Geotechnical and Geophysical

Collecting and using geotechnical, geophysical and site survey data are key to successfully managing your subsea construction project. Without it, offshore projects are exposed to substantial and often unnecessary risks.

We can specify, manage, report and use the data to minimise your geotechnical risks. You will benefit from a reduction in unexpected seabed conditions, which will increase the value of your project.

Our experienced consultants can provide assistance in all areas of seabed survey, geotechnical and trenching engineering, including:

  • Site or route desk studies
  • Specification and management of geotechnical and geophysical surveys
  • Geotechnical and geophysical data interpretation and integration
  • Geotechnical hazard assessment and route optimisation
  • Geotechnical design of seabed structures and anchors
  • Pile design, pile driving assessment, and pile monitoring
  • Jack up foundation stability assessment and leg penetration
  • Conductor setting depth and borehole stability
  • Pipeline-soil interaction parameters for axial, lateral and upheaval buckling studies
  • Burial assessment for ploughs and trenchers, and assistance with asset selection for pipeline and cable burial
  • Backfill engineering
  • Pipeline on-bottom stress analysis, span analysis and seabed preparation
  • Decommissioning offshore foundations, pipelines and cables
