212man....your profile says you drive 155's in Nigeria.....anything you can add to this discussion? Any sort of empirical data you can share.....for those of us that are operating 155's in hot offshore places....in the Gulf of Mexico we are being confronted by the same thing on the two 155's operating there.
What is causing the unusual number of engine changes? Shell is supposed to be the fleet leader in hours now....and in Nigeria...that means Bristow thus it would seem you might know something that could help the rest of us.
