WISON-APB for water depths up to 1,000 m

The WISON-APB-1000 is designed for soil testing at depths up to 1,000 m (water depth + drilling depth). It requires a drill string with an inner diameter of at least 4” (101,6 mm) and a drill tower clearance of 11 m.

Pushing tools are available in three types: 

  • 50 kN with a 3 m tool
  • 100 kN with a 1 m tool 
  • 150 kN with a 1.6 m tool

The WISON-APB-1000 comes with an electric winch that is self-tensioning for heave compensation. The winch allows a travel speed of max 2 m per sec of the tool  inside the drill pipe. The umbilical provides data transfer and hydraulic power.
