Squib;
Surely Shell management will do what Shell management (and all the other oil companies) do whenever that recommendation is made; They'll ignore it. (Or follow it until it causes production or exploration delays).
There are lies, damn lies and oil company safety cases.
Shell management I do wonder if you realise just how many of us involved in commercial avaition and aviation safety cases think what a total c*** you are. Lets face it all of our ops manuals, AFMs and certification standards are there for safety, not decoration.
Personally I also add the proviso "would I let my family fly with that operation?" Trust me if the operation had any form of Shell input there would be no way.
