Explore the critical process of liquefied gas measurement on ocean-going vessels transporting LNG (liquefied natural gas), LPG (liquefied petroleum gas), and other hazardous chemicals. This episode dives into how accurate custody transfer measurements are performed on massive ships carrying billions worth of cargo, ensuring trade accuracy, safety compliance, and environmental monitoring.

Learn how modern marine measurement technology like radar level gauges, platinum resistance thermometers, and onboard gas chromatographs deliver precision in challenging conditions — including the extreme cold of LNG at -162°C. We explain why factors such as tank level gauging, temperature stratification, vapor pressure, and gas composition analysis are vital for correct cargo quantity accounting and methane emissions reporting.

Key insights include the role of ship’s master responsibilities, the importance of rigorous instrument calibration and verification, and how international industry standards ensure measurement uncertainty is kept below ±0.25%. Discover how this complex engineering underpins billions in global energy trade, supports safe maritime operations, and advances environmental compliance in the shipping industry.
