Site investigation and characterisation

We act on site conditions with clarity

Acteon delivers marine and offshore site investigation services that help operators plan, design and build with confidence. From seabed mapping to advanced geotechnical engineering, we provide critical data and expert interpretation to support safe, efficient infrastructure development. 

By combining innovative survey tools, proven workflows and regional delivery, we reduce complexity and accelerate insight - whether planning a cable route, installing a foundation or managing risk in frontier locations. 

Our solutions

Geophysical and geotechnical surveys

Subsea surveys and geotechnical engineering that support smarter routing, foundation and design decisions across offshore infrastructure projects. 

Geospatial surveys

High-quality geospatial data and mapping solutions that support compliance, asset integrity and environmental performance throughout the offshore lifecycle.

Solving offshore planning and design challenges

Understanding site conditions is essential for safety, sustainability and performance offshore - but traditional survey models can be slow and inflexible. Acteon transforms site investigation with intelligent tools and integrated delivery that reduce emissions, shorten timelines and improve decision confidence.

Unlocking clarity in complex conditions

Whether in deepwater, harsh climates or congested seabeds, we combine digital tools and offshore expertise to provide the data needed for accurate planning and risk mitigation.

Challenges and benefits icon.

Reducing survey cost, time and emissions

Our portable, modular systems enable faster mobilisation, lower fuel use and local vessel sourcing - minimising environmental impact and offshore exposure.

Challenges and benefits icon.

Supporting confident decisions across the lifecycle

From topographical surveys to deepwater boreholes, we help operators generate and apply site data effectively - improving safety, reducing rework and enabling smarter design and installation.

Supporting the full project lifecycle

Our site investigation and characterisation services support offshore energy infrastructure from the earliest project stages. We provide data and insight that inform permitting, foundation design, routing, risk management and installation - helping move from desktop studies to construction with clarity and control.

2H, Acteon’s Engineering consultancy, provides specification and engineering analysis/interpretation of geophysical and geotechnical data for our projects. For independent advice, contact the 2H team directly.

Our solutions in action

Explore how Acteon’s marine site investigation services support critical energy infrastructure worldwide - from high-resolution seabed mapping to remote geotechnical campaigns in deep water.

Case Studies

Deepwater geotechnical site investigation offshore Mozambique using PROD technology

UTEC, Acteon’s Geo-services business line, delivered a comprehensive deepwater geotechnical investigation offshore Mozambique using the Portable Remotely Operated Drill (PROD5) seabed drilling system, combining sampling and in situ data to characterise challenging seabed conditions.

Case Studies

High-accuracy rail infrastructure surveys

UTEC completed laser and topographic surveys at 15 Scottish rail sites for Mott MacDonald, capturing high-resolution data under live rail conditions.

Case Studies

Swift and seamless geotechnical solutions for Germany’s offshore windfarm

UTEC completed a swift geotechnical site investigation in Germany’s North Sea. From vessel mobilisation to onboard CPT and lab testing, the project concluded successfully ahead of schedule.
