Recently, efficient numerical analysis code has been developed for pontoon-type VLFS with the capability to analyze hydroelastic responses in regular waves of relatively short wave length.
Using these response amplitude operator, time domain analysis can be performed for the responses in irregular waves by linear superposition principle.
By the same manner, the response to the impact due to dropping object or landing of aircraft on the VLFS can be estimated.
This paper deals with the numerical calculations of time series responses in irregular waves and the response to the impact or moving load. The numerical results were compared with model experiments showing good agreement.
