Definitions

  • the buoyancy of the at least one buoyant body is larger than the combined weight of the container, the buoyant body itself and the equipment and personnel present at the container.
  • the container with the equipment may be floated to a position next to the ship to be cleaned with the re- suit that the water suction line and the water pressure line may have shorter lengths as the distances between the pump and the filter device on the one hand and the cleaning unit on the other hand are smaller when the container is close to the ship.
  • the at least one buoyant body has a length and a width corresponding to the length and width of the container, and the at least one buoyant body has corner fittings.
  • the corner fittings on the buoyant body can be locked to similar corner fittings on the container, such as by using twist-locks or other standard container corner locking equipment.
  • An advantage of this is that the buoyant body can be connected with the container by standard means and without exceeding the footprint of the container, such as 6.1 m x 2.44 m (20' x 8') for a 20' ISO standard container, or 12.2 m x 2.44 m (40' x 8') for a 40' ISO standard container.
  • the hull cleaning system is thus easy to store as it fits into standard container systems, and it is easy to move as standard container cranes can be used.
  • the container is provided with two buoyant bodies.
  • the stability of the system in floating condition is improved by using two buoyant bodies instead of only a single buoyant body, because the two buoyant bodies may be located with mutual separation below the container and thus provide a higher righting moment.
  • either end of the container is locked to one of the two buoyant bodies, the buoyant bodies being located with their length direction extending in the width direction of the container, when the system is in its floating operating condition.
  • the container and the two buoyant bodies are thus in an H-type configuration when viewed from above, and this provides a high degree of floating stability.
  • This configuration also provides free deck space outside the footprint of the container, and better ability for personnel to move around and assist di- vers and handle moorings etc. during the cleaning operation.
  • the two buoyant bodies are spaced apart and a floor structure, preferably a grating, extends between the buoyant bodies in the area next to the container.
  • the grating increases the available deck space.
  • the hull cleaning system preferably has an inactive condition, in which at least the cleaning unit, the water suction line, the water pressure line, the centrifugal pump, the at least one filter device, a generator and possibly diving equipment are stored within the container.
  • the at least one buoyant body can be positioned on the container with the length direction extending in the length direction of the container.
  • the at least one buoyant body can be positioned on top of the container or on the bottom side of the container, or in case of two or more buoyant bodies both on the bottom side and on the top side of the container. Two buoyant bodies can alternatively be locked together on top of one another. This alternative is preferred in cases, where the buoyant bodies have a height corresponding to about 50% of the height of the container.
  • the complete hull cleaning system is easily stored in a safe manner.
  • the container is provided with diving equip- ment.
  • diving equipment in the container of the hull cleaning system it becomes possible to dispense with using a separate diving ship.
  • the hull cleaning system is self-propelled by providing one of the buoyant bodies with an engine driving a water pump, and providing the buoyant bodies with submerged nozzles for ejecting pressurized water delivered by the water pump.
  • a hull cleaning system is generally designated 1 and includes in a stored away condition various parts located inside a container 10 and two buoyant bodies 11 located outside container 10.
  • the two buoyant bodies 11 can be arranged in different ways with respect to the container in the stored away condition.
  • the buoyant bodies can be stored separately from the container.
  • the buoyant bodies can be arranged below and on top of the container, as it is illustrated in Fig. 1, both buoyant bodies can be arranged on top of the container, or both buoyant bodies 11 can be arranged below the container 10. In the first embodiment of Fig. 1 the buoyant bodies have sufficient height to provide the required buoyancy.
  • the buoyant bodies have larger height than in the first embodiment, namely a height corresponding to about half the height of container 10.
  • the length and the width of the buoyant body 11 correspond to the length and the width of the container 10.
  • Container 10 may have a freely selected size, but it is preferably an ISO standard container of 20' in length, or possibly of 40' in length.
  • the container 10 has standard corner fittings 12, and the buoyant body 11 is provided with the same type of standard corner fittings 12 at each corner in the same manner as such corner fittings are provided on the container.
  • the corner fittings on both the container and the buoyant body 11 may consequently be interlocked by container standard brackets or container standard twist-locks. In the interconnected state a container crane or another container lifting device can in a single operation lift container 10 and buoyant bodies 11, and the management of the system on shore is thus particularly simple.
  • the power generator may be a generator del i- vering power at 230 V and 50 Hz, where the generator is driven by a di- esel engine.
  • the diesel engine and the generator are preferably mounted in a frame structure so at to be movable as a unit.
  • a power generator of this type is available from EuroCommerce ApS, Denmark in a 6 kW version.
  • the centrifugal pump may be a FOX Portable Pump from Rosen- bauer International, Austria of the type PFPN having a capacity of 1000 liters per minute at a delivery pressure of 15 bar and 1600 liters per minute at a delivery pressure of 10 bar.
  • This centrifugal pump is a single-stage pump provided with an automatically controlled double action piston pump for priming the centrifugal pump.
  • the pump is driven by a BMW 2 cylinder four-stroke piston engine providing an output of 50 kW at 4500 rpm.
  • a water suction line 5, typically a steel-armored hose is connected to the suction side of centrifugal pump 6.
  • a water pressure line 7 is connected to the pressure side of centrifugal pump 6 and extends to a filter device 8, such as an automatic filter of the type AF 75 S or AF 76 S and the make Mahle, available from the company Filterteknik, Denmark. It is possible to use only a single filter device 8, but preferably several filter devices are used in series as illustrated in Fig. 6, where the outlet from the first filter device is connected with the inlet of the second filter device, and so forth for the four filter devices. It is also possible to couple the filter devices in parallel.
  • the water pressure line 7 extends to a first connection 23 on a cleaning unit 2 (fig. 7).
  • the first connection 23 has an inlet opening to a drive 4 for cleaning brushes 3.
  • the drive is a water turbine where the turbine wheel within the drive housing receives the pressurized water at the periphery of the wheel and delivers spent water at the center of the wheel where a central exit pipe extends via a pipe bend to a water outlet 9.
  • Water outlet 9 is preferably directed to face opposite to the desired path to be followed by the cleaning unit.
  • the pipe bend and the pipe section extending between the bend and water outlet 9 may be mounted onto the exit pipe from the drive housing in a swiveling manner so that the pipe section can be easily turned with the water outlet facing in the opposite direction, as is illu- strated in broken lines in Fig. 7.
  • Suction openings 26 on the inner side of the cleaning unit 2 are connected to water suction line 5 via pipes 25, which extend from the individual suction opening 26 to a second connection 24 for water suction line 5.
  • the second connection 24 is common to all suction openings. In the illustrated embodiment there are four suction openings and the second connection 24 is located to one side of the cleaning unit. There can alternatively be two or three suction openings, or more than four suction openings, such as five or six suction openings, and the pipes 25 can be arranged in other manners.
  • the pipe section with the second connection can for example be located at the middle of the cleaning unit.
  • the cleaning unit 2 may have a protruding skirt along its periphery so that the skirt forms a cup-shaped volume around cleaning brushes 3.
  • the cleaning unit is on its outer side provided with handles 22.
  • the handles may be fixed structures, or they may be flexible structures like pieces of rope, according to what the divers prefer.
  • the cleaning unit may on its inner side have distance members, such as supports with wheels.
  • the distance members can maintain a distance to the hull surface so that there is a certain free space between the hull and the free end of the skirt.
  • the skirt can have protruding portions along its free end, which protruding portions act as distance members.
  • Another alternative is to provide the skirt with side openings through which water can be drawn into the cup-shaped volume around the cleaning brushes.
  • the cleaning unit 2 can be stored in the container, and typically two cleaning units are stored. When the cleaning unit is to be used, it is moved out to a buoy 20 located next to the side of the ship to be cleaned.
  • the water pressure line 7 is connected to the first connection 23 and the water suction line 5 is connected to the second connection 24 on the cleaning unit.
  • the cleaning unit may be connected to buoy 20 via a wire having a length sufficient to allow the cleaning unit to follow the cleaning path on the hull.
  • centrifugal pump 6 When the unit is in position at the hull surface centrifugal pump 6 is engaged and water is drawn in through suction openings 26 and via water suction line 5 to the pump 6, which delivers the pressurized water via filter devices 8 and water pressure line 7 to the drive 4 for the cleaning brushes.
  • the water jet leaving drive 4 via water outlet 9 propels the cleaning unit in the direction of the cleaning path along the ship hull.
  • the container has a compressor for providing divers with air via umbilical 19, and other types of diver equipment may be present in the container, such as pressure bottles 17 for scuba diving or pressure ves- sels for special air blends, like helium.
  • Communication equipment 18 allows contact with the divers from the control desk in the container.
  • the communication equipment may include recording equipment, such as video recording.
  • the comm unication equipment may include a laptop computer. Shelves 21 for stores may hold additional diving equipment.
  • Fouling material scraped off from the filter parts leaves filter devices 8 from a bottom outlet.
  • the fouling material may be collected in bags at the filter devices and carried out of the container, or it may be conveyed in piping or chutes from the filter devices to a storage site outside the container.
  • the storage site is in the buoyant bodies 11.
  • the storage site is a separate container located on top of buoyant body 11 or a separate container floating next to buoyant body 11.
  • water suction line 5 is provided with an additional suction opening with a control valve, which may partially or fully open or close the additional suction opening.
  • the additional suction opening may be opened in case the cleaning unit has a need for consuming a higher flow rate of pressurized water from the water pressure line than the flow rate of water from the suction openings 26.
  • the additional suction opening can be located below the water surface at any appropri- ate location. It is also possible to provide pipes 25 leading to the second connection 24 with an additional opening controlled by a control valve. This additional opening may be facing away from the hull, when the cleaning unit is in operation, and the control valve may have a control handle operable by a diver.
  • the skirt may have side openings that can be opened or blocked according to need.
  • the water pressure line is downstream of the filter devices provided with a waste gate that may be opened in case the cleaning unit has a need for consuming a lower flow rate of pressurized water from the water pressure line than the flow rate of water from the suction openings 26.
  • the nozzles are fixedly mounted in bodies 11 and directed in different directions, and the supply of water to the nozzles is then controlled so that only nozzles pointing away from the desired direction of movement is supplied with water.
  • An preferred embodiment has 8 nozzles located with two nozzles at each of the four outermost corners of the bodies 11. The two nozzles at the individual corner have outflow openings directed about 90° apart.
  • One of the openings can e.g. be flush with the short side wall of the body 11 and the other of the openings can e.g. be flush with the long side wall of the body 11.
  • the nozzles are via pressure lines connectable to the pressurized water supply from the water pump.
  • the pressure lines are provided with control valves, and these valves are operable from a control position within container 10.
  • the underwater cleaning unit 2 has circumferentially extending a hollow structure 31 providing buoyancy to the cleaning unit.
  • the hollow structure comprises a closed pipe running along the entire periphery.
  • the pipe is preferably of a plastic material having a density of about 0.98 (980 kg/m 3 ), but other densities higher than 1 are also possible.
  • the volume of the hollow structure is dimensioned so that the cleaning unit as a whole has a little negative buoyancy, preferably at about 2 kg.
  • the hollow structure 31 is provided with four wheels 32 as illustrated in Fig. 10. In operation the wheels can abut the surface being cleaned.
  • the suction pipes 25 end in suctions openings 26 located between hollow structure 31 and the plate body carrying the brushes.
  • the cleaning brushes 3 are mounted on their drive shaft with a possibility of moving in the axial direction of the shaft.
  • the rotational movement of the brushes on the side of the hull causes a lower pressure just in front of the brush so that the brush is sucked towards the side of the hull.
  • the floating mounting of the brushes on the drive shafts with the possibility for individual axial movement of the brushes causes the brushes to automatically adapt to curvatures in the ship hull being cleaned. Details from the above-mentioned embodiments may be combined into new embodiments within the scope of the patent claims, and the details may be varied within the scope of the patent claims. It is as an example possible to use a cleaning unit having only one or two cleaning brushes, or four or five or more cleaning brushes.
  • the water suction line may be divided into several parallel suction lines, and/or the water pressure line may be divided into several parallel water pressure lines. It is also possible to simultaneously use two or more cleaning units supplied by the centrifugal pump and the filter devices via separate suction and pressure lines, the suction lines being united in a manifold upstream of the centrifugal pump, and the pressure lines being divided into individual lines in a manifold downstream of the filter devices.
  • the cleaning unit can be driven in the cleaning direction by other means than the water outlet from the drive, such as by being pulled, or by being driven by wheels.
