2 Content Why LNG as ship fuel? Regulatory development Overview on activities and technologies LNG supply chain and bunkering Outlook for LNG as ship fuel LNG as alternative fuel status and outlook No. 2

3 Drivers for using LNG as ship fuel 1. 90%-95% reduction of Sulphur-oxide emissions i required within Emission Control Areas (ECAs) by 2015 required globally by 2020, pending a 5% review at IMO by % 2. reduction of Nitrogen-oxide emissions 3% to IMO Tier III levels 2% only for pure gas engines and dual-fuel 1% four stroke engines 0% required within Emission Control Areas by % to 25% reduction of Carbon-dioxide emissions Methane slip needs to be avoided during bunkering and operation Sulphur content limits in bunker fuels Global Local 2020 LNG as alternative fuel status and outlook No. 3

6 Regulatory development IMO issued interim guidelines in These are not mandatory for flag states. GL (and also other class societies) have issued their own guidelines. GL guidelines offer additional interpretations. IMO subcommittee BLG currently works on the IGF-code. The new target completion date for the IGF Code was set to LNG Bunkering is currently addressed ISO TC 67 (ongoing) BMVBS study (completed) EMSA study (completed, not public yet) GL guidelines (VI-3-1) LNG as alternative fuel status and outlook No. 6

12 Projects exploring LNG as ship fuel for container vessels GL 1200 TEU feeder (2009) IPP 4200 TEU (2011), AiP* by GL DSME TEU (2011), AiP* by GL IHIMU TEU (2012), AiP* by GL LNG as alternative fuel status and outlook No. 12 *) Approval in Principle

13 LNG tank systems Independent tanks are required, designed in accordance with GL rules for liquefied gas carriers Type A, B or C Membrane tanks Mobile - Tanks Type C-Tank LNG as alternative fuel status and outlook No. 13 Membrane-Tank

14 Approval in principle for LNG tank container system on IPP STREAM with 4200 TEU In 2011, GL approved in principle the LNG supply system for the IPP CV STREAM with a fixed LNG tank with 1000 m 3. Additional approval in principle has now been performed for a LNG tank volume extension based on mobile tank containers delivering 1200 m 3. Mobile LNG tank containers are seen as technology suitable for short sea shipping and as range extender. LNG as alternative fuel status and outlook No. 14

16 Supply chain options for LNG as ship fuel local LNG production plant small LNG tanker local LNG storage LNG import & export terminal LNG end user LNG as alternative fuel status and outlook No. 16 LNG bunker vessel

17 Technical requirements for LNG bunkering LNG as alternative fuel status and outlook No. 17 GL performed safety assessment of LNG bunker operations to develop technical requirements within German funded R&D project BunGas. Focus on bunker vessel, safe LNG transfer, bunker station and compatibility of involved systems.

18 LNG supply and bunkering GL and Hamburg Port Authority studied LNG bunkering in the port of Hamburg within the CNSS project. A hazard identification showed that a large LNG spill due to a collision is the most critical case. The navigational safety study showed that the largest probability of a LNG bunker vessel is due to a collision when it is in transit. LNG bunker supply in north European ports will be made available with bunker vessels / barges. Sources for small cargoes of LNG are Rotterdam, Zeebrugge and Norway. Intermediate terminals are operating / planned in several ports and bunker vessels will distribute small LNG quantities in port. spe ec cost (USD/mmBTU U) Costs for LNG delivery by bunker supply vessel 5,0 4, cbm BSV in port 1000 cbm BSV from Zeebrugge 4, cbm BSV from Zeebrugge 3,5 3,0 2,5 2,0 1,5 10 1,0 0,5 0, delivered net volume per year Source: GL estimates LNG as alternative fuel status and outlook No. 18

19 Cost and benefits of LNG as ship fuel for container vessels GL and MAN performed the joint study with focus on container vessels ranging from 2500 TEU to TEU. An extension is available for container feeder vessels (900 TEU to 2500 TEU). The study shows that operating share inside ECA, LNG-HFO price difference and LNG tank costs are the dominant parameters to be considered for future LNG-fuelled propulsion solutions. Similar conclusions are valid for other ship types. LNG as alternative fuel status and outlook No. 19

20 Outlook for LNG as ship fuel Technologies concepts and systems are available Regulatory framework the new target completion date for the IGF Code was set to 2015 Bunkering today only with special permission many studies completed / ongoing local regulations expected soon Cost-benefit attractive payback py for vessels in ECAs significant environmental benefits LNG as alternative fuel status and outlook No. 20
