Failure Mode Analysis Based on MFM-HAZOP Model of Gathering System

Gathering system is not only an important oilfield production facility system for gathering and transporting oil and gas but also is a key section to realize the function of oil and water separation. However, the high complex failure coupling relation among separate production process sections, personnel operation, and equipment leads to which is a complex high potential hazard and failure relational degree within subsystems production system, make it difficult to analyze failure mode. Therefore, it is urgent to demand a higher level effective operational failure analysis model to simplify the complex gathering system to resolve the realistic safety problem. A failure mode analysis of gathering system based on a novel MFM-HAZOP deep knowledge model is proposed. By decomposing goals, functions and components, a graphical MFM model of gathering system is established. Combined with HAZOP analysis technology, this paper sets up MFM-HAZOP model to perfect studying failure mode of gathering system and accurately analyzes reason of failures, which is the base of gathering system safety decision to guarantee the gathering system safely operating.
