What is it about?
The motion of water in a narrow gap, may lead to large amplitude oscillations and hence wave loads. The phenomenon is normally named gap resonance. It is characterized by vertical walls of water and radiated waves. We present a systematic description of fluid physics so that added mass and damping coefficients can be evaluated with accuracy.

Why is it important?
The problem has drawn significant research attention because of its potential to induce large amplitude motions in the proximity of two floating bodies as well as variations in hydrodynamic pressures that may lead to highly amplified loads. Examples of application to maritime operations include the berthing of an oil tanker alongside a floating production storage and offloading unit, replenishment at sea operations, and channels within large ice floes.
