Definitions
- unloading equipment for a flat top barge More precisely there is provided unloading equipment for a flat top barge having a deck.
- the invention also includes a method for unloading of the barge.
- a "flat top barge” is in this context defined to be a barge that has its loading deck close to or above the sea line.
- the flat top barge may be a conventional non-propelled or a self- propelled barge.
- the barge When used for transport of sand, for instance for recouping land from the sea, the barge may be loaded by pumping
- the drainage may typically be done through perforations typically in the form of slits or through geotextiles in the retaining wall, or through an agricultural type perforated pipes on or close to the deck.
- the purpose of the invention is to overcome or reduce at lest one of the disadvantages of the prior art.
- unloading equipment for a flat top barge having a deck, wherein at least one water supply outlet is provided at, in or above the deck for slurrification or flushing of sand that is present on the barge.
- the water supply outlets may include flow regulating items such as orifices or valves.
- the water supply outlets may communicate with a pipe that is positioned on, under or above the deck. In this way a pipe may have a plurality of water supply outlets that may be positioned on the deck, thus providing a low cost option of unloading equipment. More than one pipe may be advantageous, particularly on larger barges.
- a water supply outlet may be supported by equipment separate from the barge.
- a fixed or floating gantry system or an excavator placed on the barge or on an adjacent barge, may for instance be useful for supporting the water supply outlet and a tubular.
- a water supply outlet depending on its position relative to the barge, may require connections through the pipe and/or the tubular in order to be connect- able to a water pump.
- the water pump may be positioned on or outside the barge. If positioned outside the barge, the water pump may be better suited for serving more than one barge as the water pump is only connected to the barge during the unloading operation.
- the flat top barge may have a retaining wall for keeping the sand in position on the barge during loading and transport. At least part of the retaining wall may be tiltable or removable in order to facilitate unloading by fluidizing the sand .
- the retaining wall or the deck may have an opening for discharge of fluidized or flushed sand leading to the outside of the barge.
- the opening should be closable.
- the opening does not need to be closable for unloading purposes.
- the closable opening may be equipped with a valve. Any type of valve suitable for the purpose may be used.
- the valve may be remotely controlled for instance by a hydraulic ram.
- the water supply outlet is normally
- the barge may have a retaining wall and the method may include :
- the unloading equipment and the method according to the invention provide a substantial reduction in time and cost for unloading sand from a flat top barge.
- Fig. 1 shows a perspective view of a flat top barge with equipment according to the invention
- Fig. 2 shows to a larger scale a pipe with water supply
- Fig. 3 shows an opening in a retaining wall of the barge, where a valve is positioned at the opening
- Fig. 4 shows a perspective view of a self-propelled barge
- Fig. 5 shows schematically a front view of a barge that is positioned under a gantry carrying a water supply outlet
- Fig. 6 shows schematically a front view of a barge that is positioned adjacent to another barge with an excavator carrying a water supply outlet.
- the reference numeral 1 denotes a flat top barge having a deck 2.
- a retaining wall 4 that extends upwardly from the deck 2 encloses the deck 2 and serves to keep sand in position on the deck 2 during loading and transport .
- a pipe 6 is positioned centrally on the deck 2.
- the pipe 6 is equipped with a plurality of water supply outlets 8 along its length.
- the water supply outlets 8 are shown in the form of flanged stud pipes 10.
- the pipe 6 is during unloading connected by a tubular 12, preferably in the form of a tube, to a not shown water pump.
- the retaining wall 4 is provided with a number of openings 14 for discharge of slurrified sand. In this preferred
- each opening 14 is provided with a valve 16 and are thus closable.
- the valve 16 is pivotable about a hinge 18 and operated by a hydraulic ram 20. In fig. 3, the valve 16 is shown in an open position.
- the pipe 6 When unloading the barge, the pipe 6 is connected to the not shown water pump via the tubular 12. Water is pumped into the sand through the water supply outlets 8 fluidizing the sand. The valves 16 are opened, letting the fluidized sand flow out of the barge 1 via the openings 14.
- Fig. 4 shows a self-propelled barge 1 equipped with the same equipment as that shown on the barge 1 in fig. 1.
- the self- propelled barge 1 has a super structure 22.
- the self- propelled barge 1 is well suited to have a not shown inboard water pump for providing the water supply outlets 8 with water .
- a gantry 24 on floats 26 is equipped with a relatively to the gantry 24 movable water supply outlet 8.
- the water supply outlet 8 is connected to a tubular 12, see fig. 5.
- the water supply outlet 8 is in fig. 6 shown on an excavator 28 that is carried by a separate barge 30.
- the gantry 24 and the excavator 28 are examples of support equipment 32.
