Transporting oil and gas by pipeline in Canada 4.5 times safer thant by rail

Transporting oil and gas by rail in Canada is a lot more risky than moving it by pipeline, concludes a new study by the Fraser Institute.

Utilizing newly compiled data from Canada’s Transportation Safety Board (TSB) and Transport Canada, the study, Safety in the Transportation of Oil and Gas: Pipelines or Rail?, finds that the rate of occurrences (incidents or accidents) per million barrels of oil transported is more than 4.5 times higher for rail than it is for pipelines for the period 2003-2013.

“Federally regulated pipelines in Canada currently move just under 15 times more hydrocarbons than do the railroads. But with increased production and continued opposition to new pipeline infrastructure, more and more oil is being pushed to rail – a mode of transport which is more likely to experience a spill,” said study lead author Kenneth P. Green, Fraser Institute senior director of natural resources studies.

Between 2003 and 2013 — because of larger transport volumes — pipelines did experience more occurrences compared to rail (1,226 versus 296). But, according to the TSB, the vast majority (99 percent) of those incidents or accidents did not damage the environment.

Specifically, 73 percent of pipeline occurrences resulted in spills of less than 1m3 while 16 percent didn’t cause any spill whatsoever.

More importantly, most occurrences (83 percent) didn’t happen in transit, they happened in facilities (ie: compressor stations, processing plants and terminals) which are more likely to have secondary containment mechanisms and procedures.

The study also references the mounting literature about the pipeline safety in the United States. Established research in that country suggests that moving oil by non-pipeline means (rail or truck) is linked to a greater likelihood of spills and injury to oil transport workers.
