbitant complexity all while considering weather conditions, usage of land and population in the locality. In this paper, atmospheric dispersion modelling and evaluation of flammable and toxic effects have been done by Process Hazard Analysis Software Tool 8.11. Relationship between SIL, PFD avg and RRF is analysed. The frequency, severity and risk values are also gathered. Fuzzy risk values and SIL for each IPL from fuzzy LOPA are obtained, and furthermore, risk reduction SIL values, FDT method to calculate SIL and release scenario are investigated. Comparing the SIL values from fuzzy LOPA approach and FDT method, the consequence analysis of LNG spills from carrier ship due to natural cause using PHAST 8.11 and LNG leak from carrier ship due to man-made cause using ALOHA is also investigated.
