Yep, and some companies are self-policing. Which is why they have far fewer problems.
A couple of decades back many land drilling contractors saw the wisdom in preventing accidents and started really proactive safety programs. That blossomed into full blown education programs for drillers and toolpushers (rig managers, for you ginsels out there) covering well control and other more advanced topics.
The results are fewer accidents and fewer trainwrecks, and lower expenses as a result. This is where humanitarian, environmental, and economic reasons all come together to motivate people to get it right.
I worked for my “uncle” (second cousin actually - I think!?) for a couple of summers on an oil rig during college. One summer in Wyoming, the next in Oklahoma. He was the boss on the rig. Even the company men knew it, and would agree with whatever he deemed the thing to do, and then helped him do it.
He ended up as a driller on some “super rig” in Oklahoma before he retired. I can’t remember now the name of the drilling company he was with when I was with him. (Although I think I still have my 30 year-old windbreaker around here somewhere with my “Safety First” patch on it for not hurting myself that first summer!)
I sure hope the driller and tool pusher on the BP rig survived.
