The bend stiffener is a key accessory nested in the end of the umbilical cable and its main function is to prevent excessive bending and deformation of umbilical cable. Due to the load of the marine environment and the boundary motion of the floater

the bend stiffener section of umbilical cable is often subjected to alternating tension and bending loads which

under the long-term action

will cause fatigue damage. The existing researches tend to focus on the fatigue damage of the umbilical cable’s structure itself. While

the fatigue performance analysis of the bend stiffener structure is less. In this paper

the finite element model of the bend stiffener section of umbilical cable is set up with consideration of the sliding contact between these two structures and the geometric nonlinearity. Furthermore

the time history curve of tension load is obtained through hydrodynamic analysis of the whole configuration. Finally

a method for predicting the service life of the bend stiffener is set up on the basis of Fe-safe fatigue life software. It is concluded through the method that both umbilical cable and the bend stiffener meet the service life requirements and the umbilical cable is damaged first. This method can provide some guidance for the analysis and design of the bend stiffener.
