  1. _LNGready • Neptun Ship Design LNG READY

  2. _LNG Experiences 2009 – Design offerfor a LNG-fuelled power plant – inquiredby MAN Ref. MAN 2009/10 – Investigation toconvert a conventional Ship Design to a gas fuelledone. Partners: MAN/GL 2012 – R&D Project – Power Generation Conceptfor a LNG-Storage andProduction Offshore Platform Ref. Siemens 2011/13 – Design for a Gas Fuelled Feeder Container Vessel. Approval in Principleby DNV Partner: Hansa Shipping Today  All newdesignswith different levelsofpre-outfittingfor LNG

  3. _LNG cleanest option to fulfil MARPOL Annex VI Ref. www.dieselnet.com

  4. _LNG cloud or another Loop in Ship Design Rules North America IGF code TIER III ECA MSC.285(86) Class MARPOL North Sea Baltic Sea TIER II LNG 4stroke Boil off 2 stroke Cylindrical Low Pressure Prismatic High Pressure Gas tank Gas prepare Main Engine Vacuum Gas System Blow off Gas modeoptimized Liquid fuelassecondorasback-up Safety Gas transfer 2nd barrier Inertizing Burstingdiscs Aftertreatment Bunkering SCR EGR

  5. _LNG how to start? Main Design Criteria Best Transport Efficiency (TE) for Intended Service FGC TE = ____________ TEUhomx nm Service – Transportation Task defined by Owners according real needs

  6. _Decision for Main Engine Otto cycle againstDiesel cycle Low pressure <10 bar High pressure up to 300 bar 4 stroke and 2 stroke 2 stroke Pilot/ Liquid fuel 1% 3-5% Amount of liquid fuel constant Amount of liquid fuel increase with lower loads Operating at all loads in gas mode At 15-20% load switch to 100% liquid fuel Maximum output Optimized for gas operation Diesel engine operating on liquid fuel and gas Operating with liquid fuel is less efficient, just back-up only Lower maximum output Same maximum output like conven- tionalone Aftertreatment Tier III in gas mode Tier III in gas mode by EGR Tier III in liquid fuel mode by SCR Tier III in liquid fuel mode by EGR No aftertreatment in gas mode Aftertreatmentin all modes Methanslip 2-4% of SFOC 0.1% of SFOC Gas quality Min. MethanNumber of 80, No limits for methan number which is near half of global supply

  7. _Decision for Main Engine There still remainsthequestionforthedecisionmaker: Trust, Experiences, Better Marketing, Needs, Advantages?

  8. _LNG Tank Arrangement LNG storagetanks

  9. _LNG Tank Arrangement Target Risk Facts Substitute of liquid fuelbunkerwithoutanylosses Loss ofspace, dead-weight, stability 3.5-fold spacerequirementagainst liquid fuelfor C-Tanks and 2.5 for B-Tanks Challenge ofCompromise

  10. _LNG Tank Arrangement proposals • Advantage: • Nolossofcargospace • Fitsforlaterinstallation • Disadvantage: • Weightdistributionaft • High COG

  11. _LNG Tank Arrangement proposals • Advantage: • Nolossofcargospace • Lower COG thanproposalbefore • Disadvantage: • Partiallysuitableforlaterinstallation

  12. _LNG Tank Arrangement proposals • Advantage: • Best regarding COG andweightdistribution • Nearestto Engine room • Disadvantage: • Loss ofcargospace • Nolaterinstallation

  13. _Development project for Hansa Shipping LNG READY

  14. _Basic Design Requirements Owners Requirements: technical specification, description of the vessel operational profile Class Requirements: construction rules LR, DNV, GL, BV … Statutory Rule Requirements: IMO, SOLAS, MARPOL to consider: emission control areas heat recovery systems EEDI - index ballast water treatment Economic Requirements: minimized service cost fuel oil efficiency minimized construction cost (Light ship weight), effective design process Loops of Ship Design Process
