A new Chapter 4 entitled Regulations on Energy Efficiency for Ships has been added to MARPOL Annex VI which mandates:
• an Energy Efficiency Design Index (EEDI) for certain new ships;
• a Ship Energy Efficiency Management Plan (SEEMP) for certain ships; and
• a requirement for certain ships to carry an International Energy Efficiency (IEE) Certificate.
(EEDI) for new ships
EEDI is the indication of energy efficiency by co2 emission (gram)/cargo carried(ton mile)
The EEDI is a non-prescriptive, performance-based mechanism that leaves the choice of technologies to use in a specific ship design to the industry. As long as the required energy efficiency level is attained, ship designers and builders are free to use the most cost-effective solutions for the ship to comply with the regulations. The EEDI standards are being phased in from 2013 to 2025.
In general form, the EEDI formula may be expressed as:
EEDI = CO2 emission/transport work where:
• the carbon-dioxide (CO2) emission represents total CO2 emission from combustion of fuel, including propulsion and auxiliary engines and boilers, taking into account the carbon content of the fuels in question; and
• the transport work is calculated by multiplying the ship’s capacity as designed (deadweight for cargo ships and gross tonnage for passenger ships) with the ship’s design speed measured at the maximum design load condition and at 75 per cent of the rated installed shaft power.
International Energy Efficiency Certificate
All ships of 400 gross tons and above engaged in international voyages need to be issued with an International Energy Efficiency (IEE) Certificate. Owners and operators of Australian ships engaged in international trade should ensure the IEE Certificate is issued and available after the first intermediate or renewal survey, whichever is the first, on or after 1 January 2013.
