Compact pipeline leak detection
and environmental protection
with ultrasonic pig
ACTIVE environmental protection and
prevention of income loss in pipelines
can be reliably integrated using the GLD
leak detection system.
For cost reasons, many pipelines
are only rarely inspected with smart
pigs, because shutdowns for several
inspections per year would mean huge
economic losses. Real-time monitoring
systems are a good way to detect
large leaks, but even those are often
difficult to locate. At worst, several
hundred metres (yards) of pipeline
must be uncovered and inspected – a
disproportionate effort.
To fulfil all the requirements, Gottsberg
Leak Detection has developed the GLD
202: a compact and robust leak detector,
which can be deployed easily and often.
Pipeline operation is almost unaffected
during pigging, and even the smallest
insidious leaks can be accurately
detected and located.
With this system, GLD puts control
into the hands of pipeline operators
and service providers. The world’s
only intelligent pig that – thanks to its
ATEX approval for Zone 0 – can be
used in any liquid pipeline, without
compromising operation.
The GLD 202 leak detection system
works by using multi-spectral analysis
of events, and records the noise during
the entire pipeline run every second on
128 channels. The data is suitable for
an analysis of potential leaks, and even
gives other information on the condition
of the pipeline (eg wax deposits on pipe
joints, movement of sliders). The North
German company offers a very small
inspection pig with unusual abilities,
which can be used in combination with
the GLD 30x chassis in any pipeline
with an inside diameter of 200mm
or more.
With the GLD 202, inspection of
pipelines is easy. Analysis of the data
is largely automated, so after a short
time of analysis, pipeline operators and
inspection providers reliably know the
state of the pipeline.
For the first time, such pigging
inspection can be carried out by non-
experts. This is partly because the GLD
700 analysis software, running under
Microsoft Windows, is very simple
to use.
