The preliminary experimental results on the scale model of a SPAR offshore platform are presented and analysed. The structure, a classic SPAR, has been designed as a hypothetical model. The study targets to fill a vacuum in the design of such important structures by conducting physical modelling. Changing the wave height, wave period, and ballast conditions, a series of laboratory tests was achieved at 20 mx 10 mx 1.2 m wave basin of the Coastal Engineering Laboratory, UTP, under regular waves while the SPAR is moored by 16 mooring lines connected to the basin floor. The dynamic response of the SPAR was monitored by photographic methods and the heave, surge and pitch of the structure were plotted vs. time. The analysis of the maximum responses showed the significance of the wave period and ballast condition. The scale modelling data show a satisfactory similarity with the prototype
