I think that's slightly harsh. I accept you have your doubts and have seen the history of the Super Puma on the North Sea, but as an aircraft type, it really has an exceptionally good track record. I don't think I know of a single type that has entered service without some inherent faults that have been solved with engineering fixes over the following years.
Thats why I think the EC225 was always a good choice for the North Sea, being a further development of an existing proven design, with a solid design pedigree you can trace back to the original Puma in the 70's. The pilots certainly seem to love it and you don't hear many complaints especially when it comes to night flying or landing at Aberdeen in the fog !!
