Nearshore cone penetration testing is not as difficult as it might seem. In case of nearshore CPT (also referred to as over-water or marine CPT) the specifications of the equipment, the operation and the procedures to follow differ slightly from land testing. It is for reason recommendable to opt for a CPT penetrometer rig that has been purposely designed for this job.
The 200 kN stand-alone CPT penetrometer set for nearshore testing is an economical rig with full CPT testing capabilities. It is because of its design and possible extra’s very suitable for cone penetration testing in relatively shallow waters, i.e. up to approx. 25 meter. The CPT set is suitable for both electrical and mechanical CPT testing, but in daily practice only used for electrical CPT only.
The CPT penetrometer set comprises a 200 kN 2-cylinder CPT penetrometer pusher, a diesel-hydraulic or an electric-hydraulic power-pack with load-sensing pump, manually operated valves, mounting frame, stainless-steel housing for datalogger and computer, etc.
