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
