The LiMAR Velocity String System encompasses a Surface Pack Off, Grapple Connector, Sliding Side Door, Standing Valve and Pump Out Plugs which can be utilised in any of hang off application where live well deployment and recovery are required.

The Grapple Connector is designed to make the connection to the CT at either end of the string. The Standing Valve permits one way flow during production and the SSD allows communication to the production tubing above the lower packer for gas lifting or displacing fluids. The pump out plugs feature a total of four O-Ring grooves which provide a double barrier either side of the shear screws, designed to retain the pump out plug during deployment.


  • Connecting interface between the Coiled Tubing and the BHA which provides a pump out barrier to initiate production, a Standing Valve with retrievable internals to control flow direction, an SSD to aid in offloading, a Surface Pack Off to create a seal around the CT String and a Recovery Dart to isolate the string at the Standing Valve for recovery.
