Ship-handling simulator has been widely utilized for various purposes such as training mariners, safety assessment, waterway design, manoeuvrability analysis of new ship at her planning stage and so on. According to the recent diversification of ship and the rapid growth of her size, a database which can cover various ships is requested for manoeuvring simulation with ship-handling simulator.
This paper purposes to configurate ship-handling simulator with a database system on various ships.
As a kind of ship to be applied, twin-screw and twin-rudder ship which has been build recently for the reason of high propulsion efficiency was adapted. Mathematical model of manoeuvring motions for twin-screw and twin-rudder ship was discussed from the viewpoint of hull damping forces at low advanced speed and interaction between hull, propeller and rudder. Using this model, manoeuvring motion of twin-screw and twin-propeller ship was simulated numerically and her principal manoeuvrability was examined. Creating and adding classes related with this model made it possible to configurate of ship-handling simulator considered twin-screw and twin-rudder ship. Also several applications on twin-screw and twin-propeller ship were programmed by C++ language. Finally, a real time simulation of berthing manoeuvre with twin-screw and twin-rudder ship in Pusan Harbor was accomplished by the present simulator.
Through the above study, ship-handling simulator considered many kinds of ship as well as twin-screw and twin-propeller ship could be configurated, and simulator techniques for developing full mission simulator were accumulated.
