FUEL IS EMPLOYED FOR ELECTRIC POWER AND STEAM
GENERATION

• Electric power
• Propulsion
• Engine room services
• Lighting
• Air conditioning
• Galley
• Hotel and entertainment

• Steam
• Engine room services
• A/C preheaters and reheaters
• Sanitary water heating
• Laundry
• Galley
• Evaporators

6
ENERGY GENERATION
can be optimised for improved efficiency

• Electric power generation
• Steam generation

7
Energy utilisation balance will drive fuel saving
intervention to areas with greater improvement
margin
8
Main steam users

• Sea water evaporators
• Potable water heaters
• Air conditioning preheaters and reheaters
• Tanks heating

9
Electric users PROPULSION

• Desing issues
• Itinerary planning
• Voyage planning
• Optimum ship draft and trim
• Hull cleanness and propeller efficiency, use of
  stabilisers

10
Electric users AIR CONDITIONING

• System design
• Optimum system parameter settings
• Season-dependent parameters
• System maintenance

11
Electric users LIGHTING and GALLEY

• Use of low consumption bulbs
• Automatic switch off systems
• Lighting daily management in ship areas

12
An energy saving index will measure the ships
perfomance

• Compare performance of different ships
• Compare performance of different crews
• Fix a performance indicator to monitor and
  incentive crews

CONCLUSIONS

• Focus on
• Electric power station
• Propulsion
• Air-conditioning
• Lighting
• Steam main users
• Awareness and motivation
• Energy consumption report
• Energy saving index
• Design issues

THE FUTURE

• Application to the whole Costa fleet
• Evolution of the approach - further
  investigations and tools
• Automation, measurement tools and data collection
• Design issues, joint projects with shipyards and
  research studies
• Fuel quality vs price
