The invention relates to a limit control system for a delivery pipeline terminal, which is provided with an underframe, a limit device, a sensor and a terminal limit control system, wherein the limit device is arranged on the underframe; the sensor is arranged on the limit device and is connected with the terminal limit control system; and the terminal limit control system is arranged on a delivery pipeline to control the terminal of a seabed pipeline on the delivery pipeline to be positioned accurately. In the limit control system, the delivery of the seabed pipeline on the longitudinal delivery pipeline can be controlled automatically, so that the terminal of the seabed pipeline on the longitudinal delivery pipeline is positioned accurately; the labor strength of operators is reduced, the work efficiency is improved, and the safety and reliability of the longitudinal delivery pipeline of the seabed pipeline are improved.
