Abstract: A complete second-order solution is given for the hydrodynamic forces on a pair of bottom-mounted, surface-piercing, vertical circular cylinders in bichromatic seas. The constant structural cross-section allows the vertical dependency of the linearized potentials to be expressed in terms of eigenfunction expansions and so the first-order problem may be solved utilizing a two-dimensional Green's function approach. An efficient numerical technique is presented to treat the free-surface integral term in the second-order force formulation. Numerical results are presented which illustrate the importance of second-order hydrodynamic interactions on the forces experienced by the cylinders.
