Docking control method and system for intelligent immersed tube carrying and mounting integrated ship

The invention discloses a docking control method and system for an intelligent immersed tube carrying and mounting integrated ship. The method comprises the following steps: selecting an opening mode of a side thrust driving unit according to real-time water flow information outside an integrated ship, calculating the side thrust power required for resisting the transverse water flow force according to the real-time water flow information as anti-transverse-flow side thrust power Pc, starting the side thrust driving unit, and controlling the working power of the side thrust driving unit in real time according to the Pc; according to the position deviation of the integrated ship, calculating the deviation correction side thrust power required for correcting the position deviation, and on the basis of the anti-transverse-flow side thrust power Pc, and controlling and adjusting the working power of the side thrust driving unit in real time according to the deviation correction side thrust power till the real-tim
