A trench is dug under an above ground water storage tank either before erection of the walls or after the wall is erected. A (rectangular) sump is preferably made of ? inch steel. It serves as a conduit from an inner tank liner port to an outside tank fill or drain port. The system eliminates hoses hung over the top edge of the tank wall. A pump can fill the tank from the outer port. The tank can be drained using head pressure of the water and/or a pump.

The present invention relates to a protective device (14) for a container (12) for receiving substances, in particular pulverulent substances, wherein the protective device (14) has a flexible casing (32), which encloses a casing space (38) and comprises a first casing opening (34), and a first tubular body (40) which is connected to the casing (32) in the region of the first casing opening (34) and which has a first mating container connection unit (46), a primary first end (42) and a primary second end (44), wherein the first tubular body (40) is connected to the casing (32) in such a way that the primary first end (42) terminates with the first casing opening (34) or projects into the casing space (38), and the protective device (14) can be connected to the first container connection unit (24) by means of the first mating container connection unit (46) in such a way that the casing (32) can be introduced into the interior (18). The invention further relates to a protective arrangement (10) comprising such a container and such a protective device (14).

A liner for a shipping container including one or more sections, each removably disposed in overlying relation to an interior side of the shipping container, and being formed of a thermally insulative material and including at least one breathable material segment. Each breathable material segment is at least partially formed of an air permeable material having an apertured construction structured to facilitate airflow therethrough, between inner and outer surfaces of a corresponding one of the one or more sections. The apertured construction of the one or more breathable material segments may be at least partially defined by an open mesh material or other materials which include a plurality of through holes integrally formed therein.

A folding feeder hopper includes a locking assembly and side walls, which are configured to lock themselves when unfolded or deployed for operation. The locking assembly has a first locking device provided on the side wall and configured to engage with a second locking device provided on a support assembly. The second locking device includes an elastic element and retaining members on front and rear ends of the hopper for providing alignment to the side walls when they move between locked and unlocked positions. A method for locking the side walls in a deployed position is also provided.

The present disclosure relates to multi-layered elastomer-based liners. In at least one embodiment, a coated substrate includes a substrate and a first elastomer coating disposed on the substrate. The first elastomer coating is substantially free of sulfur and includes a first elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The coated substrate includes a second elastomer coating disposed on the first coating. The second elastomer coating includes a second elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The first elastomer is the same as or different than the second elastomer and at least one of the first elastomer or the second elastomer is a polyurea-polyurethane copolymer.

A bladder having a fluid impermeable material layer that is compatible with a liquid held in the bladder and at least one impact protection layer that is conformally arranged to span a surface area of the liquid impermeable material.

A offshore system for storing oil includes a hull. The hull includes a buoyancy compartment and an oil storage compartment disposed below the buoyancy compartment. The oil storage compartment has an upper end, a lower end, and an inner cavity. In addition the system includes a water port in fluid communication with the inner cavity and configured to allow water to exit the inner cavity. Further, the system includes an oil heating and circulation system coupled to the hull. The oil heating and circulation system includes a suction line having an inlet disposed in the inner cavity proximal the upper end. The inlet is configured to draw oil from the inner cavity. The oil heating and circulation system also includes an oil heater coupled to the suction line and configured to heat oil passing through the suction line. Further, the system includes a return line coupled to the oil heater. The return line includes an outlet disposed in the inner cavity and vertically positioned between the inlet of the suction line and the water port.

A temporary bulkhead locking member comprising a unitary length of rigid material that is formed into a predetermined profile extending longitudinally along the length thereof. The profile provides first and second channels into which the leading edges of first and second bulkhead doors may removably engage with the locking member located between the door leading edges. The bulkhead doors are oriented to form an obtuse angle with each other with the angle apex pointing inward of the container when in the engaged position with the locking member.
