which has higher risk of frac-outs into
the surrounding rivers or fields, the
technology used by IPC, the biggest
Direct Pipe® provider in the country, is
based on a micro-tunneling machine
(AVN) which uses a slurry circuit to
pump excavated material out of the
pipeline, decreasing frac out risk.
“IPC and Direct Pipe® were selected
for the Credit River crossing because
this technology allowed for a shorter
and shallower crossing profile that
wouldn’t have been possible using
the HDD method, due to boulders and
unfavorable geotechnical conditions,”
says Jim Murphy, Engineering Consul-
tant for UPI.
Arash Jaraiedi, Project Manager of
Pipeline Projects with TransCanada
Pipelines, recalls the first National
Energy Board-sanctioned Direct Pipe®
installation in Canada. “We wanted to
makesure [thenearby landowners] felt
very comfortable and confident about
the technology. We brought forward
IPC earlier than usual, and IPC really
helped us during the design includ-
ing preplanning and pre-construction
planning for this particular project. As
a result of all this collaboration, great
