Abstract

A new nonlinear model of TLP's tendon is presented and its VIV response in effect of current load is simulated considering the hull's motions effects on boundary condition and tension of tendon. Different tensions are considered to affect the VIV response. The Morison equation is used to solve the y-direction time-dependent force exerted on the tendon moving in the fluid. The CFD program FLUENT is used to solve the current force of tendon using 2D model. The finite element method is used to figure out the nonlinear response of tendon. The results show that the changing of tension has significant effects to tendon's VIV response.
