Neptune 3000 CPT System

The Cone Penetration Test is based on pushing an instrumented cone into the ground at a constant speed, with continuous measurement of the cone end resistance, the friction along the sleeve of the cone, and the pore water pressure.

  • Maximum penetration 10m
  • Real time control and data display
  • Water depth rating 3000m
  • Frame and cone inclination
  • 2 & 5cm2 piezocones
  • Easily deployed compact subsea frame
  • Single coax connection for power & data
  • Easy to operate WindowsTM based PC controls
  • Automatic safety cut-outs
  • T-bar testing
