Response of Tension-Leg Platforms to Vertical Seismic Excitations
The purposes of the report are (1) to set up an analysis model for the determination of Tension-Leg Platform (TLP) response when subjected to vertical earthquake excitation, (2) to find the hydrodynamic added mass and damping coefficients of a moving cylinder resting on the sea-bed surface and (3) to set up a simple model for determining the slope response of the TLP tendon at its connection with the foundation when the TLP is subjected to horizontal seismic excitation. Presented is a systematic approach, for analyzing the vertical platform motion, tendon force, and foundation uplift when subsea soil is excited by vertical seismic waves. A model, simulating flexural waves propagating in the tendons as produced by horizontal earthquake motions is formulated and analyzed to determine the maximum tendon slope at their base connection point with the foundation.
