Standards Development

Scope

The proposed document gives guidance for quantification of liquefied natural gas (LNG) as marine fuel on board LNG bunkering ships.

It is applicable to the measurement of LNG from any source, e.g. gas from conventional reservoirs, shale gas, coalbed methane, at the time of - Ship to Ship (STS) transfer to LNG-fuelled ships,

- Ship to Ship (STS) transfer between LNG bunkering ships, and

- transfer to or from shore tanks or other facilities, with no regard to the type of tanks.

This document is also applicable to the quantification of biomethane and synthetic methane from fossil fuels or renewable sources.

Purpose

LNG is one of the most possible alternative fuel for marine applications to reduce CO2 emission at this moment. Numbers of LNG-fuelled ships are increasing recently, and ship to ship transfer of LNG fuel has been started newly. The demand of LNG fuel will increase due to growth of the number of LNGfuelled ships in the future.

Various measurement methods to quantify LNG will be employed trade by trade which could be the cause of complications, inefficiency and dispute.

Establishment of this international standard contributes to growth of trade and reduces CO2 emission from marine sector, consequently.
