Invisible but essential, the inspection of buried networks, sewerage systems or confined spaces is a strategic challenge for many public and private players. In an area like Seine-Maritime, which is highly industrialized and criss-crossed by complex networks (wastewater, industry, water or fluid transport), it is crucial to be able to regularly check the condition of infrastructures without mobilizing heavy resources or exposing personnel to risks.
This is wheretelevisual inspection (TVI) comes in. Based on the use of on-board cameras, this non-destructive method enables rapid, accurate diagnosis of inaccessible areas. In Normandy, two companies meet this demand: Alphascana specialist in on-site services, and Multinnova Normandy-based manufacturer of cutting-edge robotic solutions. Together, they cover all needs, from one-off diagnostics to the complete equipping of a facility or company.
What is a television inspection?
Televisual inspection involves inserting a motorized camera into a conduit, pipe or underground structure to observe or record the internal condition of the structure in real time. These cameras are mounted on inspection robots, capable of moving in confined, flooded, winding or small-diameter environments.
This technology can detect :
- cracks,
- pipe deformation or breakage,
- obstructions (deposits, roots, sludge),
- joint defects or infiltrations,
- incorrect connections.
The images captured serve as the basis for a standardized report, compliant with NF EN 13508-2, with coding of anomalies and recommendations for action.
A reliable, safe and cost-effective method
ITV has become the standard for preventive inspection. Unlike destructive methods, it involves no digging, dismantling or service interruptions. It reduces maintenance costs while minimizing risks for operators.
What's more, it offers complete traceability, with time-stamped recording of videos and technical data that can be used for audits or expert appraisals.
A variety of uses in Seine-Maritime
In Seine-Maritime, ITV inspections are used by :
- local authorities for wastewater and stormwater network diagnostics,
- industrial companies to monitor pipes, ducts and tanks,
- port or petrochemical operators to monitor buried or flooded networks,
- design offices for site supervision or diagnostics prior to work.
Alphascan: turnkey ITV services
Based in Normandy, France, Alphascan specializes in customized television inspection services. It operates directly in the field on behalf of local authorities, public works companies, sewerage associations and industrial companies, on one-off assignments or long-term maintenance contracts.
Expertise in the field to enhance performance
The Alphascan team is made up of trained and certified technicians, accustomed to working in complex environments. It has access to the most modern equipment, including robots designed by Multinnovsuch as :
- the Roview2 for submerged or complex pipelines,
- the Stereo2an indoor drone for inspecting structures at height or in confined spaces.
Alphascan adapts its interventions to each situation: difficult access, wet environments, emergency after disaster, or planned maintenance programs.
A rigorous intervention method
The services are provided in several stages:
- Study of needs and technical constraints ;
- Selection of robot and appropriate accessories (wheels, floats, pole, etc.) ;
- Inspection and high-definition video capture;
- Anomaly analysis according to ITV ;
- Detailed report with recommendations for action.
This process guarantees complete traceability, a clear reading of defects, and reliable recommendations for maintenance or rehabilitation.
Local responsiveness and a relationship of trust
Based in Normandy, Alphascan can intervene rapidly in the Seine-Maritime region, which is a major advantage in the event of an emergency (breakage, collapse, flooding...). Our approach is based on proximity, transparency and a clear understanding of our customers' technical and budgetary issues.
Multinnov: technological innovation made in France
Alphascan is in the field thanks to tools designed by Multinnova Normandy-based company specializing in robotic inspection systems for confined spaces. Multinnov designs, assembles and distributes new-generation robots and drones for ITV professionals, design offices, operators and manufacturers.
Roview2: an all-terrain inspection robot
The Roview2 is a compact, amphibious robot with a steerable 4K camera, ultra-powerful LED lighting, wireless transmission and a 500-meter range. It can operate in :
- flooded or dry pipes,
- winding or steeply sloping networks,
- small and medium-diameter structures.
It complies with ITV requirements and can be easily integrated into the workflows of design offices and technical departments.
Stereo2: the indoor drone for complex structures
The Stereo2 is an indoor inspection drone, designed for industrial chimneys, silos, structures or engineering works. It can fly without GPS, stabilizes automatically in lightless environments, and transmits 4K video in real time.
These two tools enable users towork without a cherry picker, scaffolding or dismantling, in unrivalled conditions of safety and speed.
Multinnov: more than just a manufacturer
Multinnov also supports its customers through :
- training in robot handling,
- after-sales service based in France,
- adaptable accessories (wheels, lighting, tracking modules),
- a rationale of technological sovereignty, with mostly local production.
Investing in Multinnov equipment means choosing performance, autonomy and local support.
Today, television inspection is an essential tool for guaranteeing the safety, compliance and durability of buried or confined networks. In the Seine-Maritime region, two Norman players stand out for their complementary skills:
- AlphascanAlphascan, a company that carries out inspections in the field with efficiency and responsiveness;
- Multinnovwhich designs and manufactures robust, innovative inspection robots and drones adapted to the realities of the field.
Whether you're a local authority, an industrial company, a network manager or a design office, you can count on these two partners to carry out your diagnostics, gain technical autonomy and anticipate failures.
When you choose a Normandy-based company for your ITV inspections, you're opting for made in France, proximity, and a high level of expertise at the service of your infrastructures.
