7. Sustainability and Expandability
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” 8

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

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. Green Ship is a concept that evolves and changes
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
