Some challenges
Verification that any new technologies are commercially available and their performance is
satisfactory in the long term
Analysis of the impact of one regulation or piece of equipment on others, e.g. safety or environmental
issues
Examination of the economic impact, i.e. cost-benefit analysis
Global Logistic Chain
Loading and unloading
Transhipment
Integration
GHG emission reductions
Fuel cost savings
Million tonnes CO2 % reduction Billion US$
By 2020 180 9 - 16% 34 - 60
By 2030 390 17 - 25% 85 - 150
Estimated annual figures
IMO GHG study (2009)
Energy Efficiency Design Index
Cost: emissions of CO2
Benefit: cargo capacity & transport work
EEDI =Environmental cost
Benefit to Society
Reduction targets “X” for Bulk Carriers 20000 dwt and above1 Jan 2013 ÷31 Dec 2014: X is 01 Jan 2015 ÷31 Dec 2019: X is 101 Jan 2020 ÷31 Dec 2024: X is 20on or after 1 Jan 2025: X is 30
At the beginning of Phase 1 and at the midpoint of Phase 2, the IMO will review the status of technological developments and, if proven necessary, amend the time
periods, EEDI reference line parameters and reduction rates

LNG infrastructure
LNG or other alternative fuels that may be considered but
will not be used as an alternative to traditional marine fuels
if there is not the necessary infrastructure to support it
Role of Class and IACS
Verification of the EEDI
Minimum propulsion power
Monitoring reporting and verification
Gas-fuelled ships
Innovative energy-saving devices
Technology qualification
Structured approaches
Conclusions
Ships are the most sustainable means of transport
Challenge to apply new technologies or alternative fuels
Interfaces with other systems
Long-term performance and economic balance
Ships cannot be seen in isolation
Sustainability aspects need to be, and can be, measured
Innovation is inextricably linked to sustainability
Final consideration
The design phase for next generation of shipsthat will still be operating in 2050
will commence shortly
