During initial ship design, a vessel’s manoeuvrability and propulsion system performance are investigated separately, ignoring the interconnection that actually takes place in real conditions. In this paper, a new simulation tool has been developed by coupling the propulsion system and seakeeping models. The ship’s manoeuvrability is investigated by using a non-linear 3-DOF manoeuvring model in calm water, whilst a mean value approach model is used for the simulation of the vessel’s propulsion system performance. The main outcome of this method is to validate the simulation tool performance by using the available ship’s turning circle sea trials and to simulate her performance and manoeuvrability in shallow water condition. The results include the consolidation of the ship trajectories and the performance of the propulsion system components during turning in various sea depths.
