The added-mass and damping coefficients are found by considering 

 the cases i = 1,2,3. The forces and moments computed using these po- 

 tentials may be separated into components in phase with acceleration 

 and velocity. The component in phase with acceleration yields the 

 added-mass coefficients and the component in phase with velocity yields 

 the damping coefficients. Exciting forces and moments are computed 

 when the case i = 6 is considered.
