    This project focuses on voting for 2D fire mapping based on image overlay method. Voting are commonly used in oil and gas industry including in fire mapping activities. In this project, voting are used to calculate the area of coverage for 2D fire mapping. The area of coverage for fire detector is required to meet the standards such as PETRONAS Technical Standard (PTS) for specific area in platform. This is because every area or equipment has different type of risk which determine the grades to the area

    Safety has become the priority for oil and gas industry in order to protect workforce, property and country’s economy. In spite of the oil industry's excellent efforts in the field of fire prevention, it is still necessary to provide fire protection. Oil refinery deals with large amount of hydrocarbons which are highly flammable. Therefore, a reliable and functional fire fighting system is important to ensure safety of the refinery. This research investigates the effect of distance between tanks on fire spread. Hydrocarbon fire of burning tanks will radiate heat to adjacent tank even when fire fighting operation is in progress. In general, some may think that as long as the fire fighting operation is in progress, the fire will be under control. However, in real situation when fire fighting is in progress, the heat release rate of the fuel will decreases but it will continue radiating heat to adjacent tanks which may cause fire spread. Defining the behaviour and heat release rate of hydrocarbon fire when there is fire fighting operation is in progress relating in distance of tanks. This study also adapt fire safety on performance based design where Fire Dynamic Simulator CFD software will be used to study the safe boundary distance of tanks containing hydrocarbon. It has been found from the simulation that when fire fighting operation in progress, fire spread between tanks at distance of 3 meter and 5 meter. However, fire did not spread when distance is 7 meter

    Fire event is a major area of concern especially in the presence of large quantities of hydrocarbons just as in the case of an offshore platform. Thermal radiation is found to be the primary mechanism for causing hazards to individuals, assets and environment as a result of a fire event in open areas. This project aims to assess the fire safety system of an offshore petroleum facility in order to allocate the most beneficial and safest evacuation egress using CFD-FDS software. This should be accomplished by investigating the effect of the produced thermal radiation during the worst case scenario within the offshore petroleum facility platform. Moreover, the researcher will highlight system deficiency and propose recommendation for future facilities layout design (e.g. installation of equipment). The researcher has successfully developed the full-scale model of the offshore platform under investigation. Two mesh sizes were used to measure the evacuation time for the whole facility and found is 248 seconds and 191 seconds for fine and coarse mesh respectively. The produced thermal radiation is vary along the evacuation routes. Preventive measurements should be taken in the locations that detected high incident heat flux which can lead to equipment and human loss. Ground deck is found to be safe except in the location with coordinates of x=15.0, y=15.0, z=6.0 in which a number of 71 occupants will be exposed to 300°C. Upper deck are safe and temperature trends vary in normal range. Thermal resistance wall should be installed in the hazard location for human and property prevention
