Within the past ten or fifteen years the chemical and petroleum (oil and gas) industries have undergone considerable changes. Process conditions such as pressure and temperature have become more severe. The concentration of stored energy has increased. Plants have grown in size and are often single-stream. The response of the process is often faster. The plant contains very large items of equipment. The scale of possible fire, explosion or toxic release has grown drastically. These factors have greatly increased the potential for loss both in human and in economic terms. A distinctive approach to hazards and failure that cause loss of life and property has therefore being emphasized over many years by engineers. This approach is commonly called…show more content…
PSM has been assigned to work on the fire protection measure by applying qualitative and quantitative techniques. One of quantitative approach that is applied for fire protection is the fire grading technique. It is one of the prior steps before performing fire and gas detection mapping (FGDM). FGDM is a software to measure coverage factor of fire and gas system (FGS) for all the PETRONAS offshore and onshore facilities. Thus, this project will covers of the study and methodology used for fire grading techniques. Its purposes and applications will be further explained through the methodology of FGDM. Besides, emphasis will be put on the relationships between fire protection strategy with both fire grading and FGDM techniques. Finally, the outcome of this project will give a clearer and precise answer about fire protection strategy, fire grading and FGDM as well as their…show more content…
(b) To understand the methodology of fire grading techniques and its implementation in FGDM methodology. (c) To understand the methodology of Fire and Gas Detection Mapping and its implementation to measure coverage factor of FGS. 1.2 SCOPE OF STUDY The scopes of study for this project are as follows but not limited to: (a) Perform event tree model to know various type of fire and its integration with the fire grading. (b) Perform fire grading technique based on the failure case data provided by PETRONAS Penapisan Melaka Sdn. Bhd. (PPMSB). (c) Perform FGDM to imply application of fire grading technique in FGDM methodology. 1.3 PROBLEM STATEMENTS Fire grading technique is performed to determine the fire frequency for particular equipment that contains fire hazards. Fire frequency that have been calculated will be categorized into three grades, A, B and C. On the other hand, the utilization of the FGDM has significant contribution to the improvement of FGS functions as the mitigation action after the preventive safeguards have failed. The mitigation from the system could highly reduce the risk of any fire incident on any plants or platforms. However, there are no documents or any technical standards have ever mentioned about the relationships between these two techniques. Therefore, this project will describe and emphasize on the relationship
