This paper evaluates the hydrodynamic performance of a damaged ISSC TLP which is caused by a tendon disconnection. Performance evaluation of a TLP with a disconnected tendon in a rough sea state is the major aim of this paper. First off, modeling of a platform in a proper sea state is carried out and then after disconnecting one of the tendons, the transient effect on the other tendons is assessed. Also, the steady state forces are validated using analytical results. Additionally, time history of heave and surge accelerations, TLP six degree of freedom motions and also tendon forces are determined in regular waves. In order to assess the hydrodynamic performance of the platform, a numerical simulation is conducted, using multipurpose boundary element software. At last the analysis shows that the modeling of a damaged platform is carried out properly and also the conclusion can be drawn that it is possible to evaluate the performance of a damaged platform in Regular waves.
Keywords: ISSC TLP, Tendon Disconnection, Boundary Element, Diffraction theory
