The study of waves and wave loading on submerged structures has been the subject
of active research since the days of Havelock [4], and in practice, he can be considered
as the pioneer in this area of research. A British electrical engineer turned applied
mathematician, Havelock contributed tremendously in the field of water waves. Havelock’s
pioneering work investigating the vertical motion of a floating hemisphere in
infinite water depth was extended by Hulme [5] to investigate the added mass and
radiation damping. Gray [3] studied the scattering problem of a submerged sphere
by expanding Green’s function and the associated velocity potential in spherical harmonics.
