Free fall HDD in Cyprus

Brownline recently surveyed a free fall HDD in the beautiful mountains on the isle of Cyprus.

The high demands on tolerance made the client decide to use the Brownline Gyro for this particular water pipeline project.

Because the Gyro measures reasonable close to the drill head in comparison with the standard magnetic tools, the accuracy is much higher, and the exact position is determent, the project has been successful completed within time and budget.

Complex factors

  • Free fall of 0.4° on 87% of the drilled trajectory
  • High demands on tolerance
  • Rough mountain area
  • 20° horizontal curve
  • Water supply for making bentonite
