This paper discusses the case study of retrofit of Fire & Gas system for a process gas compressor at an offshore oil & gas installation in Mumbai High-India. Fire & Gas detection system is a key component in the overall safety and operation of offshore process gas compressors. Worldwide, efforts are going on to bring F&G detection and mitigation systems under the broad framework of functional safety systems which follows the concept of safety life cycle of the system. Safety life cycle begins with the conceptual design and ends with de-commissioning of the system. Backed by seventeen years of offshore working experience of author, present paper critically analyses the retrofit job in context of safety life cycle as mentioned in functional safety standard of ANSI/ISA S84.1.
