Assessment Continues into Incident
at Regina Compressor Station
TransGas, the pipeline transmission
subsidiary of SaskEnergy, continues to assess the cause
of a December 8, 2005 incident at its Regina Compressor
Station, involving the release, and subsequent ignition,
of high-pressure natural gas.
TransGas engineering system integrity
and design teams have been examining the pipeline
involved and initial indications are the incident was
caused by a crack near a weld in a 45° elbow pipe
fitting. This fitting is on an 8-inch high-pressure
pipeline which has been in operation for more than 30
years. TransGas will be reviewing its inspection and
maintenance criteria for similar pipe fittings
throughout its system.
TransGas has an industry leading record
of safety and reliability with respect to its system.
This is due in large part to the comprehensive system
integrity program TransGas implements each year - a
program which involves substantial investment to help
ensure the integrity of its infrastructure. TransGas
uses a variety of industry-proven technologies to assess
the structural integrity of transmission and gathering
pipelines. These technologies include computer modeling,
In-Line-Inspections and hydrostatic tests as well as
hands-on visual inspection, investigative digs, and
aerial and ground leak surveying of pipelines.
So far in 2005, TransGas has invested
$9.7 million in system integrity and improvements to its
transmission and storage infrastructure.
Once the assessment at the Regina
Compressor Site is complete, repairs will begin. The
repair work is expected to take approximately five days.
During that time the compressor station will be taken
out of service. SaskEnergy has made alternate supply
arrangements to ensure continued natural gas service to
On Thursday, December 8, 2005, at
approximately 8:50 a.m., there was an incident at the
TransGas Compressor Station southwest of Regina, which
resulted in a large flame emitting from a high-pressure
natural gas pipeline. The facility's emergency shutdown
system engaged immediately, as designed. There were no
injuries to TransGas personnel on site.
There was no loss of service to the City
of Regina or surrounding area as a result of this
