Interaction of oblique waves with an infinite cylinder

A Green's function procedure is applied to compute the oblique wave interaction with a cylinder of arbitrary section on the free surface in water of infinite depth. Also, the hydrodynamic coefficients associated with the motion of the cylinder oscillating in its three degrees of freedom, periodic along its axis, are treated. A computer program based on the present procedure is found to be accurate and efficient. The results are applicable to the analysis of floating breakwaters, floating bridges, ship hulls and other elongated structures on a free surface.
