SCALING RATIO EFFECTS ON THE PREDICTION OF THE DYNAMIC MOTIONS OF SEMI-SUBMERSIBLE PLATFORMS PROTOTYPE IN THE VIEW OF TESTING FACILITIES LIMITATIONS

As the global energy demand especially for the oil and gas increases, the world has
now turn to the unconventional sources by spreading the offshore exploration and
drilling into the deep water and ultra-deep water. This had brought challenges to the
hydrodynamic research. Currently, physical model testing of deep water floaters,
mooring lines and risers are restricted due to the limitation of the water depth of the
available wave basin in the offshore testing facilities worldwide. There were
numerous studies performed on the methods to overcome the wave basin limitation.
There is however, a lacking in the studies regarding the scale effects on the
responses of the physical model.
