Abstract

Gas turbines have been established as the main power plant for all medium to large aircraft propulsions due to their superior power-to-weight ratio. They also have a significant and growing share in the power-generation sector as a result of the relatively low initial cost, short installation time, high efficiency when operated in combined cycle configurations, and low emissions compared to other fossil fuel power plants. However, their share in the marine propulsion sector is very small because of the more economically viable well-established diesel engine systems. Gas turbines have lower efficiency and poor part load performance. They are however favored when space and weight are at a premium or when high speed is required. It is conceivable that their use may increase, as emission restrictions get tougher. This article aims at giving an overview of gas turbine technology aimed at ship propulsion. Future prospects of carbon neutral zero emissions gas turbine systems are also explored.
