A range of Process Hazard Analysis (PHA) tools are used throughout the Oil & Gas industry in hazard identification and analysis, to understand the effects to the system as a result of the hazards and to eliminate/reduce/mitigate the identified hazards. Prognostics and Health Management (PHM) is a life cycle concept introducing an integrated approach to the health management of a system through the design and operation cycles. Therefore, if projects can be developed within a PHM environment, this may lead to greater integration between the stakeholders, with the potential for a technically superior product developed with cost and efficiency savings. This paper demonstrates that functional analysis software applications can facilitate sensor set design to detect and isolate faults associated with the system’s components and that those are comparable – with some manual adjustment – with the traditional approaches used in sensor set design. The results also show that a functional analysis approach is a viable tool in the PHA process i.e. it can generate FMECA reports and can be used to complement HAZOP studies. Finally using a PHM functional modelling application can benefit the main stakeholders in terms of demonstrating reliability, availability and maintainability of equipment whilst realising cost savings and improved efficiency.
