Abstract

A revolving transportation device (13) capable of revolving about a center column (11) and moving vertically is provided to a cylindrical cargo hold (10, 10A) for storing bulk cargo (C). The cargo (C) from a load cargo feed port (10d) at the upper part of the cargo hold (10, 10A) is directly or indirectly handed over to the revolving transportation device (13). The revolving transportation device (13) loads the cargo (C) in a flat configuration in the cargo hold (10, 10A) while leveling out the cargo (C) in the centrifugal and circumferential directions. Deterioration in visibility and an increase in ship length due to a loading/unloading device are thereby minimized in a ship in which the cargo (C) is loaded/unloaded in a state of being leveled out in a flat configuration in the cargo hold (10, 10A) and in which pellet-shaped or granular gas hydrate cargo (C) is transported in a bulk state. This also makes it possible to reduce the size of the opening of the cargo hold and to manage the oxygen concentration and temperature in each cargo hold separately.

Then, be described with reference to the method for loading of Fig. 4 to the boats and ships 1 of the above-mentioned 1st and the 2nd embodiment, the boats and ships of 1A.

The method of loading of these boats and ships is the method for loadings of the boats and ships transported with state in bulk by the goods of the gas hydrate of granular or bullet shape, as shown in Fig. 1, Fig. 3, Fig. 4, by goods C via side, land cargo loading system 42, connecting portion 41, stretch out conveyer 23, in cargo compartment 10 that upper level conveyer 24, loading goods supply port 10d, the Clothoid type horizontal conveyance device 12a on top of cargo compartment 10, retractable chute 14, convolution conveyer 13 accommodate cylinder type, 10A.

More particularly, as shown in Fig. 4 and Fig. 9, if boats and ships 1,1A pull in shore at bulkhead wall 40, then unreactable gas is filled in the inside of stretching out conveyer 23 and upper level conveyer 24 to boats and ships 1,1A.Then, the conveyer 23 that stretches out of boats and ships 1,1A side is stretched out by telescoping mechanism or cyclotron mechanism etc., move to boats and ships 1 by connecting portion 41 and implement of freighting from side, land, side, the land cargo loading system 42 of topside of 1A is combined.After bonding, the valve at junction surface 41 is open, make side, land cargo loading system 42 and stretch out conveyer 23 and be communicated with.

And, the goods C transported from side, land cargo loading system 42 is supplied to the one end of stretching out conveyer 23 of the below being connected to connecting portion 41, the goods C this be supplied to is as shown in Fig. 3, Fig. 8, transport to one end (being the end of bow side in Fig. 3 and Fig. 8) of top horizontal conveyance device 24 by stretching out conveyer 23, goods C transports from this end side to another side by upper level conveyer 24, and to being equipped in each cargo compartment 10, each loading goods supply port 10d on top of 10A supplies.

Transported to retractable chute 14 via Clothoid type horizontal conveyance device 12a by the goods C being supplied to this loading goods supply port 10d, by freely falling, center mast 11 side to convolution conveyer 13 is transported.This goods C, by making one group of screw shaft positive rotation of convolution conveyer 13, transports from the center mast 11 side direction cylinder wall 10a side of convolution conveyer 13.

In this transport midway, goods C falls from convolution conveyer 13 and is accommodated in cargo compartment 10,10A.This is gone out, so smooth along this convolution conveyer 13 by the goods C the accommodated center mast 11 side direction cylinder wall 10a thruster of conveyer 13 from cargo compartment 10,10A of being circled round.That is, goods C is above scattered at the centrifugal direction (radiation direction) of cargo compartment 10,10A by the transport of the horizontal direction between center mast 11 and cylinder wall 10a.

In addition, if goods C is housed in this centrifugal direction one band and smooth, then make swing frame 12 circle round slightly and move in a circumferential direction, goods C is housed in its centrifugal direction one be with and smooth.This action is carried out repeatedly or continuously, if make convolution conveyer 13 circle round 360 degree, then the collecting of the goods C on this height and smooth end.That is, by the convolution of this convolution conveyer 13, by the circumferentially distribution of goods C at cargo compartment 10,10A, goods C is accommodated in cargo compartment 10,10A.

Further, if the collecting of the goods C of of cylinder type cargo compartment 10,10A week and smooth end, then the pendant line 13a that suspended on convolution conveyer 13 from swing frame 12 is rolled, make the height of convolution conveyer 13 increase specified amount.Further, if the collecting of the goods C of a week on this height and smooth end, then the height of convolution conveyer 13 is made to increase specified amount again.Repeatedly carry out this action, the just top of the collecting of goods C and the smooth bottom surface 10b from cargo compartment 10,10A is carried out, until fully laden, being carried in cargo compartment 10,10A by goods C, becoming fully laden.

By goods C to be mounted in each cargo compartment 10,10A simultaneously or to carry out successively in this cargo compartment 10,10A, make full cargo compartment 10,10A becomes fully laden.Then, by the valve (not shown) etc. being located at loading goods supply port 10d, cargo compartment 10,10A are sealed, fill unreactable gas as required.

In addition, in connecting portion 41, cargo loading system 42 side, side, land is cut off after conveyer 23 side seals respectively with stretching out and is separated.In boats and ships 1,1A side, be air by the inert gas replacement stretched out in conveyer 23 and in upper level transport value device 24.In addition, accommodate inside shipboard also fixing by reaching by reducing or circle round than the shipboard conveyer 23 that stretches out in the outer part.Thus, effect shipment.

Then, be described with reference to the discharging method of Fig. 5 to the boats and ships 1 of the above-mentioned 1st and the 2nd embodiment, the boats and ships of 1A.

The discharging method of these boats and ships is the discharging methods of the boats and ships transported with state in bulk by the goods of the gas hydrate of granular or bullet shape, as shown in Figure 1, Figure 2, Figure 5, via convolution conveyer 13, lower horizontal conveyer 21, top conveyer 22, stretch out conveyer 23, connecting portion 43, side, land emptying equipment 44, by the goods C landwards side unloading aid unloading be housed in the cargo compartment 10 of cylinder type, 10A.

More particularly, as shown in Figure 5, if boats and ships 1,1A pull in shore at bulkhead wall 40, then unreactable gas is filled in the inside of stretching out conveyer 23, top conveyer 22 and lower horizontal conveyer 21 to boats and ships 1,1A.Then, the conveyer 23 that stretches out of boats and ships 1,1A side is stretched out by telescoping mechanism or cyclotron mechanism etc., by connecting portion 43 with move to boats and ships 1 from land side dumping goods implement, side, the land emptying equipment 44 of topside of 1A is combined.After bonding, the valve at junction surface 43 is open, make side, land emptying equipment 44 and stretch out conveyer 23 and be communicated with.

Further, along with the minimizing of the goods C of cargo compartment 10,10A, the mechanism supplied in cargo compartment 10,10A by unreactable gas is adjusted.Then, is released by the pendant line 13a that suspended on convolution conveyer 13 from swing frame 12, making convolution conveyer 14 relative to the upper surface of goods C of the height being mounted in the conveyer 13 that circles round becomes the relative height obtained by experiment etc. in advance.

By making one group of screw shaft reverse rotation of convolution conveyer 13, goods C is transported from cylinder wall 10a side direction center mast 11 side of convolution conveyer 13.By this transport, goods C releases from the discharge orifice of convolution conveyer 13 to the upper surface of the circle 11c of the center mast 11 shown in Figure 11, from receiving mouth 11b to enter in center mast 11, to fall and bottom to center mast 11 is transported from peristome 11d.

Further, if this position can by the convolution conveyer 13 goods C that transport not or tail off, then make swing frame 12 circle round slightly and move in a circumferential direction, the goods C be with being in its centrifugal direction is transported to the receiving mouth 11b of center mast 11.This action repeatedly or continuously carried out, if make convolution conveyer 13 circle round 360 degree, then the goods C of this At The Height terminates to the transport of center mast 11.That is, by the convolution of this convolution conveyer 13, goods C is assembled to center mast 11.

Further, if the gathering of the goods C of of cylinder type cargo compartment 10,10A week terminates, then the pendant line 13a that suspended on convolution conveyer 13 from swing frame 12 is released, make the height reduction specified amount of convolution conveyer 13.Further, if the gathering of the goods C of of this height week terminates, then the height reduction specified amount of convolution conveyer 13 is made again.This action is carried out repeatedly, the gathering of goods C is proceeded to the just top of bottom surface 10b from the upper surface of the goods C of the fully laden of cargo compartment 10,10A, the goods C in cargo compartment 10,10A is assembled in center mast 11, becomes light condition.

Further, as shown in figures 2 and 5, by the goods C being transported to the bottom of center mast 11 by being configured in cargo compartment 10, the lower horizontal conveyer 21 of inside of double bottom 3 of below of 10A transports in the horizontal direction.The goods C transported by this lower horizontal conveyer 21 is transported in upper deck 5 by top conveyer 22, by the goods C transported by conveyer above this 22 by stretch out conveyer 23 via connecting portion 43 landwards side emptying equipment 44 transport.

By the inside from cargo compartment 10,10A of this goods C landwards side emptying equipment 44 transport, if the goods C in cargo compartment 10,10A is unloaded by whole land, then in connecting portion 41, emptying equipment 44 side, side, land is cut off after conveyer 23 side seals respectively with stretching out and is separated.In boats and ships 1,1A side, as required, the inert gas replacement by stretching out in conveyer 23, in top conveyer 22 and lower horizontal conveyer 21 is air.In addition, will reach and stretch out conveyer 23 in the outer part than shipboard and to accommodate by reducing or circle round inside shipboard and fixing.Thus, unloading is completed.

According to method of loading and the discharging method of above-mentioned boats and ships, boats and ships, due to the configuration of numerous dress emptying equipment former states, be housed in cargo compartment 10,10A, so do not need the partition loading and unloading goods in the front and back of cargo area, so hull can be made to shorten, in addition the partition height reduction of the setting of dress emptying equipment can be used in, front can be improved look into the distance, so the position of bridge can be made to reduce.Specifically, although be the stage of trial-ray method, when with 14 identical ten thousand stere design stowage of goods amount (shipload volume), compared with the boats and ships of referenced patents document 1, hinder the height reduction of enclosing partition of closing of looking into the distance to be about 3m, the length of ship also shortens about 30m.

In addition, owing to the bottom surface 10b of cargo compartment 10,10A having been made plane or having made the plane with chamber when considering draining, so compared with cargo compartment bottom being formed as cone shape or square cone-shaped of conventional art, the volume of hull can be utilized efficiently, and due to goods C is loaded to the lower position of hull, so the center of gravity step-down of hull can be made, be also beneficial in nerve.In addition, the peristome due to cargo compartment 10,10A is only the loading goods supply port 10d on top and the bottom of center mast 11, so do not need to arrange larger opening, for easily keeping the structure of airtight conditions.

Due to the loading of the motion of dress emptying equipment during handling goods in cargo compartment 10,10A and unloading both in, convolution conveyer 13 is leading role, the moving up and down of this convolution conveyer 13, centered by being controlled to of the convolution of center mast 11 and the rotation of screw shaft, so need the handling goods carried out quantitatively to control to become simple.

In addition, owing to arranging dress emptying equipment respectively to each cargo compartment 10,10A, separately goods can be loaded and unloaded at each cargo compartment 10,10A, so freight and unloading time loading turn between cargo compartment 10,10A and send not restriction on order, can make to reduce along with the increase of loading or the draft difference change of minimizing, the boats and ships 1 during handling goods, to adjust transfiguration significantly easy for the ballast of 1A.

And then, for the corresponding fields of accident when dress emptying equipment can limit fault, particularly the fault of the dress emptying equipment in cargo compartment 10,10A can be defined in this cargo compartment.Therefore, even the situation of the handling goods plant failure of a part, beyond the cargo compartment 10,10A of handling goods plant failure, also can fill emptying equipment with other goods is sent.In addition, about oxygen concentration and the temperature treatment of the dress emptying equipment in cargo compartment 10,10A, can by carrying out oxygen concentration in cargo compartment 10,10A and temperature treatment manages simultaneously.

And then, load and unload goods time, due to by smooth for goods C be plane freight, in addition, by goods C one side plane earth cut while unload, so goods C can be made not form mountain and occur vacancy, the grasp transfiguration of the carrying capacity of goods C is easy.That is, due at the end of loading and at the end of unloading, the upper surface of goods C is flattened as level, so can according to highly carrying out the confirmation easily carrying out cargo receiving amount or sendout.

And, the free breakage on the mountain of goods C is in handling goods and all do not have in shipping, so burying and fault of the dress emptying equipment brought because of free breakage can be avoided, the danger of the forfeiture of the hull nerve brought because of the goods avalanche in shipping can also be eliminated.

In addition, owing to goods can be maintained the state of planarity while load and unload goods by convolution conveyer when loading and unloading goods, so do not adopt the discharge method of the dip plane utilizing cone shape or square cone-shaped as the conventional art, so there is no the generation of the obturation of the goods C in the cone shape of conventional art or square cone-shaped, the situation can not sent because of inaccessible can be eliminated, goods C reliably can be sent.

In addition, when carrying gas hydrate as goods C, as correspondence time urgent, the tower of the central authorities of center mast 11 can be also used as discharge port when being dissolved forcibly by goods C water.In addition, needing when the decomposition water of generation is transported to manufactured place by the gas hydrate of goods C after using with consuming, cargo compartment 10,10A can be utilized as silo when being carried by this decomposition water, so the silo volume of decomposition water fully can be obtained, compared with the situation of the handling goods of employing Loading conveyer mode, the decomposition water of about 2 times can be transported to manufactured place.

In addition, the center of the cylinder of cargo compartment of the present invention is the center of circle when being at the cylinder type that above-mentioned middle illustration is such at cargo compartment 10,10A, but when shape beyond cylinder type, go out circle in the inside imagination of cargo compartment, represent the center of this imaginary circle.Further, as preferred center, when the shape of cargo compartment is the parallel each other mutually polygon cartridge type of rectangle cartridge type or opposite side, the center of intersection point as the cylinder of cargo compartment of the line at the center of each limit and opposite side will be linked.In addition, beyond it, imagination goes out and at least two place's inscribes of the wall of cartridge type, the circle of maximum gauge that do not intersect with wall, using the center of the center of this imaginary circle as the cylinder of cargo compartment.In addition, when going out multiple circle according to condition imagination, arbitrary is wherein selected, using the center of the center of the imaginary circle of this selection as the cylinder of cargo compartment.
