committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Due to numerous economic and environmental factors, the use of liquefied natural gas (LNG) as fuel
for marine applications has increased. The 0,10 % sulfur limit, in the sulfur emission controlled areas
in Europe and the US, which entered into force on 1 January 2015 has been one of the major driving
forces for using LNG as fuel for marine applications. The decision for the 0,50 % global sulfur limit from
1 January 2020 by the International Maritime Organization (IMO) might further increase the interest
in LNG. The International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code)
was a response to the need of guidance in this emerging market. Since LNG-fueled vessels are likely
to bunker LNG in different parts of the world, a common specification is needed for ship owners, ship
operators and LNG suppliers. It would help engine manufacturers and ship designers and it is beneficial
for the development of this new alternative marine fuel market.
In 2018, IMO adopted an initial strategy on reduction of greenhouse gas (GHG) emissions from ships.
The strategy includes the objective to peak GHG emissions from international shipping as soon as
possible, whilst pursuing efforts towards decarbonizing the sector as soon as possible in this century.
It also includes the objectives to reduce the CO emissions per transport work and total annual GHG
emissions from international shipping by 2050, with an interim target in 2030. Thus, LNG produced
from renewable sources as biomethane that can reduce CO emissions when used as marine fuel is also
addressed in this document.
LNG is produced in different locations in the world in liquefaction plants. Large scale production
facilities are often dedicated to specific markets such as natural gas grids and large power plants
that use their own standards. This document takes into consideration this major constraint for any
adaptation to marine applications specificities/requirements.
