In order to provide efficient and reliable method for structural design and optimization of upper assembly and lower assembly of a free standing hybrid riser, a numerical calculation model and model test device for the upper assembly and lower assembly of a free-standing hybrid riser were established independently based on similarity criterion and correlative elastic-plastic mechanics theories and methods. The static and dynamic numerical calculations and corresponding tests for the upper assembly and lower assembly of a free-standing hybrid riser were carried out. The results show that the deviation between numerical simulation results and experimental results is less than 6.83%, and the dynamic test results coincide with the dynamic results of numerical simulation. The results of the above study demonstrate that the accuracy and reliability of numerical results for static and dynamic responses of the upper assembly and lower assembly and suggestions on further optimization for upper assembly and lower assembly of a free standing hybrid riser are given based on numerical simulation and test results. These results provide guidance for structural optimization of the upper assembly and lower assembly of a free-standing hybrid riser.
