MARINE DRILLING & TESTING EQUIPMENT

SEA DRILL

Gregg Drilling has designed a robotic deep sea drill capable of operating in water depths up to 3000 meters. Designed by geotechnical engineers, the deep sea drill can obtain high quality undisturbed soil samples and soil cores up to 150 meters below the sea floor. The drilling methods employed include wire-line rotary and push sampling with HWT or PQ (85mm) sized tooling.

Cone Penetration Testing (CPT) and seismic CPT can be conducted using Gregg’s patented hydrostatically compensated cone. The entire unit is controlled robotically from the surface and incorporates proven Schilling telemetry and control systems. The deep sea drill can be deployed with numerous interchangeable foundation options depending on the seabed conditions.

To reduce cost and mobilization time, the entire unit ships in four standard shipping containers including the control and operating container. Operating from vessels of opportunity allows Gregg to reduce mobilization cost and respond quickly to clients' needs.
