Subsea Internal Riser Rotating Control Device System and Method |
| 摘要 |
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 seal assembly seal could be a mechanically extrudable seal or a hydraulically expanded seal to seal the RCD with the riser.
