Lockdown mechanism for wellhead connector
Patent
·
OSTI ID:6361414
A connector for subsea wellhead bodies comprises a connector body adapted to be connected to a subsea wellhead body in generally coaxial alignment therewith. Latches carried by the connector body are engageable with the wellhead body to so connect the bodies. An actuator is operatively associated with the latches and longitudinally extendible for extending the latches into such engagement with the wellhead body. A lock assembly is provided for selectively locking the actuator in its longitudinally extended position. The lock assembly comprises inner and outer lock portions, the outer portion telescopically receiving the inner portion with a tight interference fit. The lock portions are oriented generally parallel to the path of movement of the actuator. One of the lock portions is connected to the connector body, while the other is connected to the actuator. Means are provided for selectively introducing pressurized fluid between the inner and outer lock members to forcibly radially separate them and allow relative telescopic movement therebetween.
