The invention relates to the field of shipbuilding and concerns the creation of tanks for the carriage of liquid cargoes and liquefied gases in tanks with insulation.

Known design leak proof insulated tank built into the bearing structure of the ship's hull, consisting of blocks attached to the hull using mechanical fasteners and including primary and secondary heat-insulating panel, the primary sealing layer of metal in contact with the transported cargo, secured to the blocks by welding to the supports of the block and located between the panels of the secondary sealing layer. The blocks are interconnected using strips of sealing layers and insulating materials placed in the gaps between the blocks (United States Patent, No 5586513, WV 25/16, Dec. 24, 1996) prototype.

However, pre-made blocks that make up the tank, do not include directly into initial sealing layer, it is necessary to perform time-consuming welding sealing layer on the hull.

In addition, in the design of thermal insulation panels applied reinforcement insulating material is fiberglass, which impairs its insulating properties and increases the weight.

Mount the secondary sealing layer and a massive eploits the ion between panels is carried out using the adhesive composition, which may reduce the reliability of the construction of vertical walls and roofs capacity, especially in the case of damage to the primary sealing layer.

The task of the invention is to reduce the complexity of manufacturing and Assembly capacity in the hull while increasing reliability and improving its insulating properties.

This is achieved by known thermal insulating hermetic vessel wall for liquefied natural gas consists of secured using mechanical fasteners on the ship hull blocks, including primary and secondary insulating panel attached to the blocks of the primary sealing layer and located between the secondary sealing layer. The blocks are interconnected using strips of sealing layers and placed in the gaps between the blocks of insulating materials. According to the invention it blocks have a single subformula from all sides of the polymeric composite materials (PCM), forming a closed volume, simultaneously covering the primary and secondary insulation panel. The blocks include a primary sealing layer attached directly to the panels by stickers on the outside of subformula primary insulation panel with a partial transition to onformance secondary is teploizolyatsionnoy panel. The gaps between the panels are closed by strips of the respective sealing layer attached to the panels by their stickers on the parts of the primary sealing layer from the edges of the panels.

In addition, on the inner side of the vessel wall has a layer of PCM, navorovannye on the primary sealing layer of primary insulation panel and his band.

The primary and secondary insulation panels have individual onformance PKM from all sides, and the secondary sealing layer affixed between these subformulae primary and secondary insulation panels.

Sealing strip, closing the gaps between the panels, glued so that they are in the gaps were located below the surface of the panels 0.03 to 0.08 bandwidth within the gap of the respective sealing layer.

A thermal insulation panels as insulating material is a foam of low density or bulk materials, such as perlite.

Mechanical fasteners blocks to the hull of the vessel is a welded to the hull boss and fixed on them studs, passed through the gaps between the panels and equipped with a pressure disk and a nut.

Thus, secondary insulation panel has ledges under fasteners for us is anouki blocks to the hull.

The presence of onformance blocks on all sides of the RMB, forming a single closed volume, covering primary and secondary insulation panel, increases the reliability of the units and the vessel wall in General, and the inclusion of flexible primary sealing layer in a pre-manufactured blocks pasted on the outside of subformula primary insulation panel with the transition to onformance secondary insulation panel, significantly reduces the complexity of manufacturing and assembling the vessel wall.

Navorovannye over the primary sealing layer of primary insulation panel and the top of his bands plating layer made of polymer composite materials, for example, fiberglass, increases the impact strength of a shock when transported in containers of liquefied gas, and also acts as an additional sealing layer.

The presence of bands of sealing layers over the gaps between the blocks, labeled on the plots of the primary sealing layer, ensure its integrity.

The design of the sealing strips, closing the gaps between the panels, glued so that they are in the gaps were located below the surface of the panels 0,03-0,08 width of each band within the gap of the primary or secondary sealing layer, it is necessary to create compensationremedy and static deformations in the band corresponding sealing layer.

The single-onformance of PKM on all sides of the primary and secondary insulation panels, forming a closed structure, allows a wide range of insulating materials, including bulk, thus allowing you to improve the insulating properties of the vessel wall, as well as to reduce its mass and dimensions.

The essence of the proposed invention is illustrated by drawings, where:

- pre-made block wall which forms an insulating hermetic vessel wall made of polymer composite materials for liquefied natural gas (figure 1);

- cross section of a pre-manufactured unit (figure 2);

- cross section of a pre-manufactured unit with individual subformulae composite primary and secondary insulation panels (3);

a fragment of the cross section of the vessel wall Assembly (figure 4). We offer insulating hermetic vessel wall made of polymer composite materials for liquefied natural gas includes blocks 1 (figure 1), consisting of the primary 2 and secondary 3 insulation panel comprising a primary sealing layer 4 made of flexible material and placed between the secondary panels 5 a sealing layer and a common subformula 6 PKM on all sides of the block (figure 2, 3). As the flexible material may be the used metal foil or polymer film, for example, polyethylene terephthalate or polyimide metallized films.

Insulation Board composed of insulating material, for example foam of low density. They can have individual subformula of PKM on all sides 7, 8 (figure 3), forming a closed structure that allows it to be used as insulation material panels loose insulating materials, such as perlite. In this case, the secondary sealing layer located between the individual subformulae primary and secondary insulating panels.

Secondary insulation panel has the shape of a right parallelepiped with ledges 9 for attachment to the hull 10 (2, 4). The ledges are located approximately at half the height of the vertical wall panel and has a width sufficient to accommodate the element mounting block (figure 4).

The primary insulation panel is made in the form of a right parallelepiped and is located on the upper surface of the secondary sealing layer. The panel is smaller in terms of size compared with the secondary panel so that there is space on the secondary panel, the same from all sides for fastening strip secondary sealing layer 11 (2, 4).

The primary sealing layer block is attached to onformance with the help of glue and covers all of the upper horizontal surface of the primary insulation panel, its sides, and a horizontal platform secondary insulation Board on top of onformance, and is attached to formance using the adhesive composition. The mounting blocks to the hull (figure 4) is carried out using mechanical connections, including stud 12, a clamping disk 13 and the nut 14. To avoid the so-called thermal bridge studs are manufactured from non-metallic materials, such as plastic. The gaps between the panels are closed by strips 11, 15 both sealing layers by their stickers on the parts of the primary sealing layer from the edges of the panels.

The gap between secondary insulation panels and between the studs along the panels filled with insulating material 16, such as glass wool or foam, and the interval between the primary insulation panels adjacent blocks filled with insulating material 17 in the form of a foam or pre-engineered. The upper surface of the insulating material must form a flat surface, but may be below the level of the corresponding sealing layer of about 0.03 to 0.08 width of this layer within the gap between panels to create a thermal compensator and static deformation in the strip of adhesive sealing layer.

Manufacturer of EPS hermit who offered the vessel wall and its functioning in the transport of liquefied natural gas are as follows.

Previously factory-made units. Glue the insulation Board, put subformula unit of the RMB, which is within the primary insulation panel with the transition to the horizontal platform of the secondary panel, paste a primary sealing layer, and between the panels include a secondary sealing layer. Optionally, thermal insulation panel also cause an individual subformula of the RMB, in which the secondary sealing layer is between subformulae primary and secondary panels.

The process of manufacturing the vessel wall includes installation and fastening to the hull pre-fabricated at the factory units using mechanical fasteners. Since the inner surface of the hull has butenoate, before installing the blocks must be aligned, causing the surface of the hull rollers epoxy putty.

Previously to the hull in the planned locations are welded lugs 18 to which are attached rods (figure 4). After installing units on studs worn retaining plates, which are fixed to each stud with clamping disk and nuts.

After installation and fixing blocks the gap between the secondary insulation panels filled with insulation material, which are then closed the strips are stated secondary sealing layer. Strip with the adhesive composition are stacked on the upper surface of the secondary insulation boards on top of the covering panel of the primary sealing layer adjacent blocks. Thereby sealed the gap between the secondary insulating panels adjacent blocks and attached to the integrity of the secondary sealing layer.

Next, fill insulation material in the form of a foam or ready blocks between the primary insulation panels neighboring blocks, which are then covered with strips of the primary sealing layer by stickers with the help of glue.

Since the upper surface of fill in the gaps between the panels of insulating materials should form a smooth surface and be below the top surface of the respective sealing layer of about 0.03 to 0.08 width of its band within the gap between the panels, the width of closing the gaps between the panels, blocks, strips sealing layer is selected to meet this condition.

To ensure the integrity of the primary sealing layer sealing layers of adjacent blocks are combined. To do this, using the adhesive composition on the upper surface of the primary sealing layers of the neighboring blocks and the surface of the insulating material is material mounted band of the primary sealing layer. The width of the strips should be larger than the distance between the panels, that is, they must lie overlap on the primary sealing layers of adjacent blocks. The upshot is a continuous primary sealing layer.

At the final stage of the manufacturing capacity of its inner surface over the primary sealing layer is covered with a lining 19 of polymer composite materials such as fiberglass. This increases the impact strength of impact of the liquid carried in the tank, and also acts as an additional sealing layer.

After Assembly, the tank is filled with gas and is transported. Insulating hermetic vessel wall maintains the required temperature of the cargo, and the sealing layer prevents leakage during transport.

The proposed construction of a sealed insulating the vessel wall reduces the complexity of manufacture and Assembly capacity in the hull of the vessel and its weight while increasing reliability and improving its insulating properties, which distinguishes it from the prototype.
