THIRD AND HIGHER ORDER CONTENT OF TLP SPRINGING EXCITATION

This paper describes an investigation quantifying to what extent the springing excitation on a tension leg platform can be fully described by quadratic wave forces, or whether third and/or higher order forces make a significant part of the excitation. The applied method of investigation consists of comparing experimentally measured excitation forces in irregular waves with corresponding forces obtained by a synthesis based on the experimentally determined quadratic transfer functions. The conclusions are that in low sea states (4m significant wave height and less) the springing excitation on the TLP is dominated by quadratic forces. In higher seastates (8m and more) only a small part of the excitation is of quadratic type.
