Abstract
Tension-leg platform (TLP) is a very complex rigid-flexible coupling multi-body system. The failure of some tendons will induce continuous failure and lead to the platform capping. In this paper, a mechanistic study of a typical TLP under tendon breakage is addressed. The time-domain nonlinear results for the floating hull coupled with mooring lines were obtained to analyse the equilibrium position and amplitude of the steady-state response. The change laws of the balance positions of the motions and the reasons for the changes in the movement amplitudes were explored. By changing the wave parameters, the change rules of nonlinear motions and the damage caused by the change in the natural period were investigated.
