Those are short take off platforms for aircraft installed on Warspite in 1918 on B and X turrets. They were removed in the 1934-37 refit after they haven't been used for a long time. And this photo you posted is indeed HMS Warspite but it was taken in 1931.just a technicality: what was that cover of "face of the turret, part of the barrel" on HMS Warspite good for? thanks!

Sorry, that white thing around the area where gun barrels entered (or were coming off ) the turret are waterproof canvas.
Common name in US Navy for those things would be 'bloomers' I assume. Could be rubber like you can see here
...
Thank you, Rutim, you got me on track says:
Blast Bags, Bloomers or Gun Bucklers - Canvas, rubber or neoprene covers around the barrel of a gun where it enters the gun port. Gun ports by their nature represent holes in the glacis plate of a turret. When the guns are fired, these holes can allow overpressure or "blast" to enter the the turret, which can disrupt the operation of the turret and injure the gun crew. These holes may also permit water to enter the mounting. The use of blast bags over the gun ports provide some measure of protection from these hazards.
and I'm guessing the 16" British turret (my recent post) instead had
Gun Port Shield - Curved armor plate attached to a gun barrel such that it seals the gun port in the glacis plate, regardless of the elevation of the gun. Gun ports are by their very nature weak points in the armor protection of a gun mounting or turret. Gun shields seal these openings and are intended to provide at least some measure of protection from shell splinters. In addition, many gun shields are designed so as to keep water and weather out of the interior of the mounting or turret.
Actually, I have seen wartime photos of British 16"/45 turret on the Nelson class with tight fitting canvas covers over the gun embrasures. Other British turrets often photographed without bloomers, like the 14"/45 quad and twin on the the KGV class, have also been photographed with tight fitting canvas bloomers in mid to late war photos.
I suspect any internal weather sealing arrangement they may have had proved insufficient during the war, and as a result bloomers were added during the war.
