Abstract
A pressure relieve valve (PRV) secures to the rotating control device (RCD) in a drilling operation. The PRV located at rig flowline secures to a PRV line, such as PRV piping that bypasses the MPD choke, MPD system, UBD systems, and other flow control device(s). The outlet of the RCD is routed via the pressure relief valve to discharge to a safe contained area. Such discharge relieves overpressure of the wellbore to a contained environment via the rig flowline.
