The theory developed in Part 1 for the hydroelastic behavior of a mat-like floating circular plate advancing slowly in waves is extended in this paper to derive the solution for the second-order wave drift forces. The potential flow theory is employed with low forward-speed assumption and zero-draught approximation. The far-field approach based on the principle of conservation of momentum is applied to obtain the analytical expression for the wave drift forces. Numerical results are presented for a typical plate geometry, which demonstrate the significant effect of the forward speed on the hydroelastic response and wave drift forces. It is also shown that wave drift damping provides an important damping source for the slow-drift motion of a mat-like floating structure.
