The subsea control module(SCM)is the core unit of the subsea production equipment,and as the operating water depth increases,special tools must be used to achieve reliable installation.The locking and unlocking process of QSCM Ⅱ generation underwater control module produced by Chongqing Avant-garde is analyzed,and a special tool for emergency unlocking is designed to realize emergency unlocking under water.On this basis,the finite element analysis model of the drive rod of the emergency unlocking tool is constructed,and the strength of the drive rod and the connection thread is analyzed.The results show that the maximum stress of the driving rod is 91.736 MPa,which is much lower than the yield strength of the material 517.000 MPa.The maximum contact pressure of the threaded connection is 24.176 MPa at the end thread,which is less than the allowable extrusion stress of the threaded material.SCM emergency unlock tool for debugging,meet the design requirements,and provide ideas for the future design optimization of underwater control module and related products.
