The fence is the net to stop plane that miss cable!!! It's rised to avoid some plane 'll fall down the deck or for help crew to walk on the deck too!

Its not the crash barrier, the crash barrier is placed further aft, it the barrier was placed that much forward, there wouldn't be enough room to park aircraft there at all. Its actually a wind-break/brake (spelling) , its there to protect the aircraft/equipment from the winds passing over the deck in conditions like this.

As for the rest of the pic, i think its true. Just like a wing on an airplane is designed to flex upwards and downwards (as much as 5 yards up/down in a passenger aircraft) , i think the island superstructure is designed to be able to flex. If not, it'd break clean off in any sort of harsh condition..

Thats my two cents.
