Wikipedia cites 806 Enridge spills in a little over a decade. Sounds like really poor construction to me. I’ve been responsible for a small private water mutual for years, and we’ve had our share of breaks through the years. I we had proportionately as many breaks as Enridge, I’d be strongly looking at cheap and sloppy work from my installers. No excuse for that.
A spill doesn’t equal a break. A break is very rare.
If a worker unloading a pig (scrapper) from a receiver spills a pint of oil outside the containment, it is a reported spill.
Water spills don’t get reported like petroleum pipelines.
Enbridge has 15,294 miles of pipeline and moves more than 2.2 million barrels per day of crude oil and liquids.
How many breaks on your system would be proportional comparison?
