B. GEOTECHNICAL INVESTIGATION

(Marine and Offshore)

We have steadily expanded our marine geotechnical capabilities to meet the increased demand for integrated geological and geophysical surveys from Shore to Deep Ocean including, seabed sampling, In- Situ testing, soil sampling and rock coring in water depths up to 1500mtrs. Some of our geo-technical investigations expertises are as below:

  • Mobilize suitable marine spread depending on the water depth
  • 5-20m: Jack up Platforms
  • 20-100m: Four Point Mooring Vessel
  • >100m : DP Vessel
  • Drilling in all types of Soil & Rock
  • In-situ testing including downhole CPT
  • Continuous CPT using seabed operated unit
  • Rig based coring
  • Vibro coring
  • Drop & Grab sampling
  • Offshore Laboratory
  • Onshore Laboratory
