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 its customers.
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 incident.
