characteristics, especially the response-dependence on the water depth, of a pontoon type floating
structure in waves. Compared with other existing experimental data, it was found that the hydroelastic
response of a pontoon type floating structure decreased as water depth becomes shallow. This result
could be explained by the decreased wave exciting pressures and the increased added mass effect of
the surrounding water with decreasing water depth, which was confirmed by the wetted vibration
analysis using the finite element method.
