摘要
A latch assembly is described for use with a rotating control device. The rotating control device provides a rotating seal to permit pressure control in an annulus surrounding a rotating tubular member such as a drill string in an offshore drilling operation. The latch assembly is operable to engage and disengage a body of the rotating control device from a remote surface location by wireless communication. An on-board actuation system is carried by the latch assembly such that no energy lines (hydraulic or otherwise) are required to couple the latch assembly to the surface location. The latch assembly may include both an operating latch mechanism and a running latch mechanism to selectively couple the latch assembly to one or both of the body of the rotating control device and a tubular member such as a drill string or other conveyance for running and pulling operations.
