ABSTRACT The design of a marine propulsion system for naval application is challenging, since the high-performance requirements to accomplish a certain mission, usually do not agree with an efficient operation. For this reason, the development of alternative propulsion systems, such as the combination of different prime movers emerged. One of the most efficient arrangement is the CODAG configuration, which combines the use of diesel engines and gas turbines. In this way, the operating profile of a particular vessel can be optimised for high performance and low consumption. This project involves the development of a CODAG propulsion system model in order to optimise the operating profile of a specific vessel. The required power for a particular scenario has been obtained using a Matlab code. It integrates the performance of two high speed diesel engines and an aero-derivative gas turbine based on the GE-LM2500.
