Application of systems engineering to optimize sustainable performance of gas export systems

摘要

This paper presents the use of systems engineering in analysis and optimization of gas export system operation. The Norwegian dry gas export system is selected as the subject for the analysis.rnThere are two important factors that a gas export system shall satisfy. Firstly, the system shall secure that the customers receive the gas that they have ordered. Secondly, the system shall do this in as energy efficient way as possible, i.e. minimize operating costs and environmental emissions.rnFor the operator of gas export systems it is of vital importance that equipment and pipelines in the system are optimally integrated. This will secure flexibility, capability, availability and energy efficiency of the system, and enhance understanding between different system operators.rnThis work demonstrates how systems engineering and information models have been applied as tools for analyzing the integration in gas export systems and existing system operation, and further for developing models that optimize the energy efficiency of system operation. The impacts of gas export system operation on the society are investigated by means of a cost-benefit analysis.
