DAVIS, California -- Gregg Drilling and Testing is beginning in-water testing of its new Cone Penetration Testing (CPT) system. Once harbor testing is complete, the system will then be sent to work offshore in June.
Schilling Robotics supplied the control system and hydraulics for the Gregg-designed CPT system. The control system consists of electrical and communications components, subsea hydraulics, along with topside hardware, console components, and advanced component monitoring, and diagnostic software.
Gregg's CPT is performed using a cylindrical penetrometer with a cone tip penetrating the seabed at a constant rate. The resulting measurement analysis reveals soil conditions, including soil type, stratigraphy, and shear strength parameters. Typical uses of the submersible Gregg CPT unit may include pipelay, seabed foundations, cable routes, ports and harbors, and environmental surveys.
