From 2023 almost all existing ships over 400 Gross Tonnes trading internationally will be required to calculate, document and have verified their Energy Efficiency Design Index (EEXI). 


How can we help?

Morson Projects’ Marine team have developed a free-to-use tool, that is independent of any vendors, to calculate your vessel’s EEXI value and compare it to the stipulated reference value requirement. 

  1. Enter your details and that of your vessel into the EEXI Calculator.
  2. A report will be sent to your email address.
  3. Following the initial EEXI calculation, you will be given the option to purchase a Technical File which can also be produced. This can be given to your Recognised Organisation (Flag or Class) who will verify the contents and issue you with an International Energy Efficiency Certificate.
  4. If your vessel does not meet requirements, our specialist consultancy team can review your Technical File and advise on remedial action to allow your vessel to continue trading after 2023.

We are pleased to be able to offer ship owners and managers access to our in-house EEXI calculation tool with a view to helping them with their environmental obligations.

To use this tool simply follow the prompts and enter the parameters for your ship. You can also upload evidence that may later contribute to your Technical File.
