Gas Turbines and Associated Auxiliary Systems in Oil and Gas Applications

Abstract

This tutorial elaborates on the various gas turbine auxiliary systems; for mechanical drive applications in oil and gas projects, from an EPC contractor perspective. The tutorial briefly introduces the basics of gas turbines including thermodynamics, types, arrangements, components and combustion technologies. However, the focus of this tutorial remains on the gas turbine auxiliaries where the functions and technology selection options are explained; furthermore, the relevance on the gas turbine performance and availability and the technical constraints for implementation are described. This tutorial contributes; in addition to what have been previously published, by being focused on the engineering of interfaces between the gas turbine, its auxiliary systems, and the plant in oil and gas onshore and offshore projects.
