Green Ship Concept
•
Sustainability and Expandability
- based on stakeholders’ chain of responsibility
•
Rule Minimum + Something
- ambitiousness and being ahead of legislations
Tripartite Meeting 2010, Tokyo
7
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”

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
