(1) Please see Aqwa theory manual, Section 13.5.3 Motions at Drift and Wave Frequency, the RAO based motion, velocity and acceleration are given by

 

in which the irregular waves are represented by 

 

(2) For actual acceleration calculation, the predictor-corrector algorithm is employed, and the raditation forces is caluclated by the impulse function convolution,

the velocity and position is then calculated by
