Today, guest scientist Andrew Boyd discusses The Box. The University
of Houston presents this series about the machines that make our civilization
run, and the people whose ingenuity created them.
When the converted oil tanker Ideal-X arrived in
the Port of Houston on May 1, 1956, no one imagined the global change it foreshadowed.
Longshoremen stopped work and ran to the edge of the dock to watch. So did businessmen
who had flown from the port of origin in Newark, New Jersey. One witness said,
"We had seen thousands of tankers in Houston, but never one like this. So everybody looked at this monstrosity and they couldn't believe their eyes."
But it wasn't the ship itself that captured the onlookers' attention. It was the
many metal boxes strapped to the deck, each roughly the size of a truck trailer.
In his book The Box, Marc Levinson tells the history of those unpretentious
crates. "What is it about the container that is so im-portant?" writes Levinson,
"Surely not the thing itself. A soulless aluminum or steel box held together with
welds and rivets, with a wooden floor and two enormous doors on one end: the standard
container has all the romance of a tin can." In fact, engineers find much to admire.
From the design of the corner-posts to the stacking brackets, shipping containers
display the finest elements of "here's-a-problem-let's-solve-it" engineering.
But the true marvel of the shipping container was how it changed the engineering of the
world economy. Before 1956, packages were loaded by hand. As a result, ships spent
weeks in port -- far more time than they spent at sea. Today, huge cranes unload a
standard shipping container and return to retrieve another in under two minutes,
allowing huge vessels to dock and sail in less than a day. When the Ideal-X
first sailed, the cost of loading loose cargo was six dollars a ton. That plummeted
to a mere 16 cents with the use of shipping containers.
Great as these savings were, we didn't feel the full impact of container shipping until
it spread throughout the supply chain. Trucks and trains were quick to adopt standardized
containers. Even manufacturers embraced shipping practices that capitalized on the economies
of working "within the box." Industrial engineers and operations researchers stepped up
with insightful new mathematics to take full advantage of the efficiencies created by
containerization. In less than 50 years -- practically overnight for such a capital-intensive
enterprise -- transportation and manufacturing were completely re-engineered.
Great ports that failed to see the coming change disappeared, while others grew to
international prominence. Singapore, one of the world's smallest countries and the
world's largest container-port, hosted 148 cargo ships per day in 2005, moving the
equivalent of 23 million, 20-foot containers during the year. With thousands upon
thousands of containers in port at any given time, a drive along the waterfront is a
spectacle as impressive as a shuttle launch.
Shipping containers are now part of our daily lives. We pass them on highways -- count
them as they go by at train crossings. They're the bits and bytes of an international
trade network they created. And the true genius they represent is less the box itself
than it is the genius of catching an idea whose time has come.

work.
