  2. Who is AVL from Graz/Austria? World'slargestprivatelyowned and independentcompany for • engineeringofpowertrainsystems (combustion engines, hybrid systems, electricdrives) • softwareforengine and vehiclesimulation • instrumentation and testsystems • Involved in morethan 1,500 enginedevelopmentprojects • More than 4,000 testbedinstallationsexecuted • Founded 1948 • > 6,200 employees worldwide • 45 representations & affiliates worldwide • > 1,000 Mio. € turnover in 2012

  3. AVL covers all Engine Segments Engineering Marine Power Plants Locomotive Simulation Construction Agriculture Commercial Vehicle Testing Passenger Cars 2-Wheelers Racing WearemarryingIndustry Needs with Innovation.

  4. AVL is well-knownfor … Engineering Simulation Testing … but we are also out in the field supporting the operators!

  5. AVL Large Engine References(Examples out ofmorethan 130 Projects)

  6. SustainableShippingDrivers • Whatarethedriversfor 'SustainableShipping'? • increasedsensitivityforenvironmentprotection on political and publiclevels • upcoming international and localrequirementsforemissionreduction (e. g. IMO Tier 3, US EPA Tier 4 Marine, EU Harbour Directive, …) • currentlowlevelofcharterrates • increasedpricelevelofclassicalstandard marine fuels (HFO, MDO) • customersstrivingfor 'greenimage' NYK Wilhelmsen

  7. SustainableShippingTopics • Whatmeans 'SustainableShipping' fromtheengineperspective? • Slow steaming ??? • Engine derating ??? • This istoo simple - thetopicsare: • Improvedengineefficiency • Wasteheatrecoveryfor power generation • Clean fuels • Reducedengineemissions (internal & byexhaust aftertreatment) • Power generationsystemintegration & flexible power distribution • Conditionmonitoringforensuranceofoptimumengineoperation • Hybrid systems, sails, … (at least fornicheapplications) • See followingexamples …

  8. ExampleIMO Tier 3 Fulfilment Options • Cooler requirement • Valve train • Turbocharging • Architecture • EGR rate • Cooled / uncooled • SSTC / TSTC • ECA / Non ECA • Power Density • Part loadoperation • Transient operation • Multiple injection • HFO capability • Injectionpressure IMO 3 • Cylinder head modification • Type of EAS • Injection potential • HFO capability • Sulphur Content • Gas pressure • Packaging • Valve dimension • Transient operation • ECA / NonECA & DF • Part loadoperation • Packaging • Conversion rate • ECA / Non ECA • Valves • Diesel / Gas • Combustion layout • Exhaust temp. • SSTC / TSTC • Urea Dosing

  9. ExampleIMO Tier 3 Fulfilment – EGR Variants

  10. ExampleDual-Fuel Engine Usage • AlreadyExisting: • LNG Carriers • OSVs • Cruise Ferry • Product Tanker • Ordered: • Container Vessels • Cruise Liners • Expected Future: • River Boats and Coasters • Auxiliary Engines on large Cargo Vessels • Main Propulsion Engines on large Cargo Vessels www.marinelog.com Ship & Offshore www.ship-technology.com Ship & Offshore Germanischer Lloyd / Wärtsilä

  11. ExampleDual-Fuel Engines – Applied Technologies Dual-Fuel Medium-Speed 4-Stroke HFO-/Gas-Operation Low-Pressure Gas Supply PremixedCombustion Dual-Fuel Slow-Speed 2-Stroke HFO-/Gas-Operation High-Pressure Gas Supply Diffusion Combustion Wärtsilä MAN Diesel & Turbo

  12. ExampleDual-Fuel Engines – R&D Activities Performed on AVL's medium-speed SCE • Achieved Performance Values: • 27 bar BMEP • 45 % effectiveefficiency • < 3 % COV-IMEP • (@ 2 g/kWh NOx) • optimumefficiencyvalues @ approx. 1 % pilotfuelamount • higherpilotfuelamountscausehigher NOxemissions • A/F-ratio  tokeep NOxstable • retardedcombustion, HC ,  

  13. ExampleCondition Monitoring (AVL EPOSTM) • Benefits: • earlydetectionofupcomingfaults and avoidanceofdamages • regularengineoperationoptimizationpossible • unplannedrepairworkscanbechangedtoplannedmaintenanceworks • experienceshowoptimization potential upto3 % efficiency ( 4 … 6 g/kWh) on usualmaintained engines, evenhigher on poormaintenedengines  respective CO2reduction potential • consequentuseofdeliveredinformationaboutenginestatusenablessavingsofupto 100.000 US-$ per year
