The present disclosure relates to a soil completely-covered tank system with a built-in valve chamber. The valve chamber includes a spherical tank body, a valve chamber, and a channel; an exterior of the spherical tank body is completely covered with soil, and the spherical tank body is supported by a stand column and is arranged on the ground, such that a gap is formed between the bottom of the spherical tank body and a ground foundation; the valve chamber is arranged between the spherical tank body and the ground foundation; a top opening of the valve chamber is connected to the bottom of the spherical tank body by means of a first connecting structure.

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.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

An equipment dry bay is provided. The equipment dry bay includes at least one partition that subdivides the equipment dry bay into a plurality of compartments, wherein the at least one partition includes a plate, and at least one flame arrestor positioned within the plate and providing vapor and fluid communication between a first compartment and a second compartment of the plurality of compartments, the at least one flame arrestor configured to vent combustion gases in the first compartment into the second compartment.

An Internet of things (IoT) based system for deploying volatile corrosion inhibitor (VCI) in order to mitigate soil-side corrosion of an aboveground storage tank is provided. The system includes: a VCI tank for storing the VCI; corrosion detection sensors on a soil side of the storage tank for detecting the soil-side corrosion, generating corresponding detection signals, and transmitting the detection signals over the Internet; a control circuit including control logic for receiving the detection signals, generating a flow control signal, and transmitting the flow control signal over the Internet; and a flow control valve (FCV) for receiving the flow control signal and controlling a flow of the VCI from the VCI tank to the soil side of the storage tank in response to the flow control signal in order to mitigate the soil-side corrosion of the storage tank.

A tank fill adapter device for a portable fluid tank provides a connection between an inlet collar of a tank and a supply pipe for filling the tank with a fluid that introduces an air gap into the connection. An annular mounting flange mounts against the inlet collar using a fastened connection. A pipe supporting portion protrudes upwardly from the annular mounting flange for supporting an open end of the supply pipe spaced above the inlet collar. An outer annular baffle protrudes downwardly from the annular mounting flange for being received into the tank through the inlet collar and an inner annular baffle is supported within the outer annular baffle to define a generally annular space between the outer and inner annular baffles which remains in open communication at a bottom end thereof with an interior of the tank.
