FUNDAMENTAL STUDY ON SPRINGING RESPONSES OF A TAUT-MOORED COLUMN-FOOTING TYPE FLOATING BODY

A serious problem in tension leg platforms (TLP) is the springing phenomenon in the mooring system due to super-harmonic resonance of the heaving motion in the high frequency zone. Second-order sum-frequency vertical wave exciting forces are closely related with the springing phenomenon. When the second-order vertical wave exciting forces are small at the resonance frequency, the springing response will be reduced. In this paper, column footing type floating bodies whose first and second order vertical wave exciting forces are very small at the specific frequency, are applied to the TLP. The properties of the springing responses on the column footing type floating body are computed and these results compared with experimental results, so that the effects of springing responses are clarified in the tether tension.
