  1. The Green Ferry:Low Emissions, Low Wake & Operational Efficiency Matt Mullett Chief Executive Officer ALL AMERICAN MARINE

  2. Low Emissions • The “Right” thing to do

  3. Low Emissions • The “Right” thing to do

  4. Low Emissions Legislative mandates EPA Tier III – Marine Engines 2013-14 EPA Tier IV – Marine Engines 2017 Challenge Available technology Economic viability

  5. Low Emissions • Biodiesel • Pros • More Biodegradable • Less toxic • Renewable Resource • Cons • Availability and Cost • Engine OEM’s reluctant to accept blends greater than B20 or B30 • Meet ASTM Manufacturing Specifications • Cleans out the system, clogs filters • Overall Impact from Corn to Combustion = more emissions

  6. Low Emissions • Selective Catalytic Reduction (SCR)

  7. Low Emissions • SCR Systems • Pros • Removing harmful emissions: NOx & SOx • By-products – water and ammonia • Cons • Marinization of industrial and highway technology • Build boat around system • Weight • Burn more fuel • Better off building lighter, smaller engines, burning less fuel emitting fewer emissions

  8. Low Emissions • After-Treatment Filters Catalyzed Particulate Filter for Diesel Engines • Pros • 99% of Carbon monoxide • 99% of Hydrocarbons • 85% Particulate Material • Provides additional sound attenuation • Cons • No provisions for NOx and SOx treatment • Back pressure

  9. Low Wake • Vessel wake – An issue here to stay

  10. Low Wake Rich Passage Wake Wash Study

  11. CFD Modeling & Testing VIRTUAL TANK TEST • Teknicraft Design, Ltd. • University of Iowa’s IIHR-Hydroscience & Engineering Research Center • Iowa’s Institute of Hydraulic Research (IIHR) • CFDSHIP-IOWA • INSEAN Naval Architects (Rome, Italy) • Potential Flow Code • Refine design features for low wash and energy

  12. Virtual Test Tank • Wake Wash Elevations

  13. Reliability of the Model

  14. Refining the Revision

  15. Vessel Optimization Study • 3 Different hull shapes • 3 Different hydrofoil profiles • 9 New vessels

  16. Vessel Optimization Study - 83’ LOA - Quad Jet Boat - 118 passengers - 37 knot cruise speed

  17. Operational Efficiencies • Economic necessity • Minimize hull resistance • Maximize fuel efficiency • Evaluate propulsion systems

  18. Weight Watchers • Put your boat on a diet • Weight Inventory • Weigh on & off • Check for Fouling

  19. Operational Efficiencies • Bottom Paint • Intersleek 900 • Up to 9% fuel and emissions savings compared to biocide antifoulant coatings with self polishing copolymers • Necessary Expense

  20. Consumption Comparison • 80’ Monohull (150 pax) • 450 gallons/day • 72’ Catamaran (150 pax) • 400 gallons/day • 83’ Teknicraft (150 pax) • 330 gallons/day • same engine model

  21. Displaces 1/3rd of the vessel’s weight • Uses 1/3rd less horsepower • Burns 1/3rd less fuel Effective at 17 knots

  22. SYMMETRICALBOW WAVE PIERCER

  23. ASSYMETRICAL TUNNEL

  24. HYDROFOIL SYSTEM

  25. Cheaper

  26. Flat Fuel Consumption

  27. Design Characteristics • Lightweight aluminum construction • 5383 Marine Grade Alloy

  28. Operational Efficiencies • Fuel Management Systems • Fuel Flow Meters • Most efficient operating rpm levels

  29. Operational Efficiencies • Fuel Treatment Systems • Enhance Combustion • Economize fuel potential

  30. Operational Efficiencies • Diesel Electric

  31. Operational Efficiencies • Diesel Electric • Pros • Consistent Load, predictable fuel consumption • Cons • Size and Weight • Availability of Motors • Speed • Loss of efficiency during power conversion

  32. Operational Efficiencies • Hybrid Transmissions • Gear box with an electric motor input • Eliminate the propulsion prime mover • Issues • Suitable electric motors • Power generation for motors • Genset • Batteries

  33. Operational Efficiencies • Solar • Expensive • Real Estate • Weight • Speed: 7 knots

  34. Operational Efficiencies • Wind • Not suitable for most ferry applications • Efficiency

  35. The Green Ferry:Low Emissions, Low Wake & Operational Efficiency Existing & emerging technologies Beware of “Smoke & mirrors” Economic realities Do your homework

  36. Thank You
