Description

Technical Field

[0001] The invention relates to a floating oil storage and offloading vessel with an external fireproof cabin structure. Background Art

[0002] A floating production, storage and offloading (FPSO) vessel acts like an offshore oil and gas processing plant, processing a mixture of oil, gas, and water from oil wells into qualified crude oil or natural gas. The finished crude oil is stored in cargo tanks and, when reserves reach a certain level, is transported to shuttle tankers via an external transfer system. FPSOs are equipped with crude oil processing equipment, and some are anchored to the sea surface using a single-point mooring system. An FPSO (Floating Production, Storage and Offloading) vessel typically integrates with a drilling platform or subsea production system to form a complete system for oil production, crude oil processing, storage, and offloading. Its operating principle is to receive crude oil extracted from subsea wells via subsea pipelines, process it onboard, store it in cargo tanks, and finally transfer it to shuttle tankers via an offloading system. Existing FPSOs store crude oil in cargo tanks, but these tanks lack fireproofing. If a fire is not extinguished promptly, significant economic losses could result. Therefore, a FPSO with an external fireproof tank structure has been proposed to address this issue. Summary of the Invention

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] like Figure 1-10 As shown, a floating oil storage and offloading vessel with an external fireproof cabin structure includes: a cabin 1; a hull 2; a set of spray faucet mechanisms are respectively provided at the upper ends of the outer side walls of the cabin 1; a sliding faucet mechanism is provided at the rear end of the spray faucet mechanism; and an automatic door closing mechanism is provided at the cabin door 5; wherein, the cabin 1 is provided at the rear end of the upper end of the hull 2, and a water storage tank 3 is provided on the upper end surface of the cabin 1; and a fire detector 4 is provided on each of the side walls of the cabin 1.

[0038] Specifically, the jet faucet mechanism includes multiple first jet faucets 9, a connecting plate 6 is connected to each side of the upper end of the side wall of the cabin 1, a mounting plate 7 is connected between the two connecting plates 6, and multiple first jet faucets 9 are connected to the front end of the mounting plate 7. The upper ends of the multiple first jet faucets 9 are connected to the first water pipe 8. When the fire detector 4 detects a fire, it sends a signal to the controller, and the controller sends an electrical signal to the first water pump and the second water pump to make the first water pump and the second water pump work, so that the water in the water storage tank 3 is sprayed out from the first jet faucet 9. Because the first jet faucet 9 is flat, the sprayed water is in the form of a water wall, so the multiple first jet faucets 9 form a water wall on the outer wall of the cabin 1 to prevent the fire from advancing into the cabin 1.

[0039] Specifically, the sliding faucet mechanism includes a screw rod 11. The upper ends of the two connecting plates 6 are each connected to a shaft connector 17. The screw rod 11 is connected between the two shaft connectors 17. A screw nut 12 is connected to the screw rod 11. The lower side of the screw nut 12 is connected to the second jet faucet 13. The front side of the second jet faucet 13 is connected to the second water pipe 14. A through slot 16 is defined in the mounting plate 7 below the screw rod 11. The lower end of the second jet faucet 13 passes through the through slot 16. A limiting groove 18 is defined at the rear end of the upper end of the mounting plate 7. The lower end of the L-shaped connecting plate 15 slides within the limiting groove 18, and the upper end is connected to the screw nut 12. Both ends of the first water pipe 8 can be connected to a water source. Each end of the first water pipe 8 is connected to a first water pump, which is connected to the water storage tank 3. The second water pipe 14 is connected to the second water pump, which is connected to the water storage tank 3. The screw rod 11 is connected to a drive motor. The controller sends a signal to the first water pump and the second water pump at the same time as sending a signal to the driving motor. The driving motor rotates to drive the screw rod 11 to rotate. The forward rotation of the driving motor drives the screw rod 11 to rotate forward, causing the screw rod nut 12 to move to the right. The reverse rotation of the driving motor drives the screw rod 11 to reverse, causing the screw rod nut 12 to move to the left, thereby driving the second spray faucet 13 to move left and right while spraying water. When multiple first spray faucets 9 are individually damaged, the second spray faucet 13 can achieve a better fire prevention effect.

[0040] Specifically, the automatic door closing mechanism includes a hatch plate 19, a door strip 20 is connected to the right side of the inner wall of the hatch door 5, and the upper and lower ends of the door strip 20 are respectively connected to a door ring 21, and the right side of the inner wall of the hatch plate 19 is connected to a bolt rod 22, and the upper and lower ends of the bolt rod 22 are movably connected to the two door rings 21; the upper end of the side wall of the door strip 20 is connected to a sliding member 23, and the upper end of the bolt rod 22 is connected to a first bracket 24, and the first bracket 24 is connected to a roller 25, and the roller 25 rolls on the sliding member 23. A limited opening 26 is provided at the starting point of the upper end surface of the sliding member 23; the upper end of the outer wall of the hatch door 5 is connected to a horizontal The cross plate 28 has two columns 29 connected to its lower end. A weight 27 is slidably connected to the column 29 on the left side of the cross plate 28. A second bracket 37 is connected to each end of the upper end of the cross plate 28. Each of the two second brackets 37 is connected to a pulley 30. A through-hole 35 is defined on the outer sides of the two pulleys 30 at each end of the cross plate 28. A rotating member 33 is connected to the through-hole 35 at the right end of the cross plate 28. A first pull rope 31 is connected to the weight 27. The first pull rope 31 passes upward around the two pulleys 30, through the rotating member 33, and then connects to the hatch panel 19. A rotating groove 36 is defined in the through-hole 35 at the right end of the cross plate 28. A rotating block 34 is connected to the outer wall of the rotating member 33, which is rotatably connected to the rotating groove 36. The rotating member 33 is L-shaped. The front end of the upper end of the cabin 1 is connected to the connecting frame 38, the weight 27 is connected to the second pull rope 32, the second pull rope 32 is connected to the connecting frame 38 upward, and the sliding faucet mechanism at the upper end of the front side wall of the cabin 1 is connected to a blade 39. The blade 39 is connected to the front side of the second jet faucet 13. When the drive motor receives a signal and works, the second jet faucet 13 moves left and right. The blade 39 is connected to the sliding faucet mechanism at the upper end of the front side wall of the cabin 1. The movement of the second jet faucet 13 drives the blade 39 to move, so that the blade 39 cuts the second pull rope 32. The second pull rope 32 breaks and loses its pulling force on the weight 27, so that the weight 27 falls downward. The weight 27 falls downward and pulls the first pull rope 31, so that the first pull rope 31 pulls the hatch panel 19, so that the hatch panel 19 is closed. Closed; the first pull rope 31 passes through the rotating part 33 and is connected to the hatch panel 19, which can make the first pull rope 31 smoother when pulling the hatch panel 19 and will not get stuck due to angle problems when pulling; when the hatch panel 19 is open, the roller 25 is located in the limit opening 26 of the sliding member 23. When the first pull rope 31 pulls the hatch panel 19, the roller 25 disengages from the limit opening 26 and slides downward toward the sliding member 23, which can add a downward movement force to the hatch panel 19, so that the hatch panel 19 can be closed better.

[0041] Working principle: When the fire detector 4 detects a fire, it sends a signal to the controller, which then sends an electrical signal to the first and second pumps, causing them to operate and spray water from the water storage tank 3 from the first jet faucet 9. Because the first jet faucet 9 is flat, the water sprayed out forms a water wall. Therefore, multiple first jet faucets 9 form a water wall on the outer wall of the cabin 1, which can prevent the fire from advancing into the cabin 1. The controller sends signals to the first and second pumps and also to the drive motor. The drive motor rotates, driving the screw 11. Forward rotation of the drive motor drives the screw 11 forward, causing the screw nut 12 to move to the right. Reverse rotation of the drive motor drives the screw 11 reversely, causing the screw nut 12 to move to the left, thereby driving the second jet faucet 13 to move left and right while spraying water. If individual first jet faucets 9 are damaged, the second jet faucet 13 can achieve a better fire prevention effect. When the driving motor receives the signal and works, the second jet faucet 13 moves left and right. A blade 39 is connected to the sliding faucet mechanism at the upper end of the front side wall of the cabin 1. The movement of the second jet faucet 13 drives the blade 39 to move, so that the blade 39 cuts the second pull rope 32. The second pull rope 32 breaks and loses the pulling force on the weight 27. The weight 27 falls downward. The falling weight 27 pulls the first pull rope 31, so that the first pull rope 31 pulls the hatch panel 19, so that the hatch panel 19 is closed. Closed; the first pull rope 31 passes through the rotating part 33 and is connected to the hatch panel 19, which can make the first pull rope 31 smoother when pulling the hatch panel 19 and will not get stuck due to angle problems when pulling; when the hatch panel 19 is open, the roller 25 is located in the limit opening 26 of the sliding member 23. When the first pull rope 31 pulls the hatch panel 19, the roller 25 disengages from the limit opening 26 and slides downward toward the sliding member 23, which can add a downward movement force to the hatch panel 19, so that the hatch panel 19 can be closed better.
