Developments in Green Ships Design/Technologies

1. Developments in Green Ships　Design/Technologies By Dave Iwamoto 15 October 2010

2. Restriction of Emission from Ships Ship recycle (not in force) NOx and SOx restricted Halon & CFC prohibited VOC prohibited in special port Incinerator Noise restricted (in study) Oil discharge monitoring Sewage treatment Garbage disposal Ballast water management (not in force) TBT prohibited Bilge discharge

3. Green Ship Design Low GHG exhaust Ship operation Less fuel oil consumption at sea Device for less energy Diesel engine exhaust Low Nox and SOx Inventory Less hazardous materials Vapor emission control system for tanker Incinerator Noise Reduction Oil discharge monitoring for tanker Sewage treatment Garbage disposal Gray-water treatment TBT-free painting Ballast water treatment Bilge-oil discharge control Best hull form & propulsion Less fuel oil consumption at sea Less ballast ship

4. Green Ship Design Low GHG exhaust Ship operation Less fuel oil consumption at sea Device for less energy Diesel engine exhaust Low Nox and SOx • Propulsion Plant • High efficient engine • Hybrid diesel engine Inventory Less hazardous materials Vapor emission control system for tanker Incinerator • Development in alternative engine • Electric motor driven (Fuel cells, electric batteries) • Dual fuel diesel engine • Bio fuel diesel engine • GTL, DME engine Noise Reduction Oil discharge monitoring for tanker Sewage treatment Garbage disposal Gray-water treatment TBT-free painting Ballast water treatment Bilge-oil discharge control Best hull form & propulsion Less fuel oil consumption at sea Less ballast ship

5. Green Ship Design Low GHG exhaust Ship operation Less fuel oil consumption at sea Device for less energy Diesel engine exhaust Low Nox and SOx Inventory Less hazardous materials • Operation • Optimized transport chain • Route optimization (Weather routing) • Optimized driving • Trim /ballast water optimization Vapor emission control system for tanker Incinerator Noise Reduction Oil discharge monitoring for tanker Sewage treatment Garbage disposal • Device for Less energy • Cold ironing • Wind & solar energy • Additional thrust (Kites) Gray-water treatment TBT-free painting Ballast water treatment Bilge-oil discharge control Best hull form & propulsion Less fuel oil consumption at sea Less ballast ship

6. Green Ship Design Low GHG exhaust Ship operation Less fuel oil consumption at sea Device for less energy • Hull form & propulsion • Less resistance (Wave, Viscous, Wind) • High efficient propulsion, CRP Diesel engine exhaust Low Nox and SOx Inventory Less hazardous materials Vapor emission control system for tanker Incinerator • Less energy • Less ballast ship, Weight saving of L/W • Optimized systems (Auxiliary machinery, Waste heat recovery, Air-conditioning system, Electric motor driven deck machinery, etc.) • Less electric demand (LED illumination) • Micro bubble or air lubrication Noise Reduction Oil discharge monitoring for tanker Sewage treatment Garbage disposal Gray-water treatment TBT-free painting Ballast water treatment Bilge-oil discharge control Best hull form & propulsion Less fuel oil consumption at sea Less ballast ship

7. Green Ship Concept • Sustainability and Expandability - based on stakeholders’ chain of responsibility • Rule Minimum + Something - ambitiousness and being ahead of legislations

8. Shipowners Challenge for Eco-friendliness Recently in Focus: • Optimized hull and propulsion • Optimized machinery efficiency - waste heat - domestic waste etc. • Waste minimization spirit reflected in operation manuals • Renewable energy • Drag during operation e.g.; NYK’s “NYK SUPER ECO SHIP 2030” MOL’s “ISHIN”

9. Schematic Outline of Promotion Proposal On Green Innovation KEIDANREN Japan, March 2010 (part of “Japan as Creating Country” Initiative) 1. Basic Vision • Use of technology …… 2. Policy on Latest Technology Pursuit • Stimulating demand • Education • Regulatory framework towards model project • International activities (GHG reduction included) 3. Green Innovation • Creating seeds (fund supporting element) • Development (green technology platform) • Actual use (support measures element)

10. Technical Challenges to Reduce Environmental Burden In Japanese Shipbuilding Industry • Main engine and auxiliaries • Combustion efficiency • Waste heat recovery • Dual fuel main engine • Alternative fuel / Fuel cell / Batteries • Hull and hull form • Larger hull body, lighter construction • Improved hull form • Reduced drag (resistance) continued....

11. Technical Challenges to Reduce Environmental Burden In Japanese Shipbuilding Industry (cont.) • Propulsion • Improved propeller system • Energy saving appendages • Operation and maintenance • Sophistication (e.g. Weather routing) • Support tools (e.g. Performance monitoring) • Change of mode (e.g. Slow steaming) • Green Ship • Emission quality • Pollution prevention • Noise reduction

12. Summary • Green Ship is a concept that evolves and changes • Technology is the key element - careful follow-up is required • Stakeholders need to understand the chain responsibility • Narrow minded concentration of own interest is discouraged • Close coordination and cooperation needed among stakeholders lead by private sector • Regulation will follow but what can we seek beyond? • There are useful individually developed practices • Ambitious mind setting to go beyond rule requirements
