Discover our technology

the challenge

Buried pipelines are the most secure and efficient means to transport vital resources, water and energy. Precise localization of such critical infrastructure is essential to ensure integrity. SKIPPER NDT’s localization solutions are precise and cost-efficient for protecting pipelines from third party damage and for identifying pipeline movement on unstable slopes.

SKIPPER NDT carries out pipeline mapping using a UAV equipped with sensors and proprietary algorithms for data analysis


SKIPPER NDT’s solution is based on contactless magnetic technology with an automatic data processing protocol. The result is precise localization without interfering with operation of the pipeline.

Safety of field operators

The technology allows difficult terrain to be accessed without exposing operators to hazards in the field. Magnetic data on pipelines are obtained remotely using a drone.

Protection of the environment

Over 10 years, third party damage on US gas networks caused 363 fatalities, 1,392 injuries and $800 Billion in material damage.

Budget Optimization

Besides superior performance, SKIPPER NDT’s solutions are cost competitive due to the speed of data acquisition and ease of implementation.



Localization of water pipelines prevents third party damage that can result from a lack of precise geographic information


Pipeline localization is of concern to regulators. In France, localization of critical pipeline networks is mandated by law


SKIPPER NDT’s solution provides high precision cartography, allowing any ferromagnetic object in the soil to be identified. This is of particular interest at pipeline construction sites

solutions vectors

SKIPPER NDT’s technology is deployed in the field using one of the following types of equipment


A standard drone coupled to a bar equipped with magnetic sensors and an electronic card with embedded data processing algorithms

ground-based mobile equipment

A field machine that can be pushed by an operator or towed by a 4X4 vehicle



In some countries, mapping of buried pipelines is mandated by the regulator. Mapping is also necessary to avoid third party damage and to track a pipeline in unstable slopes.

In the event of a break in a water pipe, there is a risk that powerful jets of water could lead to some elements (fragments of pipes or fittings) becoming projectiles.  A water pipe break could also lead to flooding near ​​the site of the break and beyond, as well as scouring, destruction, etc…


Water and energy pipes are subject to damage by third-party work, often due to poor geolocation. The SKIPPER NDT solution for georeferencing pipelines offers proven advantages in terms of operator safety, accuracy and cost. SKIPPER NDT’s continuous R&D efforts help improve performance and expand the scope of applications.
