Geophysical and geotechnical surveys
Understanding offshore ground conditions is critical to safe, efficient infrastructure delivery. Acteon combines advanced geophysical survey methods with specialist geotechnical engineering to deliver the insight needed for confident design, routing and installation.
Our flexible approach, modular systems and experienced teams support fast, low-impact offshore geotechnical site investigation. Whether planning in shallow waters or drilling in deep, we help operators act early, reduce risk and optimise foundation performance.
Geophysical and geotechnical surveys delivered in the last 10 years
Acting on complexity below the seabed
We help operators reduce risk, emissions and cost by generating high-quality subsurface data across the lifecycle. Our geophysical and geotechnical survey services combine field-proven technologies with expert interpretation to support everything from early-stage assessment to pipeline inspection surveys and foundation design.
Delivering faster results with lower emissions
Our systems reduce offshore time and fuel use - enabling up to 50% fuel savings and 9.4 tonnes CO₂ reduction per six-person deployment.
Improving accuracy and decision confidence
Our in-situ shear strengths using our HTPC are 15-20% greater than laboratory testing data – saving you valuable time, cost and reducing uncertainty in the data.
Cutting cost and risk with flexible mobilisation
From topographic and hydrographic surveys to deepwater geotechnical surveys, we scale quickly and operate effectively in remote or harsh conditions.
Clear the noise. See the pattern.
Advanced geotechnical processing connects borehole logs, CPT data and laboratory results that shape smarter offshore decisions.
Geophysical surveys
Supporting safe installation through subsurface clarity
Our geophysical surveys map the seabed and sub-seabed to inform key decisions on routing, installation and safety. Using high-resolution tools and digital workflows, geophysical experts identify bathymetry, sediment layers and hazards that may affect offshore activity.
Our technology
We deploy a flexible ecosystem of tools optimised for fast, accurate results in any marine setting. We have a variety of geophysical equipment available for rental - contact the team to find out more.

Engineering insight for offshore ground conditions
Building on the extensive track record of Benthic, now UTEC, we deliver offshore geotechnical site investigation through in situ testing, sampling and borehole data. Our fleet includes portable remotely operated drill (PROD) – a modular seabed drill system that delivers downhole geotechnical data without needing a drillship.
Our technology
From deepwater to shallow water sampling, cone penetration tests (CPT), surface seabed soil sampling (GEOROV), and other in situ tests, we provide the right toolset for each project - integrated with data systems and expert interpretation.
