Integrated solution for installation of over 300 piles on major wind farm

To support this critical jacket installation phase, we delivered a fully integrated solution combining subsea cutting, piling operations, structural monitoring, and real-time positioning. The project leveraged the combined strengths of UTEC, Acteon’s geo-services business line, Menck, Acteon’s marine foundations business line and the engineering expertise of 2H, Acteon’s engineering consultancy. During early-phase testing, we used our water-abrasive cutting tool combined with an internal lifting tool to cut and recover six piles in a single offshore operation. This allowed the operator to trial future decommissioning processes.

We supplied and operated MHU 4400S hydraulic hammers, supported by an underwater noise reduction unit (MNRU) and live penetration monitoring system to ensure efficient, safe and environmentally compliant pile installation.

For precise alignment and interface with other systems, we designed a bespoke pre-piling template. Alongside this, we installed a fully redundant real-time kinematic (RTK) positioning network, developed with a regional partner, to guide accurate pile installation across the site.

Structural monitoring systems were deployed across foundations, delivering real-time data and insight into strain, inclination, displacement, and corrosion. This coordinated approach combining our experience and advanced equipment integrated ensured safe, efficient and cost-effective delivery at scale, supporting long-term asset integrity and minimising environmental impact.

• Live depth penetration monitoring paired with GNSS-equipped hammers ensured real-time precision
• Fully autonomous RTK stations, powered by solar and remotely controlled, reduced offshore manpower needs
• NX2 digital platform integrated structural and anode monitoring data, enhancing visibility and supporting smarter O&M planning
