re: #505 Decatur Deb

Does the industry use a system safety process like the ISO 900x series? Something has to restore rational confidence that this isn’t a regular, predictable 10-yr cycle.

Yes and no. Depends on the piece of equipment. The BOPs have basically never been tested, we just have the opinions of the manufacturers that they work. The documentation is in a horrid state, there is no way to properly re-certify most of them without destroying them. They are old and unreliable, and probably never worked with the drill pipe used when they were made. Now that the drill pipe is much stronger… well you get the idea.
