Abstract:
A rotating control device is remotely hydraulically latched and unlatched with a docking station housing for use and removal, respectively. The system and method allows for interactive lubrication and cooling of the rotating control device, as needed, along with a supply of fluid for use with an active seal. A first sensor and a second sensor can be used to detect temperature, pressure and density of the supplied fluid at different locations and this data can be compared using a central processing unit (CPU). Also, a sensor can be used to detect the revolutions per minute of a rotating seal of the rotating control device and fluid can be provided to the rotating control device responsive to the detected revolutions per minute.
