Abstract： The locking mechanism is the key part of subsea control module (SCM). It is of great practical significance to calculate the maximum thrust provided by remote operated vehicle (ROV) in operation process. The locking mechanism structure is analyzed, and the dynamic analysis method of SCM locking mechanism is researched. By analyzing the simulation results, the maximum thrust provided by ROV needed for operation process is obtained. The feasibility of locking mechanism structure design is verified by analysis results, and the necessary basis for ROV selection can be provided.
