The distribution of the local damping force and moment along a submerged spheroid, oscillating in heave and pitch at zero forward speed, is found in this note. Two different methods of calculation (local energy radiation and the extended Lagally theorem) were used and they were shown to yield equivalent results. The influence of three-dimensional effects is shown to be important at all sections, including the mid-section, and this is not exhibited by ratios of total three-dimensional to two-dimensional damping. The importance of these findings for bending-moment calculations in waves is stressed.
