Distribution Gas System Operators
• Senior Gas System Coordinator • Gas System Coordinator • Gas System Operator
Gas Control Room Roles
• Senior Distribution Gas System Operator • Distribution Gas System Operator
Transmission Distribution
• The structure of our control room is designed with efficiency in mind
• Transmission and Distribution operators are located on the North and South sides of the control center
• Gas leadership and Clearance Coordinators are situated in the back of the operation
• Communications Specialists and Planning Engineers are centrally
located between transmission and distribution to provide support
Control Room Structure
New Control Room Training Philosophy
Golden Rules:
• Operate the Pipeline Safely (Know your MAOPs) • Meet Minimum Pressures • Make Scheduled Rates (Volumes) • Operate System Efficiently
New Control Room Training Philosophy
“We need a training program for the operators, by the
operators…”
New Control Room Training Philosophy
Regimented Learning Objectives • Gas Basics and Fundamentals • Built with Operator Qualified Control Room Personnel, Engineering and
Maintenance Experts • Geographic-based Gas Operations System training • Operational Controls Philosophy • Alarm Philosophy and Management • Console specific role and responsibility focused • Gas system oriented training for normal, abnormal, and emergency
operating conditions • Certified Technical Trainers (CTT+) deliver instructor led training

Leak and Alarm Scenario #1 Severe line rupture near Monroe, not sure which side.
1. Multiple SCADA Lo Lo alarms could occur: • Adobe = 250 psig (one alarm) • Cotati = 230 psig (one alarm) • Monroe = 200 psig (4 alarms) • Madrone = 230 psig (6 alarms) • Santa Rosa Compressor = 195 psig (2 alarms)
3. Multiple RCV alarms occur: • V-16, V-51.41, V-8 alarm at
160 psig and/or -10 psi/min. • Six RCV alarms at Madrone
might also be received. Alarm Alarm
2a. The flow meter at SR compressor should indicate whether the leak is U/S or D/S of the compressor station.
2b. Nearest U/S flow meters are at Adobe: • M-1 on16” L-21D Hi Hi = 2.7 MMSCFH. • M-3 on l2” L-21C Hi Hi = 2.7 MMSCFH.
2c. College Ave flow alarm not configured.

• Provides situational awareness to anyone who walks in Control Room • Shows where focus should be concentrated in event of an emergency
• Complete overview/snapshot of our system
Video Wall
• Gas Control upgraded SCADA system from Citect to Telvent based on the CFR 192.631 CRM to incorporate API 1165 “Recommended Practice for Pipeline SCADA Displays”.
• Using grayscale background, clear images for common objects and actions, and color only when necessary, the displays provide high level of situational awareness.
• Benefits of upgrading the SCADA systems provides a higher level of safety by providing better situational awareness and improving operational efficiency
