A system and methodology facilitates the handling of oilfield material. The oilfield material is stored in at least one silo which enables use of gravity to feed the oilfield material to a blender or other suitable equipment. Each modular silo is transportable and may be engaged with a support structure via a pivot connection. Once engaged, the silo is pivoted to a raised, upright position on the support structure. The oilfield material is then moved to an interior of the silo, and gravity may be used to feed the oilfield material to a blender or other equipment in a controlled manner.

Improved equipment bases and methods for making and using same are disclosed herein. The equipment base can include a first coated substrate including a first part having a first thickness sized to provide the load-bearing support for the equipment, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness sized to provide the load-bearing support for the equipment, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the bottom of the equipment.

Provided is a base plate unit, which is of an integrated structure made of fiber reinforced polymer-matrix composite and comprises a base plate unit body and foot plates. The base plate unit body comprises at least one bearing part, each bearing part comprising a panel, a plurality of web plates extending downwards from the bottom of the panel, and bottom supports disposed at the lower end of the web plates. The web plates comprise two side-web plates on the two sides of the panel and a middle web plate in the middle. The foot plates are disposed on the two outer sides of the bottom of the base plate unit body, and are formed by the bottoms of the two side-web plates on the outmost side of the base plate unit body respectively extending outwards horizontally. Also provided is a base plate unit provided with a cavity filling member.

A barrel is capable of vacuum loading and unloading, gravity unloading and loading, and pneumatic unloading. A roll-off skid is coupled to the barrel.

Structural modules for layout of modular power plants are disclosed. The structural modules comprise a substation module and a power house module, basically formed by platforms having stringers and crossbars designed for the mounting of containment sheets. Both modules include interconnections including, for example, projecting tabs for the mechanical mounting of fixation elements enabling the connection between the modules and the mounting of columns, crossbars and lifting frame so as to form a structural skeleton suitable to contain the canopies, hinged doors and sliding doors and other mechanical structures making up the spatial areas designed for the installation of various equipment, such as a group of generators, fuel tanks and tanks for containment of liquids, motors, busbars. The substation module forms a support base whose stringers and crossbars are lined with containment sheets which, in turn, are secured by welds.

A container made of plastic material, provided with a body and a bottom extending at a lower end of the body, the bottom including an annular seat extending substantially in the prolongation of the body and defining a seating plane; a concave arch that extends from a zone near the seat to a central zone, the arch including a series of stiffeners that extend radially from the central zone to the seat.

A floor assembly for a trailer includes stringers that extend in a transverse direction of the assembly and are spaced from one another in a longitudinal direction of the assembly. The stringers are made of a thermally insulative first material. A bottom flange is coupled to a lower portion of a respective stringer. A top flange made of a second material is coupled to an upper portion of a respective stringer. Floor panels are also provided. Each floor panel extends in the longitudinal direction, is supported by the top flange, is coupled to another floor panel along respective edges thereof, and has at least one rib that extends in the longitudinal direction and depends substantially perpendicularly from a bottom surface thereof. Each floor panel is made of the second material and each at least one rib is welded to a top surface of the top flange.
