There is no commercial imperative to bring the 225 back into service, North Sea or internationally. There is no shortage of S-92 capacity to fill the heavy requirement and Super Mediums are increasingly filling intermediate requirements.
Bringing a 225 on contract would probably displace a 92 or 189 /139 which are all cheaper to operate anyway. The 225 has always been more $ hourly than the 92 and with changing MGBs every 1000 hours will only be more expensive again. So, as an operator, one would really have to want to rather than need to bring it back.
We have all been told that this is the most scrutinised MGB ever, 3 or 4 times now. This time I don't believe it and I won't be putting any passengers in it.
