In-line inspection
Smart pigging for wall-loss, geometry and crack detection.
Midstream
Corridor development and long-term asset reliability
An end-to-end infrastructure profile covering conceptual routing, construction, monitoring, integrity, maintenance and rehabilitation.
Delivery scope
- Construction of trunk lines and gathering systems in challenging terrain.
- Horizontal directional drilling and non-destructive testing to protect quality and reduce environmental impact.
- Integrity management through in-line inspection, cathodic protection and continuous monitoring.
- Repair and rehabilitation measures that extend the operational life of existing assets.
Integrity methods
Sustaining transport reliability over the asset life cycle
Cathodic protection
External corrosion control on buried and submerged pipe.
Continuous monitoring
Round-the-clock surveillance of pressure and flow continuity.
