Man’s search for oil and gas reserves continues to bring new challenges. Deep Water has become the new frontier in this quest. Like any new venture, this search has encountered different, unexpected problems. One of the main challenges is the motion the drilling rigs, drill ships and production platforms experience. This movement may be caused by weather, tidal changes, “loop currents”, and other anomalies.
Drilling rigs use compensated draw work, or compensated blocks, to correct for this motion. But what do you do once the rig is no longer on location? Devin International, Inc. answered the call by introducing the Motion Buster in early 2003. The Motion Buster incorporates a passive compensation system, using air/nitrogen for the energy source. This structure corrects the vertical heave that plagues SPAR platforms, and assists minimally for the lateral motion encountered on TLP’s.
But, TLP’s must also adjust for what the industry calls a “gimbling” of the riser. This gimble causes the riser to move in a figure 8 motion over an undetermined period of time, i.e. 6 to 24 hours. The Devin Gimble Table allows compensation of the injector head on an x-y axis, up to 2 degrees. Devin’s Gimble Table also compensates laterally on a z axis a total of 18”.
The x-y compensation is accomplished using 4 cylinders, each with its own accumulator bottle. Z axis compensation is accomplished with a glide table mounted on nylatron. The Gimble Table utilizes nitrogen over hydraulics as the energy source.
Devin’s total compensation package, The Track Stack GT, incorporates the versatility of the Track Stack Jr, the proven vertical compensation of the Motion Buster and the new technology of the Devin Gimble Table. Devin’s experienced team of offshsore technicians is ready to tackle your next challenging project.
