The spectral integration points are automatically defined, but will be refined near (1) natural frequencies of the structure system, (2) peak frequency of the spectrum.  Based on these treatments, may I suggest to define the peak frequency at 7.1975 rad/s and the starting/finishing frequencies to be 0.5/1.0 rad/s?  Please also check the water depth in your project, which should be the same as that in the reference paper.  When you did the Hydrodynamic Diffraction analysis, did you set all the structures to be in a hydrodynamic interaction group?
