Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0046] With the intention of better showing the characteristics of the present disclosure, embodiments of a device according to the present disclosure for the cleaning of vessels are described hereinafter by way of an example, without any limiting nature, with reference to the accompanying figures, wherein:

[0047] FIG. 1 schematically shows a device according to the present disclosure;

[0048] FIG. 2 on a larger scale and in more detail shows the section indicated in FIG. 1 by F2; and

[0049] FIG. 3 shows a practical embodiment of a cleaning element.

[0050] FIG. 1 schematically shows a sea-going vessel 1, the hull 2 of which is located in the water.

[0051] The hull 2 is provided with so-called bilge keels 3, which extend in a longitudinal direction of the vessel 1 on the location where the side 4 of the hull 2 changes into the bottom 5 of the hull 2.

[0052] The bilge keels 3 are installed perpendicular to the hull 2.

[0053] The hull 2, or at least the submerged sections of the hull 2, are treated with a non-toxic layer of paint based on a surface-treated coating.

[0054] In this case this surface-treated coating comprises a composite reinforced with glass flakes.

[0055] The coating is not only effective in preventing biofouling of the hull 2 of the vessel 1, but also that no biocides will be released when cleaning the hull 2 of the vessel 1. Moreover, the coating will not be damaged or wear off, such that practically no maintenance or repairs are necessary to the coating itself.

[0056] FIG. 1 also shows a device 6 for the cleaning of a submerged section of the hull 2 of the vessel 1.

[0057] According to the present disclosure, the device 6 comprises the following components: a platform 7 with a first cleaning module 8 and with a device 9 to place and move the cleaning module 8 against the side 4 of the hull 2 of the vessel 1; and a launch platform 10 with a second cleaning module 11 which can place the second cleaning module 11 against the bottom 5 of the hull 2.

[0058] As shown in FIG. 1, in this case there are two platforms 7 and two first cleaning modules 8 and two launch platforms 10 with two second cleaning modules 11. In other words, the device 6 is made symmetrically. This is not necessary for the present disclosure.

[0059] The platform 7 in the example shown is made as a vessel, such as for example a floating pontoon or workboat. However, this is not necessarily the case. The platform 7 could also be on the quay.

[0060] The device 9 to place and move the cleaning module 8 against the side 4 of the hull 2 can be realised in different ways. For the efficient operation of the device 6 it is sufficient if the devices 9 can move the cleaning module 8 up and down against the hull 2 of the vessel 1.

[0061] The launch platform 10 can be made as a kind of cage, in which the necessary equipment is installed and to which or in which the second cleaning module 11 can be installed.

[0062] This launch platform 10 is intended to be submerged in the water. As will be clear from the description, this launch platform 10 can be considered as an underwater engine room, also called a ‘submergable engine room’.

[0063] According to the present disclosure the second cleaning module 11 is connected via a first cable 12 to the launch platform 10 for the movement and control thereof.

[0064] FIG. 2 shows a section of the device 6 in more detail.

[0065] This figure shows that the platform 7 is provided with a control unit 13 to control the movement of the platform 7 and of the first cleaning module 8.

[0066] The launch platform 10 is connected to the platform 7, in particular to the control unit 13 of the platform 7, by a second cable 14 to control the launch platform 10.

[0067] It is clear that the launch platform 10 can also be controlled in other ways other than by the second cable 14 and the control unit 13.

[0068] It is also not excluded that the second cleaning module 11 is also controlled by the second cable 14.

[0069] However, in this case, the launch platform 10 is provided with a control unit 15 to control the second cleaning module 11.

[0070] The control is via the first cable 12. This cable 12 is what is called an “umbilical cable”, a rigid, thick and not very flexible cable 12 to send all the necessary control signals, electrical and hydraulic energy, etc. from the launch platform 10, in particular from the control unit 15, to the second cleaning module 11.

[0071] By working with the launch platform 10 for the second cleaning module 11, this first cable 12 can be kept much shorter than when the second cleaning module 11 were to be connected via the platform 7.

[0072] The first cable 12 will also be used to control the movement of the second cleaning module 11.

[0073] The launch platform 10 is also provided with propulsion device 16, such as for example propellers, rotors, thrusters or the like to move under water.

[0074] Furthermore, the launch platform 10 is provided with a stop 17 for the hull 2 of the vessel 1 in the form of one or more wheels, fender cushions or the like.

[0075] This will allow the launch platform 10 to come very close, up against the hull 2 of the vessel 1, without the possibility of damage, both to the vessel 1 and the launch platform 10.

[0076] As shown in FIG. 1, the two second cleaning modules 11 are connected to each other by a cable 18, the cable hereinafter referred to as the ‘connecting cable 18’.

[0077] This connecting cable 18 can be a regular cable and does not have to be a so-called “umbilical cable”. It will only be used for the physical coupling of the second cleaning modules 11 to each other and not for control, energy transfer or the like.

[0078] This cable 18 will be used to be able to move both cleaning modules by pulling, this will be explained later.

[0079] FIG. 3 shows a possible embodiment of a cleaning module 8, 11 in more detail.

[0080] The cleaning module 8, 11 comprises a frame 19 with a number of roller brushes 20 mounted therein, whereby the roller brushes 20 are driven by a motor 21, whereby the axles 22 of the roller brushes 20 extend horizontally and parallel with the hull 2 of the vessel 1 during operation.

[0081] The roller brushes 20 thus also extend parallel to each other and are placed in a sort of staggered set-up.

[0082] In this case there are three roller brushes 20, which can rotate around their axles 22. It is also possible there are only one, two, four, five or more roller brushes 20.

[0083] The roller brushes 20 overlap slightly in a direction perpendicular to the axles 22, such that a completely uninterrupted cleaning surface is obtained when the cleaning module 8, 11 is moved over the hull 2 of the vessel 1.

[0084] In this case the launch platforms 10 also contain one or several floats 23 or floating elements or the like which will generate an upthrust. In some embodiments, the upthrust of these floats 23 is adjustable. This could be realised, for example, by making the floats 23 in the form of air cushions or the like, which can be filled with more or less air in order to regulate the upthrust of the floats 23.

[0085] The operation of the device 6 is very simple and as follows.

[0086] The platforms 7 and the launch platforms 10 first sail to a vessel 1 to be cleaned.

[0087] The platforms 7 position themselves on either side of the vessel 1 with the first cleaning modules 8 oriented to the side 4 of the hull 2.

[0088] The launch platforms 10 are placed on the level of the bottom 5 of the hull 2, by possibly raising or lowering them in the water such that they are at the right level, whereby the second cleaning modules 11 are located on the level of the bottom 5 of the hull 2. The floats 23 can be used for this.

[0089] The stops 17 will be up against the hull 2 or bilge keels 3.

[0090] Then the whole device 6 moves along the vessel 1, as shown in FIG. 1, whereby the first cleaning modules 8 make contact with the side 4 and the second cleaning modules 11 with the bottom 5.

[0091] It is of course also possible that the device 6 is set up at a certain location and that the vessel 1 sails to it.

[0092] The device 6 can then be put into operation. The roller brushes 20 of the cleaning modules 8, 11 are put into operation by switching on the motors 21.

[0093] The cleaning modules 20 will suck themselves, as it were, onto the hull 2 of the vessel 1.

[0094] The cleaning of the hull 2 can then be started: the first cleaning modules 8 are moved in an upward and downward movement against the side 4 by the platforms 7.

[0095] They will move up against the bilge keels 3, to clean the hull 2 at the level of the bilge keels 3 and the upward facing side of the bilge keels 3 themselves.

[0096] The second cleaning modules 11 are moved back and forth over the bottom by alternately rolling up and down or extending and retracting the first two cables 12, in such a way that the two second cleaning modules 11, by the operation of the connecting cable 18 between both second cleaning modules 11, are moved synchronously back and forth over the bottom 5 of the hull 2.

[0097] The second cleaning modules 11 will also move up against the bilge keels 3 to thus clean the hull 2 on the level of the bilge keels 3 and the downward facing side of the bilge keels 3 themselves.

[0098] After one upward and downward movement of the first cleaning modules 8 and one lateral back and forth movement of the second cleaning modules 11 the biofouling will be removed.

[0099] Possibly a second movement of the cleaning modules 8, 11 can be executed. The device is then moved to a following section of the hull 2 to be cleaned. Alternatively, the vessel 1 can also be repositioned in relation to the device 6.

[0100] The cleaning modules 8, 11 are moved in a similar way as described above on the next section of the hull 2 to be cleaned.

[0101] It is also possible that the cleaning modules 8, 11 make a continuous upward and downward and back and forth movement, while the device 6 moves slowly along the vessel 1 or the vessel 1 moves slowly through it.

[0102] In this way, the hull 2 and bilge keels 3 can be cleaned quickly. To clean the front and the back of the vessel, divers can be used. These sections constitute only a small share of the total surface area of the vessel.

[0103] Although in the example shown above, the cleaning modules 8, 11 comprise roller brushes, it cannot be excluded that the first and second cleaning modules 8, 11 comprise a frame 19 with a number of sponges mounted therein. By the upward and downward and back and forth movement of the cleaning modules 8, 11 against the hull 2 of the vessel 1, the sponges can be rubbed against the hull 2 of the vessel 1 to thus clean the hull 2.

[0104] The present disclosure is not limited to the embodiments described as an example and shown in the drawings, but a device according to the present disclosure for the cleaning of vessels can be realised in all kinds of forms and dimensions, without departing from the scope of the present disclosure.
