One of the serious problems of the Tension Leg Platform (TLP) is the springing phenomenon in the mooring system due to super-harmonic resonance of heaving motion in 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 the present 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 column footing type floating body are computed and these results were compared with experimental results, so that the effects of springing responses are made clear in the tether of tension.
