GEOEXPLORER

The Geoexplorer is a 4-point moorage vessel, Capable of performing geotechnical and geophysical studies at 200 meters deep.
The vessel was reformed in 2014, where perforation and sampling equipment were installed, making the Geoexplorer a very effective, liable and low cost operating system.
Features: 
350-meter perforation in combined depth wells
Downhole sampling (Cone Penetration test/ CPT)
Ocean bed CPT
Piston sample extraction
Vibro sample extraction
Geophysical studies
Oceanographic studies
Geotechnical lab.
