Techno-economic and environmental risk analysis for advanced marine propulsion systems

► A method for the techno-economic, environmental and risk analysis of marine propulsion systems is presented. ► A tool has been developed, comprising modules for engine and ship performance, engine life, economic, emissions and risk. ► The tool enables the evaluation of powerplants in terms of net present cost, through a holistic approach. ► Risk assessment is performed through a stochastic approach, for taking into account uncertainty in future scenario parameters. ► Two different engine configurations have been tested and compared in terms of fuel burn, emissions and overall cost.
