Abstract:
An RCD is used to provide a system and method for sealing a marine riser having a rotatable tubular. A bypass internal channel or external line may be used to allow fluid to bypass the RCD seal. An RCD holding member seal could be a mechanically extrudable seal or a hydraulically expanded seal to seal the RCD with the riser.
