Process Simulation and Plant Layout of a Combined Cycle Gas Turbine for Offshore Oil and Gas Installations

Abstract

Since the development of the first oil fields on the Norwegian Continental Shelf, the petroleum industry in Norway hasbeen making continuous progress in oil production engineering. With greater environmental awareness and increasingtaxation of NOx and CO2 emissions, the economic pressure has been rising in recent decades. The energy demand foroshore oil and gas production is high. With a view to improving power generation on oshore oil and gas installations,four models of dierent power cycles were investigated: a simple cycle gas turbine (currently the default option),a compact combined cycle with enhanced fuel utilization, a steam injection gas turbine cycle as an innovative solution,and a state of the art combined cycle for onshore applications as a reference cycle. Special requirements for oshoreinstallations are discussed and sizing was identified as the major criterion. The power demand of an oil platform and itschange during dierent states in field life were analyzed. To complete the simulations, the models were set to o-designconditions and the part-load behavior was investigated. The plant layouts were laid out and visualized with 3D CADmodels.
