The laboratory study of the FWEPS model behaviour in waves

The computation and hydrodynamic development of a small-sized laboratory model of the FWEPS prototype were carried out for the subsequent physical modelling in the KSRI’s seakeeping basin.

The computational scheme allows getting statistical characteristics of vertical and angular motions of a buoy with oscillation system inside. The test facilities includes seakeeping basin, wavemaker for generation of irregular waves, towing carriage with associated equipment, model restraining system in waves.

The objective of the study is to determine modelling parameters of the buoy motions as well as pendulum oscillations with respect to its body. The results of physical modelling irregular-sea behaviour of the FWEPS model at Sea States 4 - 5 numbers demonstrate that devices are basically serviceable in terms of relative vertical motions of the internal pendulum.

Analysis of the wave behaviour of FWEPS models indicate to a significant effect of the mean wave period and to a less pronounced dependence of buoy - pendulum relative motions on the Sea State within its investigated range.
