<b>ABSTRACT:</b><br> <br /> Earthquake in active seismic zone has to be considered in analysis of Tension Leg Platform (TLP) structure. Some methods for analysis of structure. response has established but the methods has not been applied for TLP structure. Water surrounding of TLP and wave force factor causes it. For these reason it is needed to simpl fly of response analysis to obtain the TLP structure response. Mod flying is done to mathematical model, which shows the TLP response especially some effects of TLP parameter due to wave and earthquake acceleration.</p> <br /> Firstly, analysis of some aspects of dimensionai and shape of TLP structure and also the TLP motion due to wave and earthquake acceleration. The first aspect includes lumped mass, added mass, hydrostatic stiffness of hull, consistent mass, elastic stiffness, and damping of tether and mass, damping, and stiffness of foundation. The second includes regular wave force and earthquake acceleration. Earthquake acceleration, which is used in analysis, is vertical earthquake acceleration and horizontal of Electro, Jayapura, and Denpasar.</p> Mathematical model of TLP equations is obtained from aspects above. These matrixes from model are used as input of Newmark integration program to determine displacement time history and acceleration of structure TLP. <br /> Finally, the results, which are obtained above, are shawn vertical earthquake acceleration and horizontal effects, current and pretension effects, and soil property effects to TLP structure. And also show earthquake acceleration which is used to analysis TLP in Indonesia.
