Abstract:

This research investigates the concept of the Fire and Gas Mapping approach by performing as-built drawings, the steps involved, and the problems encountered while executing Fire and Gas Mapping. The methods used to gather information are the existing process data, questionnaires survey, and site observation. Facility management can be effectively improved by keeping as-built documentation in form of records, structure drawings, piping drawings, specifications, and location of equipment. This study also compares the alternate techniques (Laser scanning, Photogrammetry, Videogrammetry, 3D range camera, and the importance of physical measurement (Along with the Camera)) in the oil & gas industry to generate the 3D model for old installations. The oil & gas industry is dynamic in nature, and it frequently undergoes revamping work to enhance production capacity or to maintain/replace existing equipment. This study will help old installations without having the latest plant documentation in making technically reliable and cost-effective decisions to design FGS, with the developed set of guidelines. The Fire and Gas Mapping study is typically based on client-specific gas detection design philosophy, performance-based approach as specified in ISA-TR.84.00.07-2018 (Technical Report – Guidance on the Evaluation of Fire, Combustible Gas, and Toxic Gas System Effectiveness) and OISD 116 (Fire Protection Facilities for Petroleum Refineries & Oil/Gas Processing Plants) to effectively design FGS. Detector coverage assessment tool is used to achieve the required coverage targets.
