The motivation for this work is the stability problem for short-crested Stokes waves. A new point of view is proposed, based on the observation that an understanding of the linear stability of short-crested waves (SCWs) is closely associated with an understanding of the stability of the oblique non-resonant interaction between two waves. The proposed approach is to embed the SCWs in a six-param...

In this paper, we introduce a reduced order model (ROM) for the propagation of nonlinear multi-directional ocean wave-fields. The ROM relies on Galerkin projection Zakharov equations embedded in high-order spectral (HOS) method, which describes evolution waves. dominant flow features wave are computed from proper orthogonal decomposition (POD) and these modes used projection. HOS scheme to comp...

Cylindrical structures are widely employed in the offshore engineering. How to protect the structures in real sea environment is a vital issue for scientists and engineers. In this paper, the interaction of short-crested waves with a concentric surface-piercing two-cylinder system is studied based on linear wave theory using the scaled boundary finite-element method (SBFEM), a novel semi-analyt...

In practice, the ocean waves are short-crested and three-dimensional. The primary objective of present research is to form a better understanding dynamics offshore floating wind turbines in multi-directional waves. modelled using spreading exponent function. wave directionality effect on dynamic performance semisubmersible turbine studied. waves, longitudinal response reduced whereas lateral am...
