发明名称 Riser rotating control device
摘要 <p>A latch assembly (210) is connectable to a riser. A rotating control device (100) can be positioned with the riser, sealing the rotating control device with the latch assembly and removably latching the rotating control device to the latch assembly and to the riser. The latch assembly can be remotely actuated. The latch assembly can provide an auxiliary safety mechanism (222) to provide a backup actuation mechanism to unlatch the rotating control device from the latch assembly. The latch assembly can be bolted to the riser. Alternately, the latch assembly can be latched with the riser using a similar latching mechanism as used to latch the latch assembly to the rotating control device. A pressure transducer protector assembly can protect a transducer for monitoring wellbore pressure in the riser. A remote indicator panel can indicate the status of the latch assembly.</p>
