IMO activities on control of GHG emissions from ships:从船舶温室气体排放控制的国际海事组织活动

* The Ship Energy Efficiency Management Plan is being developed, with invaluable input from the shipping industry, as a practical tool to increase the energy efficiency of ships in operation. The Plan’s purpose is to encourage the ship operator to apply the many fuel-saving practices currently available, often referred to as “low hanging fruit”, ready for picking. The most obvious include: - Improved voyage planning (Weather routeing/Just in time); - Speed and power optimization; - Optimized ship handling (ballast/use of rudder and autopilot); - Improved fleet management; - Improved cargo handling; and - Onboard energy management (e.g. engine heat recovery), to name but a few. * The Energy Efficiency Operational Indicator (EEOI) enables operators to measure the fuel efficiency of a ship in operation. Expressed in grams of CO2 per tonne mile, the indicator enables comparison between individual ships and thereby facilitates adoption of appropriate measures to reduce energy consumption. More importantly, the Indicator makes it possible for operators and crews to monitor the effectiveness of any new measures applied in accordance with the Ship Energy Management Plan. The Energy Efficiency Operational Indicator has been implemented on a trial basis since 2005 and the outcome and experience obtained from hundreds of trials will enable the MEPC in July to adopt a mature and robust tool to gage the operational efficiency of individual ships. * The Energy Efficiency Design Index (EEDI) provides a figure, expressed in grams of CO2 per tonne mile, that measures the attainable energy efficiency of a specific ship design. It enables the designer to optimize the various parameters at his disposal and provides an energy rating for the ship before it is built. The Index will, therefore, stimulate technical development of all the components influencing fuel efficiency. Through the application of this Index, ships in the near future will have to be designed and construct
