Energy Efficiency Existing Ship Index (EEXI)
Summary
The Energy Efficiency Existing Ship Index (EEXI) is a technical efficiency requirement for applicable existing ships, distinct from annual operational CII.
Why this matters in ship finance
EEXI-related engine power limitation or technical upgrades can change feasible service speed, deployment and future earnings.
The concept
EEXI compares an attained design-related metric with a prescribed requirement under MARPOL Annex VI. Compliance may involve technical measures such as engine or shaft power limitation, depending on vessel particulars and applicable rules.
How it is used in practice
Validate the vessel’s applicable EEXI technical file, restrictions and verified compliance status. Feed any speed-power constraints and CAPEX into voyage economics and the lender’s downside case.
Practical issues
Do not assume the same requirements apply to all size classes or ship types. Check technical exemptions, certificates and actual operational effects rather than assuming an EEXI pass proves low annual emissions.
How ShipFinance.ai uses this concept
ShipFinance.ai can structure this topic around a transparent, auditable record of regulatory exposure, contract allocation and related cash-flow sensitivity. A useful decision output is a base case beside a clearly labelled alternative case, with input sources, effective dates and the assumptions responsible for any change in financing capacity.
Key takeaways
- The Energy Efficiency Existing Ship Index (EEXI) is a technical efficiency requirement for applicable existing ships, distinct from annual operational CII.
- Validate the vessel’s applicable EEXI technical file, restrictions and verified compliance status.
- Do not assume the same requirements apply to all size classes or ship types.
