Abstract
A rotating control device (RCD) for a drilling system includes an outer housing, a seal element positioned within the outer housing and configured to form an annular seal about a tubular, and a damper assembly positioned with the outer housing and configured to dampen forces exerted on the seal element as the tubular rotates, moves axially, or both.

A rotating control device (RCD) for a drilling system, the rotating control device comprising:
- an outer housing;
- a seal element positioned within the outer housing and configured to form an annular seal about a tubular;
- and
- a damper assembly positioned with the outer housing and configured to dampen forces exerted on the seal element as the tubular rotates, moves axially, or both.
A rotating control device (RCD) for a drilling system, the RCD comprising:
- a seal element configured to form an annular seal about a tubular;
- a damper assembly configured to dampen forces exerted on the seal element as the tubular rotates, moves axially, or both;
- and
- a piston actuation system configured to provide active control to adjust a sealing force of the annular seal.
A method of operating a drilling system, the method comprising:
- placing a tubular through a rotating control device (RCD);
- actuating a piston actuation system to compress a seal element to cause the seal element to form an annular seal about the tubular;
- and
- dampening, via a damper assembly, forces exerted by rotating the tubular, moving the tubular axially, or both while the seal element forms the annular seal about the tubular.
