Fluor's Surge and Operability Analysis confirms the safe operation of the gathering process and pipeline systems. The analysis provides an evaluation of the surge effects emanating from pump trips, valve closures, and other potential upset conditions that could jeopardize operations. Calculated surge pressures can also be used in piping stress calculations to confirm that surge effects do not compromise piping integrity. Fluor uses proven industry tools to complete the analysis. The analysis includes modelling the control system to confirm overall system operability against upset conditions.
