EEXI CALCULATIONS

    Energy Efficiency Existing Ship Index (EEXI)

    The Energy Efficiency Existing Ships Index (EEXI) is the IMO’s agreed method of measuring and benchmarking a vessel’s designed energy efficiency. By assessing a vessel’s output of Carbon per ton-mile of cargo carried and implementing requirements on this performance indicator, the IMO hopes to move closer to its intended target of a total carbon reduction in the shipping industry of 40% by 2030, and 50% by 2050.

    Given the potential costs to owners and operators, as well as the likely surge in demand for the installation of energy efficiency technologies, calculating the EXXI for each vessel is advisable as soon as possible to allow for planning and budgeting.

    FAQ'S

    WHEN DOES IT COME INTO FORCE?

    From January the 1st 2023, all vessels larger than 400GT to which MARPOL Annex VI applies, will be required to calculate their EEXI (Known as the “Attained EEXI”), and ensure it is below the “Required EEXI” based on the vessel type and size. This will be required by the vessel’s first annual, intermediate or renewal date of the Air Pollution Prevention Certificate, after the 1st of January 2023.

    WHAT ARE THE PRACTICAL CONSIDERATIONS?

    In practice, a vessel will be required to calculate its current EEXI, according to the calculation guidelines provided by the IMO, and ensure this is below the Required EEXI for the vessel type and size. 

    WHAT IF THE ATTAINED EEXI IS BELOW IS THE REQUIRED EEXI?

    If the attained EEXI is below the Required EEXI, then the vessel will be required to submit an EEXI technical file to an approved verification body, in order to have the International Energy Efficiency Certificate (IEEC) re-issued for compliance. 

    WHAT IF THE ATTAINED EEXI IS ABOVE IS THE REQUIRED EEXI?

    If the Attained EEXI as calculated is above the Required EEXI, the vessel will be required to adopt additional technologies to reduce the Attained EEXI; Examples of such technologies are: Engine Power Limiters, Hull Air Lubrication or Fuel Improvement Devices. After the installation and testing of the equipment, the Attained EEXI will be re-calculated (now below the Required EEXI) and the technical file submitted for verification.

    Do you need to be EEXI Compliant?

    Non-Compliant vessels are likely to be subject to detentions and increased scrutiny by port state authorities which may have an impact on their ability to trade, after 2023. It is also likely that other stakeholders such as banks, financial institutions, charterers and insurers will be unable to continue to support non-compliant ships which may lead to difficulties in obtaining financing, insurance cover and employment.
