Nearshore CPT Rigs

Wison-APB-WirelineWison-APB wireline deployable CPT system

The Wison-APB wireline CPT system is a more productive and accurate measure of the sub-bottom geology. Few companies worldwide are able to offer such a system. The advantage of a wireline CPT system over the traditional top push system is the capacity for greater production at locations where multiple drill-outs are required.

Used in conjunction with Lankelma’s Dando 9000 Rotary Drill Rig and/or the Dando 4000 Cable Percussion Drill Rig, this system has proven performance, delivering excellent data and samples, while optimising operational times in the field.

  • 90mm downhole wireline tool utilising hydraulic pressure to provide a 1m or 3m CPT push (20mm/sec) or provide a good quality Shelby sample
  • Self-tensioning remote-controlled winch, power pack, mast and sheave block
  • Lowered through the drill string and latched into place at the base of the borehole
  • Both 5cm2 and 10cm2 piezocones can be used to produce a maximum 100 mPa of tip resistance
  • Works in conjunction with Dando 9000 rotary drill rig
