International Energy Efficiency (IEE) Certificate

The International Energy Efficiency (IEE) Certificate is a document that certifies a ship’s compliance with energy efficiency regulations under MARPOL Annex VI. Key features include:

1. Ship’s particulars (name, IMO number, port of registry, gross tonnage)

2. Ship type and deadweight

3. Attained Energy Efficiency Design Index (EEDI) value

4. Required EEDI value

5. Validity period and endorsements

This certificate is used to demonstrate that a ship has been surveyed and found to comply with the requirements for energy efficiency as set out in MARPOL Annex VI, Chapter 4. It is issued by the flag state or a recognized organization acting on its behalf. The IEE Certificate is crucial for international maritime operations, as it provides evidence of a ship’s energy efficiency performance. It includes the ship’s Attained EEDI, which is a measure of the ship’s CO2 emissions per capacity mile, and compares it to the Required EEDI for that ship type and size. The certificate is typically issued once for each ship and remains valid throughout its lifetime, unless a major conversion of the ship occurs or it is withdrawn, suspended, or cancelled. Port state control officers may inspect the IEE Certificate during port calls to verify compliance. Overall, the IEE Certificate plays a significant role in the global effort to reduce greenhouse gas emissions from shipping and improve the energy efficiency of the maritime industry.
