TransCanada documents obtained by a Canadian investigative program reveal that the company’s network of pipelines comprises more than 1,000 fittings that are possibly made of substandard material that is less resistant to ruptures.
In the National Energy Board’s safety notice it filed last February regarding elbows and steel fittings installed in its country’s pipelines, the board requires companies to provide a list indicating the locations of all questionable fittings.
In TransCanada’s Keystone pipeline in Canada there are more than 1,200 fittings that do not meet requirements, according to CBC News. Another 225 problematic fittings exist in the company’s natural gas network.
An NEB audit performed in 2013 in Alberta after a natural gas leak occurred on a pipeline owned by TransCanada concluded that the pipeline failure occurred in an area of the line that contained substandard materials.
Former TransCanada engineer Even Vokes had predicted that kind of accident would happen as he said he repeatedly witnessed inferior parts being installed while he worked for the company.
“The thing is, they haven’t restored the fundamental material property of toughness, which stops the cracks from growing and exploding,” Vokes said in an interview with CBC News.
The NEB is currently conducting hearings on TransCanada’s Energy East pipeline project and will submit a report on the project by March of 2018.
