Abstract:
1. A rotating control device, comprising: a housing assembly which contains a bearing assembly and at least one annular seal which rotates and seals off an annulus between a tubular string and a body of the rotating control device; a remotely operable clamp device which selectively permits and prevents displacement of the housing assembly relative to the body, wherein the clamp device includes first and second clamp sections which pivot about a first pivot; an actuator coupled to the first and second clamp sections, wherein elongation of the actuator unclamps the claim device; and a remotely operable safety latch including an engagement member which selectively permits and prevents unclamping of the clamp device, wherein the engagement member pivots about a second pivot, wherein an axis of rotation of the first pivot is perpendicular to an axis of rotation of the second pivot, and wherein the engagement member is configured to engage with the actuator, locking the actuator in a contracted position, preventing elongation of the actuator.
