NDTScan provides advanced non-destructive testing (NDT) solutions tailored for teledyne marine. Our services ensure accurate, compliant, and efficient diagnostics across all sectors, from aerospace to infrastructure. With cutting-edge equipment and over a decade of experience, we deliver certified inspections that minimise downtime and maximise safety. Trust NDTScan for reliable, data-driven reporting that enhances your decision-making and operational excellence.
NDTScan uses Teledyne Marine systems to support complex underwater surveys, sonar imaging, and long-range data capture for offshore infrastructure, pipelines, port assets, and seabed features. With advanced multibeam, side-scan, and profiling sonar systems, Teledyne is trusted globally for delivering clear subsea intelligence in high-pressure environments.
We use Teledyne for deepwater inspection, scour analysis, bathymetry, and high-accuracy sonar-based structural mapping.
Continuous Innovation in Subsea Sensing
When visibility fails and depth increases, Teledyne Marine systems provide sonar-based clarity. Their imaging systems reveal defects, movement, and seabed changes critical to asset integrity and environmental compliance.

Why We Use Teledyne Marine
Teledyne provides sonar clarity where vision ends. Their systems help us deliver detailed seabed and structure data in demanding marine environments where visual tools fail.
Other Tools in Use
We use Voyis for underwater camera work, but for sonar-based inspection and acoustic imaging, Teledyne Marine is unmatched.
Subsea Intelligence for Critical Infrastructure
At NDTScan, underwater inspection is not an afterthought — it’s a core discipline. We specialise in high-resolution sonar-based surveys that deliver critical data from below the waterline, where visibility is limited, conditions are challenging, and the margin for error is razor-thin.
Our subsea operations support asset integrity management across offshore wind, oil and gas, coastal defence, ports, harbours, and inland waterways. Whether inspecting anchor piles at 60 metres depth or mapping scour around bridge piers, we use cutting-edge acoustic systems to reveal what the human eye can’t see.
Why Acoustic Imaging Matters
Underwater environments present a unique set of challenges for operators of Teledyne Marine equipment. Turbidity, currents, low light, and biofouling often render traditional video and diver inspections ineffective. That’s where sonar imaging comes in. Using high-frequency sound pulses, we generate real-time images and 3D models of underwater structures, terrain, and anomalies — even in zero-visibility conditions.
Sonar doesn’t just provide pictures; it gives precise, quantifiable measurements — depth, shape, movement, deformation — all of which are essential for engineering assessments and compliance reporting.
Real-World Applications of Sonar-Based Inspection
1. Offshore Wind Foundations
We inspect monopiles, transition pieces, and scour protection systems for signs of fatigue, movement, or seabed erosion. Our Teledyne Marine sonar units can detect early-stage anomalies such as micro-scour or vertical misalignment — helping operators avoid failure, downtime, or rework.
2. Pipeline and Riser Surveys
Subsea pipelines are vulnerable to lateral movement, free spans, and support degradation. We use acoustic profiling and high-frequency scanning to inspect hundreds of metres per mission, identifying critical defects without diver intervention.
3. Port and Harbour Asset Management
Marine infrastructure like quay walls, fenders, dolphins, and mooring systems require regular assessment. Sonar imaging detects voids, marine growth, displaced rock armour, or undercutting long before visible symptoms emerge.
4. Scour Analysis for Bridges and Piers
Water flow around bridge piers or causeways often leads to foundation scour — one of the leading causes of structural failure in civil infrastructure. We map the seabed profile and sediment levels to quantify risk and track changes over time.
5. Emergency Response and Hazard Detection
In the wake of vessel strikes, flooding, or structural collapse, sonar provides fast, accurate visuals of the submerged scene. This data is vital for decision-making, salvage planning, or legal documentation.
Integrated Subsea Workflows
Our underwater survey platform doesn’t operate in isolation. We integrate sonar data into wider geospatial and structural models using BIM and GIS-compatible formats. This allows engineers, designers, and asset owners to interact with underwater data as part of a unified digital twin — streamlining asset management and long-term planning.
Using acoustic modems and remote-control interfaces, we can operate in fully autonomous modes when required — ideal for hazardous, remote, or time-critical inspections.

Teledyne Marine Team Expertise and Deployment
All underwater Teledyne Marine inspection activities are conducted by experienced NDTScan technicians trained in hydrographic survey standards and offshore operational safety. Our teams include certified sonar analysts, marine engineers, and ROV pilots, capable of mobilising anywhere across the UK or internationally.
We also work with accredited marine consultants and ecologists where environmental sensitivity or protected habitats are involved, ensuring surveys are both technically compliant and ecologically responsible.
Tooling and Platform Versatility
While we rely on sonar systems for acoustic imaging, our full subsea platform includes:
-
ROVs and AUVs: Remote vehicles fitted with scanning, video, and navigation packages.
-
Drop Cameras and Diver Video: Used where visual confirmation is possible or preferred.
-
Acoustic Modems: For real-time data transmission during deepwater or tether-free missions.
-
Bathymetric LIDAR (for shallow water transitions): Captures above- and below-water elevation data in one pass.
This flexibility allows us to tailor our inspection setup to your site, water depth, environmental risk, and data requirements — ensuring you get maximum value with minimal on-site time.
Supporting Sustainable Marine Operations
Accurate underwater inspection supports sustainability. By detecting early-stage wear or environmental change, our sonar data helps operators extend the life of marine infrastructure, reduce reactive maintenance, and avoid disruptive emergency interventions.
We also support environmental monitoring with Teledyne Marine — mapping sediment transport, identifying debris fields, or assessing fish habitats — contributing to responsible marine development and coastal resilience planning.
The Bottom Line
Whether you manage an offshore platform, a ferry terminal, or a tidal barrage, what happens beneath the waterline is mission-critical. Our underwater inspection services provide the sonar clarity needed to keep marine infrastructure safe, compliant, and operational.
We don’t rely on guesswork or grainy video. Our systems produce measurable, repeatable data that stands up to engineering review, insurance scrutiny, and environmental compliance.
With NDTScan, you get a partner who understands the complexity of underwater structures — and with Teledyne Marine equipment delivers the data you need to manage them effectively.
