Shell certainly makes this claim in the bochure above, dated June 2010:
Process safety in Shell
Our assets are safe and we know it
Given the nature of the risks involved, ensuring the safety and integrity of our assets is paramount to Shell. For us, process safety means making sure our facilities are well designed, safely operated, and properly inspected and maintained.
SM may want to consider these words in relation to the fact Shell were fined over £1mn this week for an explosion in the Bacton gas plant in the UK that would probably have killed 10 people if they were not doing a shift change in the admin block.

Shell have also picked up record breaking HSE fines at their Stanlow refinery after an oil spill and even their head office (after a fire).
What is the real outrage, that people listen to Shell Aircraft's nonsense.
