A system for transporting fluid cargo within a shipping container, the system comprising an open topped box having side walls and end walls and a flexible membrane which either independently or in combination with the box contains the fluid cargo. The box supports the portion of the cargo within the box and is designed to flex and absorb at least part of the horizontal forces generated within the cargo during its transportation thus preventing overloading of the walls of the surrounding container. The membrane may be a bladder which completely encloses the cargo and is disposed partially within the box to contain the cargo independently of the box. The box may have a floor pan which can seal the box against leakage of any cargo.

The invention relates to a thermally insulated transport container with a housing for forming a space for goods, with walls and a thermal insulation abutting the walls as well as a wall structure of such a container. In particular, the invention relates to such a container as an air cargo container. According to the invention, sandwich plastic plates are provided as walls, with a honeycomb core welded on both sides to one covering ply, respectively, the honeycomb core and the covering plies consisting of a thermoplastic material, preferably PP. In this case, the walls are, in particular, a thermoplastic sandwich panel, consisting substantially of a PP (polypropylene) honeycomb core and PP covering layers, in particular glass-fiber reinforced, which are, with regard to the materials, homogenously connected to each other by thermally fused connection. Such plates are offered, for example, by Wihag Composites GmbH & Co. KG under the trademark MonoPan®, which are preferred in this case. The use of thermoplastic material makes it possible for adjacent sandwich plastic plates to be attached to each other by welding, particularly in the region of the edges. In particular, it is thus possible to produce largely frameless and thus lighter transport containers.

A modular subsea fluid storage unit comprises a variable-volume inner tank having a rigid top panel and a peripheral wall that is flexible by virtue of concertina formations. The peripheral wall is extensible and retractable vertically while the horizontal width of the tank remains substantially unchanged. A side wall of a lower housing part surrounds and is spaced horizontally from the peripheral wall of the inner tank to define a floodable gap between the peripheral wall and the side wall that surrounds the tank. An upper housing part extends over and is vertically spaced from the top panel of the inner tank and overlaps the side wall to enclose the inner tank. The floodable gap and the upper housing part enhance thermal insulation and trap any fluids that may leak from the inner tank.

In an oil storage tank having an interior oil storage chamber and a tank opening in one of the boundary walls, a heating assembly is supported to extend into the interior oil storage chamber from the tank opening. The assembly includes a casing of walls surrounding with a casing mounting flange mountable in sealing engagement relative to a tank mounting flange about the full perimeter of the tank opening such that the casing protrudes into the interior oil storage chamber of the oil storage tank. The heating chamber is suitable sized and configured to operably receive a catalytic heater therein. The heating chamber further accommodates entry of combustion air and combustion fuel into the heating chamber and exhaust of emissions therefrom.

A refrigerated cargo container includes a cargo container and a refrigeration unit. A plurality of refrigerant tubes are in fluid communication with the refrigeration unit and extend along a roof of the cargo container. The plurality of refrigeration tubes are configured to convey refrigerant there through and cool an interior of the cargo container via natural convection and thermal radiation. A method of cooling a cargo in a cargo container includes flowing a refrigerant through a plurality of refrigerant tubes disposed at a roof of the cargo container. Thermal energy is transferred from container air in the container to the refrigerant thereby cooling the container air. The container air is circulated via natural convection toward the cargo thereby cooling the cargo via thermal energy transfer to the container air. The container air is recirculated toward the plurality of refrigerant tubes.

A container refrigeration device aims to prevent low temperature damage to freight in a container. The container refrigeration device includes: a temperature controlling section (101) configured to perform, in a switchable manner, first temperature control under which a temperature inside the container (C) is controlled based on a blown air temperature (Tss) and second temperature control under which the temperature inside the container (C) is controlled based on a suction air temperature (Trs) during dehumidification operation; and a control switching section (103) configured to switch the first temperature control to the second temperature control when the blown air temperature (Tss) is higher than the suction air temperature (Trs) during the dehumidification operation in which part of a refrigerant discharged from a compressor (30) is allowed to flow into a reheat heat exchanger (83).

Vessel assemblies, heat transfer units for prefabricated vessels, and methods for heat transfer prefabricated vessel are provided. A heat transfer unit includes a central rod, and a plurality of peripheral rods surrounding the central rod and connected to the central rod. The plurality of peripheral rods are movable between a first collapsed position and a second bowed position, wherein in the second bowed position a midpoint of each of the plurality of peripheral rods is spaced from the central rod relative to in the first position. The heat transfer unit further includes a heat transfer element connected to one of the plurality of peripheral rods.

This invention is directed toward a self-contained heated portable vacuum slurry box which is manufactured from steel rated for cold temperatures. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay containing a power unit, and a tailgate, a The invention herein utilizes a selection of steel that allows for a vacuum slurry box to function in the cold environmental conditions.
