Description

Technical Field

[0001] The utility model relates to the technical field of umbilical cable anchoring, in particular to an anchoring device for an underwater production system. Background Art

[0002] The main functions of the umbilical cable are to provide power for the underwater production system, provide a hydraulic channel for the control of the underwater production system, provide chemical agent pipelines required for oil and gas field development, transmit control signals of the upper module and sensor data of the underwater production system. At present, the umbilical cable is anchored by a specific limit collar and a tapered sleeve structure. The tapered sleeve is used to sleeve the outer sheath of the umbilical cable, providing a basic positioning for the entire anchoring structure.

[0003] The connection method of the existing anchoring device is generally sleeve installation. In the case of long-term use, the anchoring structure is extremely likely to need to be replaced due to serious damage and other problems. However, the disassembly and replacement method of the existing sleeve connection is extremely cumbersome, time-consuming and laborious. Therefore, an anchoring device for an underwater production system is proposed, which uses a clamp docking method to replace the sleeve assembly, so as to ensure the convenience of later disassembly and replacement.

[0009] When the ferrule assembly needs to be replaced, the semi-circular flange B can be disassembled from the top of the connection assembly, and the bolts connected to the connection hole B can be disassembled. The semi-circular snap ring C and the semi-circular snap ring D can be directly disassembled and replaced, with convenient operation.

[0010] When the connection assembly needs to be replaced, the bolts connected to the connection hole A can be disassembled, and then the semi-circular flange A and the connection part can be disassembled by bolts, so as to achieve the effect of disassembling and replacing the semi-circular snap ring A and the semi-circular snap ring B.

[0011] Specifically, the ferrule assembly is located at the top of the connection assembly.

[0012] By adopting the above technical solution, the ferrule assembly is used to cooperate with the umbilical cable for ferrule fastening.

[0015] Specifically, the semi-circular snap ring C and the semi-circular snap ring D are opposite in position. Connection holes B are evenly provided from top to bottom on both side surfaces of the semi-circular snap ring C and the semi-circular snap ring D. Semi-circular flanges B are provided at the bottoms of the semi-circular snap ring C and the semi-circular snap ring D.

[0016] By adopting the above technical solution, the semi-circular limit ferrule A and the semi-circular limit ferrule B are used to cooperate with the umbilical cable for limit clamping. Through the connection holes B, it is convenient to connect and fix the semi-circular snap ring C and the semi-circular snap ring D through bolts.
