  • Demonstration of the seakeeping calculation results other than polar diagrams and Cartesian plots isimportant during the initial and detail design stages of naval platforms due to the necessity of numericalsimulations (time series data) for the design and validation of the systems on board. These systemsmainly include active roll stabilizer fins, active motion interceptors, rudder roll stabilization, helicoptersecuring & traversing, helicopter visual landing aid, and all sensors & weapons. The simulated timeseries of ship motions and wave elevation may also be used for the naval platform itself to derive theshear force and bending moment distribution of ship sections using ship hydroelasticity theory. Thesetime series simulation as are called as “real time computer experiments”. Similar simulation algorithmsfor ship motions and wave elevation are also used by ship-handling simulators for realistic visualization.The goal of this paper is to create a basis for the simulation-based analysis of ship motions and waveelevation for future design and validation studies for both the naval platform itself and the systems onboard. The results of this study may also be used in ship-handling simulators or helicopter landing onship simulations.
