Norsk Helikopter Service. Being ran by ex CHC HS guys apparently.

NHS - Norsk Helikopterservice - The Premier Helicopter Operations Within The Norwegian Continental Shelf
Not quite sure how they say they are "The Premier Helicopter Operator within the Norwegian Continental Shelf" if they haven't got any helicopters yet!
Shame that they want to use a mixture of the names of the companies that Bristow and CHC took over rather than come up with a complete new one.
