... are presented to demonstrate the limitations of the present computation method. The time series of the surge, heave, and pitch motions in an irregular sea state are compared with the computed time his- tories in Figure 3. The corresponding spectral densities of the measured and computed motions are shown...

.... The second pan of the paper deals with correlation between first and second order surge motions and how extreme' tendon response is influenced by this correlation. Time domain sImulations indicate that the two response types are correlated. It is also concluded that by taking correlation into account...
