Fig. 1 describes the viewgraph of cross-section of a ship tank, is designed for and stores cold liquid, and such as liquid natural fuels, the tank of such ship contains outer wall, and it is anchored in the load larrying member of a ship.Especially, the load larrying member in this situation are made up of a catamaran of inside, and the wall of inner casing is represented by label 1.
On each wall of load larrying member, the wall of a relevant tank is all by the second barrier layer 2.Second sealing barrier 3, first barrier layer 4, and a continuous superposition support of the first sealing barrier 5.Anchorage on the thermal insulation element of the second barrier layer on the wall of load larrying member be by thermal insulation element in the cooperation of thru-bolt and inner edge realized by the cooperation of an adaptor union with thermal insulation element or other available forms.
First barrier layer 4 and the second barrier layer are made up of thermal insulation element, discharge side by side according to normal mode.Especially thermal insulation element is the sleeve pipe of the form with a parallelpiped.First thermal insulation element and second thermal insulation element define one with the barrier layer of roughly even curface, which support the first sealing barrier 5 and the second sealing barrier 3.
The structure of the structure of ship, especially catamaran, is made up of large-sized prefabricated component blocks 6.Prefabricated component blocks 6 can form pipeline and the equipment of a part.Such as, in FIG, load larrying member are just provided with four prefabricated component blocks 6. further, and tank includes a large chamfering 60 and little chamfering 61. 1 doube bridge blocks 7 and a double-basis block 8 and is assembled on end 9, and forms with two lateral mass 10.The end of doube bridge block 7 is the mid points being adapted to chamfering 60, and the end of double-basis block 8 is the mid points being suitable for low chamfering 60.Fence, is equivalent to the element in load larrying member, the tank of two vicinities in this element separate hull.Be made up of a prefabricated component blocks equally, this precast construction block is connected to by doube bridge block 7.Double-basis block 8, and the periphery that the side direction block shown in a Fig. 1 is formed.Each precast construction block 6, all contain a large amount of little blocks 11, all each assembling forms prefabricated component blocks 6.
Before mutual assembling precast construction block 6, the tank skin of part can on block 6 pre-reinforcement, for this purpose, before assembling block 6, tank skin assembly 12 is installed on the inwall 1 of block 6 on a dry platform, forms hull.Being arranged on of tank skin assembly 12 block makes it may promote at plane domain or on harbour, such as workshop, the manufacture of adiabatic and sealing barrier.In addition, pre-reinforcement block 6 may reduce assembling sealing and thermally insulated tank generation tank in the use amount of scaffold.
But tank skin assembly can not extend to the end 9 of block 6, assembles with this, especially with welding, the end 9 of block 6 is installed on another block.Therefore, after being equipped with block, the sealing layer of adjacent prefabricated component blocks and the assembling of adiabatic layer are arranged at adjacent contiguous block 12 by adiabatic Connection Element and realize, and, be welded on a mode sealed on sealing layer 3 and 5 by inserting adiabatic layer attaching parts 14.Therefore prefabricated component blocks can reduce taking of deck equally, therefore now only has join domain to need to install.
Before assembly 12 pre-installation to block 6, the second sealing barrier 3 on assembly needs to be mounted to form a sealed volume with load larrying member, is then the fluid sealability of test sealed volume.First sealing barrier 5 is mounted for formation second sealed volume subsequently, and its fluid sealability is tested subsequently.By such mode, the fluid sealability of the tank skin assembly 12 of each block, can be tested before the installation of block 6.Therefore, each piece is independent test, makes it within the test duration, efficiently and economically go hydraulic pressure to bear test, thus controls the risk that also to there is fluid sealability when tank completes installation and do not pass a test.In addition, can go to verify the fluid sealability independently belonging to the sealing barrier 3 and 5 of assembly 12, there is the situation of leaking at the second sealing barrier 3 does not need to remove main layer assembly 5 yet.
Usually, assembly 12 can be connected by the mode of a junctional membrane.Fluid sealability on join domain 13 can be therefore tested, therefore, can be identified before assembly 12.
But, in order to realize internal gas between the first barrier layer and the second barrier layer circulation, have opening between the sealed volume of the first barrier layer of adjacent block, between the sealed volume of the second barrier layer of adjacent block, be also provided with opening equally.
Fig. 2-Figure 10 illustrates the step of the method for a production tank skin assembly 12, occurs in the 11-11 of region, is assembled on assembly 12 by the mode of attaching parts.
Can see in Figure 10, the first sealing barrier 5 in Fig. 1 and the second sealing barrier 3 are the forms with metallic film, be made up of, be arranged at the welding strong point of prolongation, supported equally by iron and steel the invar base plate 15 being parallel to crimping.Further, the welding strong point be arranged on barrier layer 2 and 4 is retained on each shell of barrier layer 2 and 4 lower surface.Such as, the welding strong point is arranged on a group groove with T-shaped, covers on the thermal insulation under casing cover plate above barrier layer 2 and 4.The crimping 18 of base plate 15 is welded on the welding strong point.A sealing barrier contains this base plate with crimping, and this can be described on file FR2798358.
The first sealing barrier 5 on assembly 12 and the second sealing barrier 3 are produced and check the step of hydraulic pressure, in hull structure prefabricated component blocks 6, be show in Fig. 2 and Fig. 5.
In fact, edge time Fig. 2 illustrates the assembling of assembly 12 on second sealing barrier 3.For this purpose, the under casing 16 relevant with assembly 12 is protected by the bearing wall 1 of block 8, and each under casing comprises an overplate, and this is processed into by clamping plate, does not mark in figure.The plate of 1 millimeter is made by invar, and has edge under casing to cover dull and stereotyped 16 protections, such as, goes to the edge extending assembly 12, therefore forms one and put down too.Invar base plate 15 is welded on the welding strong point.Be welded on platform panel 17 after invar 15.Invar base plate 15 and the thick second partition 20 of 0.7mm be installed to assembly 12 platform below, perpendicular to bearing wall 1.Dividing plate 20 has a wing 21, has extended in parallel the second sealing barrier 3, and in the below of this layer.
A welder 22 with roller turner bite makes it to be connected on second partition 20.Can see in Fig. 2 that welder 22 contains a track 23, be installed on the high limit of of framework 24.Framework 24 has been installed to bearing wall 1, is to contain magnetic bolt 26 by telescopic leg 25, and he is connected on bearing wall 1.A Welder with skid wheel can along track 23, and by taking turns 27 to realize rolling, this can by the edge supports of track 23.In addition, track 23 contains a gear tooth, can match with track 27.This track 27 has tooth, and can allow comes back along driving loads and unloads.Welder 41, with a roller turner bite, has a U-shaped structure, wherein has the extendible portion of a platform 17.Roller turner bite 29 is the ends being arranged on U-shaped structure.Therefore two skid wheels 29 can be applied and be separated by the plate of sealing barrier 3, and the wing 21 of second partition is separated by plate 17.Two skid wheels 29 are electric welding rod, ensure the smooth welding of the wing 21 of plate 17.Allow Welder 41 by track 23 along overtime work welding.Therefore, welding gear 22, with skid wheel, makes the tight weld of minimizing between plate 17 and dividing plate 20.
Fig. 3 illustrates the step that provides fluid sealability between second partition 20 and bearing wall 1.For this purpose, an angle bar 19 is welded on second partition 20 and bearing wall 1 by with the form of a sealing.This welding is actually to have been come by a fireworks carrier 30 as one kind, and he instead of very Welder 41, with a roller turner bite on track 23.Two fireworks carriers 31 extend out from carrier 30 as one kind, length the same as angle bar 19, in order between each comfortable angle bar 19 and load larrying member 1, on angle bar 19 and dividing plate 20, create a welding bead.Two welding flames 31 between, carrier 30 as one kind forms an arm 94 equally, and it is retained in its end, on carrier 30 as one kind, allows arm 94 to have freedom to a certain extent, in a directive property plane of track 23 by axle 95. axle 95.At another end, arm 94 is for being positioned at bearing wall 1 and second partition 20 by angle bar 19, and this is also for making the distance that between angle bar 19 and welding flame 31, maintenance one is constant.This behavior is used for making the quantity of welding to reduce.Pressure in order to the pressure roller 96 reducing arm 94 exceeds the scope of angle bar 19, and wall 94 contains a spring jack, does not mark in figure.Pressure roll 96 has a kind of form being applicable to not joining with carrier 30 as one kind, and is suitable for being connected with angle bar 19, and is suitable for acute angle 93.The wheel of roller outside can form an angle of 90 degrees, or less angle, guarantees the pressure between angle bar 19 and bearing wall 1 with this, in addition, also can ensure the pressure between itself and separator of battery plates 20.
Between a circulation 33, mark in the diagram, be welded on equally on angle bar 19, and in the mode in a hole through the latter.Between between following, 33 are made up of the rectangular angular of a side, and it is under casing 16 opening, but is blocked by the limit 34 of under casing, stops it to fall under casing, can be at welding gear.33 composition one supports 35 equally between following badly, it is supported on above bearing wall 1.In the diagram, between circulation, 33 is be not labeled on section-drawing, but he is illustrated on section-drawing in fig .9.The area of the hole that circulator 33 is formed on angle bar is 100*30mm, one circulation between 33 can every 20 meters arrange one.
When the welding of boundary plates 17 and angle bar 19 is implemented in the rectification periphery of the assembly 12 of the second sealing layer, bearing wall 1, second partition 20 and sealing barrier 3 define second sealed volume 32.A hole through the second sealing barrier 3 enters sealed volume 32 for injecting natural fuels, creates extra pressure with this.Therefore.Any may cause the mistake of welding of leaking can be assembled at the first sealing barrier 5 and the first barrier layer 4 before examined out.
Fluid sealability tests in second space by creating overpressure, detects gas effusion particularly in the welding of metallic membrane or the angle bar 19 of fillet weld and boundary plates 20.It carries out the gas of excessive pressure in the first space or second space can be helium.A kind of for detecting helium device, it is such as undertaken by the geometric configuration of robot sealing barrier subsequently, then carries out along the welding of the pre-reinforcement of tank skin building-blocks 12, to detect any leakage.As modification, such as, also can at the cavity nitrogen injection of assembly 12, to detect its reflection under overpressure.
When sealed volume 32 is detected without any leakage, main barrier layer 4 and the first sealing barrier 5 can be installed on the second sealing barrier 3, after closing the hole for test liquid of annotating.Therefore, the thermal insulation element of the first barrier layer 4 is positioned on described second sealing barrier 3, and is fixed on bearing wall 1.As can be seen in the diagram, dropped into installation again at primary seal baffle plate 5, be arranged on the device of main thermal insulation element, and with the mode of a sealing be fixed on main boundary plates 37 (by
the problem manufactured), on main edge caisson 36.
Vertical main separator of battery plates 38 is put between the first sealing barrier 5 and the second sealing barrier 3.Main separation 38 is made up of the thick constant steel of 0.7mm, extends to time sealing barrier from primary seal barrier.
In each boundary plates 17 and 37, main separator of battery plates 38 comprises a wing 39 and 40 and extends in parallel corresponding edge limiting plate 17 or 37.Therefore, be similar to the welding described by Fig. 2, the wing 39 and 40 can weld by with the mode of welding machine 41 roller turner bite.Particularly, can be undertaken by welder 22 described in Fig. 2 in the welding of secondary side limiting plate 17 upper limb 40.But load onto sealing barrier 5 and make to occur slight displacement between second partition 20 and main separator of battery plates 38, the weld seam of the wing 40 and 21 does not superpose.Therefore, the weld seam of two separator of battery platess 20 and 38 is independently.
Boundary plates 37 upper limb 39 welding this part embody in the diagram.In order to this welding, framework 24 is replaced by higher framework 44, and it has the function of welding machine 41, and roller turner bite keeps similar.Similar with second-circulation housing 33, major cycle housing 42, embodies in fig. 8, is welded on main separator of battery plates 38, and through this main separator of battery plates 38.Circulation housing 42 is closed in its end 43, and end is positioned at the pre-outside strengthening the subassembly 12 of block 6.Circulation housing 42 is welded on the top of separator of battery plates 38.
When being that both wings 39 and 40 establish fluid sealability along the overall profile of tank skin parts 12, as shown in Figure 5, whole profile along tank skin parts 12 creates, as represented at Fig. 5, the main volume 45 demarcated by the first sealing barrier 5 and the second sealing barrier 3 and main separator of battery plates 38 can be tested the mode of the second volume 32 to be similar to.
Double-basis block 8 right 1 and other block 6 fit together.Embody in figure 6 for two piece 100 and 101.Block 100 and 101, with secondary insulation barrier 106, secondary seal barrier 107, first major insulation barrier 108 and primary seal barrier 109 are welded 103 by by bearing wall.When Fig. 6 assembles in an embodiment, block 100 comprises ground 112, and this guarantees to be combined by its bearing wall soldering group.Such as, in Fig. 6, block 100 comprises keelson 112, guarantees the connection between floor as intensifier.Floor 113 in block 101 in the space of catamaran hull as the main horizontal stiffening device of hull bottom.Block 101 also comprises and holds dividing plate 114, is called as the intermediate tank axle in cofferdam.
Joint between bearing wall 103 between block 100 and 101 leaves the space 110 of size 111, to allow this welding operation.In welding operation, contingent is that double-basis wall 103 may be out of shape in region 104.The distortion on double-basis wall 103 surface may cause the difference of surface evenness 105.The difference 105 of surface evenness can produce the edge along weld seam.After welding operation, can the difference of measured surface degree of uniformity, such as tens millimeters.
When block is assembled, the connection between the assembly 12 of body of wall enhancing part in advance can be carried out at join domain 13, particularly by the mode of the connecting panel 45 of sealing barrier 3 and 5.
In order to this object, be first necessary to install insulated case.But the use of difference 105 to calibration caisson asks a question.
In order to address this problem, with reference to Fig. 7, use the prefabricated box 115 that thickness reduces.These prefabricated boxes 115 are placed on the layer of the low of double-basis wall or hollow part formation by stiffener 117, to guarantee to support compensation plate 116.Stiffener 117 is typical fluoropolymer resin reinforcing materials.This compensation plate can be made up of timber or high density polyurethane foam, is generally the foam density of 200 kilograms/cubic meter.Therefore, the connection of stiffener 117 and compensation plate 116 makes to regain the surface evenness of support and the difference in thickness between the box 115 reducing thickness and the insulation caisson being contained on block 100 and 101 in advance.Once the continuity of secondary insulating barrier is guaranteed, the continuity of necessary guarantee time a secondary fluid sealing, then increase main screen barrier.
Such Connection Step, existing with reference to the accompanying drawings 8 to 10.
Thermal insulation element 46 and 47 is placed and puts in place on the insulating barrier of the secondary dividing element of two adjacent subassemblies 12.Particularly, a frame caisson 47 is positioned in below boundary plates 17, and fills the space between border and abutment wall 1.Then caisson 46 in the middle of also comes on border caisson 47.In fig. 8, secondary cycle housing 33 is indicated in cross-sectional plane, and therefore it can find out the inner space of the shell that to be connected with container.The border caisson 47 of shell and volume 32 and middle caisson 46 each comprise groove 48 and 49 on the lower surface thereof, its receives circulation housing 33.In addition, this central caisson 46 is included in a vertical channel 50 outside it, extends above lower groove 48.Therefore, vertical channel is formed from circulation housing 33 to the funnel of caisson 46 upper surface.
Base plate plate with crimping is connected on Second Edge limiting plate 17 by welding bead.The adjacent tank wall components that this operation corresponds to lateral mass 10 carries out, to form the second connection space 51.Then, the air-tightness of the second connection space 51 is checked by the connection mode 52 provided in groove 50 aperture plate, and then gas inject is to the second connection space, to identify any leakage, is similar to the aforementioned method detecting leakage.
In order to provide the connection between the different shells 32 and 51 separated by the second dividing element 20, circulation housing 33 is bored a hole by the cutoff port 99 shown in Fig. 9, this perforation by connect 52 and groove 50 then pierce through this instrument inserted by connection 52 and groove 50 and carry out being connected 52.Then the device of upwards being closed down stopper by is stopped.The fluid occurred in second housing 51 and 32 is in this way as can circulate at multiple continuous rack in fig .9 indicated by arrow 98.
