NDTScan provides advanced non-destructive testing (NDT) solutions tailored for deep trekker. 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 Deep Trekker remotely operated vehicles (ROVs) to conduct rapid, versatile underwater inspections of tanks, culverts, pipes, reservoirs, harbour walls, and confined marine environments. These compact, battery-powered ROVs are ideal for shallow or confined inspections where diver deployment is impractical or uneconomic.
Deep Trekker platforms allow us to deliver cost-effective, safe, and accurate underwater asset inspections across civil engineering, utilities, water management, and environmental monitoring projects.

Why We Use Deep Trekker
Deep Trekker offers rugged, reliable, and affordable subsea inspection platforms that can be deployed by small teams — enabling faster inspection, lower mobilisation costs, and high client satisfaction across marine and freshwater environments.
Other Platforms Considered
For larger offshore assets or deeper missions, we deploy Saab Seaeye ROVs. However, for portable, flexible inspections, Deep Trekker remains our go-to choice.
Versatile Underwater Inspections Without the Overhead
NDTScan’s Deep Trekker ROV systems offer an agile, responsive alternative to traditional underwater inspection methods. Whether it’s a submerged pipe in a reservoir, a damaged headwall in a culvert, or internal corrosion in a potable water tank, these compact vehicles give us immediate access without requiring divers, cranes, or large surface vessels.
For clients managing assets in the water sector, energy industry, or coastal infrastructure, this means inspection work can take place faster, more safely, and at significantly reduced cost. Deep Trekker platforms are engineered for deployment in minutes — not hours — allowing our teams to mobilise and inspect with minimal disruption to live sites, including treatment works, ports, and critical utilities.
Their battery operation and rugged waterproof construction enable us to inspect inside sealed, flooded, or remote environments where human entry is restricted or impossible. We’ve used Deep Trekker units in lock systems, weirs, submerged tunnels, outfalls, and ballast tanks — all with zero confined-space entry or specialist permits required.
Reducing Risk and Downtime Through Non-Invasive Deployment
One of the greatest advantages of compact ROV systems like Deep Trekker is their ability to operate in challenging environments without increasing risk. Our units are designed to navigate tight spaces, high-silt areas, or dark water conditions while still delivering clear HD video, sonar imagery, and auxiliary sensor readings. This non-invasive deployment approach is especially valuable when assessing ageing infrastructure that may be structurally compromised or biologically sensitive.
Where visibility is poor, sonar add-ons enable structure tracking, object detection, and feature mapping. This allows inspections to proceed in zero-visibility conditions such as turbid reservoirs or stormwater outfalls during flood events. Even when cameras can’t see, our operators can detect and evaluate structures using real-time sonar feedback — greatly enhancing the reliability and scope of underwater condition assessments.
Because Deep Trekker systems operate without external tethers or hydraulic systems, they also reduce the risk of equipment snagging or operational failure in cluttered or unknown environments. Their robust build and intuitive controls make them ideal for confined or unpredictable inspection tasks, from large-diameter sewers to culverts beneath active highways.
Intelligent Payloads for Engineering and Environmental Insight
NDTScan enhances each ROV deployment with the tools required to meet project-specific inspection objectives. Alongside visual and sonar data, we integrate auxiliary sensors and attachments to expand our inspection capabilities.
Current payload options include:
-
Ultrasonic Thickness Gauges: For underwater wall thickness verification of submerged metal surfaces
-
Cathodic Protection Probes: To test CP system function on pipelines, sheet piles, and marine structures
-
Laser Scaling Devices: To provide accurate measurements of defects, cracks, and obstructions on camera
-
Environmental Probes: Measuring pH, turbidity, oxygen levels, and temperature for ecological surveys
These options enable us to collect engineering-grade data while still operating from a compact, mobile platform. All payloads are fully compatible with the Deep Trekker DTG3 and Revolution series, allowing us to switch configurations based on project demands and access conditions.
Supporting UK Infrastructure with Reliable ROV Solutions
We support clients across a wide range of sectors with Deep Trekker ROV inspections, including:
Water Utilities and Drainage Boards: Inspection of raw water intakes, balancing tanks, storm tunnels, siphons, culverts, and non-man-entry sewers
Civil Engineering and Construction: Pre- and post-works inspection of cofferdams, quay structures, bridge piers, flood gates, and foundation piles
Ports and Harbours: Monitoring of fenders, ladders, toe scouring, mooring components, and sheet pile conditions below the waterline
Environmental and Regulatory Agencies: Non-intrusive habitat assessment, fish pass verification, sediment build-up checks, and hydroecological surveys
Each inspection is delivered with a full data package including HD video capture, annotated imagery, sensor outputs, and clear recommendations. We also provide geo-tagged reporting where possible, linking findings to drawings, site plans, or BIM models for long-term integration into asset management systems.
Portable, Battery-Powered ROVs for Confined Access Zones
Deep Trekker units are fully battery-powered, offering up to eight hours of continuous operation without generators, cables, or support craft. This makes them uniquely suited for inspections in remote, elevated, or power-restricted locations such as water treatment plants, rooftop tanks, or mobile field units.
Their lightweight build allows our teams to deploy them directly from jetties, access hatches, scaffold decks, or floating pontoons. With no surface power or hydraulic support needed, we eliminate the complexity and health and safety concerns that often accompany conventional subsea inspection systems.
Where required, our engineers can conduct inspections solo or in two-person teams — reducing costs and speeding up access approvals. This ability to deliver high-quality results with minimal personnel, logistics, or environmental disturbance is central to the value Deep Trekker offers.
Deliverables Aligned to Engineering Standards
All NDTScan ROV inspections are delivered with outputs formatted to suit engineering review and reporting frameworks. Video and sensor data are timestamped, structured, and supported by interpretive summaries prepared by experienced technicians. Where sonar is used, we include capture frames showing structure profiles, targets, and anomalies. Where auxiliary tools are deployed, we integrate data into reports alongside photographic evidence and condition commentary.
Our ROV outputs support documentation and planning under:
-
CIRIA C793 – Coastal and marine asset inspections
-
WIMES – Water Industry Mechanical and Electrical Specifications
-
BS EN ISO 9712 – NDT technician qualifications and inspection protocols
-
EA and SEPA Guidelines – Environmental condition assessment standards
We ensure our reports can be submitted directly into client systems — whether for capital planning, routine maintenance, or regulator engagement. This allows our clients to act decisively, document findings clearly, and plan future works with confidence.
Faster Response, Lower Cost, Greater Access
The Deep Trekker system’s greatest strength is its accessibility. By removing the barriers of dive teams, large vessels, and complex mobilisation, NDTScan offers ROV inspections that are deployable in days, not weeks. This agility is ideal for reactive works, emergency asset assessments, and pre-construction surveys that need to be completed quickly without impacting project timelines.
With clients increasingly seeking smarter, safer, and more sustainable solutions to infrastructure inspection, our Deep Trekker platforms provide a proven, affordable route to reliable data collection — all from a lightweight, field-ready unit.
