Abstract: A new method is suggested to obtain approximate explicit expressions for the dynamic stiffness of rigid foundations on the surface of layered media. The method uses the dynamic stiffness matrices for layered media to compute ...

Abstract: The difference between various approximate methods to compute the wave kinematics and forces acting on a Spar platform up to the instantaneous free water surface is investigated. Three types of procedures are considered; ...

Abstract: A new combined-force method is suggested to approximate the second-order difference frequency forces from diffraction theory (Φ2 theory) with less computational effort. The new method is formulated ...
