Technical and Economical Comparison of Propusion Alternatives for Modern LNG Carriers

Abstract

In this paper, three LNG carrier alternatives will be compared in terms of technical and economical segments. The three alternatives are dual fuel diesel mechanical propulsion system with 4 stroke medium engines, dual fuel diesel mechanical propulsion system with 2 stroke slow speed engines and combined gas turbine electric propulsion system. Basic technical comparison will be done and the LCC calculation model is the economical comparison model.
