Models for Evaluating Use of Synthetic Fuel in Ship Power Plants

An approach is described for modeling the fuel systems components serving ship generating plants to refine the accuracy of endurance and annual fuel use calculations. Models were formulated for Operating Point analysis in a tool such as the S3D component of the Rapid Ship Design Environment but the model formulations are presented generically and can be encoded for any other suitable analysis tool. The formulations refer to a specific reference case in which ammonia is considered as a fuel, but the modeling method can be applied to other fuels by changing the fluid parameters or the combustion chemistry.
