Standards Development

Scope

•This standardization proposal adds a Coriolis Mass Flowmeter and GC (Gas Chromatography) to an existing system and made by the portable package to create a system to measure the exact supply of the feed gas fuel and to utilize LNG bunkering. This is used to measure and standardize the actual LNG bunkering supply of Truck to Ship.

•Portable packaging of the system to measure supply flow in order to minimize facility storage space and streamline the use of development systems.

•Develop gas fuel metering systems by standardizing related technologies and measurement methods to standardize the transactions between suppliers and suppliers of gas fuels in calorie units, the costpaying unit for commercial and household supply of LNG.

•The document consists of definitions of related terms, abbreviations, general requirements, metrological requirements, system flawless requirements, requirements and test methods for the installation of a weighing system, procedures, and appendices for measurement methods.

Purpose

Package and standardize the flow system for Truck to Ship bunkering of LNG propulsion vessels using Coriolis flowmeters and Gas Chromatography to quickly calculate and store the vessel's quantity/quality, thereby reducing time lost in the ship's flight schedule. It aims to reduce stakeholder disputes caused by supply/demand quantity differences.

Is there a verified market need for the proposal?

LNG Fueled Vessel

•The establishment of international and regional Clean Zones has strengthened the regulation of the national and regional ship SOx emissions.

•Increased EPA Tier has led to tighter emission regulations.

•All ships need to reduce their emissions.

•The increasing number of LNG fueled vessels that can pursue economic and environmental simultaneously

Truck to Ship Bunkering

•One of the main advantages of TTS (truck-to-ship) bunkering is its relatively low investment cost.

•Trucks used for bunkering are useful because they can also be used for other purposes such as LNG distribution.

•TTS bunkering has the advantage that there are many LNG supply areas.

•For these reasons, TTS bunkering is the most widely used method for bunkering ports in LNG fueled ships.

What problem does this document solve?

•Mass flow measurement is important throughout the industry as it eliminates inaccuracies due to the physical properties of the fluid.

•Coriolis flowmeters can leverage the Coriolis effect to improve the measurement procedure by providing direct and accurate mass flow measurements of both liquids and gases during the bunkering process.

•Coriolis flowmeters reduce tampering and can prevent 'cappuccino's bunkers, alleviating bunker quantity disputes.

•GC (Gas Chromatography) can decompose components of complex mixtures containing hundreds of components in a single sample and have very low detection limits for certain compounds with heteroatoms such as halogens, nitrogen, phosphorus, and sulfur, accurately measure fuel components to improve bunkering efficiency.

•GC is a fully quantitative technique that can provide accurate data such as the number of peak areas for quantitative estimation.

What value will the document bring to end-users?

•We will build and evaluate a flow system for Truck to Ship bunkering of LNG fueled vessels.

•A mobile package flow measurement system will be developed.

•A manual for the LNG bunkering TTS weighing system will be developed.

•In the future, small and medium LNG ships will be used for direct transport to small and medium LNG storage stations, LNG bunker fueling stations or demand destinations. Since the sampling/gas analysis system will be expensive to build, the application of this flow system standardization technology can increase the economical / convenience.

•By using this flow system standard technology when LNG bunkering to LNG fueled ship by LNG bunker supply ship, it is possible to quickly calculate and store the quantity/quality of the ship and reduce the time loss of the ship's operation schedule. This can eliminate stakeholder disputes over quantity differences.
