  • Telescopic joint mini control panel
    Patent number: 8720583
    Abstract: A method and apparatus for determining and reacting to an upper packer failure in a riser slip joint. An upper packer failure is determined by comparing pressures at two points in the upper packer pressure circuit using a differential pressure valve. In the event of a failure of the upper packer, a secondary pressure source is used to energize a lower packer in the riser slip joint.
