Multiphysics Modeling and Simulation of Integrated Electric Propulsion System for Ship Dynamic Positioning

The paper presents a multiphysics modelling approach to design an integrated electric propulsion system for ship dynamic positioning purposes. The simulation platform integrates the model of the shipboard power plant, the hydrodynamic and environmental forces and the dynamic positioning controller. The shipboard power systems have been modelled considering the electro-mechanical behaviour of the power-frequency dynamic so that the platform can run in real-time and be linked with the controller hardware. The simulation platform has been tested through a detailed simulation campaign by using as a study case a Platform Supply Vessel where its behaviour is harsh condition has been validated.
