description A rotating annular preventer having a body with at least one seal housed within the body, and the at least one seal being at least one rotatable seal. The at least one seal can seal the annulus around a tubular in the rotating annular preventer by actuating a first seal around the tubular by a piston and/or rotating a second seal sealingly engaged with the tubular, as the tubular is rotated, since the rotating annular preventer is configured to do both. An outlet, located axially below the piston in the side of the body, can divert fluid from an annulus surrounding the tubular.
