Summary
1.Do we need dedicated regulations for LNG-fuelled ships?
2.Current regulations in force(IMO)
3.New developments
4.Future regulations - prospects

Reasons for dedicated regulations
(safe and environmentally-friendly design,
construction and operation of ships)
•Fuel flashpoint limit ≥ 60ºC/43ºC
[SOLAS II-2/R.4]
•LNG(low-flashpoint fuels) properties/associated risks

Current regulations in force
1.IMO regulations
2.Class regulations
3.ISO standards
4.EU/National regulations
5.Industry standards
6.Local/regional regulations (ports)

IMO regulations in force
• Res. MSC.285(86) [year 2009] Interim guidelines on safety for natural gas-fuelled engine installations in ships.
• IGC Code (Chapter 16:use of cargo as fuel)
• SOLAS Convention

New development
CODE OF SAFETY FOR SHIPS USING GASES OR OTHER LOW-FLASHPOINT FUELS
IGF Code
![Page 7: LNG fuelled ships - regulations - GoLNG | Main page fuelled ships... · 2014-10-24 · LNG fuel quality - specification Typical LNG gas composition in volume(Res.MSC.285(86)) •Methane](https://reader033.fdocuments.us/reader033/viewer/2022042911/5f441c2e02f52848fc5cdc9e/html5/thumbnails/7.jpg)
IGF CODE –entry into force
CCC 1(Sep 2014) -> MSC 94(Nov 2014) -> MSC 95(June 2015)
Entry into force
01.01.2017 ?

IGF Code - application
• Passenger ships
• Cargo ships ≥ 500 GT
• Ships converted to use low-flashpoint fuels
• Recommended for cargo ships ≤ 500 GT
(up to Administrations)
• Not applicable to ships covered by IGC Code /Ch.16

IGF Code
•Holistic approach
•Goal based approach
•Mandatory criteria
•Vast applicability
IGF Code regulates arrangement, installation and operation of machinery, equipment and systems for vessels to minimize the risk to the ship, its crew and the environment.

LNG fuel quality - specification Typical LNG gas composition in volume(Res.MSC.285(86))
• Methane (C1) 94.0%
• Ethane (C2) 4.7%
• Propane (C3) 0.8%
• Butane (C4+) 0.2%
• Nitrogen 0.3%
