Description
- The present invention relates to an apparatus for loading or unloading cargo on or from a ship mooring at a quay wall of a harbor, and more particularly to an apparatus for loading and unloading cargo at a sea-side of a ship mooring at a quay wall, thereby enabling cargo to be loaded or unloaded simultaneously at both sides of the container ship by both cargo-handling apparatuses at the sea-side and the land-side.
- In general, marine transportation using a container ship is advantageous in that the marine transportation can carry more cargo and requires less cost in comparison with transportations by other transport means. Countries surrounded by the sea like the Republic of Korea have been considerably dependent on the marine transportation in a trade with foreign countries.
- Particularly, the marine transportation industry is currently in pursuit of larger ships, in order to increase the quantity of cargo transported by each ship, thereby reducing physical distribution cost and securing economical efficiency. As a result, harbors are required to expand their facilities for mooring and cargo-handing.
- However, most harbors have linear quay walls and cargo-handling equipment such as cranes located only on the land. Therefore, cargo-handling has no choice but to be performed only at one side of the a ship, that is, only at a quay-side or land-side of a ship mooring at the quay wall.
- In this case, the cargo-handling capability is proportional to the capacity and number of cranes which take part in the cargo-handling. However, it has been very difficult to expand the cargo-handling capability in the conventional harbors, since there is a limit to the number of cranes which can be simultaneously operated at the same quay-wall in the conventional harbors, due to restriction to the space which can be occupied by combination of cargo-handling systems, movement lines of transport vehicles, etc.
- Further, the time for which a ship stays at a quay wall is proportional to the size of the ship or the quantity of cargo carried by the ship. Therefore, larger ships deteriorate availability of a quay wall and increase the physical distribution cost.
- Therefore, the present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an apparatus which can load or unload cargo at a sea-side of a ship mooring at a quay wall, thereby enabling cargo to be loaded or unloaded simultaneously at both sides of the container ship by both cargo-handling apparatuses at the sea-side and the land-side.
- It is another object of the present invention to provide an apparatus for loading and unloading cargo at a sea-side of a ship, which includes ballast tanks for rising and sinking a barge of the apparatus and cushioning chambers under the ballast tanks for effectively absorbing possible impact when the ballast tanks are settled on the seabed.
- It is yet another object of the present invention to provide an apparatus for loading and unloading cargo at a sea-side of a ship, which has drawbridges each having length, inclination, and height, which can be freely adjusted according to the width of the container ship, the height of the quay wall, and the depth of the sea, so that the drawbridges can be rapidly installed and used regardless of the surroundings.
- In order to accomplish these objects, there is provided an apparatus for loading and unloading cargo at a sea-side of a ship, the apparatus comprising: a barge having a mooring side corresponding to one side of the ship; a barge anchoring unit for anchoring and releasing the barge at and from a predetermined place; at least one container crane disposed on an upper surface of the barge and being movable in a longitudinal direction of the barge; and at least one drawbridge for connecting an end of the mooring side of the barge to the quay wall.
- Preferably, the barge anchoring unit comprises: a plurality of ballast tanks provided at a lower surface of the barge; and a pumping unit for filling and discharging seawater in and from the ballast tanks.
- It is also preferred that each of the ballast tanks has a cushioning chamber disposed under the ballast tank.
- More preferably, the drawbridge comprises: a bridge deck connected between the quay wall and the barge, the bridge deck having a first end connected to the barge in such a manner that the bridge deck can pivot up and down about the first end of the bridge deck; a support tower installed on the barge; and a deck holder assembly having a first end coupled to a side surface of the bridge deck and a second end fixed to an upper portion of the support tower, so as to fold and unfold the bridge deck into and from the barge.
- The deck holder assembly may comprise: a cylinder hinged to the upper portion of the support tower; and a piston having a first end connected to the cylinder and a second end hinged to the side surface of the bridge deck.
- The drawbridge may further comprise a wire fixedly connecting the upper portion of the support tower to the barge.
- Preferably, the bridge deck has a second end opposite to the first end of the bridge deck, and the drawbridge further comprises a plurality of roller bearings provided under the second end of the bridge deck, the roller bearings being in contact with the quay wall to connect the second end of the bridge deck to the quay wall when the drawbridge is unfolded.
- The bridge deck may further comprise a strut installed at the second end of the bridge deck in contact with the quay wall.
- More preferably, the apparatus may further comprise a tugboat for tugging the barge to a location at which the mooring side of the barge is disposed adjacent to the sea-side of the ship.

FIG. 1 is a top view of an apparatus for loading and unloading cargo at a sea-side of a ship according to the present invention,FIG. 2 is a sectional view of the apparatus shown inFIG. 1 , andFIG. 3 is an enlarged partially-sectional view of a ballast tank shown inFIG. 2 . - As shown in FIGS. 1 to 3, an apparatus for loading and unloading cargo at a sea-side of a ship according to the present invention includes a
barge 10 having amooring side 11 corresponding to one side of acontainer ship 70, abarge anchoring unit 20 for anchoring or releasing thebarge 10 at or from a predetermined place, at least onecontainer crane 30 disposed on an upper surface of thebarge 10 and being movable in a longitudinal direction of thebarge 10, anddrawbridges 40 for connecting ends of themooring side 11 of thebarge 10 to thequay wall 50. - Here, the
barge anchoring unit 20, which anchors or releases thebarge 10 at or from a predetermined position in the sea, includes a plurality ofballast tanks 21 provided at a lower surface of thebarge 10 and apumping unit 22 for filling or discharging seawater in or from theballast tanks 21. - Further, the
container cranes 30 are installed on a pair ofrails 12 extending in a longitudinal direction on the upper surface of thebarge 10. The container cranes 30 load or unload cargo while moving in the longitudinal direction along therails 12. - Hereinafter, operating of the apparatus according to the present invention will be described.
- 1. Mooring and Anchoring the Barge at One Side of a Ship
- First, when a
container ship 70 has been moored at aquay wall 50 in a harbor, abarge 10 is tugged by a tugboat (not shown) so that amooring side 11 of thebarge 10 is disposed adjacent to a sea-side of thecontainer ship 70. Then, thepumping unit 22 is operated to fill theballast tanks 21 with seawater. As the weight of thebarge 10 increases, theballast tanks 21 sink to the bottom of the sea. When theballast tanks 21 have been seated on the bottom of the sea, thebarge 10 is firmly anchored in place. - 2. Loading and Unloading Cargo
- When the
barge 10 has been anchored in place in the manner described above, thedrawbridge 40 mounted on thebarge 10 is connected and firmly fixed to thequay wall 50. Then, cargo can be loaded or unloaded at both sides of thecontainer ship 70 simultaneously by both the cranes installed on thequay wall 50 and the cranes arranged on thebarge 10. - Then, a
trailer 80 loading cargo thereon can be driven between thebarge 10 and the quaywall 50 through thedrawbridges 40 installed before the stem and after the stern of thecontainer ship 70, to rapidly carry the cargo between them. - 3. Separation After the Cargo Handling
- When the cargo-handling has been completed, the
drawbridge 40 is separated from thequay wall 50 and retracted into thebarge 10. Then, thepumping unit 22 discharges seawater out of theballast tanks 21, thereby causing thebarge 10 to rise. - Then, the
barge 10 is tugged and moved by tugboats to another container ship or mooring site, which requires cargo handling. - 4. During Idle Time
- During idle time, the
barge 10 is moored at a quay wall or anchored at a predetermined location. When the weather is bad, for example, when it is windy, theballast tanks 21 are filled with seawater and simultaneously thecontainer cranes 30 are firmly fixed to therails 12 of thebarge 10, so that thebarge 10 can be firmly held in place against wind. - As described above, an apparatus according to the present invention can load or unload cargo at a sea-side of a container ship mooring at a quay wall, thereby enabling cargo to be loaded or unloaded simultaneously at both sides, that is, sea-side and land-side, of the container ship, more rapidly than in the prior art.
- Herein, as shown in
FIGS. 2 and 3 , a predetermined location of the seabed in front of thequay wall 50, to which thebarge 10 is seated, may be subjected to a necessary processing and a flat rock-filledbed 60 may be then formed on the location, so that theballast tanks 21 can be stably supported by the rock-filledbed 60 when theballast tanks 21 have been seated in the location. - Further, as shown in
FIG. 3 , acushioning chamber 210 may be formed under theballast tanks 21, to effectively absorb impact which may be applied to theballast tanks 21 when theballast tanks 21 are settled on the seabed while thebarge 10 is anchored. -
FIG. 4 is a detailed side view the apparatus shown inFIG. 1 , which especially shows a drawbridge of the apparatus in more detail. As shown inFIG. 4 , abridge deck 41 of thedrawbridge 40 is laid between thequay wall 50 and thebarge 10, is fixed to thebarge 10 through acoupling member 43, and is connected with adeck holder assembly 44. Thedeck holder assembly 44 is telescopically fixed to asupport tower 45 installed on thebarge 10 and thus has an adjustable length. - The
coupling member 43 installed between thebarge 10 and one end of thebridge deck 41 allows thebridge deck 41 to be pivoted up and down by thedeck holder assembly 44. Herein, a typical coupling means such as a ball joint may be employed as thecoupling member 43. - As a result, even when the
quay wall 50 is not level with thebarge 10 due to various reasons such as variances in the height of thequay wall 50 and the depth of the sea, thebridge deck 41 can be easily installed to connect thebarge 10 and thequay wall 50 with each other. - Moreover, a plurality of
roller bearings 42 disposed under the other end of thebridge deck 41 enable thebridge deck 41 to smoothly perform its original function regardless of change in the distance between thequay wall 50 and thebarge 10 due to variance in the width of eachcontainer ship 70. - Here, the
deck holder assembly 44 includes acylinder 440 and apiston 441. Thecylinder 440 is hinged to an upper portion of thesupport tower 45, and thepiston 441 is connected to the cylinder and hinged to one side surface of thebridge deck 41. Therefore, thecylinder 440 and thepiston 441 of thedeck holder assembly 44 can fold and unfold thebridge deck 41 from and into thebarge 10. When thebridge deck 41 is unfolded between thequay wall 50 and thebarge 10, thebridge deck 41 is supported between thequay wall 50 and thebarge 10. - When the
cylinder 440 is operated, thebridge deck 41 is pivoted about thecoupling member 43 to enable the height of thebridge deck 41 to be automatically adjusted. - The
support tower 45 must be firmly fixed to thebarge 10 so that thesupport tower 45 can support the weight of thebridge deck 41 while thecylinder 440 operates. To this end, awire 46 having a strong tensile strength is connected between the upper portion of thesupport tower 45 and a portion of the barge located on the side opposite to thecylinder 440. - The
bridge deck 41 has one end fixed to thebarge 10 by therotatable coupling member 43. The other end of thebridge deck 41 seated on thequay wall 50 is provided with astrut 47. - The
strut 47 can prevent wheels of vehicles passing thebridge deck 41 from being caught by a stepped portion formed due to the thickness of thebridge deck 41, thereby allowing the vehicles to pass thebridge deck 41 more rapidly and smoothly. - As can be seen from the foregoing, an apparatus according to the present invention can load or unload cargo at a sea-side of a container ship mooring at a quay wall, thereby enabling cargo to be loaded or unloaded simultaneously at both sides of the container ship by both cargo-handling apparatuses at the sea-side and the land-side. As a result, the present invention can significantly improve cargo-handling capability of a harbor in comparison with that by the prior art.
- Further, an apparatus according to the present invention can reduce the time for which a ship stays at a quay wall, thereby improving availability of the quay wall and decreasing the physical distribution cost.
- Moreover, an apparatus according to the present invention may further have a cushioning chamber disposed under each ballast tank, which can effectively absorb possible impact and prevent breakage of the ballast tanks when the ballast tanks are settled on the seabed.
- In addition, an apparatus according to the present invention has drawbridges each having length, inclination, and height, which can be freely adjusted according to the width of the container ship, the height of the quay wall, and the depth of the sea, so that the drawbridges can be rapidly installed and used regardless of the surroundings, thereby further reducing the time for which a ship stays at a quay wall.
- While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment and the drawings, but, on the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.
