Heave Simulation - Video

0
In this video technicians simulate rough ocean heave by using a forklift to push up against the underside of the drill head and then free fall the forklift. You can observe the operator manipulating the feed lever and relief valve to compensate the drill head movement to match the movement of the forklift. Then, with the fork lift removed, the operator demonstrates feed pressure adjustment by turning IN or OUT the relief valve causing the drill head to either float UP or DOWN based on the amount of tooling weight below the drill head.
