SCADA Systems in the Pipeline IndustrySHANE AYERS

Failure saves lives. In the airline industry, every time a plane crashes the probability of the next crash is lowered by that. The Titanic saved lives because we're building bigger and bigger ships. So these people died, but we have effectively improved the safety of the system, and nothing failed in vain.

- Nassim Nicholas Taleb

Why wait for one failure to lower the probability of the next?

Supervisory Control And Data Acquisition (“SCADA”) Systems can play a role in operating a safe pipeline.

SCADA… Safety, or Illusion of Safety?

Theoretically, SCADA can Save lives

Reduce impact of catastrophic failure

Control room management regulations

Integrity Management Program (“IMP”) 2.0

Operator Qualification (“OQ”)

The need for more robust, and more stringent training and qualifications of individuals installing, troubleshooting, repairing and operating SCADA systems, can public safety be impacted in a positive way.

Regulations

Control Room Management regulations were “Controversial”

OQ regulations were “Controversial”

IMP regulations were “Controversial”

Safety Management Systems like the ones in place in the airline and nuclear industries are now “Controversial”

Why?

Current Regulations are the Minimum requirement

Negotiated Rulemaking

OQ mandate in 1992 Rule became effective in 1999

Control Room Regulations Rule became effective in 2011

Issues still exist… Non-existing or ineffective training

Failure to identify abnormal operating conditions

VGOA Involvement

• Regulator and Utility company executive Committee was formed to address common issues such as OQ (Began in June 2011)

• This committee worked with the Virginia Gas Operator’s Association to address industry issues proactively

• All agreed that existing training and OQ plans needed to be improved

• SCADA was not identified as an area needed because it was not in the existing “covered task” lists

Results of Enhanced Construction OQ in Virginia

Initially, with enhanced construction modules, failure rate for previously “qualified individuals” was approximately 60%

Individuals who passed were proud of the accomplishment

3 strike / 6 month lock out policy hit home

Enhanced training has already mitigated 1,000s of documented issues

Feedback from field employees is that OQ is no longer a “joke”

Do Industry Employees believe more stringent procedures, rules and regulations are required regarding SCADA?

Yes; 92%

No; 1%

Somewhat; 7%

Why do Industry Employees believe someone might choose not to report an issue (not following existing procedures, rules and regulations)?

Man-agement

Would not Take Action; 16%

Fear of Enforcement by Regulator; 25%

Not my Business; 7%

Negative Impact to Coworker, 52%

How do Industry Employees believe training and qualification programs can be improved?

More Training; 10%

Better Quality Train-ing; 62%

More Oversight; 4%

Reward and

Penalty Pro-

grams 12%

Remind of Nega-

tive Conse-

quences; 13%

Software is Just Software

Pressing a button isn’t the same thing as turning a valve

Software systems can be managed by anyone, anywhere

Outsourcing / offshoring saves money and lowers rates

Nothing Is Wrong With the Way We Were Doing Things

People could be quickly qualified and put to work in their field

Very few accidents compared to other industries of transportation

Training programs already complied with regulations

SCADA Doesn’t Fit the OQ Rule Requirements, Right? Four Part Criteria

Control room software and communication systems are not technically connected directly to pipelines, so they are exempt from OQ

Only the Technicians that install mechanical equipment connecting to pipelines should be qualified

OQ wasn’t needed for SCADA before, why now?

It Will Take Too Long to Re-Train, and That Costs Money!

Not enough trainers

literacy concerns for field only personnel

Unions

Lock out rule is unfair

Whole process is time consuming to implement

Why cant contractors self administer testing?

Conclusion

People currently working in the industry overwhelmingly agree the quality of existing training programs should be improved

A better trained workforce can make better and safer decisions

Control room employees operating SCADA must have the same knowledge of systems they control as employees who physically control them in the field

Control Rooms must be updated and comprehensive

OQ must extend to SCADA as a covered task and modules be developed and implemented
