Abstract：Thesubseachristmas tree isacriticalpieceofequipmentfordep-seaoilandgasdevelopment.Thetubing hanger， servingasachannelforoilandgasandan electricity，supports thetubingcolumnandseals theannularspacebetween the tubingandcasing，making itacorecomponentofthechristmastree.Itsstructuralstrengthdirectlyimpacts thesafetyofoil andgasproduction.Taking thetubinghangerfromanoilandgasfieldintheSouth China Seaasanexample，andanalyzing foreigntubinghangers，the mainstructuraldimensionsoftheunderwaterchristmastree'stubing hangerweredesigned.Finite elementanalysis was employedtoestablish the finiteelement modelofthetubing hanger，andnumerical simulations were conductedfitatiosringtlwengpocsssaliooalpduciondlcgdcingpe. The results indicated that during the lowering process，the maximum stress of the tubing hanger was 310.43MPa witha maximum deformation of 0.45009mm During the installation process，the maximum stress was 310.43MPa ，with a maximum deformation of 0.40885mm .Under normal production conditions of 69MPa and 64°C ，the maximum stress at the oil outlet of the tubing hanger was 311.13MPa ，with a maximum deformation of 0.58148mm .At 69MPa and 121°C ，the maximum stress was 586.93MPa ，and the maximum deformation was 1.33470mm .The analysis shows that the designed tubing hanger meets thesafetystrengthrequirements，exhibitsminimal deformation，andhasgoodstructuralsafety.This tubing hangerhas beensuccessfullyappliedtoChina'sfrstdomesticallydevelopedunderwaterchristmastreesystem，whichplaysasignificant role in advancing the localization of China's underwater oil and gas production systems.
