Compressor Station Risk Reliability & Failure Mode Analysis
Most accidents and failures in compressor stations are not caused by a single incident of equipment malfunction or operator failure but are generally a result of a chain of events and errors that interact and/or accumulate to lead to a catastrophic failure. These failure events are extremely difficult to predict using the common single-degree-of-freedom analysis as they are caused by multiple factors and events that are systematically related to each other. This paper describes the development of methods and processes, similar to those commonly employed by the nuclear power and aerospace industries, to compute the risk, reliability, and failure modes within petrochemical related systems. The use of this type of analysis by design engineers, station operators, and risk assessment personnel is discussed. Analysis of actual pipeline compressor and pump stations has been performed and the results are presented.
