we are able to calculate every thing for
them," Hosein says of the initial proposal.
"And Duke was very open to this idea,
because in the past, they had to spend lots
of money and time to drill through
concrete."
Hosein says when his company uti-
lized traditional methods in the past, the
total project length for the operator
lasted any where from six to eight weeks.
This involved the presence of an addi-
tional consulting company to assist with
the drilling work, and then about three
weeks for the actual survey—conducted
by taking readings from each individual
test point at the facility.
But when utilizing the new method,
the survey at the nuclear plant was com-
pleted within just one week in early 2017.
"We were able to map the complete
pipeline based on potentials," Hosein
explains, adding that the map enabled his
company to inform the operator of spe-
cif ic areas with suff icient protection,
poor protection, and marginal protection
in need of further monitoring. "Based on
the data, we were able to pull it off."
Looking forward, Hosein believes pos-
itive trials utilizing the factoring system
will facilitate further adoption. For
instance, he says Delta Air Lines (Atlanta,
Georgia) has already shown interest in
using the new method in the near future
at its main terminal at Hartsf ield–
Jackson Atlanta International Airport—
based largely on the complications of
drilling through the tarmac.
"In some cases, operators are reluc-
tant [to consider a new method] because
there's a certain way it's always been
done. It's just a step-by-step process with
survey consultants and contractors, and
everyone just continues to build on that
process."
"But what we're doing is kind of rein-
venting the wheel," he adds. "Because
we're going out on an island, so to speak.
This is an entirely different approach. But
at the same time, it still keeps assets safe,
and it can be very lucrative if you're sav-
ing both money and the time."
