... and an articulated platform, the latter two at 150 m water depth. The data used in the analysis presented here were all recorded during severe storms. The spectral densities presented are obtained by the FFT-procedure applying a Hanning data window. The raw-spectral estimates are further smoothed using a Daniell...

... be decisive for the integrity of the structure, as there is no redundance. Similar considerations apply to joints of articulated platforms. These must have an unambigous reliability throughout the life time of the structure. Simple rugged solutions should be preferred to theoretically sophisticated ones...
