TBM View – Real-Time Continuous TBM Parameters Trend Monitoring

Summary

Current TBM Monitoring systems are set to respond to settlement monitoring results that are, at best, reported the next day. If something is really wrong then it is too late.

TBMView system can show trends and highlight errors and over excavation as it is happening and whilst there is still a chance to avoid the settlements.

With TBMView innovative approach one can:

– Monitor excavation weights per ring in real-time.
– Have insight into chamber fill material without camera.
– See if you are working under pressure by the EPB TBM cell responses during ring build.
– See grout pressures and volumes as the shield advances.
– See correlated thrusts forces and navigation parameters while advancing

To this end TBMView approach implements a layer of context sensitive high performance monitoring system, where correlated events are captured, filtered, grouped and analysed in real-time and within context of the relevant target parameters.

All TBM parameter values are equipped with a traffic-light colour-coded event and alarm triggering mechanism providing an at-a-glance fashion comparison with TBM targeted values and thresholds, enabling rapid decision making.

In short the main benefit of real time trend monitoring of TBM parameters is that Management can see and react to what is going on in real time, before it is too late.
