Applicable to new ships greater than 400 Gross Tonnes
The Marine Environmental Protection Committee (MEPC) 62nd meeting took place from July 11th to 15th at the IMO headquarters in London. The meeting largely focussed on Reduction of Greenhouse Gases (GHG) from ships which led to the adoption of “Energy Efficiency Regulations” as part of a new Chapter 4 of MARPOL Annex VI.These include Energy Efficiency Design Index (EEDI) and Ship Energy Efficiency Management Plan (SEEMP).
EEDI reflects the amount of CO2 generated per tonne-mile (cargo carrying capacity). It constitutes a uniform approach to calculation of a ship’s energy efficiency during the design and build of new ships and will be used to control CO2 levels emitted for future new ships by encouraging improvements in ship design.
SEEMP establishes a mechanism for operators to improve the energy efficiency of ships through the management of individual efficiency measures.
Application
Date of entry into force will be 1st January 2013. The SEEMP will be applicable to all ships greater than 400GT whilst the EEDI will only apply to new ships, excluding those with diesel-electric, steam turbine or hybrid propulsion systems, as follows:
- Ship for which the building contract is placed on or after 1st January 2013;
- In the absence of a building contract, the keel is either laid or which is at a similar stage of construction, on or after 1st July 2013;
- The delivery of the ship is on or after 1st July 2015.
Additionally, an Administration may choose to waive the requirement for EEDI up to 4 years after each of the above dates.The Regulation pertaining to the reduction of EEDI is currently prepared to be applicable for new ships as
given in the table below. These ships will be required to have an Attained EEDI (i.e. actual verifiable values) equal to or less than the Required EEDI values (i.e. determined using Reference Lines). The required EEDI is
drawn up based on the EEDI reference line related to ships construction as shown in the table below.
Table – Reduction rate (percent) for Required EEDI versus EEDI Reference line
The EEDI Reference Line is the average energy efficiency for different classes of vessels and this is yet to be finalised by IMO. The Regulation will only apply to other ship types and sizes when the technical methods for calculation of
EEDI that relate to them have been developed.
Calculation and verification
Each applicable new ship will be required to submit information in the form of a Technical File which contains data to support the calculation of the EEDI value. Supporting information may be required as appropriate, including model test results and machinery and equipment certificates.
The EEDI will require that verification takes place at both the design stage (pre-verification) and during ship construction and sea trials (final verification) by an authorised Recognised Organisation (RO). Following
verification, an International Energy Efficiency Certificate (IEEC) covering both EEDI and SEEMP will be issued by the RO on behalf of the Flag State and will be required to be maintained onboard the ship throughout its
life. The certificate is valid for the life of the ship unless the ship undergoes major conversion.
EEDI development work
In the interim period prior to entry into force there will be continued work by the relevant working groups to finalise the technical aspects of the EEDI in time for MEPC 63.
