Sorry, must having been having a senior moment when I wrote my last post, coupled with a large dose of naivety. Thanks for putting me back on the straight and narrow. I'd obviously forgotten what an accepted practice it is to stick your tail into solid objects during the last few moments of a landing offshore. I guess knowing the crane is an obstacle just goes to confirm what a standard practice this must be these days.
I must be getting old as I find myself saying "it was never like that in my day"
(Just to confirm: I'm not having a go at the pilot - I'm having a go at those who believe it's a non-event, Dauphin or not!)
