Nearshore construction

Act on coastal complexity

We support nearshore construction across LNG, mining, ports and marine infrastructure. From terminals and bridges to aquaculture and harbour developments, our engineering-led solutions help deliver critical assets safely, efficiently and with reduced cost. We apply deep technical knowledge and practical experience to develop tailored installation methods that improve constructability, reduce offshore time and control total expenditure.

Supporting the LNG, port infrastructure and mining industries for decades

We provide fully integrated pile installation services, including design engineering, piling templates, lifting and handling equipment, relief drilling, socketing, drive-drill-drive and structural grouting. With decades of expertise in cluster and XL monopile installation, we help customers deliver on schedule, even in remote or technically demanding environments.

Acting on complexity in nearshore environments

Understanding ground conditions

We reduce ground risk through integrated geotechnical and structural design services. Using the latest tools and techniques, we deliver high-quality data and insight into subsurface conditions – supporting more efficient, lower-risk foundation design.

Act on Energy - Episode two

In this episode of our Act on Energy podcast, Tim Eyles, VP at Acteon, alongside Christopher Hillier, Head of Sales and Commercial and Greg Hammond, EA Digital Lead at UTEC, Acteon’s Geo-services business line, explore how offshore operators can extract more value from the vast amounts of survey and inspection data collected in the field and how good data structure lays the foundations for smarter, faster decision-making, including future AI applications.

Site investigation and characterisation: Why early offshore seabed mapping is critical for project success?

Every offshore project begins with one critical step: understanding what lies beneath the seabed. But when decisions are based on incomplete or low-resolution data, the consequences can be costly. While construction planning and foundation procurement are often prioritised, early marine surveying is too often scoped as an afterthought.

The cost of inaccuracy: why dimensional control surveys matter offshore

Precision offshore isn’t optional - it’s essential. In environments where every millimetre counts, Dimensional Control (DC) surveys are a critical safeguard against costly mistakes. Yet, they’re still too often seen as a discretionary step rather than a core part of project planning. It’s time to change that perception.
