A bulk fluid storage container has a top wall structure and a bottom wall structure held in spaced relation by a side wall structure. An internal baffle assembly is disposed in the fluid storage volume between the side wall structure for reducing fluid sloshing. A fill port formed in the top wall structure has a fill flange for coupling with a source of the fluid. A vent port formed in the top wall structure has a pressure vacuum value. A drain port formed in the side wall structure in a lower region adjacent the gutter region has a drain valve assembly is coupled to the drain port. A frame assembly includes an upper rectangular frame member and a lower rectangular frame member arranged in spaced relation by a plurality of post; wherein the frame assembly surrounds and supports the fluid storage vessel.

Disclosed embodiments relate to devices and methods for storage and/or transport of tubular structures, such as perforating guns for use in wellbores. Some embodiments relate to modular storage containers, for example which may be height adjustable depending on the length of the tubular structure to be held therein. Some embodiments relate to mobile storage banks, which may be configured for use with the modular storage containers. In some embodiments, the storage bank may further be configured with one or more longitudinal compartments configured to hold used tool strings or portions thereof.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A tank container includes a frame having a front end opposite a rear end that defines a rear plane, a vessel extending between the front end and the rear end of the frame, and a discharge valve assembly. The discharge valve assembly comprises an internal bottom valve, an adaptor, and a discharge valve. The internal bottom valve is positioned within an interior volume of the vessel and the discharge valve is positioned entirely within the frame and offset at least one inch from the rear plane. The adaptor curves downwardly between the internal bottom valve and the discharge valve.

A dual-purpose tank container is provided, designed for transporting unrefined or refined fluid within the same internal space, eliminating unproductive deadheading. The tank container includes an inner tank in a frame, and outer insulation shell, the tank being equipped with at least one diaphragm so that a fluid, for example crude oil or diesel fuel, can occupy inner space without risk of contamination from a residual fluid. The high viscosity unrefined fluid can be almost completely drained using fluid draining channels present on the diaphragm surface, increasing transportation economy and eliminating any residual fluid pockets. At least one inlet present on the upper tank body supplies a solvent vapor/fluid to condition the space between the diaphragm and the tank wall, thereby preventing sticking of the diaphragm to the tank inner surface.

A tank rack apparatus provides a liquid storage tank. The tank includes a tank vessel having a top wall, bottom wall, side walls, and tank corners at the interface of each pair of adjacent side wall, each side wall defining a wall plane. A tank alcove provides a recess that is spaced away from a tank corner and inwardly from a tank wall plane. This inwardly spaced recess provides an alcove space having an alcove wall, an alcove top, and an alcove bottom. A sight glass gage is contained within the alcove space, below the alcove top and above the alcove bottom and inwardly of the tank wall plane. A screen occupies a position in or near the wall plane, the screen extending between a position next to alcove top and a position next to the alcove bottom.

A cargo rack for transferring loads between a marine vessel and an offshore marine platform (for example, oil and gas well drilling or production platform) provides a frame having a front, a rear, and upper and lower end portions. The lower end of the frame has a perimeter beam base, a raised floor and a pair of open-ended parallel fork tine tubes or sockets that communicate with the perimeter beam at the front and rear of the frame, preferably being structurally connected (e.g., welded) thereto. Openings in the perimeter beam base align with the forklift tine tubes or sockets. The frame includes a plurality of fixed side walls extending upwardly from the perimeter beam that include at least left and right side walls. A plurality of gates are movably mounted on the frame including a gate at least at the front and at least at the rear of the frame, each gate being movable between open and closed positions, the gates enabling a forklift to place loads on the floor by accessing either the front of the frame or the rear of the frame. Each gate can be pivotally attached to a fixed side wall. The frame has vertically extending positioning beams or lugs that segment the raised floor into a plurality of load-holding positions. Each load holding position has a plurality of positioning beams or lugs that laterally hold a load module (e.g., palletized load) in position once a load is placed on the raised floor.

A tank assembly for receiving liquids comprises a tank body. The tank body includes a tank wall defining an enclosed tank cavity. The tank body also includes a manhole lid attached to the tank wall and movable from a closed position covering a manhole in the tank body to an open position uncovering the manhole. A liner includes a flexible liner wall defining an enclosed liner cavity. An opening is formed in the liner wall to permit liquid to be introduced into the liner cavity. The liner also includes a fitting secured to the liner wall at the opening in the liner wall. A first end of a hose is attached to the fitting for conducting fluid to the liner cavity. A valve is attached to a second end of the hose. The valve and the second end of the hose are releasably attached to the manhole lid.

The invention relates to a vessel head (1) for a vessel (30), comprising: a vaulted dish area (2) having a vault radius R, a connecting contour (5) comprising in a first contour section (6) a first radius of curvature (r1) and in a second contour section (7), a second radius of curvature (r2), wherein the first radius of curvature (r1) is larger than the second radius of curvature (r2) and a knuckle area (3) surrounding the dish area (2) and tracing the connecting contour (5) is configured between the connecting contour (5) and the dish area (2) comprising, extending along the first contour section (6), a first knuckle section (10) having a first knuckle radius (r1k1) and a second knuckle section (12) having a second knuckle radius (r1k2). The invention further relates to a tool and a method of manufacturing such a vessel head (1).

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.
