Abstract

This paper presents results of two-phase flow numerical simulations of the dynamic behaviour of a Tension Leg Platfrom (TLP). The Computational Fluid Dynamics (CFD) simulations were based on the volume of fluid (VOF) method implemented in the CFD code STAR-CCM+. The TLP's rigid body motions and the effect of tendons were simulated by means of an overset grid and massless spring lines, respectively. The global response and tendon tensions computed by the CFD code were found to be in good agreement with experimental measurements. CFD tools provided detailed results of the effect of wave impact including wave-in-deck loads and were able to predict some rare features such as tendon slackness and ringing response.
