TransCanada Keystone pipeline leaks 795,000 litres of crude oil in South Dakota

TransCanada Corp. said its Keystone pipeline has leaked an estimated 795,000 litres of oil in Marshall County, S.D., just days before Nebraska is set to decide the fate of its Keystone XL pipeline.

The company said its crews shut down the Keystone pipeline system early this morning between Hardisty, Alta., and Cushing, Okla., and a line to Patoka, Ill., and that the line is expected to remain shut while it responds to the spill.


Nebraska regulator to announce Keystone XL permit decision on Nov. 20
The leak, which it said happened about 35 kilometres south of its Ludden pump station on a right-of-way, comes as Nebraska Public Service Commission is set to vote on the Keystone XL project on Nov. 20 to clear the last major regulatory hurdle for the $8 billion project.

Opponents of Keystone XL say the pipeline would pass through the Sandhills, an ecologically fragile region of grass-covered sand dunes, and would cross the land of farmers and ranchers who don't want it.

"Just days before the Nebraska Public Service Commissions decides on whether to approve Keystone XL we get a painful reminder of why no one wants a pipeline over their water supply," said Greenpeace campaigner Mike Hudema.

The Sierra Club was also quick to condemn the spill, urging the commission not to vote for the project.

"We've always said it's not a question of whether a pipeline will spill, but when, and today TransCanada is making our case for us," said campaign director Kelly Martin.

The pipeline would transport oilsands oil from Alberta through Montana and South Dakota to Nebraska, where it would connect with existing pipelines that feed Texas Gulf Coast refineries.

Its a conspiracy.

The environmentalists infiltrated Trans Canada, posing as pipeline operators.

They then caused a massive malfunction in order to sway the view in peoples minds of the viability of pipelines days before the pipeline was scheduled to move forward.

The initial report stated 5000 barrels.

I love how the media uses the biggest number possible for sensationalism...

Still a big leak but how many millilitres is this... I guess I'll wait for an updated news story.

Sabotage.

That's almost 1 TRILLION ml!!!! Won't someone PLEASE think of the children?

Haha exactly how my mind works instantly working in OnG. I saw the title and I'm like 795m3 is ~5000 bbls. I'm not aware of the size of the transmission line for the burst one but isn't a crazy amount. Obviously not great but yes, it is always hilarious when the media uses a unit of measurement to create the greatest reaction.

For reference purposes, Keystone moves ~591,000 barrels or about 94 million liters of oil a day.

[Sentry]

Zombie Wiebo Ludwig did it

[Redlined_8000]

800 cubes of oil.... Thats fuck all lol.

[Darell_n]

Sabotage.

Makes you wonder given the location and timing of it.

[wintonyk]

It's really unfortunate timing with the Nebraska decision on KXL to come in the next few days.

[dirtsniffer]

so 800 cubes out of the daily 94,000 cubes.

Leak detected after losing less than 1% of the daily volume. Sounds fucking great to me.

Yea I guess it depends what you classify as a lot. 5000 barrels is almost half a percent of canada’s Total daily conventional oil production. Thats a fair amount in one spill.

The worst N/A onshore oil spill in the last 25 years was only 5 to 6 times larger than this. So while it’s not overly major it’s not really something to brush off as “nothing”

Pipelines are still the most effective, safe and environmentally friendly way of transporting oil and gas IMO.

[dirtsniffer]

Less than 0.2% of what is exported daily from Canada. Keystone also ships 20% of what we export. Drop in the bucket.

[ZenOps]

Whoops.

This is the big issue here.

And also, TransCanada has been fucking AWFUL at pipeline maintenance and repairs. Their safety standards and lack of preventative maintenance is beyond reprehensible. A couple years ago the fed's did a report on TransCanada. It basically got failing grades, and the answer was for them to "self-regulate" themselves more. It's such a complete bunch of bullshit.

While we absolutely, 100% need more pipelines, that doesn't negate companies not using best practices and doing pipeline work that is actually dangerous.

Clearly, it's working out well as the leak suggests.

Anyone see the report on the pipeline in the great lakes. 42 out if 48 sites inspected failed. An oil leak there would be deveastating.

[dirtsniffer]

Nebraska approved kxl.

[phreezee]

Nice! Thx Trump!

[The Cosworth]

So sounds like a bit of work due to the alternative route, but still promising. Hope they don't use this approval against Trans Mountain.

[ExtraSlow]

Approval is one thing, actual finishing construction is another. I anticipate several years of sit-in style protests to delay this. I'd be very surprised if it was built anywhere close to the advertised timeline.

This one? The one that just passed hydro at double MOP and almost 10x the regular operating pressure stated in the article? You've been reading Greenpeace weekly.

You are using to big of words for the average green peacer.

This pipeline consultant mentioned in the article doesn't even know what he is talking about.

"Hydrotests don't really test girth welds that hold pipe segments together," he said. "They will use other records to (assess) that. It also doesn't tell you about pinhole leaks."

:confused::confused:

Didn't read the article, just your quotes.

Girth welds aren't affected by pressure the way longwelds are. But they rarely are a problem until you end up with slope instability and the pipe in longitudinal tension, or if it's under water and there is a free span under it and there is vortex induced vibration. The coatings around girth welds, however, can be a problem. As for pinhole leaks, a hold test will check for anything currently leaking. But if there is something at 95% of wall thickness, and is very short, the hydrotest won't pop it.

edit: just read the article. My statements stand. But I am no way making a statement regarding Enbridge, Line 5, or providing any assessment on the fitness for service of that line.

[g-m]

The hydro won't but the ILI will.

Weld records from construction would be evaluated and they could go do additional NDE if there were concerns. Coating repairs would be done as needed as well

No a hydro test wont pop it. Hydrotests aren't intended to be destructive testing. But a hydrotest will verify the integrity given any actual defects present. Especially one at 2 x MOP.

At any rate, my point is, these green peacer experts tend to use flashy words and spin things to make them sound big bad and dangerous when in reality, its not the whole truth.
