The author calculates velocity potentials involved in the diffraction and radiation problems due to a submerged sphere in water of finite depth. Using the multiple expansion method, the added mass and radiation damping coefficient are determined. Special attention is given to two motions: the surge (horizontal oscillations), and the heave (vertical oscillations). This paper also includes the evaluation of wave forces due to combined effects of radiation and diffraction. This is a standard problem which is solved by usual methods. No physical significance of the solutions is discussed.
