Bardex is
the world's leading manufacturer of hydraulic Gripper Jack Skidding
Systems, including those in use on almost all multi-well drilling
platforms in the North Sea.
The term "Gripper Jack" was coined by Bardex engineers
who developed the first Gripper Jack nearly 40 years ago. Bardex is
the industry standard and world market leader.

Rig Skidding System.

|
The key element
in any Bardex Skidding System is a hydraulic friction-lock device (aka
"Gripper")
on which is mounted the double acting hydraulic jacking cylinder(s)
(aka "Jack"). The Gripper clamps
the flange of the beam on which the load is resting and acts as a moveable
reaction point for the Jack.
The
table below explains the basic sequence of steps which Bardex Gripper
Jacks use to move such massive loads.
|
| Gripper Jack Operating Sequence |
1)
Gripper Jack Assembly mounted to jacking beam and attached to load.
|
2)
The Gripper is pressurized, locking it to jacking beam.
|
|
3)
Pressure is maintained in Gripper; the Cylinder is extended,
moving the load.
|
|
4)
Pressure is released from the Gripper unlocking it from jacking
beam.
|
|
5)
The Cylinder is retracted, moving the Gripper into position
for next move.
|
A complete system includes at least two Gripper jacks, plus the
requisite
Hydraulic Power Unit,
operators control console, and the interconnecting high pressure hydraulic
hoses. Lateral and longitudinal movements are accomplished through
the use of four Gripper Jacks, two for the "X" movement and two for
"Y" movement, selection being simply effected by a valve manifold
on the control console.
