... ABSTRACT The hydrodynamic characteristics of a moonpool under gap resonance conditions were investigated. The gap resonance was excited by the given harmonic vertical oscillations of the moonpool in calm water. The numerical model, namely an in-house Constrained Interpolation Profile (CIP...

... excitation, the transient effect will arouse a larger peak value at the natural frequency, which requires a longer physical dissipation time to eliminate. Under random excitation, it will not only lead to the increase of energy at natural frequency, but also affect the energy distribution at each order...
