Certifications: The Leaning Tree Incident
An operator recently experienced damage to their pipeline when a metal pipeline marker post was driven into the ground by a falling tree – the ‘leaning tree incident’. This is certainly not a common pipeline failure scenario. How much criticism against a risk assessment is warranted if this obscure event is missed?

A sketch and dataset details some relevant facts for each pipeline. Many, but not all, common pipeline risk issues are illustrated or implied by the data provided. Someone […]
