Liquefied Natural Gas (LNG) is gaining popularity as a more environmentally friendly fuel alternative for ships as it emits less carbon dioxide than coal or oil. As per January 2023, there are more than 350 LNG- fueled vessels in operation and more than 500 on order. In mid-2022, an Indonesian state-owned enterprise announced the development of the first LNG bunkering facility in the country. The engineering design of the facility will certainly include a measurement system for the LNG to be transferred to customers’ ships or vessels. To date, tank gauging has been the only measurement system for LNG transactions in Indonesia’s LNG Terminals both in Kalimantan and in Papua. The tanks used for measurement are the buyer’s ship cargo tanks that must undergo certification by Direktorat Metrologi before LNG loading can commence. For bunkering needs, the LNG flow meter may be the more feasible option as the method for measurement considering there will be more vessels that come and go to refuel at the bunkering facilities. To certify each vessel before bunkering would not be the most efficient way for measurement. It is common practice for LNG flow meter to be used as back up measurement in LNG transactions. Ultrasonic Flowmeter and Coriolis Meter are two types of flow meters used for LNG measurement. The use of a flow meter equipped with a flow computer with the right design can make liquid measurements and calculations more accurate than static measurements. This paper will mainly discussed the concept of new metering application using perspective approach and considering the risk of legal compliance, onward.
