SoCalGas Breaks Ground on Innovative Fiber Optic Installation to Monitor
Pipelines in Real-Time
Early warning sensors will help prevent pipeline damage from
unauthorized construction work and detect leaks.
Dec 13, 2017
LOS ANGELES, Dec. 13, 2017 /PRNewswire/ -- Southern California Gas Co.
(SoCalGas) today announced it has broken ground on a first-of-its kind, fiber
optic cable installation that will allow the company to monitor the condition
of its high-pressure transmission pipelines in real-time. The fiber optic
technology is being installed along a new, seven-mile section of natural gas
pipeline in Bakersfield, California and will serve as an early warning system
to detect unauthorized construction work that could damage the pipeline and
changes in pressure in the line that could indicate a leak. Photos of the
technology from today's installation are available here.
"SoCalGas is committed to modernizing our infrastructure to enhance
safety for our customers and reduce our carbon footprint," said Deanna
Haines, director of gas engineering for SoCalGas. "This technology
provides our engineers with a critical early warning system that can prevent
damage to our lines and help us mitigate leaks more quickly."
"Having real-time information on the status of high-pressure
pipelines is critical in the early detection of a potential problem," said
Brian Marshall, Kern County Fire Chief. "Firefighters will be able to
respond quickly to an emergency and work with SoCal Gas to stop the problem
from escalating."
The technology uses fiber optic cables that run along a pipeline and
that transmit data across long distances. The system operates on the principle
that light signals vary when a fiber optic cable is exposed to vibration, stress,
or abnormal changes in temperature – all indicators of a possible natural gas
leak or an impact to a natural gas line. The fiber optic system can pinpoint
within 20 feet where a potential problem may be developing.
When a threat is detected, information is sent along the fiber cable to
a remote monitoring station within seconds, where operators interpret signal
changes to determine the source of potential intrusions including, heavy
equipment operation, unexpected earth movement, or other physical impacts like
structural stress from broken water mains.
Access to continuous, real-time measurements and area-specific data can
give SoCalGas crews and first responders more time to plan, allocate resources,
and take effective actions to mitigate potential leaks and damage to pipelines.
SoCalGas is one of the first natural gas utilities in the country to use
the technology in natural gas transmission and high-pressure pipeline system
operations. The company plans to install fiber optic cable along all new and
replacement pipeline segments 12 inches and greater in diameter and one-mile
long.
Incorporating fiber optics into its transmission pipeline and
distribution systems is part of SoCalGas' commitment to upgrading and
modernizing its more than 101,000 miles of natural gas pipelines in order to
provide customers with the safe, reliable, and affordable energy they deserve.
