Bridge wing covers

A rather curious addition made to ORIANA during her winter refit which has seemed to go largely unnoticed are two canvas covers above the ship's bridge one above each wing.
Seemingly covering the span of the exposed area of both wings the covers appear to be formed from a metal support with cover attached to it.
The addition of the covers go some way to explaining the two small "windows" which were added to each wing during the refit
Below are two images showing the starboard wing and its cover.
