| Summary: | A comparison between short-crested wave and long-crested together with the presence of ocean current that induced dynamic response on Truss Spar wave studied. A short crested wave is defined as a combination of long-crested waves that propagated from different directions. It is more complex and suits the real sea state. In this paper, numerical study on the dynamic responses of the truss spar due to both ocean waves and current was performed. The physical motions in surge, heave and pitch will be analyzed in terms of the max peak, minimum peak and amplitude of the time series generated from the Response Amplitude Operator (RAO). The responses due to the Short-crested waves with current expected to provide a lower responses to the truss spar compared to the long-crested one. |
