Abstract: Tension leg platform (TLP) is a type of offshore platform suitable for petroleum exploration in
deepwater. The dynamic responses of TLP such as the motions and the tether tensions when it is subjected to
wave forces are needed for the design and maintenance of the structure. Limiting these responses leads to better
stability and safe drilling operations. In this paper, the triangular TLP has been considered as a rigid body and
all the six motions as well as tether tensions have been determined. Linear Airy wave theory and Morison
equation have been used for wave force calculations. Newmark Beta method of time domain analysis has been
used. The response amplitude operators for the motions of a typical TLP have been studied. Also, parametric
studies for triangular TLP have been made varying parameters such as water depth, pretension, wave angle and
position of centre of gravity (CG). The results highlight the variation in platform responses caused by changing
these parameters.
Keywords: Tension Leg Platform (TLP), triangular TLP, Dynamic response, parametric study.
