• Wave-body interaction
• boundary integral equation
• air-cushion vehicle
• oscillatory water column
• gap resonance

The conventional boundary integral equation for the solutions of linear wave-body interactions is extended to include the radiation solutions because of oscillatory pressures applied on the free surface. Coupled with the constraints that determine the pressure, the extended integral equation is applicable to various problems where a part of the bodies contains the free surface with oscillatory pressures. As illustrative examples, the analyses of wave interactions with an air-cushion vehicle and an oscillating water column device are made. As an additional application, we consider moon pool and gap resonances where the use of oscillatory pressures is an efficient way to introduce artificial damping to suppress excessive free-surface elevation of the potential flow.
