The purpose of this study is to analyze the behavior of a TLP by means of an analytical method with multiple lumped-mass system applying to its tendons, when it is subjected to vertical component of seismic excitation. The result of analysis is compared with obsevational data obtained with an experimental model of the TLP placed at the sea 60m in depth. After verification of the analytical method with the experimental model, the behavior of the prototype TLP is simulated and discussed in comparison with analytical results obtained by an analytical method with spring system applying to tendons. The results of this study are as follows. (1) Analytical results coincide well with observational data. (2) Higher-order oscillations of tendon should be taken into account in the design of TLP for deep sea, where weight of tendons is not negligible in comparison with that of a hull.
