Manta CPT system
With the Manta Cone Penetration Test (CPT) System, subsurface soil conditions can be determined rapidly and accurately. This variable-weight system can be used for shallow CPTs in its light (60 kN) version and for heavier or deeper CPTs in a partially or fully (200kN) ballasted version, from smaller vessels with a suitable A-frame or crane (Mant-Light) or from larger vessels with a suitable A-Frame or a heavy crane and moonpool. The system allows penetration upto 20+ m. of a 5 cm2, 10 cm2 or 15 cm2 CPT cone into the sea bed in water depths of up to 500 m.
