IMO Symposium on a Sustainable Maritime
Transportation System
London, 26 September 2013
Energy Efficiency and Implementation of
New Technologies in the Context of
Sustainable Shipping
Roberto Cazzulo
Chairman of the IACS Council and of RINA Services S.p.A.
Summary
Role of new technology and innovation
Air emissions
Energy efficiency
Safety
Safety
Society
Economy
Environment
Sustainability
Ships are part of an integrated logistics and transport chain and therefore
need an effective and efficient supporting infrastructure
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

Energy Efficiency Design Index
Environmental cost
EEDI =
Benefit to Society
Cost: emissions of CO2
Benefit: cargo capacity & transport work
Reduction targets “X” for
Bulk Carriers 20000 dwt and above
1 Jan 2013 ÷31 Dec 2014:
X is 0
1 Jan 2015 ÷31 Dec 2019:
X is 10
1 Jan 2020 ÷31 Dec 2024:
X is 20
on 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 ships
that will still be operating in 2050
will commence shortly
