2. ENERGY EFFICIENCY ON NEW BUILDINGS WELCOMED
LOT OF POTENTIAL FROM REVIEWING BASIC ELEMENTS OF SHIP DESIGN:
Hull hydrodynamics and hull paint
Propeller design and diameter
Introduction of new and more efficient main engines
Optimised slection of auxiliary engines
Optimising cargo carrying capacity
EEDI COULD BE LOOKED AT AS A «CONCEPT» but
IT ENDED UP AS A VERY COMPLEX INDEX

3. Average improvements from the base line
Results so far promising
Tougher task for VLCCs?
Source: IMO - MEPC67/INF:4
Some challenges in design improvements
Larger propeller - cavitation, noise, stern space and aft hull hydrodynamics
Gap between MCR and NCR to allow sufficient power for severe weather
Do Mewes ducts, stator fins, propeller boss caps fins add more?

4. Historical VLCC hire and bunker costs
SEEMP is welcome
- a reflection of what ship owners already do: continuous monitoring and followed by measures for improving the operational efficiency
- a vehicle to open cooperation between ship owners and charterers for improved logistics

5. SEEMP RESULTS
Yearly improvement (index 2007) % % % %

6. SEEMP RESULTS

7. ACTUAL FUEL CONSUMPTIONS ON SISTER SHIPS
Ships can report annual aggregate fuel consumptions and aggregate values of some few other relevant transportation data
Naïve to believe it is realistic to establish fair and efficient legally-binding, fleet-wide operational efficiency standards

8. INT. SHIPPING CONTRIBUTIONS TO GLOBAL CO2
Source:
IMO 3rd GHG Study (2014)
Ships’ operations could be further improved by streamlining impractical or conflicting provisions in some regulations.
Operational efficiency could also be stimulated by simpler and more efficient port practices, control on quality of fuels provided to ships and by mandating ports and terminals to provide ships with proper services and proper assistance

SHIPPING HAS ALWAYS BEEN ENERGY EFFICIENT
SHIPS BECAME MORE EFFICIENT IN TIME
SHIPS WILL BE MORE EFFICIENT
SHIPPING WILL REMAIN THE MOST
ENERGY EFFICIENT MODE
OF TRANSPORTATION
THROUGH CONTINUOUS IMPROVEMENTS
thank you very much
