Abstract
It is possible to anticipate motion of a vessel theoretically or experimentally, experiments are costly, time-consuming, and impractical in the early stages of design. Therefore, at least in the initial stages of ship design, the designer mostly relies on theoretical methods. Cargo vessel transport cargoes from one countryport to another and passes through sea. The wave disturbance on the sea is sometimes of great magnitude which is devastating on the vessel and cargoes. The analysis of the effect of wave on cargo vessel motion were determined in heave and pitch force and moment acting on the vessel with varying wave direction from 0o to 120o. The analysis was estimated using MATLAB. While from 30o to 120o wave directions, the Sw5 fluctuates between 0 m2srad to 0.2777 m2srad (30o), 0.8746 m2srad (60o), 1.1944 m2srad (90o) and 0.9172 m2srad (120o), which later dropped to 0.1632 m2srad (30o), 0.5618 m2srad (60o), 0.7992 m2srad (90o) and 0.6388 m2srad (120o) respectively. From the analysis, the wave response effect on the vessel is more significant at 90o wave direction than at any other wave direction.
