Corrosion Warnings at BP Facilities in Alaska: Here’s What the Data Mean
Following up on our earlier reporting, we explain what it means that 148 of BP’s pipelines in Alaska have been ranked for “failure” by BP inspectors, according to documents we received from BP workers.

ProPublica reported on Tuesday that 148 of BP's pipelines in Alaska had been ranked for "failure" by BP inspectors, according to documents obtained from BP workers and now published online. Here's a little more detail on what that means and a more robust explanation from BP.
According to a BP report generated on Oct. 1, 2010, 351 isolated locations on 148 unique sections of pipes or pipelines have been given an "F" ranking and are deemed at risk of failing. That includes larger outdoor oil and gas lines as well as smaller waste pipes and indoor drain lines, but all of them can transport hazardous or flammable material. The F-ranks are based on hot-spots -- corroded locations along the line that can range from less than an inch to a couple of feet in size -- and may be worn as thin as a few thousandths of an inch.
It doesn't take much to cause a spill. When BP's oil transit line -- which was not "F-ranked" -- spilled 212,000 gallons of oil onto the snow in 2006, the largest spill on Alaska's North Slope, it was found to have seeped through a corroded hole less than half an inch wide.
According to the BP data, some pipelines have many locations worn thin enough to warrant the rating. One waste line for produced water has 42 locations at risk of wearing through.
When such a location is identified, it is given the "F" ranking, the most severe rating in the company's routine maintenance program and an indication that more than 80 percent of the thickness of the pipe in question has corroded.
"It means the pipe wall is corroded to the point where it has to be retired," said Martin Anderson, a former pipeline inspection supervisor for a BP contractor. An F-rank can also be occasionally assigned based on problems besides corrosion, like a dented or cut pipe, he said.
BP told ProPublica that the F-rankings indicate the company's monitoring is working well -- the inspectors are identifying trouble spots so that BP can fix them and prevent a spill. The company emphasized that it maintains over 1600 miles of pipelines, and it is not unusual to have 148 lines listed. It said there are always "F" ranks working through the system.
"To our knowledge, we've never had a line with a F-rank defect fail in service," said BP Alaska's spokesman, Steve Rinehart.
Rinehart said that as of Nov. 3 the company had 61 pipelines with 151 hot spots "F-ranked." The data is different from ProPublica's, he said, because it relates specifically to the pipeline systems extending from the well pads through the production system, and may not include smaller lines that are ancillary to the process. Of the 151 F-rankings that he described, 15 are on out-of-service pipelines, 17 are on pipelines where the flow or pressure has been reduced, 104 are on operating pipelines with scheduled repairs and 15 have already been repaired or resolved.
But workers like Marc Kovac, the BP employee who provided the data to ProPublica, allege that the company has not been quick enough in addressing problems. Instead, said Kovac, many of the pipelines have been allowed to languish with temporary patches or postponed repairs.
The F-rank data obtained by ProPublica lists inspection dates for when the rankings were assigned and shows that many of the lines' problems date back to 2008 and 2009. A smaller number of lines were inspected in 2005. One is dated 1994.
"An item can be an F-rank and can stay that way for some period of time as long as the situation is stabilized," said Rinehart, who says a pipe can be patched, shut down, or de-rated to handle less material. "It's a big job and we're all over it.”
"BP has not responded properly over the years and allowed the problems to pile up," Kovac said. "It's a joke in the field to say 'this is a temporary permanent patch.' We know the patch will be in place for many years."
ProPublica has posted the "F-rank" corrosion data here. The document consists of data Kovac copied from its original form into this sheet, in order to protect the identity of the worker who first ran the report. ProPublica verified the data against photographs of the original print-outs, and shared a sample of the data with BP prior to our initial story about the F-ranks on Nov. 2.

Good reporting. Real danger that will not play big in the dailies. Failure of the pipe and disaster, now that’s a story!

This article is such a joke! Does anyone out there really believe that the equipment you put into service to do work - is intended to last forever? Do your automobile tires ever need replacing? Do you measure them and make a judgement on when to replace? Do you think Budwiser, Pilsbury, Coke, Pepsi, Mary Kay, Carghill, Weyerhaeuser, any nuclear power plant on the face of the earth, or all other industries that use piping to convey liquids and solids do not have inpsection criterion for their equipment? Do you think they rank them for replacement? I do!
Give me a break will ya! Your just trying to sell you article by making it doomsday!
Also, please tell me how a mechanic working for BP can be an expert and tell you how an engineered piping repair plan could be deemed too long or how a temporary “patch,” as the article says, it not capable of out performing the base material. Get someone that has the skills needed to help you determine if running the piping systems on the North Slope, or North America are fit for service! The words on this page are not fit for reading.

well RANDY , i am a mechanic and a master welder and engineer , and from the pictures i can say that its a very highly likely that a leak will happen , and two a mechanic can see and know what metal looks like and knows when its not safe, you are someone that i would say that knows nothing, and is a loud mouth that talks out the other end. anyone can see the pipe in the picture and see its not safe , rust is there, and if there is rust it only takes a fraction of rust to weaken the metal enough under that high of pressure to have a major blow out. you sitting here judging someone else that you have no clue whom they are or if they have more knowledge of metal and oil pipe and oil lines then you. peoplle like you are why they dont let work in this feild, because of your stupid way of thinking that , high pressure lines would bo ok to use anyway even if its a risk to many others and the safety of anything or anyone.

Sure the pipes wear out. But they should be replaced before the rating is an “F” which is inviting imminent failure.
Vast sums of money are being made by these pipes, and there should be more money allocated to replace bad sections when they are at a C minus level rather than waiting until they are in such a bad state.
All of this dents their profits a bit, so it is not surprising that they are negligent to some or even a high degree. But we should make the cost of this negligence so steep that they don’t want to do it. Additional money for inspectors would also be a good idea, which can be paid by new taxes, and by really steep fines when bad things are found.
In my opinion any company that is found guilty of violating maintenance standards that threaten the public safety or huge environmental degradation should also be on probation and required to have extra inspections. At the worst case a company can be found to be a threat to the environment or the public safety, their assets confiscated and sold to new management - a corporate death penalty.
There is nothing anywhere near this strict in what most people are proposing but we cannot continue to allow companies to have such casual interest safety and the environment. If they won’t police themselves, and continue to fight the insanely tame regulations we already have, we have to come down hard and MAKE them do it with scorched earth policies.

Randy’s comment…

I’ll use YOUR example Randy…
Do you think the engineers at Ford, Chrysler, Buick etc. stroll down to your favorite mechanic’s garage, and do an “engine overhaul” for you?
Sir, you are a victim of your own media’s
PROPAGANDA!!
You ought to be ashamed of yourself, of not only, “not thinking outside the box,” but thinking “below the belt.”
Is this the best you can do Randy? :( :( :(

GREAT REPORTING! ProPublica is one of the few sources of information I trust to bring us the truth in the current corporate media climate.
BP has failing pipelines ,no surprise here after the Gulf Coast spill, the Benzene release in Texas, the BP refinery plant explosion in Texas,........

as someone that went to school to build the oil rigs and ships and learn all about the deep water drilling and piping i can say i would have to have serous thoughts about if i am safe to work at one of these sites and for how long . its not if it will happen, its when it will happen, there is a difference and should be treated as if it can blow at anytime, even if it looks safe, you can not tell whats going on inside, corrosion can happen even inside the piping, yes there is oil inside and water , or moisture and it will rust from within. so to assume that it is safe is a big mistake on everyones part. and could be your last.to replace or fix costs way less then having a major blowout, time wise or money wise. so to assume is to make a ss out of you and me get it , ass/u/me

Some more BP spill’s:
Precautions delay BP cleanup of Alaska oil spill:
Around 11,000 square feet of Alaskan tundra are affected by oil and water mixture underneath the 23 year-old pipeline, BP’s Randy Selman told reporters on a conference call.

Randy, these pipelines have already exceeded their intended design life because no one was aware that the oil deposits would last this long when they were designed. They need to be repaired, replaced or decommissioned.

Peter Koch’s leach pond in Willits, Calif. killed my son. It was used for ‘clean up’ of the Remco Hydraulics plant, which made offshore drilling & tunneling equipment, military gun barrels, nuclear actuators, etc etc. owned by Whitman Corp. aka Pepsi. ALL YOUR CHROMIUM IS SPIRITUALLY BOOBY-TRAPPED!!!!

Mr. Selman,
This is Mr. Anderson, I thnk you know me. If this article is a joke, it shouild not bother you if I request Senator Murkowski to review it and ask her to issue a legal request to have me testify before congress. If this article is a joke, as you have accused and the information that supports it is not fit for reading, then you will look well before your company. If not, your position could be short lived. I welcome your comments. Furthermore, when I am subpoenad, the 100s of documents are not going to paint a pretty picture of the neglect and incompetence. So have your day now.

Would be helpful to put the 148 pipelines at risk into context, maybe by telling us how many risky/failing pipelines are owned by other major Oil companies.

The documentary on Frontline, “The Spill” was very well made and the reporting was what I have come to expect from both Pro Publica and Front-line over the last ten years of watching, honest and accurate but not over the top.
Thank You.
