Developing mathematical model for calculating forces affecting to Ship motions

Mathematical model of ship motion is considered as an artificial brain deciding the capability of a bridge simulation system and ensuring the reality of ship maneuvering. Due to the huge development of shipbuilding industry ships have been being equipped with a variety of non-conventional propellers and rudders the existing mathematical models need to be improved accordingly. Moreover, training simulators nowadays require more external and environmental forces to be integrated into the system for more reality. This study aims to review previous studies on mathematical models of ship motions and proposes a development to the synthetic model of forces for systematically and simply simulating ship motion in six degrees of freedom in realtime mode.
