This accident reminds me of two high profile airline accidents.
One is the Air Korea 747 CFIT accident in Guam. In both accidents training emphasised certain issues (in that case the visual aspects of the approach, in the Cougar case the indications of MRGB failure), fostering false expectations and not emphasising the hazards. As a result the training did not adequately prepare flight crews for the challenges they faced.
The other is the Transat A330 'flying on empty' accident in the Canaries. In that case poor indicate of the failure state resulted in confusion and assumption of sensor error, just like in the Cougar accident.
Incidentally in the Transat case, TC fined the operator a record amount for the errors that caused the fuel leak. I wonder if TC will fine anyone in this case.
I don't think any competent offshore operator with an SMS would be so lazy as to just use the notes from their sumulator provider as a checklist.
