PipeInspection
Optical fiber spool production for wire-guided robots
SEDI-ATI offers disposable ultra-lightweight and compact fiber optic spools directly mounted onto tethered robotic crawlers for pipe inspection operations.
MajorConstraints
- Immersion in different types of liquids (sewed water, mud…),
- Mechanical strains (shocks, vibrations, radius of curvature),
- Allow both video and monitoring signals over long distances inside pipes.
TheChallenge
Need for real time data and live video feed over long distances inside pipes, where no radio frequency waves (RF signals) can pass.
Dangerous practices for humans and the environment
Previously carried out by humans, these pipe inspections directly exposed them to the material and human dangers associated with potential leaks or spills that could lead to injury or even death. In view of these well-known and disastrous risks, in both human and environmental terms, it was more than necessary to deploy new means of limiting human intervention: creating fiber-optic-powered pipe inspection robots.
Replacing electronics with fiber optics
To meet the need for real-time data and live video feed over long distances inside pipes, where no radio frequency waves (RF signals) can pass, the spool directly integrated into the robot can be deployed over 10km, providing high bandwidth for a large and constant data transfer, overcoming sealing or mechanical constraints.
SEDI-ATISolution
We offer a disposable ultra-lightweight fiber optic cable, directly mounted onto the tethered robotic crawler.
It is the robot that deploys the optical cable by traveling through the pipe.
Therefore, there is no traction nor any other mechanical force applied on the optical fiber. We can design spools / tapes with different optical fiber lengths, depending on the distance to be travelled.
AdvantagesOf the SEDI-ATI solution
- The spool of fiber optic is directly integrated into the robot,
- Ease of installation on the robot,
- Travel distances up to 10 km from the launch point,
- Broad bandwidth for huge/heavy data transfer,
- The fiber optic cable can be left in the field to free the robot: no need to make the return trip, no risk of fibre entanglement.
