Description

Technical Field

[0001] This application relates to the field of oil loading and unloading equipment technology, and in particular to oil loading and unloading devices. Background Technology

[0002] With energy demand increasing daily, the development of offshore oil and gas resources is attracting more and more attention. Specialized equipment for drilling, development, and production of offshore oil and gas resources has become key equipment in energy development, and its demand is rising significantly. The rapidly developing offshore oil and gas equipment industry has become an important sector of my country's energy equipment industry, possessing extremely significant economic value and strategic importance. Floating production storage and offloading (FPSO) units are oil storage devices used for storage and transportation during offshore oil well extraction. They are generally designed with storage tanks in a ship-like shape to facilitate floating on the water surface.

[0003] Then, when existing oil storage and offloading (OSA) devices are used in deep-sea areas, they are prone to shaking due to large waves, and their wave resistance is not strong, making them very inconvenient to use. Utility Model Content

[0004] Therefore, it is necessary to provide an oil storage and unloading device to address the problem that oil storage and unloading devices are prone to shaking during use due to large waves, have weak wave resistance, and are very inconvenient to use.

[0005] An oil loading and unloading device, comprising:

[0006] The hull is equipped with a water-containing cavity;

[0007] A pumping and draining mechanism is installed on the hull, which is capable of injecting water into the water-containing cavity or draining water from the water-containing cavity.

[0008] A balancing mechanism is installed on the hull. There are two sets of balancing mechanisms, which are used to adjust the buoyancy distribution on both sides of the hull along a first direction, where the first direction is the left-right direction of the hull.

[0009] The dewatering mechanism increases the hull's weight by filling the water-filled chamber or discharging water from the chamber, thus reducing the hull's weight. This mechanism allows for flexible filling and discharging, dynamically adjusting the hull's draft and center of gravity to adapt to different wave intensities. The balancing mechanism adjusts the buoyancy distribution on both sides of the hull to actively counteract the hull's heeling moment, precisely adapting to various sea conditions such as cross waves and oblique waves.

[0010] In one embodiment, the pumping and drainage mechanism includes:

[0011] Water pipe, the water pipe connecting the water-containing cavity and the outside;

[0012] A water pump, mounted on the hull, is capable of injecting external water into the water-receiving cavity, and / or, the water pump is capable of draining water from the water-receiving cavity to the outside.

[0013] In rough seas, while the balancing mechanism is operating, water pumps can be activated to draw seawater into the water-bearing chamber. This increases the weight of the oil loading and unloading equipment, deepens the draft, lowers the ship's center of gravity, and enhances the stability of the equipment against wind and waves. When it is necessary to reduce load or relocate the work area, the water pumps in the drainage mechanism reverse their operation to expel seawater from the water-bearing chamber, flexibly adjusting the ship's draft and buoyancy balance.

[0014] In one embodiment, the cross-sectional shape of the water-containing cavity is the same as that of the hull in the plane defined by the first and second directions. The second direction is the height direction of the hull, which is beneficial to increasing the volume of the water-containing cavity to increase the seawater capacity in the water-containing cavity.

[0015] In one embodiment, the balancing mechanism includes:

[0016] The drive assembly is located on one side of the hull;

[0017] An adjustment plate is connected to the drive assembly, which is configured to drive the adjustment plate to reciprocate along a second direction and to drive the adjustment plate to swing around a third direction, wherein the second direction is perpendicular to the first direction and the third direction is parallel to the forward direction of the hull.

[0018] The balancing mechanism adjusts the position of the adjusting plate relative to the hull using a drive assembly based on the hull's angle, adapting the plate's position to the direction of wind and waves. By positioning the adjusting plate relative to the hull at different locations, it regulates the buoyancy distribution on both sides of the hull, counteracting the hull's heeling moment and actively restoring horizontal balance.

[0019] In one embodiment, the driving component includes:

[0020] A first guide member is disposed on one side of the hull, and the first guide member has a first guide groove extending along the second direction;

[0021] The driving component is disposed on the first guide component;

[0022] A connecting screw is disposed in the first guide member along the second direction, and the output end of the driving member is connected to the connecting screw.

[0023] A first slider is slidably disposed in the first guide groove. The first slider is sleeved on the connecting screw and threadedly connected to the connecting screw. The adjusting plate is connected to the first slider. The driving member is configured to drive the connecting screw to rotate, so that the first slider reciprocates in the first guide groove along the second direction, thereby driving the adjusting plate to move along the second direction.

[0024] The drive assembly can drive the adjustment plate to reciprocate along the second direction.

[0025] In one embodiment, the driving component further includes:

[0026] The second guide member has a second guide groove extending along the second direction. The second guide member and the first guide member are parallel and spaced apart on one side of the hull along the third direction.

[0027] The second slider is slidably disposed in the second guide groove. The second slider is connected to the adjustment plate. The first slider and the first slider together support the adjustment plate.

[0028] A guide rod is disposed in the second guide groove along the second direction, and the guide rod passes through the second slider.

[0029] The second slider, together with the first slider, supports the adjusting plate, which helps maintain the stability of the adjusting plate extending in the first direction, thereby improving the accuracy of adjusting the hull angle.

[0030] In one embodiment, the driving component further includes:

[0031] A gear is rotatably connected to the first slider or the second slider, and the gear is fixedly connected to the adjusting plate;

[0032] A rack extends along the second direction and is disposed on the hull, and the gear meshes with the rack.

[0033] This drive assembly facilitates the simultaneous movement of the adjustment plate along a second direction while driving the adjustment plate. Through a rack and pinion structure, the drive assembly precisely adjusts the angle of the adjustment plate to regulate the buoyancy distribution on both sides of the hull, counteracting the hull's heeling moment and actively restoring horizontal balance. This device is adaptable to varying wave intensities.

[0034] In one embodiment, the balancing mechanism further includes:

[0035] A sway sensor is electrically connected to two drive components of the two sets of the balancing mechanisms.

[0036] In this way, the drive components on one or both sides of the hull can be driven to work separately or simultaneously according to the sensing results of the shaking sensor, which is beneficial to accurately control the angle of the adjustment plates located on the left and right sides of the hull.

[0037] In one embodiment, the hull is provided with an oil storage chamber, and the oil loading and unloading device further includes:

[0038] At least one first partition extends in the oil storage cavity along a third direction and is configured to divide the oil storage cavity into at least two sub-chambers arranged along the first direction.

[0039] And / or, at least one second partition extending along the first direction and disposed in the oil reservoir, the second partition being configured to divide the oil reservoir into at least two sub-chambers arranged along the third direction.

[0040] This oil loading and unloading device facilitates the movement of oil within the sub-chambers when the ship's hull is rocking in wind and waves, reducing the impact of the oil's inertial motion on the overall hull movement.

[0041] In one embodiment, the first partition is provided with a first through hole, which is located near the bottom of the hull;

[0042] And / or, the second partition is provided with a second through hole, which is located near the bottom of the hull along a second direction.

[0043] The structure of the first and second baffles, the first through hole and the second through hole creates an oil storage chamber that is wider at the top and narrower at the bottom, with a deeper oil level in the middle. When the hull is rocked by wind and waves, the oil automatically flows through the first and second through holes to the sub-chamber in the middle, aided by gravity. By utilizing the principle of "mass concentrated at the center of the hull", the hull sway amplitude is reduced, and the self-stabilizing effect, similar to that of a "liquid damper", is used to suppress swaying.

[0062] See Figure 1 , Figure 1 A schematic diagram of the structure of an oil loading and unloading device provided in one embodiment of this application is shown.

[0063] like Figure 1As shown, this embodiment provides an oil loading and unloading device. The device includes a hull 100 and a pumping / draining mechanism 200. The hull 100 has a water-containing cavity 110, and the pumping / draining mechanism 200 is mounted on the hull 100. The pumping / draining mechanism 200 can either inject water into the water-containing cavity 110 or drain water from the cavity, thereby reducing the weight of the hull 100. This pumping / draining mechanism 200 allows for flexible filling and emptying, dynamically adjusting the draft and center of gravity of the hull 100 to adapt to different wave intensities.

[0064] In this embodiment, the first direction is the left-right direction of the hull 100, which is defined as the Y direction; the second direction is the height direction of the hull 100, which is defined as the Z direction; and the third direction is the front-back direction of the hull 100, which is defined as the X direction. The X, Y, and Z directions are all perpendicular to each other.

[0065] Specifically, the oil loading and unloading device can be used in environments such as rivers, lakes, or the sea. The corresponding pumping and drainage mechanism 200 can pump and drain river water, lake water, or seawater. In this embodiment, the oil loading and unloading device is used in the sea.

[0066] The oil loading and unloading device also includes a balancing mechanism 300. The balancing mechanism 300 is mounted on the hull 100, and there are two sets of balancing mechanisms 300. These two sets of balancing mechanisms 300 are used to adjust the buoyancy distribution on both sides of the hull 100 along a first direction Y, where Y is the port and starboard direction of the hull 100. This oil loading and unloading device actively counteracts the heeling moment of the hull 100 by adjusting the buoyancy distribution on both sides of the hull 100 through the balancing mechanism 300, thus precisely adapting to various sea conditions such as transverse waves and oblique waves. The two sets of balancing mechanisms 300 are located on both sides of the hull 100 to facilitate buoyancy adjustment on both sides of the hull 100.

[0067] In addition, the oil loading and unloading device also includes a top cover 600, on which a water pump and a sway sensor 330 are fixed. A vent valve 610 is provided on the top cover 600 to maintain a balance between the internal and external air pressure of the oil storage chamber 140.

[0068] The upper cover 600 is also provided with an oil inlet 620 and an oil outlet 630 to facilitate the smooth addition or removal of oil into the oil storage chamber 140. Sealing caps are provided on the oil inlet 620 and the oil outlet 630. The sealing caps are threadedly connected to the oil inlet 620 and the oil outlet 630.

[0069] Now combined Figure 1 Details of the pumping and drainage mechanism 200 are explained.

[0070] like Figure 1As shown, the pumping and drainage mechanism 200 includes a water pipe and a water pump. The water pipe connects the water-containing cavity 110 to the outside, and the water pump is installed on the hull 100. The water pump can inject water from the outside into the water-containing cavity 110, and / or, the water pump can drain water from the water-containing cavity 110 to the outside.

[0071] In one embodiment, the drainage mechanism 200 consists of two sets. One set of the drainage mechanism 200 uses a pump to draw water from the outside and inject it into the water-receiving chamber 110. The other set of the drainage mechanism 200 uses a pump to draw water from the water-receiving chamber 110 and discharge it to the outside. The two sets of pumps can simultaneously adjust the water volume in the water-receiving chamber 110, which improves the flexibility of adjusting the water volume in the water-receiving chamber 110.

[0072] Specifically, the water pipes include inlet pipes and outlet pipes. The inlet pipe is used for pumping water, and the outlet pipe is used for draining water. Each of the two sets of pumping and draining mechanisms 200 has two inlet pipes and two outlet pipes. One set of pumping and draining mechanisms 200 is used to inject seawater into the water-containing chamber 110. One end of the inlet pipe of this mechanism is connected to the seawater, and the other end is connected to a water pump. One end of the outlet pipe of this mechanism is connected to the water-containing chamber 110, and the other end is connected to a water pump. The other set of pumping and draining mechanisms 200 is used to discharge seawater from the water-containing chamber 110 to the outside. One end of the inlet pipe of this mechanism is connected to the bottom of the water-containing chamber 110 so that the inlet pipe can draw seawater from the water-containing chamber 110, and the other end is connected to a water pump. One end of the outlet pipe of this mechanism is connected to the outside, and the other end is connected to a water pump.

[0073] Of course, the water pumps of the two sets of pumping and draining mechanisms 200 can simultaneously inject seawater into the water storage chamber 110 or pump seawater out of the water storage chamber 110 to improve the regulation efficiency.

[0074] In another embodiment, the pumping mechanism 200 can be a set, whereby the pump can draw water from the outside and inject it into the water-receiving chamber 110, or the pump can draw water from the water-receiving chamber 110 and discharge it to the outside, thereby adjusting the water volume in the water-receiving chamber 110. Exemplarily, the pump can be a structure with bidirectional pumping function.

[0075] Furthermore, within the plane jointly defined by the first direction Y and the second direction Z, the cross-sectional shape of the water-containing cavity 110 is the same as that of the hull 100, which is beneficial to increasing the volume of the water-containing cavity 110, thereby increasing the seawater capacity in the water-containing cavity 110.

[0076] Specifically, the hull 100 includes an outer wall 120 and an inner wall 130, which are spaced apart to form a water-containing cavity 110.

[0077] When the wind and waves are large, while the balancing mechanism 300 is working, the water pump can be started to draw seawater and inject it into the water-containing chamber 110 to increase the weight of the oil loading and unloading device, increase the draft, and lower the center of gravity of the hull 100, thereby increasing the stability of the oil loading and unloading device against wind and waves.

[0078] When it is necessary to reduce load or change the work area, the pump of the drainage mechanism 200 is reversed to drain the seawater in the water chamber 110, and the draft and buoyancy balance of the hull 100 are flexibly adjusted.

[0079] Now combined Figures 1-4 Details of the balancing mechanism 300 are explained.

[0080] like Figures 1-4 As shown, the balancing mechanism 300 includes a drive assembly 310 and an adjusting plate 320. The drive assembly 310 is disposed on one side of the hull 100, and the adjusting plate 320 is connected to the drive assembly 310. The drive assembly 310 is configured to drive the adjusting plate 320 to reciprocate along a second direction Z and to drive the adjusting plate 320 to swing around a third direction X. The second direction Z is perpendicular to the first direction Y, and the third direction X is perpendicular to both the first direction Y and the second direction Z. The balancing mechanism 300 adjusts the position of the adjusting plate 320 relative to the hull 100 according to the angle of the hull 100 via the drive assembly 310, so that the position of the adjusting plate 320 adapts to the direction of wind and waves. The adjusting plate 320 is in different positions relative to the hull 100, so that the adjusting plate 320 adjusts the buoyancy distribution on both sides of the hull 100 to counteract the heeling moment of the hull 100, thereby actively restoring horizontal balance.

[0081] Meanwhile, when the wind and waves are large, while the balancing mechanism 300 is working, the water pump can be started to draw seawater and inject it into the water-containing chamber 110 to increase the weight of the oil loading and unloading device, increase the draft, and lower the center of gravity of the hull 100, thereby increasing the stability of the oil loading and unloading device against wind and waves.

[0082] When it is necessary to reduce load or change the work area, the pump of the drainage mechanism 200 is reversed to drain the seawater in the water chamber 110, and the draft and buoyancy balance of the hull 100 are flexibly adjusted.

[0083] The adjusting plate 320 includes a connecting part 321 and a working part 322. The connecting part 321 is connected to the drive assembly 310, and the working part 322 is connected to the connecting part 321. The working part 322 adjusts the buoyancy by adjusting its angle and position relative to the seawater to adapt to the angle of wind and waves. For example, both the connecting part 321 and the working part 322 are plate-shaped structures.

[0084] Further, the drive assembly 310 includes a first guide member 311, a drive member 312, a connecting screw 313, and a first slider 314. The first guide member 311 is disposed on one side of the hull 100 and has a first guide groove 3111 extending along the second direction Z. The drive member 312 is disposed on the first guide member 311. The connecting screw 313 is disposed in the first guide member 311 along the second direction Z. The output end of the drive member 312 is connected to the connecting screw 313. The first slider 314 is slidably disposed in the first guide groove 3111. The first slider 314 is sleeved on the connecting screw 313 and threadedly connected to the connecting screw 313. The adjusting plate 320 is connected to the first slider 314. The drive member 312 is configured to drive the connecting screw 313 to rotate, causing the first slider 314 to reciprocate along the second direction Z in the first guide groove 3111, thereby driving the adjusting plate 320 to move along the second direction Z. The drive assembly 310 can drive the adjustment plate 320 to reciprocate along the second direction Z.

[0085] For example, the first guide member 311 may be a frame structure, the upper end of which is used to fix the drive member 312. The drive member 312 is a servo motor. The high precision of the servo motor is beneficial for the drive assembly 310 to accurately control the position and angle of the adjustment plate 320 according to the condition of the hull 100.

[0086] The drive assembly 310 also includes a second guide member 315, a second slider 316, and a guide rod 317. The second guide member 315 is provided with a second guide groove 3151 extending along the second direction Z. The second guide member 315 and the first guide member 311 are parallel to each other along the third direction X and are spaced apart on one side of the hull 100. The second slider 316 is slidably disposed in the second guide groove 3151 and is connected to the adjusting plate 320. The first slider 314 and the first slider 315 together support the adjusting plate 320. The guide rod 317 is disposed in the second guide groove 3151 along the second direction Z and passes through the second slider 316.

[0087] The second slider 316 and the first slider 314 together support the adjusting plate 320, which helps to maintain the stability of the adjusting plate 320 extending in the first direction Y, thereby improving the accuracy of adjusting the hull angle 100.

[0088] The drive assembly 310 also includes a gear 318 and a rack 319. The gear 318 is rotatably connected to either the first slider 314 or the second slider 316, and is fixedly connected to the adjusting plate 320. The rack 319 extends along the second direction Z and is mounted on the hull 100. The gear 318 meshes with the rack 319. When the drive member 312 drives the first slider 314 to move along the second direction Z, it can drive the gear 318 to rotate relative to the rack 319, thereby causing the adjusting plate 320 to swing. Thus, while the drive member 312 drives the adjusting plate 320 to move along the second direction Z, it can also drive the adjusting plate 320 to swing. This drive assembly 310, through the gear 318 and rack 319 structure, can precisely adjust the angle of the adjusting plate 320 to adjust the buoyancy distribution on both sides of the hull 100, counteracting the heeling moment of the hull 100, and thus actively restoring horizontal balance. This device can adapt to different wind and wave intensities.

[0089] The drive assembly 310 moves vertically via the adjusting plate 320, and is simultaneously forced to rotate under the action of the gear 318 and rack 319, achieving real-time linkage between the displacement and angle of the adjusting plate 320. Combined with the constraints of the first guide groove 3111 and connecting screw 313, and the second guide groove 3151 and guide rod 317, it prevents jamming during the adjustment process of the adjusting plate 320, thus solving the problems of the adjusting plate 320 having a fixed angle and only being able to passively bear force in the transmission device. In this embodiment, the oil loading and unloading device can accurately adapt to various sea conditions such as transverse waves and oblique waves.

[0090] Furthermore, in order to precisely control the angle of the adjustment plates 320 located on the left and right sides of the hull 100, the balancing mechanism 300 also includes a sway sensor 330, which is electrically connected to the two drive components 310 of the two balancing mechanisms 300. In this way, the drive component 310 on one side of the hull 100 can be driven to work or the two drive components 310 on both sides of the hull 100 can work simultaneously, based on the sensing result of the sway sensor 330.

[0091] like Figure 5 As shown, the hull 100 is provided with an oil storage chamber 140, and the oil loading and unloading device further includes at least one first partition 400 and at least one second partition 500. The first partition 400 extends along a third direction X and is disposed in the oil storage chamber 140, and is configured to divide the oil storage chamber 140 into at least two sub-chambers 141 in a third direction Y. The second partition 500 extends along the first direction Y and is disposed in the oil storage chamber 140, and is configured to divide the oil storage chamber 140 into at least two sub-chambers 141 in a third direction X. The first partition 400 and the second partition 500 divide the oil storage chamber 140 into multiple sub-chambers 141.

[0092] In another embodiment, the oil loading and unloading device further includes at least one first baffle 400 extending in a third direction X within the oil storage chamber 140, configured to divide the oil storage chamber 140 into at least two sub-chambers 141 in a first direction Y. Alternatively, the oil loading and unloading device further includes at least one second baffle 500 extending in a first direction Y within the oil storage chamber 140, configured to divide the oil storage chamber 140 into at least two sub-chambers 141 in a third direction X. This oil loading and unloading device facilitates the oscillation of oil within the sub-chambers 141 when the hull 100 is rocking in wind and waves, reducing the impact of the oil's inertial motion on the overall motion of the hull 100.

[0093] The first partition 400 and the second partition 500 are arranged in a crisscross pattern, thereby dividing the oil storage chamber 140 into multiple sub-chambers 141.

[0094] The first partition 400 is provided with a first through hole 410, which is located near the bottom of the hull 100; or the second partition 500 is provided with a second through hole 510, which is located near the bottom of the hull 100 along the second direction Z.

[0095] The oil storage chamber 140 is structured with a wide top and narrow bottom, and a deeper oil level in the middle, through the first partition 400, the second partition 500, the first through hole 410 and the second through hole 510. When the hull 100 is rocked by wind and waves, the oil automatically converges into the sub-chamber 141 in the middle through the first through hole 410 and the second through hole 510 by gravity. By utilizing the principle of "mass concentrated at the center of the hull 100", the swaying amplitude of the hull 100 is reduced, and the self-stabilizing effect principle similar to "liquid damper" is used to suppress the rocking.

[0096] The oil loading and unloading device utilizes a combination of a pumping and draining mechanism 200, a balancing mechanism 300, a first baffle 400, a second baffle 500, a first through hole 410, and a second through hole 510 to improve the stability of the oil loading and unloading device under complex sea conditions.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
