“…With FSRU concept, Sohn et al in their study says that FSRU has an advantage such as the risk to the public is negligible [10]. It is also worth noting that an accident in one onshore plant might produce considerable impact on the neighbouring areas and their population [11]. There are some researchers who compare the areas impacted by undesired events in onshore and offshore terminals in addition to possible consequences of LNG leakages [12], [13].…”

“…The process of FSA started from defining the problem, followed by the identification of hazards, using the preliminary hazard analysis technique (PHA). Later, a risk analysis was conducted by investigating the frequency of occurrence and possible consequences of the identified potential hazardous scenarios; finally, effective and practical risk control options were proposed [11]. But in this paper, the addition safety perspective will only discuss about consequence analysis.…”

In the purposes of reducing emission and as response to the global oil crisis, the Government of Indonesia is currently planning to convert some power plants and ships in Indonesia that is currently using fuel oil to be converted to natural gas (LNG). To fulfil the target, the infrastructure for LNG plant must be prepared such as an establishment of receiving terminal. One of the LNG receiving terminal that will be built in Indonesia is Makassar. The LNG receiving terminal in Makassar will be used as a hub to distribute gas to some power plants in the central part of Indonesia. Hence, this study proposes two stages of designing LNG receiving terminal. The first stage is to select the best alternatives of receiving terminal to be applied in Makassar. There are three alternatives namely: Floating Storage Unit (FSU) and Onshore Regasification; Floating Storage and Regasification Unit (FSRU); and Onshore LNG terminal. The second stage is to conduct the consequence analysis of the selected LNG receiving terminal by means of fire modelling. The selection of LNG receiving terminal in Makassar will be done using a combination of Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) and Analytical Hierarchy Process (AHP). Since AHP has a good hierarchy structure, this method will be used as a weighting of criteria and sub-criteria. The weighting result of criteria and subcriteria from AHP process will be used for the ranking process using PROMETHEE, in this method the weighting will be multiplied with the alternatives preferences. A combination of both methods concluded that FSRU (Floating Storage and Regasification Unit) has the first rank, it means that FSRU will be applied as a LNG receiving terminal. After the selection process, the consequence analysis as well as fire modelling are conducted to assure that FSRU is safe. From the modelling, it can be concluded that only jetty and FSRU itself that will be affected by the fire event both jet fire and explosion.

“…In simple terms, an FSRU is a custom-built vessel that is similar to an LNG carrier. It is mainly a membrane-type vessel that incorporates an onboard regasification system for the vaporization of LNG and delivery of high-pressure natural gas (Figure 7; Martins et al, 2016). LNG is pumped from a cargo tank to the regasification system, where it is vaporized by an external heating source after being pres-surized.…”

The importance of eco-friendly energy sources such as natural gas is increasing globally. This study comprehensively evaluated the economic feasibility of three alternative regasi cation systems for new entrants in the oating storage regasi cation unit (FSRU) business. Life cycle cost analysis with risk expenditure was selected to compare the regasi cation unit `options. Further, the regasi cation characteristics were categorized by heating methods. Failure and accident risk expenditure concepts were also used to optimize the choice of regasi cation unit. This study revealed that the regasi cation unit with seawater-based direct heating exhibited the highest production availability with simple schematics. On the other hand, the regasi cation unit with propane-based indirect heating presented the largest accident risk expenditure because of the usage of propane as an intermediate heating medium. Overall, the regasi cation unit using glycol/water-based indirect heating provided the optimum choice for application to an FSRU, with reasonable capital, operational, and risk expenditures.

“…Fu et al (2016) proposed a quantitative risk assessment model for the potential leakage risk of liquefied natural gas (LNG)-fueled vessels; their methods use event tree analysis and computational fluid dynamics simulation. Martins et al (2016) presented a complete quantitative risk analysis for unexpected events that can happen during LNG processing. Fuentes- Bargues et al (2016) used hazard and operability (HAZOP) analysis and risk evaluation to analyze the risk in industrial plants.…”

Chemical and petrochemical accidents, such as fires and explosions, do not happen frequently but have considerable consequences. These accidents compromise not only human safety but also cause significant economic losses and environmental contamination. The increasing complexity of chemical infrastructures increases the requirements of risk prevention. Thus, risk analysis for petrochemical systems is essential in helping analysts find the weakest process in the entire system and be used to strengthen the process and improve safety. Risk analysis has been previously studied; however, traditional methods have limitations. This study proposes a methodology that is based on Bayesian networks by giving a model for system risk analysis. The event is classified into three categories; cause, incident, and accident, according to criticality and thus, the model is analyzed as a three-layered structure. The application of the methodology is demonstrated by analyzing a vacuum distillation and an atmospheric unit. An exact reasoning method is used to infer the causality and probability within the events. After inferring the relationship between causes and accidents, mutual information and variance of beliefs are calculated to find the most sensitive event in an accident.
