Under the category of things that are very nearly disasters, I am surprised that there actually are not more accidents. At the end of my career at TransCanada, with the self-inspected welders, when I was told what they were doing, the exact same practices that we were doing in 2011, we were doing in the 1970s, and it resulted in a pipeline rupture in 1992.
Vers la fin de ma carrière au sein de TransCanada, on m'a parlé des pratiques d'auto-inspection des soudeurs; ces pratiques étaient les mêmes en 2011 que dans les années 1970, et elles avaient donné lieu à un bris de pipeline en 1992.
