Submersible Directional Drilling Machine

 

This machine is developed for the directional crossing drilling at a depth of 50 meters or more without personnel to operate underwater. It can be used for salvage operation of sunken ships or horizontal directional drilling projects underwater.

It adopts continuous pipe-drilling technology, which is the main difference from conventional directional drilling machine working on the ground and there is no need to connect and disassemble drill pipe during underwater operation. In addition, all connections of wired guidance system before launching should be completed before launching to make underwater unmanned operation possible. The length of continuous drill pipe should be connected on the water according to the crossing length. There is a floating device to keep the part of the continuous pipe that does not enter the soil in a suspended state under water.
