Advanced Leak Detection on LNG Vessels: HERTZINNO HZ-HA-170P Performance on A LNG & HA3LX Evolution

1. LNG Carrier Operations and the Imperative for Precision Leak Detection

Modern LNG carriers like ****** navigate complex operational landscapes where cargo integrity directly impacts safety and profitability.
Handling cryogenic methane, ethane, and propane requires systems capable of identifying minute leaks within high-noise environments. Traditional methods often fail to localize leaks efficiently, especially during active operations with machinery running at 100+ dB noise levels.

2. Field-Validated Performance: HERTZINNO HZ-HA-170P (Gen 2 Pro)

The December 4th testing aboard the LNG utilized our HZ-HA-170P Professional Edition featuring:

• 138-element phased array for superior spatial resolution
• ATEX IIB T4 certification for explosive gas environments
• 200 kHz sampling rate capturing ultrasonic signatures 

Butane (CCR calibration):
During the test the gas flow was kept in different direction - See below

Propane (cargo system)

The second test was made on leak prepared on cargo (propane) installation – slightly stronger than human breath – see below.
Cargo compressor was running in the gas plant during the test.

The leak at cargo system detected by HERTZINNO acoustic camera. 

Cargo (propane) leak detected from different side.

Third test was carried out on two vales of cascade freon system. Upper or lower valve was leaking – HERTZINNO without mistakes detected leaks.

Freon upper valve’s leaking and detection mark of HERTZINNO, and the same leak detected from longer distance:

The leak detected at lower freon valve from distance around 1.5 m

Fourth test was prepared at compressed air in engine room at aux. engine – see below.

The same leak detected from opposite side

3. The HA3LX Evolution: Integrated Methane-Specific Detection

Building on the HZ-HA-170P's proven capabilities, our third-generation HA3LX Acoustic Camera introduces groundbreaking enhancements:

Dual-Modality Detection System

• 144-microphone array: Maintains high-resolution acoustic imaging
• Tunable Diode Laser Spectrometer (TDLAS): Quantifies methane concentrations from 5ppm*m to 50000ppm*m
• Synchronized data fusion: Overlays methane concentration clouds on acoustic leak images

Enhanced Operational Features

• Extended battery: 4+ hours continuous operation
• More Sensor: Laser rangefinder, Bluetooth
• AI-assisted diagnostics: Automatic leak classification (gas type/probability)

4. Maritime Professional Endorsements-HERTZINNO acoustic camera 170P's 138-microphone array detected propane leaks through 50mm pipe insulation while cargo compressors ran at full load. Its directional precision eliminated guesswork in valve leak identification."

- Gas Engineer

"For cascade systems where Freon leaks disrupt refrigeration efficiency, this instrument delivered unambiguous localization. The ATEX certification allowed safe deployment during gas-freeing operations."

Master's Assessment: "This technology represents a paradigm shift in gas carrier safety management. We anticipate the methane-specific capabilities of HA3LX will further enhance our bunkering and cargo transfer procedures."

3LX Redefines LNG Leak Detection

• Methane-specific quantification: Eliminates confusion between LNG components
• Simultaneous multi-leak capture: Identifies up to 16 leaks in a single scan
• Automated reporting: Generates IMO-compliant digital records with GPS/UTC stamps
• Future-ready architecture: Over-the-air updates for new gas libraries
