Also, in 1970 Northern Natural Gas had a $133-million project
for 730 miles of line to bring gas supplies in from Canada.
Columbia Gas System, El Paso Natural Gas and Transco each had
projects in excess of $110 million pending before regulators.
The magazine's April 1971 issue described rebuilding of
the Grand Canyon's water system pipeline - required after a
disastrous 1967 ﬂood - which was tagged as the most diﬃcult
project ever. One of the original contractors, Elling Halvorsen,
of Seattle, had broken his back during that calamity and also
lost his equipment and working capital. But he was determined
to return and did so.
Explorer Pipeline, a vital 1,400-mile link for reﬁned products
supply from the Gulf Coast to the Midwest was completed and
began operating in 1972.
In 1973, El Paso Natural Gas had a number of huge projects
on the boards. The magazine also reported the completion of
United Gas' $59-million Sea Robin System expansion - the
furthest extension from the shoreline of any project and the
ﬁrst use of 36-inch pipe in the Gulf of Mexico.
Huge gas pipeline projects from Alaska were planned in 1977,
such as the 731-mile, 48-inch Northwest Alaska Pipeline, but
sat in limbo waiting for a ﬁnal ruling on decontrol of prices.

The industry now dealt with the Federal Energy Regulatory
Commission (FERC) instead of the Federal Power Commission.
More than $12 billion in new projects, many of them
big-inch, were anticipated in 1978, with a number of them
being oﬀshoots of the Alaskan line in transporting that oil
to Lower 48 destinations.
The LOOP (Louisiana Oﬀshore Oil Port) project, at an
estimated $260 million, also began that year in the Gulf of
Mexico and would be the ﬁrst U.S. deep water port capable of
unloading supertankers - a terminal that literally brought the
pipeline system to the vessel.
One result of the 1979 energy crisis was a huge volume of
new jobs in the Mideast. Other countries, including Mexico,
Argentina and Brazil, sought to cash in on the virtual windfall.
Plans called for 30,000 miles of construction at an estimated
cost of $13.7 billion.

Emerging technologies
Technology innovations made increasingly complex projects of
the 1970s possible - and successful - by allowing increases in
safety, environmental; performance, reliability and eﬃciency.
The coatings realm, for example, saw the development

Experience a new way to Cure
ONESTEP resin system from Interplastic Corporation is
designed to be a simpler, safer process for initiating a
Cured-in-Place Pipe (CIPP) resin. The ONESTEP system is
available with several different resin formulations, both neat
and enhanced.
