Description

Technical Field

[0001] The present invention belongs to the technical field of ship design and manufacturing, and particularly relates to a steam filling port for ships applicable to polar waters. Background Art

[0002] In recent years, the ice cover area in polar waters has significantly decreased, and correspondingly, the volume of freight and energy transportation has increased significantly in recent years. However, the polar environment is relatively harsh and very fragile. If a ship sinks in the polar region, not only is it difficult to carry out rescue and salvage work, but the remaining oil in the sunken ship will pose a major hidden danger to the polar environment.

[0003] If the remaining oil in the sunken ship cannot be pumped out in time in the polar region, then with the corrosion of seawater, the remaining oil is extremely likely to leak. However, due to the obstruction of floating ice, the leaked oil adheres to the bottom of the floating ice and is difficult to recover, causing great damage to the fragile marine ecosystem in the polar region. Compared with the recovery of remaining oil in open areas, carrying out such work in the polar region will be hindered by floating ice and low temperature, with high danger. In addition, the low temperature environment will increase the viscosity of the remaining oil, which is not conducive to pumping out the remaining oil.

[0004] Currently, the common method for dealing with the remaining oil in a sunken ship is to send divers or underwater robots to locate and drill holes at designated locations on the sunken ship, insert an oil extraction pipe, or insert a steam injection pipe when necessary. However, for the polar region with a lot of ice and extremely cold environment, this operation method is cumbersome and complex, with high uncertainty and great risk. It is very easy to occur situations such as divers suffering from hypothermia or equipment being damaged by floating ice. Currently, there is no special emergency disposal system for the remaining oil in sunken ships in polar waters.

[0005] Compared with using complex polar oil extraction equipment and technological processes, if the ship itself reserves emergency oil extraction disposal equipment, it will greatly reduce the difficulty of emergency disposal of the remaining oil in sunken ships in the polar region. However, due to the uncertain attitude of the sunken ship, it is necessary to scientifically distribute steam filling ports on the ship so that there is a steam filling port for steam injection in any attitude of the sunken ship. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems and provide a steam filling port for ships applicable to polar waters. Through multiple sets of steam filling units provided, no matter in what attitude the hull sinks in polar or cold region seas, there is always a steam injection port exposed outside, so that steam can be injected to heat the fuel tank, solving the problem that the viscosity of the remaining oil in the fuel tank increases and it is difficult to extract.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A steam filling port for ships applicable to polar waters, including a hull provided with a fuel tank, the hull having a ship wall, and the ship wall being provided with steam filling units. Each steam filling unit includes a plurality of steam filling ports, and the steam filling ports are communicated with the fuel tank to heat the fuel in the fuel tank.

[0008] According to the present invention, further, the steam injection ports that make up the steam injection unit are respectively arranged at the highest point of the midship of the hull, the highest point of the side, the middle position of the bilge, and the middle position of the bottom opposite to the midship.

[0009] According to the present invention, further, steam injection ports are arranged on both sides of the hull.

[0010] According to the present invention, further, steam injection ports are arranged at the bilges on both sides of the hull.

[0011] According to the present invention, further, two sets of the steam injection unit are arranged along the ship length direction.

[0012] According to the present invention, further, more than two sets of the steam injection unit are arranged along the ship length.

[0013] According to the present invention, further, the two sets of the steam injection unit are respectively arranged at different frame positions, that is: Frame A at the middle of the fuel tank and Frame B at the maximum distance Lmax from the fuel tank in the ship length direction. Lmax can ensure that the injected steam still has a heating effect on the fuel tank when it reaches the fuel tank.

[0014] According to the present invention, further, two of the steam injection units are respectively arranged at different frame positions, that is: Frame A at the middle of the fuel tank and Frame B at the maximum distance Lmax from the fuel tank in the ship length direction, and the other steam injection units can be arranged between Frame A and Frame B as required.

[0015] According to the present invention, further, a steam injection port is arranged at the middle line of the uppermost end of the ship bow of the hull.

[0016] According to the present invention, further, a steam injection port is arranged at the uppermost end of the ship stern of the hull.

[0017] Compared with the prior art, the beneficial effect of the present invention is that multiple steam injection units can ensure that no matter what the grounding posture is after the ship sinks and whether it is covered by seabed silt or other objects, there is always at least one injection port that can be found so that steam can be injected, improving the success rate of extracting fuel.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 shown, a steam filling port for a ship applicable to polar waters in an embodiment of the present invention includes a hull 1, a fuel tank 2 is arranged inside the hull 1, a plurality of steam filling units are opened on the ship wall of the hull 1, each steam filling unit includes a plurality of steam filling ports 3, and the steam filling ports 3 are communicated with the fuel tank 2 through pipelines to realize heating of the fuel in the fuel tank 2 and reduce the fuel viscosity.

[0028] Specifically, as Figure 2 shown, the steam filling ports 3 that make up the steam filling unit are respectively arranged at the highest point of hogging 31, the highest point of side 32, the middle position of bilge 33 and the middle position of bottom 34 opposite to the hogging of the hull 1. Preferably, steam filling ports 3 are arranged on both sides of the side and bilge.

[0029] In this embodiment, as Figure 1As shown, there are two sets of steam injection units, both arranged along the ship length direction; preferably, the two sets of steam injection units are respectively arranged at frame positions, that is: Frame A at the middle of the fuel tank and Frame B at the maximum distance Lmax from the fuel tank 2 in the ship length direction. Arranging at Frame B can ensure that the steam will not condensate after being transported from the steam injection port 3 to the fuel tank 2. Here it is noted that if the fuel tank 2 is located at the position near the ship stern, then Frame B is located at the position near the ship bow; if the fuel tank 2 is located at the position near the ship bow, then Frame B is located at the position near the ship stern; if the fuel tank is located at the midship position, then Frame B can be arranged at the position near the ship bow or stern according to actual needs, or can be arranged at both the ship bow and stern simultaneously. Preferably, Frame B is located on the parallel middle body. One or more additional sets of steam injection units can also be added between Frame A and Frame B. Arranging two or more steam injection units in the ship length direction is considered because if the whole ship stern or bow is buried, in this case, steam can be injected from one of the steam injection ports 3 of the unburied steam injection unit, which can achieve the effect of improving the success rate of steam injection.

[0030] In this embodiment, considering the most extreme situation, there are also corresponding arrangements of the steam injection ports at the top middle line 35 of the ship bow and the top 36 of the ship stern, ensuring that steam injection can be carried out even in the most extreme attitude of the sunken ship. And arranging a steam injection port 3 at the midship of the top of the ship bow and the top of the ship stern respectively is considered because in the most extreme sunken ship attitude, there will always be a steam injection port 3 that can be discovered externally and corresponding steam injection can be carried out.

[0031] This setting of the injection port 3 can ensure that no matter what the sitting posture of the sunken ship is, whether it is covered by seabed silt or other items, there will always be at least one steam injection port 3 that can be found, so that steam can be injected to steam-heat the remaining oil in the fuel tank 2.

[0032] Then considering the extreme situation where the sunken ship lies on the flat seabed, the central axis in the ship length direction is parallel to the seabed, and most of the hull is buried but a small part is exposed outside the sediment, this arrangement can meet the requirement that there will always be a steam injection port 3 exposed under this extreme condition for injecting steam.

[0033] As Figure 3A shown, if only the uppermost main deck of the hull is exposed and the main deck plane is parallel to the seabed, then it can be ensured that the steam injection port 3 at the highest point of the hogging 31 is exposed outside the seabed sediment;

[0034] As Figure 3B shown, if only the junction of the side and the main deck of the hull is exposed, then it can be ensured that the steam injection port 3 at the highest point of at least one side 32 is exposed outside the seabed sediment;

[0035] As Figure 3CAs shown, if only the side of the hull is exposed and the side plate is parallel to the seabed, then it can also ensure that the steam filling port 3 at the highest point 32 of at least one side is exposed outside the seabed sediment;

[0036] As Figure 3D shown, if only the bilge of the hull is exposed, then it can ensure that the steam filling port 3 at the middle position 33 of at least one side of the bilge is exposed outside the sediment;

[0037] As Figure 3E shown, if the bottom of the hull is exposed, then it can ensure that the steam filling port 3 at the middle position 34 of the bottom opposite to the hogging is exposed outside the sediment.

[0038] As long as the steam filling device can reach an undamaged filling port, it can complete the steam filling and then heat the remaining oil in the oil tank in the extremely cold area to reduce its viscosity.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
