In the present work, the interaction of an assembly of circular cylinders with regular waves and slow current is considered. The interaction among cylinders is represented by additional waves emitting from adjacent cylinders towards the cylinders under consideration. By means of eigenfunction expansion, drift forces, as well as yaw moment, are evaluated by the far field method and the wave drift damping is deduced from these results semi-analytically. The contribution from the second order steady potential which is quadratic in wave amplitude is also considered. Calculated examples are presented in various wave direction. Those results are also compared with experimental measurements to verify the present theory.
