Wave loadings on a vertical cylinder due to heave motion
International Journal of Mathematics and Mathematical Sciences, 1995 Wave forces and moments due to scattering and radiation for a vertical circular cylinder heaving in water of finite depth are derived analytically. These are derived from the total velocity potential which can be decomposed as two velocity potentials ...

On the complete radiation-diffraction problem and wave-drift damping of marine bodies in the yaw mode of motion [PDF]
Journal of Fluid Mechanics, 1998 The coupled radiation-diffraction problem due to a floating body with slow (time-dependent) rotation about the vertical axis in incoming waves is studied by means of potential theory. The water depth may be finite. First, the radiation problem is described.
