The present invention comprises a surface mount secondary containment system comprising prefabricated pieces that may be assembled to form a wall and adjoining corner with overlapping sections to capture leaks, spillage or the like from a primary liquid container member that may be constructed so that no ground damage and or penetration is done during construction and use.

Systems and methods for employing a bulkhead bag in intermodal shipment of dry flowable commodities are disclosed. An example system includes a bulkhead bag configured to be positioned on a loading floor, between sidewalls, and proximate loading doors of an intermodal shipping container. The example system includes one or more straps configured to extend between and couple to connection points of the bulkhead bag and eyelets of the intermodal shipping container to hold an upper edge of the bulkhead bag aloft from the loading floor. The bulkhead bag is configured to expand when filled with a first portion of the dry flowable commodity such that end portions of the bulkhead bag engage sidewalls of the intermodal shipping container to form a partition between the loading doors and an interior of the intermodal shipping container used to contain a second larger portion of the dry flowable commodity.

A storage vessel includes a body, two or more internal chambers or sections which may hold fluids or debris, one or more bulkheads 108 within the body of the storage vessel to separate the sections, and a roll off attachment apparatus. The storage vessel also comprises a series of ports and hatches to provide access to the sections within the storage vessel. The storage vessel can be moved to and from excavation sites using the roll off attachment apparatus which allows the storage vessel to be attached to or lifted onto a truck.

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 method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes applying a polymeric concrete material to the bottom wall and side walls of each concrete section preferably using a spray application. The concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout or non-sag seal can be preferably applied to the connections.
