In association with one of our strategic partners GISCA can offer consultant and survey services including global positioning systems, bathymetry, pipeline/cable route evaluation, 2D/3D seismic reflection, seismic refraction, seismic or electromagnetic tomography, ground penetration radar, resistivity profiling and in-hole seismic logging (crosshole, downhole).

  Main equipment available:

• Seismic sources and geophones for seismic reflection, refraction and in-hole arrays
• DGPS (Differential Global Positioning System)
• Bathymetric Marinetek PSC-200 sounder
• Side Scan Sonar
• Echo sounder
• Sub bottom profiler

Geotechnical Investigation:

GISCA can offer onshore and offshore geotechnical drilling and sampling services up to depth of 250 m or more, operating in environments with water depths up to 1000 m. In situ testing capabilities include PCPT, field vane tests and downhole shear wave velocity measurements. On-board soil testing laboratories can also be supplied.  

  Main equipment available:

• Sprague Henwood 40 C and VM Joy C 35 drilling systems
• Heliportable drilling system
