As one of the fastest-growing energy products on the market today, liquid natural gas (LNG) presents unique challenges for the industry. With both production and transport facilities moving further offshore, there is pressing need for a safe, efficient and reliable transfer system.

Monitoring and instrumentation play a vital role in this system. By enhancing safety and security of cryogenic materials in a subsea environment, they boost productivity while drastically reducing the risk of costly leaks.

The fiber-optic advantage: leak detection in mere seconds
But while it is critical to monitor for anomalies, leaks and temperature along LNG pipelines, not all monitoring is the same. Our fiber-optic sensors provide real-time, highly accurate strain, temperature, vibration, and flow monitoring. They surpass other technology because of their multiplexing capability, immunity to electro-magnetic interference, ruggedness and long-distance signal transmission ability.

Our system is at the cutting edge of both speed and accuracy. It will identify a leak within 2 seconds and the precise location of a leak within two minutes. In addition, our sensors provide crucial information about equipment conditions at startup and shutdown without any penetration of the pipeline.

And our technology has a proven track record. Astro Technology successfully instrumented an insulated subsea flowline bundle in a deepwater Gulf of Mexico facility in 2007. Additional testing, in collaboration with NASA, has verified the effectiveness of fiber-optic sensors for leak detection in oil and gas pipelines, further illustrating the importance of this technology. We continue to refine our monitoring of LNG pipelines as the market grows and puts ever-increasing pressure on production and transportation.
