GDU-Incus Unit ‘Responds to the Ultrasound Produced by the Leak’

Emerson Process Management reports that the GDU-Incus ultrasonic leak detector from its Rosemount Analytical unit has received DNV type approval for marine applications.

The device is thus confirmed suitable for onboard marine vessels including liquefied natural gas and liquefied petroleum gas carriers, crude oil tankers, and floating production, storage, and offloading units, “all of which can suffer loss of production, or worse, in the event of a gas leak not being detected quickly.”

According to sales and marketing chief Eliot Sizeland, the new detector requires no gas cloud accumulation in order to sound an alarm.

Acoustic Sensing

“The GDU-Incus responds to the ultrasound produced by the leak,” he says in a release, so its performance is unaffected by extreme weather and wind. “That makes it ideal for marine applications.”

The GDU-Incus employs four sensitive acoustic sensors “that constantly monitor wide areas for ultrasound generated from the release of pressurized gas.”

Performance is unaffected by inclement weather, wind direction, leak direction or any potential gas dilution, “with an instantaneous response to methane, hydrogen, and other low molecular weight gases,” the company says.

The detector requires no calibration or replacement for the life of the instrument. “An integrated self-test ensures failsafe operation, and innovative sensors with no moving parts mitigate the need for maintenance.”
