Abstract

The invention discloses a mud contact point monitoring device and a monitoring method in the process of laying submarine pipelines, which relate to the field of laying submarine pipelines. The invention solves the problem of low information transmission efficiency in the existing submarine pipeline laying underwater cableless monitoring device, and the problem that the cable of the underwater cable monitoring device is easily damaged in complex sea areas. The crawler drive unit of the middle crawler mechanism of the invention is installed at the lower end of the middle support frame, the upper end of the middle support frame is connected with the frame, the crawler drive unit of the side crawler mechanism is installed at one side of the side support frame, and the side support frame is connected with the frame. The two pan-tilts are arranged on the left and right sides of the submarine pipeline respectively, the upper end of the pan-tilt is connected with the driving module, and the driving module is installed on the frame. The invention is used to monitor the position of the mud entry point of the submarine pipeline, and make timely adjustments to the laying position of the pipeline through the video information fed back by the monitoring device, so as to ensure that the submarine pipeline is laid on the predetermined track, so that the entire submarine pipeline laying construction can be carried out smoothly .

Description

technical field [0001] The invention relates to the field of submarine pipeline laying, in particular to a monitoring device and method for monitoring mud contact points during the laying of submarine pipelines. Background technique [0002] Submarine pipeline is the main component of the development and production system of offshore oil and gas fields. It is an oil and gas transportation tool connecting oil wells and platforms, platforms and onshore storage and transportation facilities. The location of submarine pipelines determines the structural safety and use of submarine pipelines. life. [0003] Due to the complexity and diversity of the submarine terrain, there are some dangerous areas such as rugged or soft mud. In order to ensure the safety of the submarine pipeline, it is necessary to design a reasonable and safe submarine pipeline laying track in advance. If the pipeline deviates from the preset laying track, it will affect the structural safety of the submarine...
