A portable storage container that is constructed so as to provide a first technique and a second technique to access the interior volume. The portable storage container of the present invention includes a base platform having a housing that is superposed the base platform and operable to be removed therefrom. The base platform includes apertures that are configured to align with mounting pins of the housing. The base platform includes wheel assemblies that are configured to assist in movement of the assembled portable storage container. A pair of lifting members are secured to the top of the housing and are configured to operably engage with forklift tongues so as to provide removal of the housing from the base platform. A door is provided on one end of the housing wherein the door provides an alternate technique to access the interior volume in addition to the lifting of the housing.

A floating roof system with lightning protection includes a storage tank and a floating roof disposed inside the storage tank. A shoe seal is installed in sealing contact with an inner side wall surface of the storage tank. A primary seal extends between a rim of the floating roof and the shoe seal. A secondary seal extends over the primary seal and has an end in sealing contact with the inner side wall surface of the storage tank. Several shunts are distributed along a perimeter of the floating roof. The shunts extend over the primary seal and under the secondary seal. The shunts are attached to the primary seal and shoe seal by connections distributed along the shoe seal. The shunts are also attached to the primary seal, the secondary seal, and the rim of the floating roof by connections distributed along the rim.

A lightweight flame-resistant composite panel is provided including a body portion and a side portion folded over the body portion. The side portion includes a channel segment adjacent to the body portion, and an overlapping segment adjacent to the channel segment. One or more panel apertures are located in the body portion and the channel segment for receiving bolts through the side of the panel. An edge reinforcement insert can be inserted underneath the channel segment in a channel defined by the folded side portion along an edge of the body portion. The edge reinforcement insert includes one or more insert apertures for receiving the one or more bolts through the panel, thereby increasing the bolt bearing strength of the panel along its edge. The edge reinforcement insert may comprise an elongated strip, a plurality of separated tabs, or an end cap, or may alternatively be contained within the panel.

A soil completely-covered structure includes a base layer, slope body filling soil and a buffering layer; the base layer is arranged around a vertical tank body and is made of a base material located on a ground floor, and a first filling gap is formed between the base layer and an outer wall of the vertical tank body; the slope body filling soil is arranged on the base layer, a second filling gap is formed between the side of the slope body filling soil and the outer wall of the vertical tank body, and a side slope surface is formed on the outer side of the slope body filling soil; and the buffering layer is formed in the first filling gap and the second filling gap, and the buffering material fills the first filling gap and the second filling gap to wrap the surface of the vertical tank body.

The injector assembly device disclosed herein provides a rapid and inexpensive way to seal leaks in bolted tanks, without having to drain the tank. Leaks occur over time either between the overlapping tank panels, around the tank bolts or a combination of both. It is a very costly and time-consuming process to drain tanks in order to repair such leaks. The device disclosed can therefore find application specifically in field of bolted tanks, but also in numerous different applications when a water tight seal is required between two pieces of material that are bolted together.
