while specified feed pipe and the feed head is arranged to move relative to the specified deck for:

- storage above the deck, storage area,

and deployment overboard dragonhouse vessel in the area of deployment, when these extracted materials shall be vented overboard.

In a General sense, the invention seeks to accelerate the extraction dragonwoman materials, especially when a vessel dredging in the open sea, far from any port where dragoneyes materials may be submitted to the shore.

Specifically, considering the above disclosure or JP 201247077 or JP 2001348905, the problem to be solved is:

- improved speed of investigation of all geological allotment of the seabed,

together with the improvement of efficiency and reliability suction materials and then transportation to the barge(s) specified absorbable materials.

As a result, acceleration is zlecenia, on the one hand, and submission dragonwoman materials, on the other hand, taken into account.

For, at least, approach to solving some of these problems, we recommend the following:

- tripping means are designed to:

- towing submerged flexible suction hose and hard dragonhouse head when dragonhouse vessel moves forward and the materials are absorbed,

in addition, control tilt hard dragonhouse head, which has its first free end directed back and resting on the seabed, underwater,

Among the possible additional technical characteristics, which can be further secured relative to the above problems, it is recommended that the connection between the feed pipe and the flexible suction hose was made with the possibility of impulses throughout the intake mixture comprising water intake, be discharged overboard dragonhouse vessel specified in the barge, through the said feed head, with no tanks or bins for storage of excavated materials on dragonhouse vessel.

Moreover, the following is the method of dredging (including partial design or implementation of the constituent elements of the vessel and maneuvering them during the voyage), designed to try and resolve at least some of the above disadvantages to retrieve the loaded materials of geological allotment of the seabed and their allocation, the method includes:

from the first free end immersed dragonhouse head, which is connected with the floating dragonhouse vessel through a flexible hose made with the possibility of winding and unwinding on a rotating bobbin, located on the specified dragonhouse vessel, the absorption of a mixture of water and materials (3) through the flexible hose

- filing materials with dragonhouse vessel in one of several barges,

otlichayushiesya, that:

stage suction contains the intake of this mixture, when:

- dragonhouse ship is sailing forward on the geological allotment of the seabed,

- shipped Dragisa head and a flexible suction hose luxirous specified dragonhouse vessel (1),

- underwater slope shipped dragonhouse head is adjustable so that the specified Dragisa head has her first free end directed back and resting on the seabed, and

- flexible suction hose, which has an adjustable immersed length is specified immersed length adjusted so that the flexible suction hose is bent along it, whatever the inclination dragonhouse head,

- the submission includes the submission of these materials, when absorbed the specified mix,

when this mixture is sucked through the flexible suction hose, immediate feed intake mixture to the specified one of a number of barges 27, which floats along the side, without storing the accumulated material 3 on the specified dragonhouse vessel.

Preferably, for the same purpose, will be preferred, to:

Flexural towed flexible suction hose was changing in proportion to the specified untwisted length to suspend one of the ropes, and/or

the stage adaptation of the immersed length gibco the suction hose included the regulation of such length so when hard Dragisa head rests on the seabed and a suction side, a flexible suction hose is tensioned in the longitudinal direction.

Moreover, it is also considered to provide solutions to the above problems, the Assembly containing:

- floating dragonhouse vessel connected to at least some of the above symptoms, and

- a barge, floating along side the specified dragonhouse vessel, with the specified barge contains the boot compartment having a given volume, with the specified boot compartment open at the top and loads the specified mixture comprising water, at the top of the hole provides the ability to drain water from the feed section, when these recoverable materials, uploaded, exceed the amount that is dependent on a specified a specified amount.

Details, in particular, dragonhouse the vessel and the method further described below, together with additional features and advantages, with reference to the accompanying schematic illustration, which, without limitation:

- figure 1 shows a preferred variant implementation dragonhouse vessel discussed above, together with a symbolic illustration of a barge designed to download dragonwoman mixture,

- figure 2 is provided to the specified dragonhouse vessel, viewed from one side (arrow II),

- figure 3 shows some elements dragonhouse ship (essentially, barges), viewed from above,

- figure 4 shows an example of an overload between dragonhouse vessel and barge,

- figure 5 is a view like figure 2, on a smaller scale,

figures 6 and 8 represent two successive alternative implementation, viewed from one side (the same view as figure 2), and

- figure 7 is a top view of figure 6, together with the barge.

In figures 1, 2 shows a variant implementation of floating dragonhouse vessel 1, destined for the extraction of materials 3 3A of the water and removal of these materials overboard so to move them in a certain place.

Under the material means sand, gravel, deposits and any other substance that can be absorbed from the seabed.

Beneath the seabed means the bottom of the ocean (or sea or any water surface).

The vessel 1 has a structure 100, comprising a housing 1A, closed (rear) deck 10, which overlooks the front bridge deck 12.

On deck 10 dragonhouse vessel 1 provided with the following tools: rotary bobbin 5, on which an elongated flexible suction hose 7 is fitted on the I winding, tripping means 9 for dipping, lifting and towing of the specified suction hose, hard Dragisa head 11 located on the first end 7a of the flexible suction hose 7, for dredging material 3, the pumping means 13 connected to the suction hose to suction through him, a mixture of material and water, and a discharge node 15, which has a number of pickup heads 15b, intended for removal of the intake mixture (materials and water) over the side dragonhouse vessel, and the node 17 feed tubes located on the specified dragonhouse vessel, between the suction hose 7 and the discharge node 15, to feed intake a mixture of the suction hose in a drain node.

Hard Dragisa head 11 is an elongated structure having a longitudinal axis 11C. This design 11 is passive, which means that it is not (underwater) vehicle (such as vehicle 32, disclosed in FR-A-2919015).

This hard Dragisa head 11 has a first free end 11a, outdoor down for suction from below, when resting on the seabed 30.

Bobbin 5 is rotatable around a horizontal axis.

With the specified spool suction hose 7 can unwind under the water to drain up materials and even the whole mixture (water+materials to be removed)when the ASAS 13.

Suction hose 7, preferably, is a tube made of flexible elastic material may mechanically reinforced.

As dredging can be performed, in particular, in the open sea, and the hose 7 is wound around the bobbin 5, the length of the specified hose is greater than the length of the vessel.

For towing dragonhouse head 11 under the water from the zone of the vessel, located in front (FW) relative to the lifting means 9 (located in the rear location on the deck 10), dragonhouse vessel further comprises a towing means 21. The figure 2 shows that the towing means 21/21A, preferably, will be held between the front part 10 a housing 1A and dragonhouse head 11.

And lifting means 9, and a bobbin 5 will be placed on the deck so that the flexible suction hose 7, together with dragonhouse head 11, is adapted to move between:

- the first non-working position above the deck, on the side 10A, adjacent to the first side 100a of the housing, and

the second working position, in the water, by descent to the side and down along the specified first side 100a of the housing.

The first lateral side 100a may be a starboard or port side.

For a more simple move the flexible Assembly sucking the th hose/Dragisa the cylinder axis 5A reel 5, around which it is rotated for winding the specified flexible suction hose is preferably essentially parallel to the axis 1A of the roll of the ship.

For the overall stability of the vessel accommodation axis 5A parallel to the specified axis 1A of the roll should be an important decision (see figure 1).

As also shown in figure 2, the towing means, preferably, contain a cable 21A having an adjustable length between the vessel (1A) and dragonhouse head 11, for underwater control dragonhouse head when a specified vessel floats.

The reel or drum 22A is connected with a drive (winch) means 22b to enable regulation of the length of the towing means, depending on water depth, denoted by L in figure 2.

If, as recommended, and shows the Assembly 7/11 is deployed along side 100a of the casing, the drum 22A, preferably, will be located next to the specified side 10A/100a front. Drive means 22b, preferably, will be managed with the bridge deck 12, located near the nose of the ship.

The location of the drum 22A on the front deck 100 located at a higher level than the bottom of the rear deck 10 will be preferred: if there would be any problem, it would be faster and safe is it solved, moreover, since the regulation of the length of the towing means can be very important.

Front deck 100 is located next to the bridge deck 12 and in front of it.

As shown in figure 1, node 17 feed tubes, secured to the deck 10, preferably, contains rigid pipe 17A fixedly attached to the deck dragonhouse vessel, above, for transmission to the intake of the mixture of the flexible hose 7 on the discharge node 15.

To increase the speed and efficiency of the dredging operation on the figures 3, 4 shows that the discharge node 15 preferably includes a rigid pipe 15A connected to the first end a with node 17 of the feeding tube and the second end 151b with feed cylinder 15b.

As shown, specified feed cylinder 15b passes transversely relative to the tube 15A and made with the possibility of placing overboard dragonhouse vessel.

In these illustrations the discharge pipe 15A and the feed head 15b are cross-sectional, and these heads are parallel relative to the longitudinal axis as the vessel and the adjacent barges (see figure 1) so that the corresponding elongated passage is provided for the materials.

As shown in figure 1, the number of parallel discharge tubes/heads 15A/15b will be provided along the second side 100b of the casing 1A (see also figure 4).

From the above description, and f is the Gur can be understood, what a flexible hose 7 with hard dragonhouse head 11 and the pump 13 is made with the possibility of lowering and lifting on one side of the vessel (left side or right side), 100a in the illustrations.

With this purpose, the lifting means 9 provided with cables 26 and, preferably, connected to dragonhouse head 11 located on the side 10A of the deck 10.

The cables 26 to suspend one form ropes made with the possibility of twisting and untwisting and United as hard dragonhouse head 11, and the controller 110 length to suspend one of the ropes.

A controller 110 length to suspend one of the ropes, preferably, will contain a winch, which will be connected to suspend one of the ropes 26, together with sensors and/or other devices for measuring length, connected to a compute node.

Through such a controller 110 length to suspend one of the ropes tripping means 9 adapted to:

- towing submerged flexible suction hose 7 and the hard dragonhouse head 11, when dragonhouse vessel 1 is moved forward and the materials are absorbed,

in addition, control tilt And hard dragonhouse head, which has its first free end 11a, directed backward (BW) and resting on the seabed 30, under water.

The vessel is additionally provided with re what Ostrom 120 length of suction hose to control the length of the flexible suction hose, unwinding from the reel 5.

This controller is very similar to the controller 110 length to suspend one of the ropes, as both are designed to control, and if you want regulation, the length of the structure, which can nakativaetsa/to blur or twist in/out. As a consequence, may be used that is identical to the above.

Moreover, the vessel is also provided on Board with the main controller 130 length connected with the controller 120 of the length of the flexible suction hose and regulator 110 length to suspend one of the ropes.

The main controller 130 length is a main controller provided to regulate, in accordance with one another, the unwound length of the flexible suction hose 7 and untwisted length (at least one) to suspend one of the ropes 26, so that the flexible suction hose is bent along the length L1, whatever the inclination And hard dragonhouse head (see figures 1, 6, 8), when (while) dragonhouse vessel moves forward (FW) and the materials (namely the whole mixture) are absorbed through the hose 7.

As shown, L1 represents the length of the hose along its axis 11a, between the hard dragonhouse head (compound 7a) and sea surface 300, in place 7b, where the specified hose 7 is in the water (see figures 5, 6, 8).

As a consequence, L2 (direct the linear length between hard dragonhouse head and sea surface 300) in this case, less than L1. Similarly, untwisted length of cables 26a, 26b is smaller than L1, when absorption occurs.

The curvature may vary depending on the speed of the forward stroke of the vessel and the resistance of the water.

Moreover, the rest of the length, is wound around the bobbin 5, and/or the rest of the twisted length, at least one of the specified suspend one of the ropes 26 can be used instead of the corresponding unwound and untwisted lengths.

This main controller 130 length, or the main controller includes a computing device that is connected to both of the above computing device controller 120 length flexible suction hose and regulator 110 length to suspend one of the ropes.

The starting point (zero) may be the appropriate length, untwisted, when Dragisa head 11 is located on deck 10 (see figure 1, solid line).

The device 140 for measuring, located on Board, is intended to measure or calculate the depth of water between the sea surface 300 and the seabed 30 or distance, such as the vertical distance D (figure 8), between the sea floor (front dragonhouse head, in front) and the vessel.

Can be used by the sensor 150, such as "echo".

If used, the device 140 to measure, probably including the sensor 150, preferably, the connection is with the appropriate regulators 110, 120, 130 lengths (at least the connection to the main controller 130 length).

In accordance with the information registered by the device 140 to measure the corresponding controllers 110, 120, 130 can operate separately or together to control the corresponding length under control.

This solution prevents impact on the hose 7 flexible execution and operation of suction, if the level of the seabed changes and/or too big waves.

It should be understood that these unwound/wound and unwound/twisted length of each will be measured or calculated relative to the given initial length.

To prevent excessive sensitivity of the feeding head to disturbances and waves in the open sea, and a discharge node 15 is arranged to move, that is, turning on the figures, relative to the specified dragonhouse vessel, in order to have his discharge head:

- stored on deck 10, in the zone SZ; figure 3,

and deployed overboard dragonhouse vessel in the deployment zone (DZ figure 3), when the intake mixture is challenged overboard.

In this embodiment, this/each specified axis is parallel to the axis 1A. The axis of rotation of the discharge of the node 15 is the position 23a, 23b on the figure 3.

Specifically, it is preferred that asany discharge site was made with the possibility of rotation relative to the deck dragonhouse ship around the first and second horizontal axis, accordingly, 23a, 23b, for rotation between a storage position and a deployed position, and to move up and down his/each feed head 15b.

As a result, the discharge node can be moved up and down around a horizontal axis.

This solution is effective to limit the space allocated for the specified discharge site, on the deck. Especially, it provides the possibility of a preferred store outlet node, in a vertical position in an unusable state (see figures 1, 3 dark continuous line).

Each pipe 15A, preferably, will contain at least first and second elongated (tubular) portion, respectively a, 153b, United articulated in the intermediate zone of the tube, around a horizontal axis 23b. Moreover, the first elongated portion a, preferably, will have a swivel at the lower end 155, where it is connected to the deck 10 (horizontal axis 23a, figure 1).

As a consequence of the above and figures 1-3 can be understood that, in an unusable state, the specified first and second elongated part a, 153b are composed essentially vertically, with the axis 23b above and behind and discharge head 15b below (behind), whereas in working condition (dotted lines in figures 1, 3) so-called first and second elongated parts expand what you (ripped) forward (more or less horizontally with the horizontal axis 23a behind and discharge head 15b front, over barge 27, which represents a motorized barge; preferably towed or self-propelled barge.

From the point of view of the improved suction, pumping means 13 contains dragonhouse pump 13A, located next to dragonhouse head 11, so that the specified dragonhouse pump submerged when Dragisa head dragonet materials (see figure 2).

To ensure the exact location of the vessel in the area of dredging dragonhouse vessel 1 preferably will be provided with one or more onboard propeller drive means 25, managed to bridge deck 12, to move the ship.

More specifically, these side propeller drive means, preferably, will be designed for location dragonhouse vessel dredging material 3 from the zone 30 dredging (such as the seabed) and the suction of the mixture.

Therefore, dragonhouse vessel will not have any means of fastening on the riverbed, fastening means on the seabed, the anchor means to the river channel and anchor means for the seabed (such as traditional anchors)that are designed to temporarily hold dragonhouse vessel when dragonauts materials and absorbed the mixture.

As a consequence, the vessel in this case will be a "free-floating" bark is eh.

Figure 4, a floating barge 27 is adapted for positioning along dragonhouse vessel 1 (see also figure 1).

As mentioned above and shown in figures 1, 4, this barge 27 will be located along the specified second side 100b of the hull front (lower) discharge of node 15, elongated in its deployed position.

The specified floating barge 27 is a floating node, which is made with the possibility of moving and storing materials. She has a body 26, 28 of the deck and feed section 29, which may be located a cylinder 15b outlet node, overboard dragonhouse vessel for removal of the intake mixture specified in the boot Department.

The boot compartment 29 is open at the top.

Moreover, the following(s) system(s) improve(s) the applicability of the solution according to the invention for feeding a mixture overboard dragonhouse vessel 1 above the specified boot compartment 29 for deposits.

Moreover, if the vessel 1 is a free-floating ship, is preferred to the site 27 was a powered barge. This barge will be driven by a tug or self-propelled barges.

In particular, with the aim of reliability overload intake mixture from the vessel 1 to the node 21, when the excitement and/or waves are high, so the solution will provide the ability to build the specified vessel and node swim, essentially, side by side (side 100A of the vessel 1). Is it possible not to use smartaudio means for detachable connection with each other dragonhouse vessel and the floating barge, when the specified mix shall be removed from dragonhouse ship to the node 27.

Specifically, servo positioning system can manage the relevant provisions of the Board by Board dragonhouse vessel and floating barges, one relative to another.

For this device control the speed and course as a mining ship and barges can be synchronized by means of respective drive means 25, 272 connected to the rudders 250, 274 of the vessel 1 and node 27, respectively (see figure 1). Running appropriate(for them) sailor/sailors to control the tiller such funds would support both vessels 1, 27 within a predetermined distance range (transverse and longitudinal) during the dredging operations and/or overload.

These rudders and tiller, located on the bridge, in a General sense, ask control means adapted to control the vessel 1.

Alternatively, the electronic system 33 positioning can be installed on the vessel 1 for dynamic management of the relevant provisions of the Board by Board specified vessel and the floating barge 27, one relative to another, when Viseu amanuta the mixture shall be removed from the vessel to the node 27. System 33 positioning and drive means 25 in this case would be connected to each other. Preferably, the node 27 will also be provided with coordinated electronic means 34 positioning, United wireless image system 33 positioning and adapted to control the motor 272 and the wheel 274.

In any case, smartaudio funds and/or pneumatic means can be used between the vessel 1 and barge 27.

During overload the head 15b of the discharge site will be located in the so-called zone DZ deployment (figure 1) and, preferably, will have its horizontal(s) and/or vertical(s) position(I), adaptable(s) as a function of the degree of loading of sediments node 27 together with the relevant provisions on Board of the vessel 1 and the floating barge 27, one relative to another.

To increase the speed and efficiency of loading barges 27 intake mixture is preferred to feed section 29 was opened on the top of the level 28 of the deck was made with the ability to freely interact with the outside, so the water released intake mixture will gradually merge overboard, as this mixture is gradually loaded in the boot compartment 29.

Preferably, the floating barge 27 not even Boo the em to have any closing means, intended for closing the boot compartment 29 (see figure 4).

Moreover, to increase the speed of operation of the exhaust suction materials when the node 27 is filled with materials, and water was removed from the mixture, filed in the specified compartment 29, a floating barge 27 may be a drop-down barge, adapted for loading with an open top and drain through the bottom of the chassis (see zone 32 in figure 4, where the movable sash can be located at the bottom of the compartment 29, as part of the body).

From the above description it is obvious that the use of barges 27 having an open top feed section 29, together with the above-mentioned discharge node 15 will provide the ability to load barges extracted with a mixture comprising water, at the top of the hole provides the ability to drain water from the feed section, when (while) recoverable materials 3, uploaded, exceed the amount that is dependent on a specified amount of feed section 29.

It is also clear that the connection between such (each) supply pipe 15A and the flexible suction hose 7, preferably, is arranged to urge the entire intake mixture comprising water intake, be discharged overboard dragonhouse vessel, barge 27, through-feed(s) head(s) 15b, without the and tanks neither hopper nor branch (such as the Department of 29) for storing at dragonhouse vessel excavated materials 3, suction through the hose.

From figures 1, 6, 8 will be further noted that, preferably:

- tripping means 9 will contain the front and rear lifts 9a, 9b provided with respective front and rear to suspend one of the ropes 26a, 26b,

- bobbin (5) will be located on deck 10:

or between the front and rear lifts,

- front or front lift 9a,

and the flexible suction hose 7 is connected on the side, topped with hard dragonhouse head 11, 13:

any angle relative to the axis 11a hard dragonhouse head,

or, passing in front, along the direction parallel relative to the specified axis 11C hard dragonhouse head (see figure 5).

Figure 8, the angle, in essence, is a right angle, although it represents an oblique angle in figure 6, to allow connection of the hose 7, passing from above and behind (BW), with hard dragonhouse head 11.

Figure 2, on which the bobbin 5 is located in front of the front lift 9a, the flexible suction hose 7, passing in front (FW) and the top is connected with the specified hard dragonhouse head 11, 13 along the direction parallel relation to the so-called axis 11a as the rigid dragonhouse head.

In the three illustrated embodiments, implementation, both forward and rear to suspend one of the ropes 26a, 26b is attached to the rigid dragonhouse head 11, 13 to regulate the specified slope A.

This solution improves the efficiency of control tilt And, as it can be adjusted forward and backward.

Considering now the so-called method of dredging, which can occur with all or part of the above means, it is designed to retrieve submerged materials 3 of geological allotment 30 of the seabed and drains into the barge, preferably, immediately.

Because it is still useful to provide additional information, this method contains:

from the first free end immersed dragonhouse head 11 the absorption of a mixture of water and materials 3 through the flexible hose 7,

- filing materials with dragonhouse vessel in one of a number of barges 27,

- at this stage suction contains:

- the absorption of the above-mentioned mixture, thus:

- dragonhouse ship is sailing forward on the geological outlet 30 of the seabed,

- shipped Dragisa head 11 and a flexible suction hose luxirous dragonhouse ship,

- underwater slope And shipped dragonhouse head is adjustable so that the specified Dragisa head has her first free end 11a directed the Azad (BW) and resting on the seabed 30, and

- flexible suction hose has its submerged length adjusted so that the flexible suction hose 7 is bent along it, whatever the specified slope and

- the above submission of materials to the barge contains a supply of these materials, when the mixture is sucked through the towed suction hose.

Moreover, as described above:

- bending of the hose 1, preferably, will vary in proportion promoted (or twisted) length to suspend one of the ropes 26, 26a, 26b, and

- the above submission will contain, when a mixture of materials + water is sucked through the flexible suction hose, immediate feed intake mixture to the specified one of a number of barges, which floats along the side, without storing the accumulated material 3 in the vessel 1.

From the point of view of additional protection flexible suction hose from damage due to excessive voltage, it is assumed that the stage adaptation of the immersed length of the flexible suction hose contains the regulation of such length so that when the hard Dragisa head rests on the seabed 30 and the mixture is absorbed, the flexible suction hose 7 is tensioned in the longitudinal direction, namely, in essence, not stretched in the longitudinal direction (tension exerted by the waves, water and MSE of the awn stroke, excluded).

Similarly, it is recommended that:

with free-floating mining vehicle 1 is a so-called mixture of water and materials 3/3A absorbed pumping node 13 is preferably submerged pumping node 13A through the flexible suction hose 7, when the vehicle 1 is floating on a geological challenge,

- the intake mixture immediately served with a mining ship in one of a number of free-floating barges 27, which swim alongside the ship.

Preferably:

during these operations specified a lot of empty barges from a number of will swim around the mining vehicle 1 (see figure 4),

and when this one free-floating barge, such as 27, which floats along the side of the mining ship, full of absorbable materials, one empty barge, such as 27A, will replace the full barge as soon as possible.

As a consequence, it is recommended that the above stage suction mixture of water and sediment 3/3A, together with the stage of submission of the intake mixture through the discharge/feed node 15/15b - was carried out at the same time.

If the vessel 1 is not self-propelled vessel, it will be pushing or dragging pushing or pulling tug (preferred option implementation).

Even if dragonhouse vessel is specially adapted for dredging in the open sea, it can also used the change in any water, including rivers, lakes....
