A heat-insulated tank with a volume of 200-20,000 m.sup.3 for storage of oil and oil products includes a heat-insulated wall, roof and bottom installed on a foundation. The wall and roof are equipped with supporting discharge skirts forming sections, the heat-insulated coating made of foam glass blocks that fill sections and form control joints in the heat insulation coating. The tank includes a top coat made of metal sheets located at an external surface of foam glass blocks. The foam glass blocks including a lower row of detachable blocks and additional rows coupled to each other and a surface of the tank via an adhesive. The technical result is improved safety and strength of the tank heat insulation at loads on its structure caused by filling and discharge of the raw material and environmental factors, and relatively even temperature control of the oil and oil products.

A container is produced from a single-layered, helically bent sheet metal strip. In the strip's upper or lower border region a first helically running border portion of the strip is bent out via a helically running outwardly bent edge with a curved region toward the outside of the container as a protruding flange. A second helically running border portion is in the lower/upper border region. The border regions each border one another adjacently height-wise and are connected to one another in a fluid-tight manner via a continuous, helically running welded joint. The second border portion runs rectilinearly in the plane of the strip and the welded joint has a first and a second weld seam. The first and second weld seams are applied from the outside and the inside of the container, respectively, and the two weld seams are fused to each other in the weld route thereof.

A cryogenic liquid tank (1) includes a reservoir (5) that includes a bottom portion (5a, 5a1, or 5a2) and a side wall (5b), a support portion (4) that supports the reservoir (5), and an intermediate member (10) that is provided between the reservoir (5) and the support portion (4). The support portion (4) includes an outer support portion (4b) which supports the side wall (5b), and an inner support portion (4a) which is disposed to be adjacent to an inner side of the outer support portion (4b), includes a heat insulating layer formed of an elastic material, and supports the bottom portion (5a, 5a1, or 5a2) of the reservoir (5). A cover portion (9a, 9a1, or 15) covering a boundary between the outer support portion (4b) and the inner support portion (4a) is provided between the support portion (4) and the intermediate member (10).

A jack for lifting segments of a structure includes a pair of masts, a mast base, a mast cap, a hydraulic ram, a bottom bracket and a shuttle. The masts are identical and upright with a plurality of evenly spaced holes. The mast base supports the mast and the mast cap receives the upper ends of the masts and maintains the masts in a parallel, relationship. The hydraulic ram moves between a retracted position and an extended position with a stroke distance which is significantly less than the mast height. The bottom bracket is removably pinned to the masts and receives and supports the lower end of the hydraulic ram. The shuttle receives the upper end of the hydraulic ram. The bottom bracket and shuttle, when not pinned to the masts, can slide vertically up the masts. The shuttle includes features for connecting to a segment of a structure.

A batten bar is configured to secure first and second adjacent flat panels to a structural framework. The batten bar includes first and second inside legs, first and second outside legs, and a plurality of apertures disposed along the length of the batten bar. The first and second inside legs define a central channel. The first outside leg and the first inside leg define a first seal recess configured to receive and retain a first seal. The second outside leg and the second inside leg define a second seal recess configured to receive and retain a second seal. In an installed configuration, the first inside leg and the first outside leg are configured to contact the first flat panel along a first common plane, and the second inside leg and second outside leg contact the second panel along a second common plane.

Embodiments of an automatic girth fitter system use a device or devices to automate the alignment of horizontal weld seams in both shop- and field-built tanks or vessels. The automated system device or devices may also be used to remove shims that are used to gap the horizontal weld seams and provide plate alignment prior to fitting or welding those seams.
