Based on Matlab/Simulink, a simulation tool has been developed to investigate and predict the dynamic behaviour of ships and their systems. This enables rapid prototyping of control and hardware scenarios, together with optimisation of physical systems and operational parameters. The generic ship simulation model is broken down into discrete blocks, each representing a different part of the propulsion system. This modular approach allows rapid changes to be made to the specification of the vessel, simply by replacing one block with another from a library of components. Comparison between different engines and engine types, propulsors, hull forms, propulsion system configurations and operating profiles can be made. The effects investigated can include, though are not limited to, acceleration and braking performance, speed/power characteristics and fuel consumption. The simulation tool can also be used to determine the mechanical and electrical loads on key propulsion system components, enabling the correct rating of parts for their designed duty. Two case-study examples will be presented to illustrate the application of the simulation tool.
