Example Operations Improvements

KeyholeTechnology

New Stopping TechnologyBig & Small

Small DiameterEMAT Sensor

• Technology enablesminimally invasive access to underground pipe and related devices

• Suite of tools and techniques for underground service and repair

• Inflatable stopping system to allow temporary stop off of gas flow

• Applied to larger diameter lines (up to 24”) and, recently, for small diameter service line abandonments

• Condition assessment of smaller diameter, difficult to assess (“unpiggable”) lines

• Uses Quest Technology’s electromagnetic acoustic tomography (EMAT) sensor

Safety: Excavation Encroachment Notification System

> Excavation causes 25% of pipeline incidents

> Technology uses GPS, motion sensors, and

communications to track construction/agricultural/other

equipment relative to GIS-based gas pipeline system

55

Safety: Emergency Remote Gas Sensing and Monitoring

> System and devices to remotely

monitor gases (e.g., methane, CO)

during emergency gas leak situations

─ Tool for utility personnel and first

responders

─ Mesh network of devices can be

placed around a home(s) or

confined space

─ Transmit real-time concentration to

give personnel rapid situational

awareness
