EEXI stands for “Energy Efficiency Design Index for existing Vessels”. It is a technical approach and sets the C02 emitted by a vessel in relation to its transport work expressed by speed and deadweight of the ship. Calculation guidelines refer to the calculation guidelines of the EEDI, with a few amendments. The EEXI applies to all vessels above 400 GT falling under Marpol Annex VI, also older vessels not falling into the scope of the EEDI.
The EEXI should not be mixed up with the CII (Carbon Intensity Indicator) within the framework of the SEEMP (Ship Energy Efficiency Management Plan). The CII is relevant for ships over 5000 GT and basically puts the CO2 emission in relation to the transported cargo and distances sailed. It is therefore an operational approach, which however will get stricter every year.
An approved EEXI technical file will be mandatory for all ships affected from January 2023. Compliance needs to be demonstrated on first annual, intermediate or renewal survey of the International Air Pollution Prevention Certificate (IAPPC), or the initial survey before ship enters into service for the international Energy Efficiency Certificate (IEEC), whichever is first on or after 1 January 2023.
A first indication you can get by using our free tool (see below). This gives you an idea if you need to improve your vessel at all or how far you are from the admissible values
We can evaluate together with you different measures how to improve your vessel by simple measures as power limiting or draught increase or other measures, which keep the performance of your vessel by reducing energy consumption or gaining energy e.g. from the wind. Please see below graphics for some ideas.
The technical EEXI file is in any case necessary and we can help you preparing it so that your vessel will be fully compliant
