Abstract
A protective subsea housing for protecting an equipment space enclosed by the housing has an access opening in a wall of the housing for providing access to the equipment space by an unmanned underwater vehicle (UUV). The housing has a closure that is movable by translation, or by rotation relative to an axis transverse to or extending through the wall, to open and close the access opening, and an operating member, such as a rotary coupling, that is positioned outside the equipment space and is engageable and movable by the UUV to move the closure.
