The need to look at alternative platform concepts for the development of deep water prospects has lead to the Spar platform concept. The large Spar platform design used in the experimental study discussed in this article was a deep draft cylindrical hulled platform which had a central moonpool. It was designed to be secured to the seafloor using a spread mooring system. The Spar platform motions and wave runup on the Spar were measured and are characterized herein using cumulative probability plots and statistical moments. The plots show the nature and degree of non-Gaussianity. These plots together with the statistical moments provide in­sight into the degree of nonlinearity of the motions and wave platform interactions observed.
