Offshore Geotechnical Investigations for Oil & Gas

Geoquip Marine delivers offshore geotechnical site investigations supporting oil and gas developments worldwide. Operating in shallow, deep and ultra-deep water environments, our specialist drilling vessels, experienced offshore teams and integrated laboratory capability generate reliable seabed data to support drilling operations, platform installation and subsea infrastructure development.

Supporting offshore field development

Our offshore investigations provide the geotechnical insight required to support safe engineering design and installation of offshore infrastructure.

Geoquip vessels are equipped with advanced drilling systems and automated drill floor technology designed to minimise manual intervention and enhance operational safety.

Typical investigations:

  • Platform and jacket foundation investigations

  • Jack-up rig site assessments

  • Pipeline and subsea infrastructure route investigations

  • Seabed sampling, CPT and deep coring

  • Downhole logging and in-situ testing

  • Laboratory testing and geotechnical interpretation

Integrated data delivery

Our integrated delivery model combines offshore investigations with advanced laboratory testing and engineering analysis, enabling consistent sample handling, reliable testing and high-quality datasets to support confident engineering decisions.

  • Offshore geotechnical site investigations
  • Borehole drilling and sampling
  • Seabed CPT and in situ testing
  • Laboratory testing and soil characterisation
  • Data interpretation and reporting
  • Offshore engineering support

By integrating offshore operations with onshore engineering and laboratory teams, we maintain full control over data acquisition, analysis and quality assurance.

Designed for challenging environments

Offshore projects are increasingly moving into deeper water, more remote locations and more challenging ground conditions. Geoquip Marine’s DP2 fleet and specialist drilling systems are designed to operate safely and efficiently in these environments, delivering reliable data where it matters most.

  • Safety and operational reliability
  • Data quality and traceability
  • Environmental responsibility
  • Schedule certainty
  • Geoquip Marine has supported offshore oil and gas developments across multiple regions, delivering geotechnical investigations in shallow and deep-water environments worldwide.
