Job Description:
Challenging project crossing a wide harbor to lay a 30kV line between a power plant and a wastewater treatment plant.
Started in the north side, close to the power plant.
Drilling straight parallel to the main road (100m surface coil). 80m after reaching the water edge, started a right turn (100 deg) until the end. Punching out just 20m after reaching exit side.
Limestone started 20m below sea level. On the way down we had some spots with bad ground (stones or gravel). On the way up, last 40-50m ground was extremely soft, in spite of this we managed to punch out successfully!
