ENERGY EFFICIENCY DESIGN INDEX (EEDI) & SHIP ENERGY EFFICIENCY MANAGEMENT PLAN (SEEMP)

ENERGY EFFICIENCY DESIGN INDEX (EEDI) & SHIP ENERGY EFFICIENCY MANAGEMENT PLAN (SEEMP)

02 JULY 2012


Although EEDI was a non-mandatory instrument, IMO MEPC 62 has

made this mandatory under a new Chapter 4 of MARPOL Annex VI. This

requirement becomes mandatory on January 1, 2013 and affects both

new and existing vessels.

BACKGROUND INFORMATION

In an effort to reduce emissions of greenhouse gases (GHGs) from international shipping the first ever mandatory global greenhouse gas reduction regime for an international industry sector has been carried out by Parties to MARPOL Annex VI represented in the Marine Environment Protection Committee (MEPC) of the International
Maritime Organization (IMO). The meeting was carried out at MEPC 62 session from 11 to 15 July 2011 at IMO Headquarters in London.
The Energy Efficiency Design Index (EEDI) is applicable mainly to new ships in order to control the CO2 emissions from ships generated per tone-mile (cargo carrying capacity). The MEPC 55 on October 2009 and MEPC 59 in July 2009 agreed to a package of technical and operational measures to improve energy efficiency and reduce GHG emissions from the international shipping. Consequently, IMO has adopted the following technical and operational measures:
 Energy Efficiency Design Index (EEDI);
 Energy Efficiency Operational Index (EEOI); and
 Ship Energy Efficiency Management Plan (SEEMP).
REGULATORY FRAMEWORK & APPLICABILITY
The EEDI and SEEMP will both enter into force on January 1, 2013 within the new MARPOL Annex VI, Chapter 4 as
adopted by MEPC.203(62) on July 15, 2011.
At MEPC 63 in March 2, 2012 the IMO has adopted the following Resolutions:
 Resolutions MEPC.212(63) – 2012 Guidelines on the Method of Calculation of the Attained Energy Efficiency
Design Index (EEDI) for New Ships;
 Resolutions MEPC.213(63) – 2012 Guidelines for the Development of a Ship Energy Efficiency Management
Plan (SEEMP);
 Resolutions MEPC.214(63) – 2012 Guidelines on Survey and Certification of the Energy Efficiency Design
Index (EEDI); and
 Resolution MEPC.215(63) – Guidelines for Calculation of Reference Lines for use with the Energy Efficiency
Design Index (EEDI).

As stated above this regulation is applicable to new ships of 400 gross tonnage and above, except for ships with
diesel-electric, steam turbine or hybrid propulsions system, as follow:
 Bulk carriers
 Gas carriers
 Tankers
 Container ships
 General cargo ships
 Refrigerated cargo ships
 Combination carriers
 Passenger ships
 Ro-ro cargo ships (including vehicle carriers)
 Ro-ro passenger ships

THE CERTIFICATION PROCESS

Each ship will require its own EEDI
Following successful verification the International Energy Efficiency Certificate (IEEC) will be issued on behalf of
the flag Administration that the ship is flying. The Certificate will cover both EEDI and SEEMP and has not expiry
date unless one of the following scenarios is applicable:
 the ship undergoes major conversion; or
 the ship is withdrawn from service; or
 the ship is changing the flag Administration.
According to IMO resolution MEPC.214(63) the verification of the EEDI will be carried out in two stages as shown
below:
 Pre-verification: carried out at the design stage; and
 Final verification: carried out upon completion of the sea trials and commissioning.
The figure below shows the basic flow of survey and certification process as adopted through above mentioned Resolution.

THE EEDI
Through MEPC.212(63) the attained new ship Energy Efficiency Design Index (EEDI) is a measure of ships energy
efficiency (g/t*nm) and calculated by the following formula:
