NDTScan uses Voyis subsea imaging systems to deliver crystal-clear underwater inspections of marine structures, pipelines, piles, and offshore platforms. Voyis is a world leader in underwater laser scanning and optical inspection, producing actionable data even in low-visibility or turbid conditions. These systems enable us to capture detailed visual and dimensional data where sonar or traditional ROV cameras fall short.
Whether assessing scour on bridge piers or inspecting quay walls, Voyis allows us to perform high-resolution NDT inspections at depth — enhancing our structural reporting in port, offshore, and coastal environments.
Continuous Innovation in Subsea Visualisation
As underwater infrastructure ages, clear imaging is vital for defect detection and condition monitoring. Voyis technology gives us the resolution needed for crack identification, biofouling assessment, and structural validation — even when silt, algae, or low light make conventional cameras ineffective.

Why We Use Voyis
Voyis is our preferred solution for projects that demand true visibility beneath the surface. Their imaging and scanning systems deliver unmatched clarity in conditions where sonar alone cannot verify integrity. This gives our clients the confidence to act on precise data rather than assumptions.
Other Tools We Use
We pair Voyis systems with ROV platforms from Deep Trekker and Blue Robotics, and in some deeper scenarios, supplement with Teledyne Marine sonar systems. However, for image-based NDT and defect mapping, Voyis is the gold standard.
Next-Generation Subsea Imaging for Critical Infrastructure
NDTScan continues to push the boundaries of underwater inspection by integrating advanced optical technologies into our survey workflows. Among the most valuable assets in our subsea toolkit are high-resolution imaging systems that go far beyond the capabilities of conventional ROV cameras. In murky, silt-heavy, or low-light waters where visibility is compromised, traditional tools often struggle to deliver meaningful results. This is where our optical inspection and laser scanning platforms shine — enabling precision imaging and dimensional analysis that support confident engineering decisions.
Clarity That Drives Better Decisions
Clear, detailed visual data is essential for detecting fatigue cracks, verifying weld quality, assessing corrosion damage, and evaluating scour or marine growth on submerged structures. We work across a range of sectors — from marine transport and coastal engineering to energy infrastructure and inland waterway maintenance — where underwater visibility is often a limiting factor in traditional non-destructive testing. Using next-generation imaging hardware, we overcome that limitation and deliver results that are not only visual but measurable, enabling dimensional verification alongside visual anomaly detection.
Modular Deployment for Diverse Environments
Our underwater imaging systems are deployed using ROVs from Deep Trekker and Blue Robotics, depending on depth, current conditions, and asset access constraints. By combining compact optical payloads with highly manoeuvrable vehicles, we carry out detailed inspections with minimal setup time, lower operational risk, and maximum visual coverage. This approach is especially valuable in ports and confined environments, where diver entry may be restricted or health and safety regulations demand remote inspection solutions.
Optical Advantage in Offshore Conditions
In offshore scenarios — such as monopile inspections, riser monitoring, or jacket foundation validation — high-quality optical data offers a layer of certainty that sonar alone cannot provide. Where sonar may outline the shape or general form of a structure, optical imaging delivers surface-level detail: weld bead condition, fine cracking, pitting, and biological encrustation. This level of clarity is invaluable for maintenance planning, anomaly logging, and compliance reporting.
Precision Laser Scanning at Depth
The integration of laser scanning into our optical systems adds a critical dimension to our surveys — geometry. Laser scanners mounted to our ROV platforms allow for high-resolution 3D profiling of submerged assets. This is particularly effective when documenting wear over time, assessing structural alignment, or quantifying material loss. On quay walls, bridge foundations, or subsea manifolds, laser data delivers sub-millimetre accuracy, enabling engineers to model repairs or evaluate tolerance breaches with confidence.
Adaptability for Confined and Turbid Environments
Because we operate in a wide range of marine and freshwater environments, adaptability is key. We deploy a mix of compact, modular imaging systems that can be configured for shallow surveys, long-duration missions, or confined space entries. This means we can work effectively in everything from estuarine silt channels and urban canals to offshore wind farms and LNG berths. Many of our optical systems include real-time lighting control and image enhancement software, ensuring usable footage even when visibility drops significantly.
From Raw Imagery to Actionable Insight
One of the major challenges in underwater inspection is ensuring that the data captured is both useful in the field and reportable in the office. Our subsea imaging workflow includes onboard processing capabilities and post-survey review software that enhances image clarity, adjusts lighting profiles, and exports 3D visualisations. This ensures that raw footage becomes actionable data — allowing condition grading, defect flagging, and historical benchmarking to support long-term asset integrity management.
Engineer-Led Visual Reporting
Our teams are trained not only in piloting inspection-class ROVs but also in interpreting visual data through an engineering lens. This means our reports don’t just include screenshots or video links — they present meaningful, defect-classified observations, dimensional analysis, and engineering insight that can be acted on immediately. When required, we integrate visual data with sonar overlays, CAD models, or BIM outputs to help clients make holistic decisions about repair, monitoring, or asset replacement.
Applications in Ports, Offshore, and Beyond
We frequently use optical imaging in the inspection of marine piles, risers, bulkheads, and fender systems, where visual damage or surface degradation needs to be clearly documented for insurance, design, or operational planning. It’s also a vital tool in emergency inspections — after vessel strikes, flooding events, or structural impact — where immediate clarity is required without risking diver access. In these time-critical scenarios, compact imaging systems deployed via ROV allow for rapid, safe, and defensible assessment.
Dual-Mode Imaging for Structural Detail
In many of our quay wall inspections, we rely on dual-mode imaging systems that combine traditional photography with laser scanning. This enables us to create a rich visual dataset, backed by accurate dimensional profiling of joint separation, face erosion, or concrete delamination. The combination of laser precision and optical clarity ensures that structural engineers, marine asset managers, and harbour authorities get exactly the data they need — without over-reliance on sonar or manual inspection alone.
Scalable Imaging Across Asset Portfolios
For clients managing multiple coastal assets — such as local authorities, port operators, or offshore developers — we offer scalable survey packages using our optical platforms. These can be deployed across multiple sites in a short timeframe, delivering consistent imaging and comparable results from structure to structure. This is particularly useful for network-wide defect tracking, condition-based maintenance planning, and lifecycle cost forecasting.
Combining Imaging with Multimodal NDT
Our visual inspection capability is also an important asset in multidisciplinary inspection campaigns. On many projects, we carry out combined sonar, laser, and optical inspections to deliver a full condition profile — from deep structure geometry to weld bead surface condition. This integration gives clients the ability to understand not only the presence of a defect but its type, location, severity, and structural impact.
Future-Proofing Our Subsea Imaging Fleet
We continue to refine and expand our subsea imaging capacity, exploring advances in AI-powered defect recognition, automated target tagging, and photogrammetry for large-scale 3D reconstructions. As optical hardware becomes smaller, smarter, and more energy-efficient, our fleet is constantly updated to ensure we remain at the forefront of remote visual inspection.
Subsea Clarity, Delivered by Experts
For any organisation responsible for submerged assets — from offshore platforms and undersea pipelines to dock walls and underwater foundations — reliable, high-resolution imaging is no longer optional. It's essential. And at NDTScan, we deliver it with precision, flexibility, and engineering confidence. Whether the goal is compliance, maintenance planning, or emergency response, our subsea imaging capability provides clarity in the most challenging underwater conditions.
