But all a system check tells you is that the system is properly functioning AT THE TIME THE TEST IS PERFORMED. But since there are similar systems, with similar components in oil rigs around the world, rather than just act the dufus, fully understanding the nature of this failure (and mapping out this failure mode) is the proper way to go. And no matter what BP has done (or not done) up to this point, I'd say there are people on the case now who will do exactly that. At these depths, is enough known about how these BOP's work over time? From what I've read, apparently not. So should checks be done more often on similar rigs RIGHT NOW, should there be a redesign of certain components, should, should, should...?
But the bottom line is, until this failure mode is fully understood, the appropriate corrective action can't be determined.
