Natural Gas Pipelines: Is There A Safer Alternative?

Natural Gas Pipelines: Is There A Safer Alternative?

Natural gas pipelines have caused incidents leading to fatalities, injuries, and property damages.

To be precise, there have been an average of 50 serious gas pipeline incidents every year in the U.S. between 1990-2009 (Source: http://primis.phmsa.dot.gov/comm/reports/safety/SerPSI.html?nocache=4823) resulting in more than 300 fatalities. Majority of the reported gas incidents have occurred on the gas distribution lines – i.e.  gas pipeline systems that are found in thousands of communities from coast to coast and distribute natural gas to our homes and businesses.

It is almost a guarantee that you will hear about gas pipeline incidents in 2010.

Earlier, I have addressed the major causes of pipeline failures. Here I want to raise a different questions which no one appears to be discussing – is there a safer alternative to gas pipelines? 

The most common uses of gas coming into homes are cooking and heating. When I lived in New Hampshire my place was heated by gas.  Granted heating homes via gas is cheaper but the electric heating poses lower risks.

I can envision one option as having gas cylinders instead of gas pipeline at least for cooking.

There are many places in the world that utilize LPG cylinders as opposed to gas pipelines. If you think about it going to gas cylinders from a pipeline, you have applied inherently safer strategies:Minimize : Use small quantities of hazardous substancesModerate: Use less hazardous conditions, a less hazardous form of a material,or facilities, which minimize the impact of a release of hazardous material or energySimplify: Design facilities which eliminate unnecessary complexity and make operating errors less likely

If I extend the logic further, one can argue local storage hubs for supplying gas to heat homes and it will still fall in the realm of inherently safer philosophy.  

Gas cylinders have two additional benefits  (a) distributed energy system and therefore lower vulnerability (b) reduced risks of intentional attack

So…what are the arguments in favor of gas pipelines? Does the benefit of low-cost gas heating justify the risks from gas pipelines?

Is the fact that the gas pipeline infrastructure has been developed and already exists, a sufficient reason for Office of Pipeline Safety to keep collecting incident data?

Concluding Thoughts

In the last couple of years, there has been considerable interest in introducing inherently safer alternatives in chemical facilities. There has been debate about mandating inherent safety. As you think through inherent safety issues and take them to a logical conclusion, you will see how a given non-inherently safer approach  also brings benefits. In applying inherent safety principles may not be a trivial exercise for existing facilities and infrastructure.

But what about new facilities and infrastructure – is there an inherently safer alternative for new gas pipelines? Any thoughts?

About Sanjeev Saraf

Reduce risks, Increase Uptime, Reduce costs

I did my first litigation support work in 2000.

Since then I have been obsessed with preventing future failures. Some of these failures can have catastrophic consequences.

Having tried various techniques, learning / unlearning “latest” paradigms, it is clear we have a long way to go!

But instead of thoughtful work, what I mostly see are platitudes and oversimplifications. No keen practical insights!

I want to change that.

    beneficial but it is very dangerous, almost most of the pipelines are undergrounding in urban area where population is much crowd and in todays most of the optical fibre cables are also undergrounding due to that project sometimes they damages the gas pipeline….
