TLDR
The finite element method for solving the linear floating body hydrodynamic problem is considered with a hierarchy of boundary damper options for modelling the far field as discussed by the authors, which is validated using two simple examples for which added mass and damping coefficients are computed over a wide range of frequencies.About:

Wave radiation from multiple cylinders of arbitrary cross sections
TL;DR: In this paper, a semi-analytic model based on linear potential theory is developed to solve wave radiation from an array of truncated cylinders with arbitrary cross sections, free to oscillate independently in water of finite depth.

Absorbing boundary condition on elliptic boundary for finite element analysis of water wave diffraction by large elongated bodies
TL;DR: In this paper, two new elliptic dampers are proposed, one for beam-on incidence and the other for general wave incidence, and the performance of all the three dampers is studied using a numerical example of diffraction by an elliptic cylinder.

An Investigation into the Liquid Sloshing Characteristics of Ground Anchored Tanks during Lateral Vibration
TL;DR: In this paper, the authors presented an experimental cum analytical investigation on lateral sloshing behavior under simulated vibrating conditions on a fixed base rectangular container with water, which was designed to suit experimental requirements and the walls were made of Perspex sheets in order to view the slohing phenomena and for image capturing purposes.

The applied dynamics of ocean surface waves
TL;DR: In this article, the authors present selected theoretical topics on ocean wave dynamics, including basic principles and applications in coastal and offshore engineering, all from a deterministic point of view, and the bulk of the material deals with the linearized theory.

Calculation of non-lifting potential flow about arbitrary three-dimensional bodies
John L. Hess,A. M. O. Smith +1 more
TL;DR: The method utilizes a source density distribution on the surface of the body and solves for the distribution necessary to make the normal velocity zero on the boundary and the flow velocities at points both on and off the body surface are calculated.

The wave forces acting on a floating hemisphere undergoing forced periodic oscillations
TL;DR: In this paper, the added mass and damping coefficients associated with the periodic motions of a floating hemisphere are derived for two physically distinct cases of heave and surge, where these nautical terms refer respectively to a vertical or horizontal oscillation of the body.

The motion of floating bodies
TL;DR: In this paper, the authors consider the case of a ship lying dead in the water and assume that the body does not disturb the water much during its forward motion, for example, slenderness or thinness.
