A rotating control device for a tubular string includes a body, a housing assembly, and a clamp device. An annulus is formed between the body and the tubular string. The housing assembly includes an annular seal configured to seal off an annulus between the tubular string and the body. The clamp device is configured to selectively permit and prevent displacement of the housing assembly relative to the body. The clamp device includes a first clamp section and a second clamp section coupled to and pivotable about a pivot, and a motor positioned between an end of the first clamp section and an end of the second clamp section, wherein the motor is configured to move the ends of the first and second clamp sections relative to each other.

Remote operation of a rotating control device bearing clamp and safety latch

An RCD can include a housing assembly which contains a bearing assembly and an annular seal which rotates and seals off an annulus between a tubular string and an RCD body, a remotely operable clamp device which selectively permits and prevents relative displacement between the housing assembly and the body, and a remotely operable safety latch which selectively permits and prevents unclamping of the clamp device. A method of remotely operating an RCD clamp device can include remotely operating a safety latch which selectively permits and prevents unclamping of the clamp device, and remotely operating the clamp device while the safety latch is in an unlatched position, thereby unclamping a bearing housing assembly from the RCD body. Another RCD can include a remotely operable clamp device which selectively permits access to an RCD body interior, and a remotely operable safety latch which selectively prevents unclamping of the clamp device.

An RCD can include a housing assembly containing a bearing assembly and a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents displacement of the housing assembly relative to the body. A method of remotely operating a clamp device can include rotating a threaded member which is secured relative to an RCD body, and displacing a clamp section in response to the threaded member rotation, thereby selectively securing and releasing a bearing assembly and an annular seal relative to the body. Another RCD can include a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents access to an interior of the body, the clamp device including a motor which rotates a threaded member.
