Definitions

  • the present disclosure relates to vehicles for storing container ship hatch covers and method of unloading and loading a container ship using such vehicles.
  • a lifting hatch arrangement does not require additional mechanisms in the ship and does not require space on the vessel into which the hatch cover can fold or roll.
  • the hatches When unloading or loading containers or other cargo at the port facility (or container terminal) the hatches must be removed and stored during the process of unloading/loading the holds.
  • ship to shore cranes are provided on the quayside, which can be positioned and repositioned along the vessel length to unload and load containers from each hold of the vessel using a spreader or other suitable means.
  • the most frequent type of crane is the ship to shore gantry crane (SSGC) running on rails with a gauge of 25 to 35m, with waterside hinged strutted twin mono-box boom reaching out over the widest vessel which can be
  • the boom extends beyond the SSGC crane rails forming a back-reach boom of 20 to 30m.
  • One or more trolleys operate along the boom.
  • Ultra Large Container Vessels typically have four covers (occasionally five covers) over each of the central holds, although the number can reduce to 3 covers per hold where the vessel narrows at the prow and the stem-most holds have no covers.
  • Each vessel will likely have a slightly different lay-out, but generally a single hatch cover can be lifted off the vessel as soon as it is cleared of the containers stacked upon it and could if operational needs required be returned in advance of other hatches being cleared.
  • Hatch covers can weigh up to 50 tonnes, and measure in the region of l.8m high and can have a footprint of l4m (perpendicular to the quayside) by between 12.8m and l4m (parallel to the quayside), although sizes vary depending on the ship.
  • hatch covers cannot be readily transported at ground level without disrupting a vessel unloading operation. Hatch covers are therefore stored on the ground under the crane in a designated area to suit the terminal operations, often under the back reach, so that they can be readily moved by the crane. Since the covers have a large footprint, storing the hatch covers under the crane creates a large zone on the dock apron that cannot then be used by land based vehicles, for example to move unloaded containers or other cargo away from the berth. [0009] The footprint can be reduced by stacking hatch covers on top of each other, but there remains a large unusable section of the apron that can affect dock-side traffic and reduce the efficiency of unloading/loading processes. Further, hatches on a ship are not interchangeable and need to be returned to the same location.
  • the order of the stack dictates the order that the hatch covers must be returned to the ship.
  • the number of standard SSGCs operating in close proximity to a ULCV or similar vessel means that when hatch covers are placed in the designated area, there is insufficient room on the apron (i.e. between the cranes and hatch covers) for vehicles to safely pass therebetween. Therefore the normal route for horizontal transporters is to use a one-way corridor with up to six lanes of trailers queuing under the crane hooks between the legs. This could be more efficient if another one way corridor was available under the back-reach. However, space for additional one way corridors is limited by the presence of hatch covers.
  • the designated stacking area for the hatch covers is often located between the legs of the ship-to-shore gantry (SSGC).

  • the present invention relates to a vehicle adapted to store hatch covers from a container ship, comprising a gantry for supporting at least one hatch cover from a container ship and a motor operable to cause the at least one hatch cover from a first location to a second location, which is different from the first location.
  • hatch covers lifted off of a container ship can be offloaded
  • the hatch covers can be moved away from a working area of the apron so as to avoid obstructing traffic lanes and crane hoists. A container ship can therefore be loaded and unloaded faster and more efficiently.
  • the motor of a vehicle is operable to move the vehicle.
  • a vehicle comprises a first trolley on the gantry, the first trolley adapted to support the at least one hatch cover and being operable to be driven, by the motor, between the first location and the second location.
  • the vehicle further comprises a second motor to move the vehicle.
  • the gantry of a vehicle comprises an upper level and a lower level, the first trolley being on the upper level of the gantry, and wherein the vehicle further comprises a second trolley on the lower level of the gantry.
  • a vehicle with an upper and lower level for a gantry can store more hatch covers without increasing the footprint of the vehicle, while also allowing access to hatch covers on one level independently of hatch covers on the other level.
  • the first location is a first hatch cover loading area and the second location is a first hatch cover storage area

  • the gantry includes a container storage area.
  • a container storage area for storing a container.
  • container off loaded from a on top of a hatch cover of a ship can be stored on the gantry so as to avoid storing that container on the apron if there is no apparatus immediately ready to remove that container. This avoids blockages to transport lanes and avoids congestion, which itself improves the efficiency of a process of loading/offloading a container ship.
  • the gantry has a ground clearance of at least 5.7m. More preferably, the gantry has a ground clearance of between 5.7m and l4m. Vehicles, such as AGVs and ALVs, can therefore pass beneath the gantry. This minimises the distance that the hatch covers must move as the vehicle can straddle a transport lane, thereby storing one or more hatch covers in the footprint of the transport lane without hindering movement of dock-side vehicles (such as the AGVs and ALVs).
  • dock-side vehicles such as the AGVs and ALVs
  • the present invention relates to a method of unloading a container ship, comprising unloading containers from the deck of a container ship, using a crane, to a container loading area beneath a boom of the crane on a quayside; removing a hatch cover from the container ship using the crane, and placing the removed hatch cover on a gantry of a vehicle for supporting hatch covers; moving the removed hatch cover away from the container loading area using the vehicle for supporting hatch covers.
  • the hatch covers can be moved away from a working area of the apron, by the vehicle for supporting hatch covers, so as to avoid obstructing traffic lanes and crane hoists.
  • a container ship can therefore be loaded and unloaded faster and more efficiently.
  • placing the removed hatch cover on a vehicle includes placing the hatch cover on a first trolley that is on top of the vehicle at a first hatch cover loading area, and moving the hatch cover includes moving the trolley from the first hatch cover loading area to a first hatch cover storage area on top of the vehicle.

  • the hatch cover vehicle 1 can operate with any crane suitable for removing and replacing hatch covers. Typically, such cranes also unload and load containers and other cargo.
  • the hatch cover vehicle 1 is particularly advantageous when used in ship-to-shore equipment that includes at least one ship-to-shore gantry crane (SSGC) as the legs of such cranes and the water line (i.e. the cope of the dock) define a limited apron that can be used for the unloading and loading processes. It is therefore advantageous to keep the apron as free as possible from obstacles.

  • ship-to- shore equipment includes a SSPC having two booms mounted between two legs, with one leg on either side of a berth, such as in the arrangement shown in WO2017/071736 Al the contents of which are incorporated herein by reference.
  • the hatch cover storage vehicle 1 (HCV 1) includes a frame that supports a gantry
  • the frame is a two sided frame with supports 2a and 2b with the gantry therebetween.
  • Each support 2a, 2b comprises two column legs linked at the base by a beam and secured at the head to the soffit of a rectangular gantry frame 3.
  • the base of the side supports 2a, 2b includes a drive system 4, such as a motor and wheels driven by the motor, to allow the hatch cover vehicle, HCV 1, to move at least parallel to the cope of the berth (i.e. an edge of a quayside).

  • the HCV 1 units can operate between the crane legs and/or under the cantilever back-reach depending upon the terminal preference.
  • the soffit (i.e. the underside) of the gantry 3 is at a height such that land based container transport equipment can travel beneath the gantry 3 of the hatch cover vehicle 1.
  • the gantry 3 is at least 5.7m above ground level (i.e. the soffit is at least 5.7m high). This allows Automated Guided Vehicles, AGVs, (or Automated Container Transport Vehicles, ACTVs) and trailers to pass beneath the gantry 3. It is more preferable that the gantry 3 is at least 1 lm above ground level, thereby also allowing, for example, Automated Lifting Vehicles, ALVs, to operate beneath the gantry 3.
  • the height of the gantry 3 is limited by the height of the hoist (hook, spreader or hopper) of the crane - the gantry 3 should not interfere with the movement of the hoist along the boom of the crane. Accordingly, a maximum height clearance to the underside of soffit of the gantry 3 over the ground can be l4m.

  • Fig. 1 shows access to the gantry 3 by way of stairs.
  • Other ways to access the platform 8, such as stairs or an elevator, and the gantry 3, such as a ladder or an elevator, will be apparent to a skilled reader and are within the scope of the invention.
  • the other side support 2b does not include a control station 6, but in some aspects still includes access to the gantry 3.
  • the HCV 1 has clearance between the two side supports 2a, 2b to allow land based container transport equipment to move between the side supports 2a, 2b. Allowing land based container transport equipment to move between the side supports 2a, 2b avoids the footprint of the hatch covers 9 being un-useable to the land based container transport equipment.
  • An HCV 1 will position the gantry 3 over a container loading area when awaiting a hatch cover. As the container loading area is beneath a boom of a crane, a hoist of a crane can lower a hatch cover 9 onto the gantry 3 of the HCV 1. Once one or more hatch covers 9 have been placed on the gantry 3 as a hatch cover stack, the hatch cover vehicle 1 travels the minimum distance to take the hatch cover stack clear of the crane boom operation. This allows the hatch covers 9 to remain on- hand for when they are to be replaced, while improving the efficiency, in terms of time and mechanical work, for the process.
  • the hatch cover vehicle 1 preferably positions the hatch covers 9 proximate the crane leg 10 and on a line that extends perpendicular to the edge of the quayside 19 and through a portal crane leg 10. With the vehicle hatch cover 1 in such a location, the side supports 2a, 2b do not restrict movement of land based container transport equipment more than the crane leg 10 itself.
  • ULCV typically have four or five hatch covers over each central hold, which each weigh between 40 and 50 tonnes.
  • the hatch cover vehicle 1 is able to store up to two hatch covers 9, stacked on top of one another on the gantry 3. Accordingly, a maximum of three hatch cover vehicles 1 would be sufficient to store the hatch covers 9 for one hold of a ULCV with up to six hatch covers 9.
  • the HCV 1 is able to store three or more hatch covers. The number of HCV 1 units will depend upon the number of cranes operating over the vessel, the way the vessel is loaded and adjusting operating sequence of the quay cranes so that the removal of hatch covers is phased. In some cases when all of the hatch covers are to be removed from a hold one or more of the hatch covers may be left in place or returned to the vessel during this operation. If needed, more HCVs may be provided.
