"The Right Way"
- Complete pipeline profile from a
point of normal cover on one bank of the
river to normal cover on the opposite
- Positive pipeline identification and
profiling of the specific pipeline desired
to be profiled. There is no assurance that
divers can provide this information
utilizing probe bars at multiple parallel
crossings in zero visibility.
- The "One Pass" system is unaffected
by river bottom currents and inspection
can be conducted generally under more
severe conditions than diver type surveys.
- Fast and reliable, field operations
are generally complete in less than 2 days
for crossings under 3000 ft.( 950m.)
Depending on clients requirements.
- Accurate plan and profile of
pipelines and cables, regardless of the
depth of cover. Depths of cover can be
determined to approximately 130 feet. The
"One Pass" system is currently the only
reliable survey method capable of
inspecting drilled crossings.
- No Pig needed. Location of
coating defects or holidays can be
- With accurate records of the pipeline
plan and profile, results of future
inspections can be compared to previous
records to ascertain:
of potential risk damage to the pipeline as
a result of bottom erosion trends which
Identification of areas where pipelines have
shifted in position due to unstable river
may to suspended pipeline spans.
accurate estimation of the cost of pipeline
- Cad (AutoCad) drawings are made
available to the client shortly after
completion of field survey work. Often
results can be drawn up overnight in
IWIS can turn around emergency inspections
with enough information in the drawings to
satisfy most client and governmental agenies
requirements within 6 hrs after field work is
complete. This is normally 2 "runs" over the
waterway and minimal QC. Full requirements and
Quality Control can then be fulfilled after the
emergency has passed.
- Drawings are tailored to the clients
needs and and requirements. The clients
title block and style is used when
- The system can be utilized from an
inflatable craft on smaller crossings.
- Air transportable, allowing
crews to provide rapid response to
