The accuracy and conservatism of hydrodynamic analysis on flexible pipes directly affect their fa-tigue performance calculation.This paper focuses on an unbonded flexible pipe and conducts an overall hydrody-namic analysis by OrcaFlex to obtain the load curve.Additionally,it extracts typical wave conditions via wave screening and applies the conditions to the OrcaFlex analysis model for obtaining the load response at various posi-tions of the flexible tube.Finally,the extracted maximum bending moment and tensile force data of the flexible pipe can provide data support for following fatigue performance calculation.
