Keystone pipeline operator says faulty welding and other problems led to the Kansas oil spill

Canadian oil company TC Energy said Thursday that faulty welding caused an “instantaneous rupture” in its Keystone pipeline that gushed hundreds of thousands of gallons of extra sticky tar sands crude oil onto Kansas native prairie, cropland and into a creek.
Meanwhile, the pipeline operator now estimates less oil escaped than originally thought. And it revealed that it expects the cleanup and investigation will cost about $480 million.
Investigation into the spill
The federal government required TC Energy to have a third party conduct metallurgy tests. TC Energy says it can’t make the full report public. The Kansas News Service has filed an open records request to the federal government seeking the full document.
TC Energy gets three months to complete an analysis of the cause of the spill. That report must be “supplemented or facilitated by” a third party. The analysis isn’t finished, but TC Energy said in an online post early Thursday that the mechanical and metallurgy results had come back.
It says those tests point to factors including “bending stress on the pipe and a weld flaw.”

Yes they are, when you consider the millions of barrels that have been pumped versus the millions of miles of railroad traffic from tank cars. Same thing, flying a commercial jet is way safer than driving your car. Yes, occasionally we have crashes from major aircraft and people die by the hundreds but if you think of the millions of people who've flown, the deaths per thousand miles or per million miles is way less. Statistics is something that someone like President Biden doesn't believe in. Many Democrats don't believe in economics and finance and just like recently, they think that if you raise taxes on the top 1% who already pay over 40%, that's going to show equity. But if you have a Democrat who actually takes Finance like President Clinton and JFK had, they know that lowering taxes raises revenue. So you got to put it in the proper perspective because a leftist Democrat versus a moderate Democrat will understand the math.

Welding mistakes happen as well. I'm sure many submarines had defective welds and I'm sure that they had to redo them and people lost their lives because welders didn't do their jobs.
There is inherent risk in everything we do in life.

President Biden is an idiot. He wants to kill the oil and gas industry even though he claims it should live for another decade. He adds rules and regulations, slow walks permits after getting leases and begs our enemies to pump oil for us instead. Case in point :Venezuela.
Venezuela is the new not in my backyard partial oil source for our oil deficit. It is a socialist Utopia that Bernie Sanders bragged about years ago but now this country is in total chaos and even President Biden is giving special consideration to venezuelans. Venezuela is a communist country with a parliament that has no power. My cousin shook the hand of Hugo Chavez when he was for the OAS until 2005. Maduro and Chavez were protected by Cuban secret service. You have Iranian and Russian operatives in that country. Venezuela has the worst environmental stewardship ever imagined.

So this is our president and this is how he leads from behind and caters to our enemies.

Maduro’s government is squeezing what it can from the collapsing industry — andunleashing an environmental disaster in the process.

My cousin was the Honduran representative to the organization of American States from about 2001 to 2005. He was also the deputy in ambassador in Washington DC and in Ottawa for Honduras until 2016. My voice text did not make it very clear

Cars and Airplanes are regarded as safe forms of travel. Accidents do happen.
"The nation's more than 2.6 million miles of pipelines safely deliver trillions of cubic feet of natural gas and hundreds of billions of ton/miles of liquid petroleum products each year. They are essential: the volumes of energy products they move are well beyond the capacity of other forms of transportation. Nov 6, 2018" -https://www.phmsa.dot.gov/faqs/general-pipeline-faqs

..."Investigation into the spill
The federal government required TC Energy to have a third party conduct metallurgy tests. TC Energy says it can’t make the full report public. The Kansas News Service has filed an open records request to the federal government seeking the full document.
TC Energy gets three months to complete an analysis of the cause of the spill. That report must be “supplemented or facilitated by” a third party. The analysis isn’t finished, but TC Energy said in an online post early Thursday that the mechanical and metallurgy results had come back.
It says those tests point to factors including “bending stress on the pipe and a weld flaw.”
TC Energy seemed to point a finger outside its own ranks, saying the weld flaw was made at a “fabrication facility.”
“The weld flaw led to a crack that propagated over time as a result of bending stress fatigue, eventually leading to an instantaneous rupture,” TC Energy wrote in its press release. “The cause of the bending stress remains under investigation.”
The company said welding inspection and testing had complied with “applicable codes and standards.”
It also said the pipe itself showed no defects.
And it said the Keystone was operating at a legal pressure level when it burst.
The Kansas News Service submitted an open records request in December for a report that shows the precise pressure levels at the time of the rupture.
In late December, the federal government allowed TC Energy to restart the pipeline, on the condition that it operate for the time being at a lower pressure than when the rupture occurred.
“Our focus continues to be the safe operation of the pipeline system,” TC Energy wrote in its press release.
The federal government is also requiring TC Energy to look for other potential weak points within the 96-mile stretch of the Keystone system that includes the site of the spill in Washington County near the Nebraska border.
That stretch runs from Jefferson County in Nebraska through Washington, Clay and Dickinson counties in Kansas."...
