Abstract

Floating Storage Regasification Unit (FSRU) is a variety of facilities that support Liquefied Natural Gas (LNG) supply chain activity. There are several potential fire hazards which could be harming human and cause death by the FSRU. This paper will discuss a fire risk assessment on the FSRU loading arms and gas export metering system. To begin, fire risk assessment is carrying out in several stages. The first step is to identify hazards using Hazard and Operability. Then, frequency analysis out of hazards events are complying by the Fault Tree Analysis and the Event Tree Analysis, these methods are to determine the type of potential hazards and to estimate frequencies of events. Henceforth, consequences analysis will be performing by fire modeling software. Finally, the result of the fire risk assessment can be carried out using risk mapping using standard f-N curve UK Offshore, if the risk mapping illustrates unacceptable condition, it is necessary to carry out a mitigation action using the Layers of Protection Analysis. Fire risk assessment indicates that the potential fire hazards which occur are jet fire, flash fire, and gas dispersion. Each hazard has leakage scenarios which are, small-bore (10-50 mm), medium bore (50-150 mm), and full bore (>150 mm). Thereupon, the result of consequence analysis indicates a various form of fire and expose areas which have an impact on marine crews. Based on the risk mapping, the results show that the fire risk assessment which has been carried out is in acceptable conditions and as low as reasonably practicable.
