Patent abstract
A connection for sub-sea use employs locking dogs that are isolated from seawater and a backup system for operating the backup sleeve to the dogs. The normal actuation system for the backup sleeve is also isolated from seawater exposure. The set position of the backup sleeve is positively retained against the prospect of axial movement that could be triggered by transmitted vibration into the connection.
