The transfer characteristic of the CT’s axial load is necessarily investigated for its safety operation. In this study, a mechanical model of the coupled tube systems is described using micro element method. To analyse the effects of ocean loads, an experimental downsized platform is built. A physical vibration exciter is used to simulate the SCR’s lateral vibration, and then the axial load and its transfer efficiency of the CT are obtained under the excitation frequencies of 3, 6, 9 Hz and excitation forces of 30, 50, 70 N. Experimental results show that the excitation forces and excitation frequencies within certain ranges would promote the transmission of the axial force of the inner pipe. The force-outs under excitation frequencies and excitation forces are greater than that under no force excitation, and the transfer efficiencies of axial force will increase with the growth of the excitation forces and excitation frequencies.
