Washington Post...at least 148 BP pipelines on Alaska's North Slope received an "F-rank'' from the company. According to BP oil workers, that means inspections have determined that more than 80 percent of the pipe wall is corroded and could rupture.
Most of those lines carry toxic or flammable substances. Many of the metal walls of the F-ranked pipes are worn to within a few thousandths of an inch of bursting...

BP Alaska spokesman Steve Rinehart said the company has "an aggressive and comprehensive pipeline inspection and maintenance program," which includes pouring millions of dollars into the system and regularly testing for safety, reliability and corrosion.
He said that although an F-rank is serious, it does not necessarily mean there is a current safety risk.-snip-
BP employees told ProPublica that several of the 120 turbines used to compress gas and push it through the pipelines have been modified to run at higher stress levels and higher temperatures than they were originally designed to handle. They also said giant tanks that hold hundreds of thousands of gallons of toxic fluids and waste are sagging under the load of corrosive sediment and could collapse.

BP technicians on the North Slope say, the detectors at some facilities are shut down nearly a third of time. When they are off-line,

The article speaks for itself - it appears BP continues to operate unsafe equipment while ignoring safety risks. Or am I missing something here?
