Since the development of the first oil fields on the Norwegian Continental Shelf, the petroleum industry in Norway has been making continuous progress in oil production engineering. With greater environmental awareness and increasing taxation of NOx and CO2 emissions, the economic pressure has been rising in recent decades. The energy demand for o shore oil and gas production is high. With a view to improving power generation on o shore oil and gas installations, four models of di erent 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 o shore installations are discussed and sizing was identified as the major criterion. The power demand of an oil platform and its change during di erent states in field life were analyzed. To complete the simulations, the models were set to o -design conditions and the part-load behavior was investigated. The plant layouts were laid out and visualized with 3D CAD models.
