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.
