The invention relates to a manufacturing process of a jacket split type submarine cable pipe. The jacket split type submarine cable pipe comprises jacket pile legs, a split type submarine cable pipe, a top platform and suction piles. The split type components are fixed into a whole and welded and fixed through the fixing unit, the first fixing sleeve and the second fixing sleeve, the structural stability and the installation firmness of the device are further enhanced, installation is carried out in a workshop in the first step to the seventh step, and installation is carried out on site in the eighth step to the eleventh step. The problems of water and soil pollution caused by a large amount of welding slag and scrap iron powder generated by field punching, polishing and welding on an installation site and environmental pollution caused by damage to paint on a part in the installation process of the part can be reduced, the environmental safety is maintained, split type manufacturing and installation are adopted, the quality of finished products is guaranteed while the production cost is reduced, a jacket is used for resisting waves and tidal currents of the split type submarine cable pipe, and the service life of the submarine cable pipe is prolonged.
Description
technical field [0001] The invention relates to the field of offshore working structures, in particular to a jacket split-type submarine cable pipe manufacturing process. Background technique [0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunication transmission. Because submarine cables work on the seabed for a long time, but the seabed is not convenient for manual work, and the submarine cable itself cannot resist the long-term effects of waves and tidal currents. Damage repair is more troublesome, so it plays a vital role in cable protection, so there is a submarine cable protection tube; [0003] The existing submarine cable protection tube is installed on the inner wall of the jacket, and the jacket is fixed on the suction pile. The cost of the overall production of the submarine cable protection tube is high, and it is difficult to ensure the quality. Therefore, split ten submarine cable tubes are used. [0004...
