The paper presents the results of statistical analyses of combined first-order and second-order, sum-frequency response in heave, pitch, and roll of a TLP structure subjected to random, long-crested seas. The results are based on available numerically calculated data for the linear and quadratic transfer functions from the waves to the hydrodynamic loads on the TLP. It has also been assumed that the equations of motion in heavy, pitch, and roll can be reasonably well approximated by a set of uncoupled, linear, and time-invariant equations.
