Dynamic Response Analysis on Different Types of TLPS

Abstract

Different structural forms of TLP have different capacities and different scopes of application. Each type of TLP is globally designed. The hydrodynamic parameters and dynamic responses of different types of TLPs are studied considering the effect of different directions of wave and tendon stiffness. The unsteady potential flow theory and boundary element method are used to analyze flow field and hydrodynamic calculation. The software AQWA suite which is a set of advanced hydrodynamic analysis programs is used to perform the numerical simulation of TLP motion response. The results show that the dynamic responses of different types of TLPs are observably different. Changes of wave directions and added stiffness from tendons have certain effect on the motion response of a TLP.
