Apparatus and method for recovering liquid from a submerged container
Field of the invention
The present invention relates to an apparatus for recovering liquid 5 from a submerged container, and more particularly to an apparatus according to the preamble of the attached independent apparatus claim. Such apparatus can typically be used for recovering liquid, such as oil, from a container of a sunken ship in order to reduce environment damage due to liquid leaking out from the container to the surrounding sea.
10 The present invention relates also to a method for recovering liquid from a submerged container, and more particularly to a method according to the preamble of the attached independent method claim.
Background of the invention
Such an apparatus and method for recovering liquid in known from 15 U S. Patent No. 7 377 226 B2. A drawback of this known apparatus is that it is in practice difficult to attach to the submerged container. This is owing to the fact that the fixing arrangement for fixing the valve arrangement of the apparatus to the site of the hole of the submerged container comprises a plurality of special designed DTB members comprising a drilling part at the tip of the DTB 20 member followed by a screw tap part, a bolt and a bolt head at the upper end of the DTB member, said parts of the DTB members being integrally formed with each other. Fastening these DTB members to the submerged container is difficult, because the DTB members easily break during the fastening work. They have a tendency to break, because they have in practice to be small and ^ 25 hard in order to penetrate the wall of the container and perform the required o ^ tasks of drilling, tapping and also functioning as bolts. Such small and hard o members are easily overloaded during mounting and fastening thereof, wherein upon they easily break. If they break during mounting, one has to find a new g place from the submerged container for fixing the valve arrangement and one Ω.
30 must make new drilling position markings on the submerged container. This $ new mounting place of the submerged container must - like the previous
LO
mounting place - be cleaned before the valve arrangement can be fixed to the ° container. This is time cumbersome and consuming. Further, in order for the DTB members to perform drilling, tapping and bolting, they need to be rather 35 long (about 100mm), which, in turn, means that there must be a corresponding 2 empty space (of circa 100 mm) inside the submerged container behind the inner wall thereof. Such empty space is not always available, which complicates to find an adequate mounting site for the apparatus and hence makes the mounting even more difficult. As the valve arrangement of this known appa-5 ratus is fastened with a plurality of DTB-members which are positioned circumferentially outside the valve arrangement, the valve arrangement requires a large mounting surface.

15 Detailed description of the invention
Figure 1 shows a submerged container 5 to which is attached an apparatus 1 of the invention for recovering liquid, e.g. oil, from the container 5. The apparatus 1 is connected by a hose 27 to remote control means 28 of a ship 29. On board the ship 29 is power supply 31 for driving essential functions 20 of the apparatus 1. Typically the power supply 31 delivers through hose 27 electricity to the apparatus 1. Hydraulic power and/or pneumatic power may also be included in the power supply 31.
The apparatus 1 for recovering liquid is shown in more detail in figures 2 to 4.
25 The apparatus 1 comprises a frame 20 to support different compo- nents of the apparatus.
o In order to prevent water from entering to such components that c\i ^ may become damaged owing to water, the apparatus comprises a protective ® encapsulation 24. This encapsulation 24 also prevents liquid from escaping Γ"» ^ 30 from the container 5 to the water outside the container 5 after a through hole 8 £ has been processed to the container 5 with the apparatus 1, c.f. 5 to 8 and 10 where such a hole 8 (8’ in Figure 10) is seen.
CO
The apparatus 1 is attached to the outer surface of the submerged £ container 5 with a plurality of chucking devices 2a, 2b. In the embodiment 00 35 shown, there are nine chucking devices 2a, 2b. The number may, however, vary. Typically at least three chucking devices are needed in order to provide 4 good attachment of the apparatus to the container 5. The chucking devices 2a, 2b comprise suction pads (indicated with reference numeral 2a) and magnetic devices (indicated with reference numeral 2b), e.g. electromagnetic devices to be activated with electricity. It is conceivable that either magnetic devices or 5 suction pads are missing so that the cucking devices comprise e.g. only suction pads, or alternatively only magnetic devices.
The apparatus comprises a working area 21 or working space, best seen in Figure 3, for accommodating a tool 3a for processing aforementioned hole 8 to the submerged container 5. The processing tool 3a can be moved 10 two-dimensionally in a X-Y -plane along the outer surface of the submerged container 5 in order to enable processing of a hole having arbitrary geometrical form, and especially forms deviating from a circle, e.g. a hole 8 having a geometrical form shown in Figure 6 or a hole 8’ having a geometrical form shown in Figure 10. In order to move the processing tool 3a two-dimensionally in the 15 working area 21, the tool 3a is part of a tool assembly 3 which comprises transfer means 9 generally indicated by reference sign 9, for transferring the tool 3a in X and Y -directions. The transfer means 9 comprise a first electric motor 9a for transferring the processing tool 3a in X-direction; and a second electric motor 9b for transferring the processing tool 3a in Y-direction, which is 20 perpendicular to the X-direction. The processing tool 3a is at one end of an arm which at said one end extends into the working area 21 and an opposite end of the arm is positioned outside the working area 21. The motors 9a, 9b are adapted to move the arm in order to move the processing tool 3a.
The processing tool 3a is a high pressure nozzle adapted to spray 25 liquid, typically water, containing abrasive material, with high pressure, e.g. 2000- 4000 bar against the container 5 to make a hole in the wall thereof.
0 Before the apparatus is attached to the container 5, the area at
CVJ
^ which the apparatus is attached is cleaned. Cleaning can for instance be car- ® ried out with high pressure water. It is conceivable that mechanical cleaning is Γ"» 30 used as an alternative, or in addition, to cleaning with water. Said cleaning is 1 carried out in order to prepare the apparatus 1 to be sealed against the con- tainer 5 with a sealing means 4, which is positioned tightly (water proof) co [£ against the surface of the container 5. The sealing means 4 is a seal in the £ form of an elastic flexible member (or construction) which surrounds the pro- 00 35 cessing tool 3a (as seen in Figure 3) and surrounds also the working area 21.
The sealing means 4 has preferably a circumferential shape and is e.g. made 5 of rubber.
After the apparatus 1 has been attached to the container 5 and the sealing means 4 has been positioned tightly against the container, the processing tool 3a is put into work to process the through hole 8 to the container.
5 Figure 6 shows an example of suitable geometry for the hole 8.
After the hole 8 has been processed, the processing tool 3a is moved away from the working area 21 in order that a valve arrangement 7 can be inserted in the working area and fixed to the site of the hole 8. The valve arrangement 7 is for emptying the container 5 at desired point of time. The valve 10 arrangement 7 comprises a valve (not shown) which can be opened and closed. When opened, liquid may pass the valve; and when closed liquid cannot pass the valve. The valve is not explained here in more detail, because the construction thereof can be of conventional type and known to persons skilled in the art. While processing the hole 8 to the container 5, the valve arrange-15 ment 7 is outside the working area 21, and more precisely preferably in a storage position inside a casing 23 above the working area 21, c.f. Figure 2 showing the valve arrangement 7 with dashed line in the storage position.
A transfer arrangement 19 associated with the valve arrangement 7 is arranged to transfer the valve arrangement from the storage position shown 20 in Figure 2 to the working area 21 below (the working area 21 is seen form below in Figure 3). The transfer arrangement 19 comprises an electric motor 19a adapted to lower the casing 23 with the valve arrangement 7 inside, along threaded guides 19b arranged around the casing. The electric motor 19a is arranged to rotate threaded wheels (not shown) which surround the threaded 25 guides 19b. When the threaded wheels (which are supported by the frame 20 of the apparatus) are rotated by the electric motor 19a, the casing 23, the valve 0 arrangement 7 and the threaded guides 19b move in the vertical direction with
CXI
^ respect to the frame 20 of the apparatus.
° The valve arrangement 7 is seen in more detail in Figure 9. The 30 valve arrangement 7 comprises a body 14, a flange part 15 attached at the 1 lower end of the body 14 and a cylindrical part 18 attached to the flange part ^ 15. The flange part 15 comprises a flange 15a and it is attached to the body 14 co [£ with threads. The cylindrical part 18 comprises outer threads 16 which attach ” the cylindrical part 18 to inner threads 22 of the flange part 15. The cylindrical 00 35 part 18 comprises further three lugs 33a, 33b, 33c forming three stop surfaces 10a, 10b, 10c and the flange part 15 comprises a flange 15a.
6
To fix the valve arrangement 7 at the site of the hole 8 of the container 5, the casing 23 is lowered so that the flange 15a of the flange part 15 contacts the outer surface 17 of the container 5 and the stop surfaces 10a, 10b, 10c at the lower end of the cylindrical part 18 become positioned beyond 5 the hole 8, see Figures 8-10. Thereafter the casing 23 is rotated with an actuator 13 (seen in Figure 2). A transmission element 25 in the form of a belt transfers rotation from the actuator 13 to the casing 23. In order to transfer rotational movement from the electric motor 13a of the actuator 13 to the valve arrangement 7, a gripper 26 is provided which engage with the valve arrange- 10 ment 7. The gripper 26 can be disengaged from the valve arrangement 7 in order to detach the valve arrangement 7 from the rest of the apparatus after the valve arrangement 7 has been fixed on place on the container 5. The gripper 26 is for example an expandable device the expansion and contraction of which is actuated with an actuator 30, which preferably is an electric motor.
15 When the gripper 26 is expanded, it grips the valve arrangement 7 and transfers rotational motion from the actuator 13 to the valve arrangement 7, and when the gripper 26 is contracted, no rotational motion can be transferred from the actuator 13, and the valve arrangement 7 is released from the apparatus and also from the casing 23.
20 When rotating the casing 23, the actuator 13 rotates the valve ar rangement 7. Flowever, rotation of the cylindrical part 18 is hindered, because the stop surfaces 10a, 10b, 10c are provided with protruding stoppers 12a, 12b, 12c which abut the wall of the hole 8. The stoppers 12a, 12b, 12c are elements which protrude from the stop surfaces 10a, 10b, 10c. The actuator 13 25 cannot turn the cylindrical part 18 more than a restricted angle (of e.g. 10 to 50 degrees), because the stoppers 12a, 12b, 12c hit against a wall portion of the 0 wall defining the hole 8 - as shown in Figure 8. This is because the distance c\i ^ R1 from the central axis of the cylindrical part 18 to the stoppers 12a, 12b, 12c ° is larger than the distance r1 from the central axis of the hole 8 to the wall por- Γ''' 30 tion of the wall defining the hole 8, see Figure 8. The stoppers 12a, 12b, 12c 1 are preferably cotter keys positioned in through holes made in the lugs 33a, 33b, 33c of the cylindrical part 18. To displace the stoppers 12a, 12b, 12c wither in said through holes, a force, having a direction of the stoppers and the axial £ direction of the cylindrical part 18, must be overcome. Before the casing 23 is ^ 35 put into rotation, the upper ends of the cotter keys are at a distance, relatively far, from the upper surface of the lugs 32a, 32b, 32c, i.e. from the stop surfac- 7 es 10a, 10b, 10c, and they (i.e. said upper ends) about the lower surface (not indicated with reference sign in the drawings) of the flange 15a, or, alternatively they are close to said lower surface,
Owing to the above described construction of the apparatus, when 5 the casing 23 is rotated, the flange part 15 rotates with respect to the cylindrical part 18, and during rotation the distance of the stop surfaces 10a, 10b, 10c to the flange part 15 and the distance L of the stop surfaces to the body 14 of the valve arrangement 7 become smaller causing eventually the wall of the container 5 to be compressed between the stop surfaces 10a, 10b, 10c and 10 the flange 15a. The shaded areas in Figure 8 show the stop surfaces 10a, 10b, 10c supporting the valve arrangement 7 against the inner surface 11 of the container 5. During said rotation of the casing 23, the cotter keys are displaced in the holes of the lugs 33a, 33b, 33c so that the upper ends thereof come closer to the upper surface of the lugs. This is because the lower surface of the 15 flange 15a presses against the upper ends of the cotter keys when rotating the casing 23 and the body 14 of the valve arrangement 7. Thanks to displaceable stoppers 12a, 12b, 12c in the form of e.g. said cotter keys, it is easy to mount the valve arrangement 7 to different containers 5 whose wall thickness may vary: the upper ends of the stoppers 12a, 12b, 12c will reach the wall of the 20 hole 8 regardless the wall thickness of the container 5 after the flange 15a initially has been positioned against the outer wall of the container.
As it is seen from Figure 9, when mounted, the valve arrangement 7 is supported by the flange 15 against the outer surface 17 of the container 5. The flange 15 is sealed against the outer surface 17 of the container 5 with a 25 ring seal 32, see Figure 9.
Figure 10 illustrates another shape of the hole 8’ in the container 5’ o and shows also cylindrical part 18’ having another design than the one shown
CVJ
^ in Figures 5 and 7 - 9. In Figure 10 only two stoppers 12a’, 12b’ are provided.
® Like in the embodiment of Figures 5 and 7-9, the distance R1 is larger than Γ"» 30 the distance r1. In Figure 10 applies additionally that the distance 2R1 be- | tween the stoppers 12a’ and 12b’ is larger than the smallest diameter d’ of the hole 8’. co [£ The invention has been described above only by an example and ^ hence it is submitted that the invention can be implemented in many various ^ 35 ways within the scope of the attached claims. It is conceivable that the cylindri cal part 18 has only one stop surface. Flowever, at least two stop surfaces (c.f.
8
Figure 10) are highly preferable in order to provide good support for the mounted valve arrangement 7. The stoppers 12a, 12b, 12c, 12a’, 12b’ need not be displaceable within holes in lugs 33a, 33b although this is preferable because it makes the mounting of the valve arrangement 7 very easy to per-5 form.
