Paper presented at the The 32nd International Ocean and Polar Engineering Conference, June 5–10, 2022
Paper Number: ISOPE-I-22-255
... ABSTRACT: In this paper, we propose a least square support vector machine (LSSVM) model to predict ocean wave elevations in a random sea state. The frequency and time domain characteristics of historical wave data are both considered in the proposed model. The wave data following a JONSWAP...

... for suppressing non-realistic high wave elevation between two floating barges in close proximity. The Damping Lid coefficient is determined through comparing the wave elevation between CFD and BEM results. It is found that the Damping Lid coefficient is sensitive to the wave height and directions. Furthermore...
