Numerical and Experimental Study on the Dynamics of the Tendon/Top Tension Riser System of a Tension-Leg Platform

Abstract In this study, the dynamics of tendon/top tension riser (TTR) system a tension-leg platform (TLP) are investigated through an experiment and by using absolute nodal coordinate formulation (ANCF). First, model test TLP is conducted in water tank Harbin Engineering University to examine motion response dynamic characteristics tendon TTR. The scale ratio set 1: 66.3. Then, on basis ANCF, stiffness, external load, mass matrices element deduced establish equation tendon/riser. Finally, static tendon/TTR analyzed systematically ANCF method. results compared with commercial software results. affected movement environmental load simultaneously. analysis proves effectiveness accuracy method despite low number units, suggesting superiority for calculating tendon/riser field ocean engineering.
