Optimising Costs from a Stable Base
SETTING THE STANDARD IN PIPELINE MANAGEMENT
Fibre optic monitoring
Technology selected
Other pipeline management
Pressure cycles to estimate fatigue
OptaSense®
a QinetiQ company
Water pH control optimisation
Implementation by March 2020
PIG runs
Internal scan of pipeline integrity
Every 2 years, ~2Mt impact (1 month production)
Less frequent water batches
Previously pumping was focused on slurry quality,
now also focused on pumping pressure
Consistent pressure important for integrity
Monitoring & assessment of corrosion
New reagents to sequester oxygen
Interconnected operation without surge tank
Mapping slopes, tunnels & containment structures
Revised pump design to improve availability &
reliability
External coating & cathodic protection inspection
