Geotechnical Engineering Capability

Background

Geotechnical engineering is always a major aspect on subsea and pipeline projects and operations. Atteris is unique in the industry for its combined expertise in all aspects of subsea and pipeline engineering, including geotechnical engineering.

With Atteris working on your project, most geotechnical engineering aspects can be covered in-house, including:

  • Geological engineering studies and assessments
  • Interpretation of geotechnical reports
  • Scoping, managing and supervising geophysical and geotechnical survey programs for subsea and pipeline projects
  • Management of geotechnical laboratory testing
  • Definition of geotechnical design data
  • Foundation designs for small to medium size structures, including pipeline crossings
  • Seabed material scour and liquefaction assessments

One particular area of engineering pioneered by Atteris in 2005 is the development of engineering methods to assess the tri-partite interaction of subsea structures (e.g. pipelines), the surrounding fluid (hydrodynamic loading) and the seabed. This work has resulted in the development of the UWA O-tube project.

Work Performed by Atteris

Examples of major projects where Atteris engineers have provided this service:

  • Chevron Australia’s Wheatstone Project
  • Woodside Energy’s Pluto LNG Project
  • Quantum Energy’s Reindeer/Devil Creek Project
  • Woodside Energy’s Otway Gas Project
  • Woodside Energy’s Browse Platforms Project
  • Woodside Energy’s Trunkline System Expansion Project
  • Woodside Energy’s Cossack North Project
  • Woodside Energy’s Lambert Deep Project
  • BHPB’s Angostura Project
  • BHPB’s Pyrenees Project.

In addition, Atteris engineers have provided this service on numerous other small and medium size onshore and offshore projects.

Benefits

The benefit of being able to rely on a single engineering consultancy for subsea, pipelines and geotechnical engineering removes an often complicated engineering interface. Old-style subsea and pipeline engineering houses require this interface with a geotechnical consultant out of necessity.

Atteris engineers do understand the limitations of their expertise and rely upon experts in the industry for highly complex geotechnical engineering problems. They then have the ability to lead these specialists adequately due to their foundation geotechnical engineering expertise, in combination with the knowledge of the reason for the problem and what the solution to it should do.
