Offshore inspection
Acteon delivers specialist offshore inspection solutions that help energy operators protect critical infrastructure, meet regulatory requirements and extend asset life.
From subsea inspection to mooring chain condition monitoring, we help operators reduce offshore risk, meet compliance standards and extend asset life. Our offshore inspection services support structural integrity across a range of operations - including geophysical surveys, digital data capture and rapid mooring inspection following unplanned events.
Highly qualified offshore personnel with strong expertise in all subsea acoustic technologies and data acquisition packages.
Acting on clarity and confidence offshore
Our offshore inspection services deliver high-resolution data on structural condition, corrosion and mooring systems. These insights support smarter planning, reduce emergency interventions and protect long-term offshore asset integrity.
Preventing failures and responding fast
Our integrated subsea inspection and mooring chain inspection services identify potential issues before they escalate. Where urgent intervention is needed, we respond efficiently to reduce downtime and maintain safety.
Staying compliant at every lifecycle stage
We support inspection schedules aligned with regulatory frameworks, from baseline surveys to late-life assessments. This ensures critical infrastructure, including moorings, remains compliant and operational throughout the asset lifecycle.
Making smarter, risk-informed decisions
Real-time inspection data, combined with domain expertise, supports better decision-making. Operators gain the insight needed to prioritise maintenance and reduce offshore exposure across critical marine infrastructure.
Subsea inspection
Providing clarity and confidence, below the surface
Our subsea inspection services deliver reliable, high-resolution data on structural condition, corrosion and marine growth, giving operators and asset owners the insight they need to act decisively. We deploy Class II and III ROVs equipped with 3D photogrammetry, ultrasonic thickness (UT) measurement, cathodic protection (CP) sensors and acoustic imaging systems to assess asset integrity in real time. Our teams support both planned and reactive campaigns, helping to reduce unplanned outages, maintain compliance and inform maintenance decisions. With deep technical expertise and a flexible delivery model, we provide clarity beneath the surface, wherever and whenever it’s needed.
Geophysical survey
Mapping the unseen to protect what matters
Our geophysical surveys deliver high-resolution mapping and subsurface characterisation to support safe, efficient offshore operations. Using a range of sensors - including side-scan sonar, sub-bottom profilers, magnetometers and multibeam echosounders - we provide detailed insight into seabed conditions, buried infrastructure and potential hazards. This data underpins everything from baseline assessment to late-life decommissioning planning. With over 50 inspection surveys completed globally, we help customers reduce risk, optimise inspection and intervention campaigns, and make confident, informed decisions. Our expert teams and partner-orientated approach ensure geophysical insights translate directly into operational value.
Our technology
iSite is Acteon’s digital platform for storing, visualising and analysing offshore inspection and survey data. It gives operators on-demand access to integrated datasets - helping them plan smarter, respond faster and reduce the need for offshore personnel across the asset lifecycle.

Digital data management
Turning inspection data into actionable insight
Acteon’s digital data solutions give operators secure, 24/7 access to inspection and survey data, wherever and whenever they need it. By centralising data across campaigns, assets and lifecycle stages, we support more strategic maintenance planning, reduces the need for offshore personnel and helping ensure regulatory compliance. With built-in visualisation and reporting tools, we simplify decision-making and improve transparency across teams.
Our technology
iSite brings together inspection, monitoring and survey data in one platform. Designed for offshore asset integrity, it helps teams track trends, flag anomalies and generate reports, all without needing to mobilise. It’s this reliable, digital visibility that drives better offshore outcomes.

Rapid response survey
Ready when our customers need us most
When the unexpected happens offshore, timing matters. Acteon’s rapid response teams are ready to deploy - combining experienced personnel, standardised processes and portable technology to deliver fast, effective inspection and survey support. From mooring failures and subsea anomalies to urgent compliance checks, we help minimise downtime and restore operational integrity safely. With rapid mobilisation and access to real-time data via iSite, our customers gain the visibility and control they need to act with confidence, even in the most time-critical situations.
