ISO 6919

Measurement of refrigerated hydrocarbon and non-petroleum based liquefied gaseous fuels — Dynamic measurement of liquefied natural gas (LNG) as marine fuel — Truck-to-ship (TTS) bunkering

The proposed document defines procedures and requirements for transporting liquefied natural gas (LNG) from trucks to ships (TTS) using the combination of Coriolis mass flowmeter (MFM) and gas chromatograph (GC). It also gives guidance for portable packaging of the combination system in mobile form which minimizes facility storage space and streamline the use of development systems. Output from the system in calorie units is applicable to commercial transactions between suppliers and users of liquefied natural gas (LNG) as marine fuel. The proposed document consists of definitions of related terms, abbreviations, general requirements, metrological requirements, system flawless requirements, requirements and test methods, procedures, and appendices for measurement methods.
