A new type of shipping container called the PASSBOX, is being marketed by Portare Systems for transporting aggregate and other sorts of bulk commodities including frac sand, grain and agricultural products, and construction materials.
The PASSBOX containers (PASSBOX stands for Portable Aggregate Supply System) have hopper-shaped containment structures with a pneumatic piping system for offloading of product. Portare said its equipment is the same size as standard 20-foot and 40-foot shipping containers and can be transported by rail, truck or vessel. It said the product has been certified by the American Bureau of Shipping.
The containers carry about 700 cubic feet, or 30 tons, of product and can be carried on standard marine chassis.
"As the U.S. and global markets continue to transport highly valuable and
potentially volatile aggregate materials such as ceramic proppant,
organic fertilizers and frac sand, companies are looking for better ways
to maintain product integrity, transportation timing and handling
efficiency," the company said.
It said PASSBOX enables aggregates to be shipped from source to
destination without transferring the materials from one container to
"Traditionally, when transportation containers are filled at the
source (silo, mine, farm, dig, pump, etc.), the contents must
eventually be trans-loaded at each exchange point (truck, rail, ship,
etc.). Now, with Portare Services’ PASSBOX, companies only need to fill
the PASSBOX once and utilize all transportation modes without ever
having to transfer the contents."
The company claims that customers save up to 30-40 percent on handling costs by
using the PASSBOX.
