Somesuch,
I keep on saying it you keep on missing it (I'm sure it is bad form quoting oneself):
As I said previously, there is likely to be an airspace requirement (similar to that for the EC225 operational restriction) that will mandate the operational limitation on the UK continental shelf. What more is there to say?
That is, it will apply to any helicopter flying to a UK offshore installation (from wherever they originate).

I have to add that if you think that the UK has been behind the rest of the world, you have not been following the debate (over two decades).
