COVER STORY
TUNNEL BORING MACHINES
INTERACTION condition monitoring systems, predictive maintenance practices
and data-driven asset management to improve equipment
reliability and minimise unplanned downtime.
As adoption of these technologies continues to grow, we intend
to leverage AI-driven diagnostics, predictive analytics and remote
equipment monitoring to optimise maintenance decisions and
maximise machine availability.
Advanced technologies such as robotic segment erection
systems, automated tail seal calibration monitoring system
and cutter monitoring systems are already demonstrating Successful operation requires continuous geological assessment,
how automation and AI can significantly improve productivity, appropriate cutter selection, optimised machine settings, effective
operational safety and equipment lifecycle performance. face pressure control and an experienced technical team
capable of responding quickly to changing ground conditions.
