Wow, there is a big admission SM!
I wonder how far along Shell is actually along with implementing 7/7, 5 years after launching it.
Certainly at 80,000 hours pa the 2009 GOM accident has screwed the target of 1 fatal(?) accident per million hours (the 5 year and 10 year Shell avarages are at least 2.5 by my calculations). I also suspect a plataeu has been hit by Shell, just like SM keeps point out the airline industry has hit.
