New technologies used to test
integrity of Bronson Lake - Paynton natural gas
TransGas is investing $9 million this
year to test the safety and integrity of its natural gas
transmission pipelines across Saskatchewan. This
includes using new technologies to test the Bronson Lake
- Paynton pipeline in a more cost-effective and
environmentally friendly manner than ever before.
The approximately month-long integrity
testing process will take place in several stages, and
will benefit communities in that immediate area.
Beginning last week, crews modified the pipeline at two
points to allow for the use of a series of in-line
inspection tools known as "pigs." Although in the past
TransGas had to vent natural gas into the atmosphere at
this stage to reduce pipeline pressure, the use of a
drawdown compressor will reduce greenhouse gas emissions
and save about $150,000 on the Bronson Lake - Paynton
testing project alone.
Flow of gas in this pipeline was
temporarily stopped on August 24 and 26 , but the
testing will not disrupt natural gas service or pose a
danger for area residents.
The next stage of testing, which begins
the week of August 30, involves inserting different pigs
into the pipeline to clean it from the inside. The pigs
will be placed into the pipeline and will travel in the
stream of natural gas for 100 kilometres before they are
received at the Paynton Compressor Station site.
During the week of September 7, TransGas
will insert a computerized in-line inspection tool into
the pipeline. While traveling through the line, this
inspection tool will measure wall thickness and detect
potential problems such as corrosion, obstructions, or
dents in the line. Once this data is collected, TransGas
will analyze it to determine if any action is required
to maintain the pipeline's safety and reliability.
"This testing is part of TransGas'
ongoing program to ensure the integrity of the
approximately 14,000 kilometres of pipeline it owns and
operates within Saskatchewan," says Daryl Posehn, Senior
Vice President of TransGas. "Scheduled maintenance on
the Bronson Lake - Paynton pipeline focuses on our top
priorities - public safety and reliable natural gas
service to our customers."
Last year TransGas invested
approximately $9 million in the safety, integrity and
reliability of its pipeline and other facilities across
the province. Only four natural gas pipeline leaks were
detected, and were repaired accordingly.
