Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to an anti-sinking device for an ocean platform. Background Art

[0002] Mobile offshore oil platforms cannot propel themselves, requiring towage for each relocation. Due to the influence of wind and waves, towing can lead to collisions with obstacles and ships in the tow route, resulting in safety accidents such as cabin damage. Furthermore, due to poor construction quality, particularly welding quality, cabins can also be towed after a period of towing, even though the platform is initially free of water and then floods in the sea.

[0003] Currently, the primary approach to preventing damage to offshore platforms is during the design phase. Damage stability is calculated according to regulations, requiring that a single compartment remain intact and that residual stability meet requirements. While meeting operational requirements, large compartments are avoided whenever possible. Other approaches include adding non-watertight bulkheads and double-bottom tanks to dangerously located wing tanks.

[0004] After the platform is built, the stability of the damaged cabin can no longer be prevented from the design aspect, and emergency measures are required. Usually, the platform will tilt to a certain extent after the cabin is damaged in the sea. This tilting process is not instantaneous, and there is generally a process in which the tilt angle gradually increases. The platform and the personnel on it need to wait for rescue after the cabin is damaged, which requires buying time. The current emergency measures generally adopted are to drain the damaged cabin and repair the leak. Due to the high external water pressure after the damage, drainage is more difficult, and since the submerged part cannot be welded, the leak can only be repaired by splicing, which is not very effective.

[0005] In view of this, how to provide an offshore platform anti-sinking device that can improve the tilted floating state of the offshore platform has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of the embodiments of the present invention is to provide an anti-sinking device for an offshore platform, which can reduce the platform's tilt angle and improve the platform's tilt state during use, so as to better protect the platform and improve safety.

[0007] In order to solve the above technical problems, an embodiment of the present invention provides an anti-sinking device for an offshore platform, comprising: a transmission device for being installed on the platform body and an inflatable float detachably installed on the transmission device, wherein the transmission device is used to transmit the inflatable float to the water after startup, so that the inflatable float enters the water.

[0008] In one embodiment, the transmission device includes a transmission base, a belt motor, a transmission belt, a belt transmission shaft, and a belt track, wherein the transmission base is used to be installed on the platform body, the belt motor and the belt transmission shaft are both provided on the transmission base, the belt track is connected to the belt motor via the belt transmission shaft, and the inflatable buoyancy box is used on the detachable transmission belt;

[0009] The belt motor is used to drive the transmission belt along the belt track through the belt transmission shaft after starting;

[0010] The transmission belt is used to transmit the inflatable buoyancy box into the water during the transmission process.

[0011] In one embodiment, the transmission device further includes a first pontoon belt fixing buckle, and the inflatable pontoon is mounted on the transmission belt via the first pontoon belt fixing buckle.

[0012] In one embodiment, the belt track includes multiple sections of sub-belt tracks and multiple belt track connectors, and each two adjacent sections of the sub-belt tracks are connected by the belt track connectors.

[0013] In one embodiment, there are multiple inflatable pontoons, and the transmission device further includes a pontoon connecting rod, and two adjacent inflatable pontoons are connected by the pontoon connecting rod.

[0014] In one embodiment, the transmission base is bound to the railing on the platform body by tying steel wire ropes.

[0015] In one embodiment, it also includes: a support base for installation on the platform body, a power device arranged on the support base, a support rod connected to the power device, and a support shoe connected to the bottom end of the support rod, wherein the power device is used to push the support rod to drive the support shoe to extend to the bottom of the water and support the platform body.

[0016] In one embodiment, the power equipment includes an electro-hydraulic jack and a jack push rod, wherein:

[0017] The electric hydraulic jack is used to push the support rod to slide downward through the jack push rod.

[0018] In one embodiment, the support rod includes multiple sub-support rods and multiple support rod connectors, and two adjacent sub-support rods are detachably connected via the support rod connectors.

[0019] In one embodiment, a support rod bracket is further included for supporting the support rod so that the support rod slides downward along the support rod bracket.

It can be seen that the transmission device in the present invention can be installed at a position on the platform body corresponding to the position where the damaged compartment is flooded, and then the inflatable pontoon is detachably installed on the transmission device, and the transmission device is activated so that the transmission device transfers the inflatable pontoon into the water. Since the inflatable pontoon is subject to the buoyancy of the water in the water, the buoyancy can generate a lifting buoyancy on the inclined position of the platform, thereby reducing the inclination angle of the platform, improving the inclination state of the platform, and better protecting the platform and improving safety.

[0025] An embodiment of the present invention provides an anti-sinking device for an offshore platform, which can reduce the platform's tilt angle and improve the platform's tilt state during use, thereby better protecting the platform and improving safety.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Currently, when an offshore platform experiences a tank damage and tilting incident, the primary approach is to drain the damaged compartment. Because it's uncertain whether water ingress will cause the platform to sink, safety measures are typically taken to evacuate personnel to lifeboats or life rafts. Contact is then made with land, and the rescue vessel awaits arrival. If the incident is close to shore, rescue is relatively quick; if it's offshore, assistance may take a long time. However, the damage to the platform can be severe, leading to rapid tilting. Even the fastest rescue vessel may be unable to reach the platform in time. Strong winds and rough seas, combined with inclement weather, can make it difficult for a rescue vessel to reach the platform.

[0028] The current treatment method is generally to drain the damaged compartment. As the platform tilts more and more, water will continue to enter the damaged compartment. If the shape of the damaged opening is not conducive to drainage, drainage will become very difficult. Since it is not at the shipyard slipway, the leak-proof welding of the damaged opening can only be partially carried out.

[0029] The above analysis demonstrates that current drainage and leak repair technology can only delay the platform's tilt after a breach, but cannot fundamentally improve its tilting and buoyancy. Furthermore, in adverse weather conditions or when rescue efforts are slow, it is unavoidable that the platform will continue to tilt or even sink. Ultimately, the result is likely to be a significant threat to the safety of the platform and its equipment, even though personnel may be rescued.

[0030] Based on this, the embodiment of the present invention provides an anti-sinking device for an offshore platform. Figure 1 , Figure 1 A schematic diagram of the structure of an anti-sinking device for an offshore platform main body provided by an embodiment of the present invention. The anti-sinking device for an offshore platform main body comprises: a transmission device 1 for installation on the platform main body; and an inflatable pontoon 2 detachably mounted on the transmission device. The transmission device 1 is configured to transfer the inflatable pontoon 2 into the water after activation, so that the inflatable pontoon 2 enters the water.

[0031] It should be noted that, in actual application, after a tank is damaged and water is ingested during towing, the anti-sinking device provided in the embodiment of the present invention can be immediately installed on the platform body at the location of the tank damage. Specifically, the transmission device 1 can be installed and fixed on the platform body (e.g., the deck), and then the inflatable pontoon 2 can be inflated by an air pump, and the inflated pontoon 2 can be installed on the transmission device 1. The transmission device 1 in this application can enter the water and drive the inflatable pontoon 2 into the water. Since the inflatable pontoon 2 will be subject to the buoyancy of the water after entering the water, the buoyancy of the inflatable pontoon can be used to force the buoyancy of the tilted position to stop or even reverse the slow tilting process of the platform, thereby improving the overturning state of the platform. The inflatable pontoon 2 in the embodiment of the present invention is an inflatable pontoon. The transmission device 1 can be detachably installed on the platform body, and the inflatable pontoon 2 can also be detachably installed on the transmission device 1, so that the device is easy to use and easy to store after use, saving space.

[0032] In one embodiment, see Figure 2 The transmission device 1 includes a transmission base 11, a belt motor 12, a transmission belt 13, a belt transmission shaft 14 and a belt track 15, wherein the transmission base 11 is used to be installed on the platform body, the belt motor 12 and the belt transmission shaft 14 are both arranged on the transmission base 11, the belt track 15 is connected to the belt motor 12 through the belt transmission shaft 14, and the inflatable buoyancy box 2 is used on the detachable transmission belt 11;

[0033] The belt motor 12 is used to drive the transmission belt 13 along the belt track 15 through the belt transmission shaft 14 after starting;

[0034] The transmission belt 13 is used to transmit the inflatable buoyancy box 2 into the water during the transmission process.

[0035] It should be noted that the transmission device 1 in the embodiment of the present invention may include a transmission base 11, a belt motor 12, a transmission belt 13, a belt transmission shaft 14 and a belt track 15. In actual application, the transmission base 11 can be fixed on the platform body, specifically, it can be fixed on the platform body by welding or other means. The embodiment of the present invention does not make special restrictions on this, and the belt motor 12 is installed on the transmission base 11, wherein the belt motor 12, the belt transmission shaft 14, the belt track 15 and the transmission belt 13, and the inflated inflatable pontoon 2 is installed on the transmission belt 13 , wherein the belt motor 12 can use the power provided by the marine platform to power on, drive the transmission belt 13 to transmit along the belt track 15, and transport the inflatable buoyancy box 2 into the water during the transmission process, so that the inflatable buoyancy box enters the water. Since the inflatable buoyancy box 2 in this application is fixed on the transmission belt 13 on the belt track 15, when the water generates buoyancy on the inflatable buoyancy box 2, the entire belt track will be subject to buoyancy. Since the transmission base 11 is fixed on the platform body, the buoyancy can act on the damaged cabin of the platform, thereby reducing the tilt and realizing the adjustment and improvement of the damaged cabin tilt.

[0036] It should also be noted that, in actual use, the transmission base 11 can also be tied to the railing B on the platform body by tying steel wire ropes A, and the belt track 15 can be tied to the railing B, thereby increasing the security of the transmission base 11 and the belt track 15. In addition, in actual use, a walking ladder C can be provided in conjunction with the transmission base 11 so that workers can access the transmission base 11 via the walking ladder C and secure the inflatable pontoon 2 to the transmission belt 13.

[0037] Furthermore, the transmission device 1 in the embodiment of the present invention further includes a pontoon belt fixing buckle 16 , and the inflatable pontoon 2 is mounted on the transmission belt 13 via the pontoon belt fixing buckle 16 .

[0038] It is understandable that in actual application, the inflatable pontoon 2 can be fixed to the transmission belt 13 through the pontoon belt fixing buckle, which not only can achieve fixation, but also can be easily disassembled after use, which is conducive to overall storage.

[0039] Furthermore, the belt track 15 in the embodiment of the present invention includes a plurality of sub-belt tracks and a plurality of belt track connectors, and every two adjacent sub-belt tracks are connected by a belt track connector.

[0040] Specifically, in order to facilitate installation and to make the length of the belt track 15 meet the requirements, multiple sections of the belt track can be connected to each other through the belt track connector to make the length of the formed belt track 15 meet the requirements. Among them, the detachable connection between each two adjacent sections of the belt track through the belt track connector can facilitate the subsequent storage of the device and save space.

[0041] Furthermore, in the embodiment of the present invention, there are multiple inflatable pontoons 2 , and the transmission device 1 further includes a pontoon connecting rod 17 , and two adjacent inflatable pontoons 2 are connected by the pontoon connecting rod 17 .

[0042] It is understood that to increase buoyancy and enhance the ability to adjust the platform's tilt due to damage, multiple inflatable pontoons 2 can be installed on the transmission belt, with adjacent pontoons 2 connected by pontoon connecting rods 17. Specifically, the pontoons 2 can be fixed one by one to the belt track 15. Specifically, two to three pontoons 2 can be fixed at a time, and the belt motor 12 can be activated to move the belt, transporting the pontoons 2 into the water. After the previous group of pontoons 2 enters the water, the next group of pontoons 2 is connected, with pontoon connecting rods 17 connecting each pontoon 2. As more pontoons 2 enter the water, the buoyancy generated by the pontoons 2 creates a lifting force on the platform's tilt, reducing the platform's tilt and stopping further tilt, thereby better protecting the platform. Of course, in actual applications, all pontoons 2 can also be fixed to the transmission belt 13, and then the belt motor 12 can be activated to drive the pontoons 2 into the water. The specific implementation method is not particularly limited in the embodiments of the present invention.

[0043] In one embodiment, please refer to Figure 3 The anti-sinking device may also include: a support base 3 for installation on the platform body, a power device 4 arranged on the support base 3, a support rod 5 connected to the power device 4, and a support shoe 6 connected to the bottom end of the support rod 5. The power device 4 is used to push the support rod 5 to drive the support shoe 6 to extend to the bottom of the water and support the platform body.

[0044] It should be noted that in order to further ensure the safety of the marine platform, a support base 3 can also be provided in the embodiment of the present invention. The support base 3 can be installed on the platform body (such as the deck) at the damaged position, and then the power equipment 4 can be installed on the support base 3, and the support rod 5 connected to the power equipment 4 and the support boot 6 connected to the support rod 5 can be installed. The support rod 5 of a certain length with the support boot 6 installed at one end can be inserted into the water in advance until the support boot 5 reaches the bottom of the water, and then the power equipment 4 is started, and the support rod 5 is pushed by the power equipment 4, so that the support rod 5 and the support boot 6 generate pressure on the bottom of the water. The support of the support boot 6 on the bottom of the water can form a supporting force relative to the damage of the platform, thereby further improving the degree of inclination at the damaged position, and slowly restoring the inclination to further ensure the safety of the platform.

[0045] Among them, in order to facilitate installation and storage and maintenance, the support rod 5 in the embodiment of the present invention includes multiple sub-support rods 51 and multiple support rod connectors 52, and two adjacent sub-support rods 51 are detachably connected through the support rod connectors 52.

[0046] In one embodiment, the power device 4 includes an electric hydraulic jack 41 and a jack push rod 42, wherein:

[0047] The electric hydraulic jack 41 is used to push the support rod 5 to slide downward through the jack push rod 42.

[0048] It is understandable that, based on this, a certain number of sub-support rods 51 can be selected and connected through support rod connectors 52 to obtain a support rod 5 of appropriate length and to install support boots 6. The support rod 5 is then lowered into the water until the support boots 6 reach the bottom. Then, the electric hydraulic jack 41 is energized. After the electric hydraulic jack 41 is activated, the electric hydraulic jack 41 pushes the support rod 5 through the jack push rod 42. Since the support boots 6 have already reached the bottom of the water, the hydraulic pressure causes the support rod 5 and support boots 6 to increasingly increase their support force on the platform, thereby further generating a correction effect on the continuous tilt of the platform and reducing the platform's swaying in wind and waves.

[0049] In addition, the device may further include a support rod bracket 7 for supporting the support rod 5 so that the support rod 5 slides downward along the support rod bracket 7 .

[0050] That is, in order to further improve the stability of the device in the embodiment of the present invention, a support rod bracket 7 can be additionally provided, and the support rod bracket 7 can be fixedly connected to the railing of the platform, thereby increasing the stability.

[0051] It should also be noted that the anti-sinking device provided in this application can control the accident of cabin damage and tilting. Since the components of the anti-sinking device in this application can be disassembled and stored, after the rescue work is completed, the base, connecting rods, support rods, belts, cables, etc. of the device can be removed, the binding wire ropes can be loosened, and the motors, jacks and other equipment can be checked for problems. Then, the devices can be classified and stored at designated locations for future use.

[0052] It can be seen that the transmission equipment in the present invention can be installed at a position on the platform body corresponding to the position where the water enters the damaged cabin, and then the inflatable float can be detachably installed on the transmission equipment. The transmission equipment is started to enable the transmission equipment to transfer the inflatable float into the water. Since the inflatable float will be affected by the buoyancy of the water in the water, the buoyancy can generate a lifting buoyancy on the inclined position of the platform, thereby reducing the inclination angle of the platform, improving the inclination state of the platform, and better protecting the platform and improving safety.
