[0002] The umbilical cable is a product used for deep-water oil and gas exploration and development. The umbilical cable is a combination of a cable (power cable or signal cable), an optical cable (single-mode or multi-mode optical cable), and a hydraulic or chemical agent pipe (steel pipe or hose). The umbilical cable of the underwater production system is an important part of the underwater production system. It can not only provide electrical energy and hydraulic channels for the underwater production system, but also provide chemical agent pipelines required for oil and gas field development. At the same time, it can also transmit control signals from the upper module and sensor data of the underwater production system.

[0003] Patent Publication No. CN202268201U discloses an umbilical cable for an underwater production system, which includes a plurality of steel pipe units, a plurality of cable units, a plurality of filling units, and an optical cable unit; wherein the cable units are arranged at the core position, and a core sheath is laid on the outer layer of the cable units to use the cable units as the core; the steel pipe units, filling units, and optical cable units are evenly laid on the outer layer of the core, and an inner sheath is laid on the outer layer of the steel pipe units, filling units, and optical cable units; an armor layer is laid on the outer layer of the inner sheath, and an outer sheath is laid on the outer layer of the armor layer. This layout form makes the strength of the umbilical cable more uniform in all directions, and under the action of various loads, the stress distribution of each unit of the umbilical cable is more reasonable.

[0004] The overall protection structure of the above-mentioned umbilical cable for the underwater production system is less, and the anti-fatigue performance is poor. Therefore, an anti-fatigue umbilical cable for the underwater production system is proposed. Through multi-layer design such as a strengthening layer, a third protective sleeve, and a second inner protective sleeve, and the setting of carbon fiber rods and triangular carbon fiber rods, the anti-fatigue performance of the umbilical cable can be effectively improved.

Arc-shaped support blocks are equidistantly embedded between the second inner protection sleeve and the structure sleeve. A cable is embedded on one side of the arc-shaped support block. Steel pipes are equidistantly embedded inside the second inner protection sleeve and the structure sleeve between the cables. Carbon fiber rods are equidistantly embedded outside the steel pipes and the cables.

[0007] A protection component is sleeved outside the second inner protection sleeve. The protection component is a third protection sleeve sleeved outside the second inner protection sleeve. Second stranded steel wires are equidistantly embedded inside the third protection sleeve. An outer protection layer is sleeved outside the third protection sleeve. A strengthening layer is arranged between the outer protection layer and the third protection sleeve. Triangular carbon fiber rods are equidistantly embedded inside the outer protection layer.

[0008] By adopting the above technical solution, the carbon fiber rods between the structure sleeve and the second inner protection sleeve and the two triangular carbon fiber rods inside the outer protection layer can improve the toughness of the umbilical cable. The first stranded steel wire in the first cable core filler and the second stranded steel wire in the third protection sleeve, as well as the strengthening layer outside the third protection sleeve, can improve the strength of the umbilical cable.

[0009] Specifically, the optical fiber component includes an optical cable. A first inner protection sleeve is sleeved outside the optical cable. A first cable core filler is sleeved between the first inner protection sleeve and the optical cable.

[0010] Specifically, first stranded steel wires are equidistantly embedded inside the first cable core filler.

[0011] Specifically, the first cable core filler is made of polyurethane material. The first inner protection sleeve, the second inner protection sleeve, and the outer protection layer are all made of polyvinyl chloride material.
