Abstract:
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.

Claim (Index 12):
A rotating control device for maintaining a seal against a rotating tubular member, the rotating control device comprising:\n a body defining a latch profile thereon; a latch assembly including an operating latch mechanism defining a latch profile corresponding to the latch profile defined on the body, the operating latch mechanism responsive to wireless signals to release hydraulic fluid from at least one hydraulic reservoir carried by the latch assembly to permit or restrict movement of the operating latch mechanism between an engaged configuration and a disengaged configuration with respect to the body; a bearing assembly coupled to the latch mechanism; and an annular seal member coupled to the bearing assembly such that the annular seal member is rotatable with respect to the body when the operating latch mechanism is in the engaged configuration with respect to the body.
