Experience that delivers

geotechnical expertise for offshore energy and infrastructure projects

Success offshore depends on understanding how the seabed will behave. That knowledge shapes practical engineering solutions, helps manage risk before construction begins and provides greater certainty throughout project delivery. In environments where intervention is difficult and costly, robust geotechnical engineering advice is essential to achieving safe, efficient and reliable outcomes.

That understanding comes from informed and proven geotechnical consultation. Our specialist engineers bring practical experience from oil and gas, renewable energy and infrastructure projects in challenging subsea environments. We support clients from concept through to build, commissioning and beyond, providing site characterisation services, geotechnical design and analysis for foundations, anchors and pipelines, installation supervision and operational support.

Foundations engineered for offshore performance

Survey support

We plan, scope and supervise geophysical and geotechnical survey campaigns, working alongside our clients to ensure data quality, coverage and accuracy – providing a reliable basis for decision-making and reducing risk before detailed engineering begins.

Site characterisation

We interpret geophysical and geotechnical data to build robust ground models, defining seabed and subsurface conditions, geohazards and design parameters – underpinning every stage of offshore design, from concept selection through to detailed engineering.

Fixed-bottom foundations

We design foundation systems for offshore platforms, wind turbines and subsea structures, including piled, gravity-based and suction-installed solutions. Our scope extends to jack-up leg penetration and stability assessments, supporting safe and efficient installation.

Anchors for Floating Structures

We design anchoring systems for floating infrastructure, including wind turbines and oil and gas structures. We assess anchor piles, suction anchors, drag anchors and dynamically installed anchors, with anchor selection matched to seabed conditions, mooring loads and installation constraints.

Pipelines and cables

We provide geotechnical input for subsea pipeline and cable routing, burial and protection studies and pipe-soil interaction assessments.  Theses analyses feed directly into pipeline and cable design and support optimisation that balances robustness and cost across the asset life.

Construction and Decommissioning

We support clients through construction, installation, operations and decommissioning, providing independent technical representation, contractor oversight and engineering advice at every stage — helping manage risk and protect asset performance across the full project lifecycle.
