Pressure surge is a severe problem that causes catastrophic damage to pipelines. Several sequential actions are required to mitigate the pressure surge and protect the pipeline from damage. The present paper investigates the condition at which pressure surge is likely to occur and proposes the methods by which it can be avoided. A hydraulic steady-state simulation and surge analysis is carried out using Pipeline Studio® Liquid version 3.6.0 (PLS) that calculates time-invariant pressure, temperature and flow profile throughout a pipeline network for specified boundary conditions and network element set points. Using the results obtained by steady state simulation as the starting point, the simulation is further carried out for transient conditions. Various pressure trends obtained by exposing the pipeline to various surge occurrence scenarios have been collected and compared with the Maximum Allowable Operating Pressure (MAOP) in pipelines. Result successfully finds out the conditions that causes the formation of pressure surge. Further actions have been recommended that mitigates the formation of pressure surge.
