Description

Technical Field

[0001] The present invention belongs to the technical field of marine oil and gas production equipment, and in particular relates to a 10,000-meter optical-electrical composite cable system for lowering and recovering an underwater blowout preventer. Background Art

[0002] As the most critical well control equipment in the ocean, deepwater drilling blowout preventers not only play an important role in deepwater drilling and completion operations, but more importantly, this equipment is related to marine drilling equipment, marine environment and personal safety.

[0003] Currently, most umbilical winches used in my country for deploying and recovering underwater BOPs use conventional PLC-controlled synchronous cable arrangement. This arrangement is sufficient in shallow waters, where the umbilical cable is deployed and recovered at depths up to 300 meters. However, in deepwater operations, where BOPs can be deployed to depths of up to 10,000 meters, the cumulative errors in PLC-controlled synchronous cable arrangement can easily lead to cable misalignment and single sensor failure, potentially preventing the umbilical cable and underwater BOP from being properly deployed and recovered.

[0004] When lowering and recovering the umbilical cable of a 10,000-meter underwater blowout preventer, the "rope biting" phenomenon is likely to occur during the cable arrangement process because the cable release angle cannot be adjusted in time.

[0005] When lowering and recovering the umbilical cable of a 10,000-meter underwater blowout preventer, the umbilical cable heats up severely due to the long time it takes to lower and recover the cable. The umbilical cable is severely deformed by the heat. The deformed umbilical cable can easily have a great impact on the subsequent cable arrangement and may even break the umbilical cable, seriously restricting the safety of the operation.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The present invention is a 10,000-meter optical-electric composite cable system for lowering and recovering underwater blowout preventers. Figure 1-3As shown, it includes an integrated frame 10, a cable storage winch 1 is connected to one side of the bottom of the integrated frame 10, a cable arranger 2 is also connected to the bottom of the integrated frame 10, the cable arranger 2 is arranged close to the cable storage winch 1, and a second guide pulley 9 and a compensator 6 are also connected to the bottom of the integrated frame 10. A traction winch 4 is connected to the middle of the integrated frame 10, and a first guide pulley 7 is connected to one side of the traction winch 4. The cable storage winch 1 is connected to an umbilical cable 5, and the umbilical cable 5 passes through the cable arranger 2, the second guide pulley 9, the compensator 6, the first guide pulley 7 and the traction winch 4 in sequence. The cable storage winch 1 is located on the left side of the integrated frame 10, with the cable reel 2 located directly in front of the cable storage winch 1. The umbilical cable 5, which is drawn from the cable storage winch 1, is routed to the cable reel 2. A second guide pulley 9 is located to the right of the cable reel 2, and a compensator 6 is located behind the second guide pulley 9. The traction winch 4 is located above and to the right of the second guide pulley 9. The umbilical cable 5, which is drawn from the cable reel 2, is routed to the second guide pulley 9, then from the second guide pulley 9 through the compensator 6 and the first guide pulley 7 to the traction winch 4. From there, the umbilical cable 5 is drawn from the traction winch 4 to the underwater blowout preventer. After frictional tension reduction through the traction winch 4, the first guide pulley 7, the compensator 6, and the second guide pulley 9, the tension on the umbilical cable 5 reaching the cable reel 2 is minimal, ensuring the neat, accurate, and orderly arrangement of the umbilical cable 5 on the cable storage winch 1. This arrangement is compact but slightly higher, making it suitable for use on drilling platforms with limited space. If a decentralized layout is adopted, it is only necessary to remove the integrated frame 10 and place the cable storage winch 1, cable arranger 2, traction winch 4 and compensator 6 in the deck compartment of the drilling operation surface. The passage order of the umbilical cable 5 is the same as that of the compact layout.

[0031] Example 1

[0032] The system also includes a control console 3, which is connected to an electrical control cabinet 8 via pipelines. Both the control console 3 and the electrical control cabinet 8 are connected to the bottom of the integrated frame 10. The control console 3 is also connected to the cable reel 2, traction winch 4, and compensator 6 via pipelines. The control console 3 controls the operation of the entire system. The first guide pulley 7 is located to the right of the control console 3.

[0033] Example 2

[0034] like Figure 4As shown, the cable arranger 2 includes two relatively arranged connecting plates 2-5, the bottoms of the two connecting plates 2-5 are connected with support legs 2-6, the support legs 2-6 are connected to the bottom of the integrated frame 10, and two optical bars 2-1 and a lead screw 2-2 are connected between the two connecting plates 2-5. One side of one of the connecting plates 2-5 is connected with a cable arrangement motor 2-3, and the cable arrangement motor 2-3 is connected to the control console 3 through a pipeline. The output end of the cable arrangement motor 2-3 is connected to one end of the lead screw 2-2 through a coupling, and a cable arrangement pulley assembly 2-4 is connected to the lead screw 2-2, and the cable arrangement pulley assembly 2-4 is connected to the optical bar 2-1. A circular hole 2-7 is opened in the middle of the plate surface of the two connecting plates 2-5, and the optical bar 2-1 is arranged close to the cable storage winch 1, and the circular hole 2-7 matches the umbilical cable 5. Position sensors are connected to both ends of the optical bar 2-1 to monitor the movement of the cable assembly 2-4. This solves the problem of a single sensor failure preventing the umbilical cable 5 from being lowered and recovered. The control console 3 controls the rotation of the lead screw 2-2 via the cable motor 2-3, which in turn drives the movement of the cable assembly 2-4. The two optical bars 2-1 control the movement and guidance of the cable assembly 2-4. The umbilical cable 5 passes through the circular hole 2-7, and the cable assembly 2-4 adjusts the cable angle.

[0035] like Figure 5 As shown, the cable pulley assembly 2-4 includes two supporting plates 2-4-1 arranged opposite to each other, two optical rod sleeves 2-4-8 are connected between the two supporting plates 2-4-1, and the two optical rod sleeves 2-4-8 are sleeved on the optical rod 2-1 in a one-to-one correspondence. A screw sleeve 2-4-9 is also connected between the two supporting plates 2-4-1, and the screw sleeve 2-4-9 is sleeved on the screw 2-2. The two supporting plates 2-4-1 are connected by a rotating rod 2-4-4 It is connected to a pulley frame 2-4-5, a cable pulley 2-4-10 is connected to the pulley bracket 2-4-5, a cable stop rod 2-4-6 is connected to the pulley bracket 2-4-5, the cable stop rod 2-4-6 is arranged around the cable pulley 2-4-10, and the ends of the pulley bracket 2-4-5 are connected to the first cable damage prevention pulley 2-4-7, and the board surfaces of the two support plates 2-4-1 are provided with cable threading holes 2-4-2, and the cable threading holes 2-4-2 match the umbilical cable 5. After the umbilical cable passes through the cable threading hole 2-4-2, it passes around the cable arrangement pulley 2-4-10. The pulley bracket 2-4-5 rotates through the rotating rod 2-4-4. As the 10,000-meter optical-electric composite cable of the underwater blowout preventer is recovered and lowered, the umbilical cable 5 on the drum of the cable storage winch 1 is continuously increased or lowered. The angle of the pulley bracket 2-4-5 of the cable arrangement pulley assembly 2-4 is corrected in real time, realizing precise cable arrangement. The cable arrangement and entry angle is adjusted mechanically by using the first cable damage prevention pulley 2-4-7. Compared with the angle sensor, it has a simple structure and no cumulative error.

[0036] Both support plates 2-4-1 have arc-shaped limit holes 2-4-3 on their surfaces. Limit pins 2-4-11 are connected to both sides of the pulley bracket 2-4-5. The limit pins 2-4-11 match the limit holes 2-4-3. The limit pins 2-4-11 are inserted into the arc-shaped limit holes 2-4-3. When the pulley bracket 2-4-5 rotates, the limit holes 2-4-3 and the limit pins 2-4-11 cooperate to limit it, preventing it from rotating indefinitely.

[0037] Example 3

[0038] like Figure 6 As shown, the second guide pulley 9 includes a guide pulley frame 9-5, the bottom of which is connected to a support leg 9-1, which is connected to the integrated frame 10, and a single pulley 9-2 is connected to the guide pulley frame 9-5. The ends of the guide pulley frame 9-5 are connected to a second cable damage prevention pulley 9-3, which is arranged around the single pulley 9-2. The guide pulley frame 9-5 is also connected to a plurality of first rope blocking rods 9-4, which are arranged around the single pulley 9-2, and the single pulley 9-2 matches the umbilical cable 5. The guide pulley frame 9-5 has a centrally symmetrical structure, and the second cable damage prevention pulley 9-3 is arranged in the cable outlet direction of the guide pulley frame 9-5, which solves the wear problem of the umbilical cable 5 due to swinging.

[0039] Example 4

[0040] like Figure 7 As shown, the compensator 6 includes two relatively arranged connecting plates 6-11, the bottoms of the two connecting plates 6-11 are connected to the first support legs 6-10, the first support legs 6-10 are connected to the integrated frame 10, and a guide rail 6-3 is connected between the two connecting plates 6-11, and one side of one connecting plate 6-11 is connected to the accumulator 6-2 and the hydraulic cylinder 6-1, the accumulator 6-2 is connected to the hydraulic cylinder 6-1 through a pipeline, the hydraulic cylinder 6-1 is connected to the control console 3 through a pipeline, and the push rod 6-4 of the hydraulic cylinder 6-1 is connected to the first pulley frame 6-6 through the connecting plate 6-11, and the pulley 6-12 is connected to the first pulley frame 6-6, and a plurality of first rope-blocking rods 6-5 are also connected to the first pulley frame 6-6, and the first rope-blocking rods 6-5 are arranged around the pulley 6-12, and the pulley 6-12 is matched with the umbilical cable 5, and a through hole 6-14 is provided on the plate surface of the connecting plate 11 opposite to the hydraulic cylinder 6-1. The compensator 6 keeps the system's umbilical cable 5 taut, reducing peak tension within the system. It also limits reverse tension on the umbilical cable 5 during emergency braking. The first pulley frame 6-6 slides back and forth along the length of the guide rail 6-3, driven by a push rod 6-4. The push rod 6-4 is driven by a hydraulic cylinder 6-1. When the push rod 6-4 retracts, the accumulator 6-2 is compressed. Conversely, when the push rod 6-4 extends, the accumulator 6-2 is in its neutral position.

[0041] Buffer pads 6-7 are connected to opposite sides of the first pulley frame 6-6. A locking plate 6-8 is connected to one side of the first pulley frame 6-6. One end of the locking plate 6-8 is connected to a locking hole 6-9. A matching locking plate 6-13 is connected between the two connecting plates 6-11. A matching locking buckle is connected to the surface of the matching locking plate 6-13, and the matching locking buckle matches the locking hole 6-9. The buffer pads 6-7 prevent direct collision between the first pulley frame 6-6 and the connecting plate 6-11. When the locking hole 6-9 overlaps with the matching locking buckle, a bolt can be passed through to fix the relative position of the first pulley frame 6-6. After the first pulley frame 6-6 is locked, the pulley 6-12 can be used as a guide pulley. The first pulley frame 6-6 can also be released to use as a compensator 6.

[0042] Example 5

[0043] like Figure 8 As shown, the traction winch 4 includes a frame 4-1, which is connected to the middle of the integrated frame 10. One side of the frame 4-1 is connected to the first guide pulley 7 via a connector. A driving drum 4-3 and a driven drum 4-4, arranged side by side, are connected to the frame 4-1. Two variable-frequency motors 4-6 are connected to the side walls of the frame 4-1. Both variable-frequency motors 4-6 are connected to the driving drum 4-3 and the driven drum 4-4, respectively, via a reducer. Both the driving drum 4-3 and the driven drum 4-4 are provided with a cable trough that mates with the umbilical cable 5. The control console 3 controls the activation of the two variable-frequency motors 4-6, thereby controlling the rotation of the driving drum 4-3 and the driven drum 4-4. The umbilical cable 5 is laid in the cable trough and wound around the driving drum 4-3 and the driven drum 4-4. The diameter of the cable trough on the two drums gradually increases, which can better match the cable arrangement and effectively reduce the heating problem of the umbilical cable.

[0044] A plurality of rear cable rods 4-5 are connected to the frame 4-1. The rear cable rods 4-5 are arranged around the active roller 4-3 and the driven roller 4-4. The end of the frame 4-1 is connected to the third cable damage prevention pulley 4-2.

[0045] The working principle of the 10,000-meter optical-electric composite cable system for lowering and recovering underwater blowout preventers of the present invention is as follows:

[0046] Depending on the on-site operating space, the need for an integrated frame 10 is determined. The umbilical cable 5 on the drilling deck is introduced by the storage winch 1 to the cable reel 2 located directly in front. It then passes through the cable reel 2 to the second guide pulley 9 and then to the compensator 6. The compensator 6 tightens the umbilical cable 5 for the entire operating system. The umbilical cable 5 is then drawn out from the compensator 6, passes through the first guide pulley 7, reaches the traction winch 4, and finally is drawn out by the traction winch 4 to the underwater blowout preventer. After friction-induced tension reduction through the traction winch 4, the first guide pulley 7, the compensator 6, and the second guide pulley 9, the umbilical cable 5 reaches the cable reel 2 with minimal tension, ensuring the neat, accurate, and orderly arrangement of the umbilical cable 5 on the storage winch 1.

[0047] The present invention lowers and recovers a 10,000-meter optoelectronic composite cable system for underwater blowout preventers. Multiple sets of cable damage prevention pulleys are arranged at the cable entry and exit directions of the cable arranger, second guide pulley, compensator, and traction winch, solving the wear problem of the umbilical cable swinging. The angle of the pulley bracket of the cable arranger pulley assembly is corrected in real time to achieve precise cable arrangement. The cable entry angle is adjusted mechanically by using the first cable damage prevention pulley. Compared with the angle sensor, the structure is simple and there is no cumulative error.
