Geotechnical Investigations Services

We conduct geotechnical investigations to analyze soil, rock, and subsurface conditions using corers, CPT tools, and drilling systems. Our data supports safe drilling, pipeline installation, and offshore infrastructure development.

Overview

Geotechnical Investigations

The Geotechnical department of GOSL is responsible for deploying Geotechnical Soil boring Rigs, CPT Machines, Drop Corers and Box Corers to collect soil samples offshore and carryout Soil Laboratory Analysis based on client scope of work. Geotechnical investigation is a critical aspect of offshore infrastructure installation works.

Our Core Capabilities:

GOSL has the capacity to carry out Geotechnical investigations from mud line to 100m below sea bed or as may be required by client. Some critical investigations include the following:

  • Load bearing capacities of piles for subsea structures.
  • Shallow geology for pipeline installation works offshore.
  • Cone Penetration tests
  • Atterberg limits of soil properties.
  • Density of soil properties
  • Subsoil investigation for subsea channel HDD crossings.
  • Rig Stability for offshore position analysis.
  • Deep offshore water borehole drilling and many more.
  • Laboratory Services.
  • Soil Resistivity Tests. etc
 

The department is manned by very experienced Geotechnical Consultants who have proven records in the Oil and Gas Industry.

Why It Matters

Geotechnical data forms the foundation for safe, efficient, and compliant offshore projects. By revealing subsurface conditions and potential geohazards early, it allows project teams to mitigate risks, optimize engineering designs, and prevent costly delays. Through detailed site investigations, sampling, and laboratory testing, accurate geotechnical insights guide the selection of appropriate foundation solutions and ensure that offshore structures are designed to withstand environmental and operational stresses.

We deliver these services with precision, consistency, and a deep commitment to quality, ensuring that every project we support is built on a solid technical and environmental foundation.

Why Choose GOSL?

  • Rapid and flexible deployment.
  • Reduced mobilization costs with locally maintained equipment.
  • Experienced Nigerian teams available 24/7.
  • Proven track record across major Oil & Gas projects.
