EEXI – Regulatory and Compliance

In 2020 IMO introduced the Energy Efficiency Existing Ship Index (EEXI) which is a technical framework concerning all existing ships above 400 GT. All ships must develop an approved energy efficiency improvement and decarbonization plan based on the requirements for each type of vessel. EEXI is a technical or ‘design’ efficiency index that requires a vessel to achieve a required level of technical efficiency (required EEXI) under specified reference conditions. Compliance is determined by the vessel’s design and arrangements. This means an attained EEXI can only be changed through alterations to the vessel’s design or machinery and NOT day-to-day operational activities such as speed reduction or reduced cargo.

We can support you in developing a Feasibility Study. The result is an indication and is based on the Guidelines that are still under development. The outcome will provide you with a preliminary calculation and advice. We can however also offer further assistance with the final Techical File and submitting it to class or the regulatory body at a later stage.

The Feasibility Study includes:

• Calculation of the attained EEXI of a given ship, based on the Draft Guidelines
• Comparing the result with the Required EEXI
• Estimation of the required EPL (Engine Power Limitation) to meet the Required EEXI (since it is the most effective, cheapest, and least invasive way to improve EEXI)
• We can issue a Preliminary Technical File taking into account the EPL.

If the EPL is not enough to meet the Required EEXI, we can further discuss alternative options like EET to improve the EEXI for non-compliant vessels
