13 Regulatory framework International regulations National/regional regulations Class rules 14 Rev. 2

14 National regulations for gas fuelled ships January 2000: Car ferry Glutra delivered Political push for use of LNG in Norway Road Directorate wanted to test the use of clean LNG fuel How to approve this novel design? Draft national regulations Applied applicable parts of rules for Liquefied Gas Carriers, e.g. piping, tank certification etc. Used class notes and certification notes for gas fuelled engines 15 DNV GL September 2017

16 Development of international regulations June 2015 January 2017 NMA draft to IMO Interim Guidelines MSC.285(86) MSC95 IGF Code adopted IGF Code Enter into force The process for development of an International Code for gas fuelled ships in IMO was initiated by the Norwegian Maritime Authority (NMA) in

17 International Regulations The IGF Code entered into force 1 January 2017 Mandatory for all ships using gas and other low flashpoint fuels Detail requirements for natural gas (LNG, CNG) Other low flashpoint fuels allowed, approval based on alternative design approach 18 DNV GL September 2017

18 Development of international regulations September 2014 June 2015 January 2017 NMA draft to IMO Interim Guidelines MSC.285(86) Phase 2 development of the IGF Code initiated MSC95 IGF Code adopted IGF Code Entry into force Phase 2 development of the IGF Code continues The development of international regulations for low flashpoint fuels continues in IMO by a phase 2 development of the IGF Code. More detailed provisions for methyl/ethyl alcohol fuels and fuel cells is currently under development in IMO correspondence group reporting to IMO Subcommittee CCC. 19

19 Next step: Hydrogen as fuel 20

20 Regulatory status hydrogen as fuel The IGF Code does not provide specific design requirements for fuels other than natural gas (LNG, CNG). When e.g. hydrogen is used as fuel, the IGF Code Part A requires that an Alternative design approach is followed. 21

21 IGF-Code Part A: Functional requirements The safety, reliability and dependability of the systems shall be equivalent to that achieved with new and comparable conventional oil-fuelled main and auxiliary machinery. 17 additional functional requirements follow, which shall be fulfilled through the ship design. It is emphasized that operation procedures shall not replace safety barriers through the ship design. 22

22 IGF-Code Part A: Risk assessment: A risk assessment shall be conducted to ensure that risks arising from the alternative design are addressed. It is important to note that safety barriers that are acknowledged for natural gas, might not be accepted for use for hydrogen as fuel. Limitation of explosion consequences There are requirements to the consequences of explosions in the rooms that contain leakage points. 23
