The D-value of the AW609 is less than that of an S92 which is certified for almost all decks in the North Sea. S92 d-value is 21 (20.88). I believe the Aw609 is a little less the 20. In addition full icing clearance and performance class 1 as well as cruise speeds of 250kts, it is easy to see some real advantages to the offshore sector.
