PROD reaches CPT depth where others failed in challenging soils at Polish site

Creative solutions for complex conditions

UTEC, Acteon’s Geo-services business line, deployed our Portable Remotely Operated Drill (PROD) to conduct deep CPTs at 22 sites in water depths of 45–55 m. Operating through challenging geological layers – including dense sands, silty sands, boulders, and cobbles – PROD successfully acquired data to the required 55 m drilling target depth.  

By combining CPT results with drilling data and regional geophysical insights, we enabled a comprehensive geotechnical understanding of the site. The project was further supported by an automated geotechnical data management system, allowing for rapid processing and delivery to the customer. PROD’s ability to perform wash boring, advance casing and conduct CPTs in a single deployment provided an efficient and cost-effective alternative to traditional vessel-based systems. 

Innovations in action

• Deployed the PROD system, a portable seabed-based drill integrating multiple functions in a single deployment
• Enabled Cone Penetration Tests (CPTs), wash boring, and casing advancement to penetrate challenging soil layers effectively
• Real-time data capture facilitated by automated processing through our geotechnical data management system
• Reduced turnaround time and ensured high-integrity results in data analysis
• Integrated CPT, drilling, and geophysical data to support foundation engineering with enhanced confidence
• Eliminated uncertainty in critical site areas through comprehensive data integration. 

The result

The comprehensive geotechnical dataset enabled the developer to confidently validate design assumptions, refine foundation plans and reduce engineering uncertainty. By reaching the full target depth at all 22 sites, we helped ensure that project timelines were maintained and the need for repeat investigations was avoided – delivering time and cost savings for the customer.
