GL issues the first EEDI certificate

Industry Database

The first-ever Energy Efficiency Design Index (EEDI) certification for a large container vessel owned and operated by Hapag-Lloyd has been conducted by Germanischer Lloyd (GL).

The EEDI certificate was issued in accordance with the voluntary EEDI guidelines, MEPC.1/Circ.681 and 682 of the IMO.

Hapag-Lloyd says that the certification emphasises its leadership in sustainable container shipping. The attained EEDI value of the Hapag-Lloyd vessel was found to be significantly better than the present average for vessels of this size (based on Lloyds database), underlining the high energy efficiency of the vessel’s design. The company goes on to say that this privdes proof of leading members of the maritime industry pro-actively pursuing measures to improve the energy efficiency of merchant vessels, thus reducing CO2 emissions considerably.

In 2003, IMO initiated developments to reduce greenhouse gases from ships. The recent focus has been on the EEDI which is conceived as a future mandatory newbuilding standard. The EEDI compares theoretical CO2 emissions and transport work of a vessel (gCO2/(tnm)) and will eventually be benchmarked against an IMO-set requirement.

As the individually attained EEDI for a ship represents the basic energy efficiency of a design, it can be used as a benchmark within an operator's fleet as well as for a comparison against a competitor’s fleet. Benchmarking against the ship’s operations is possible too. This means that the determination of the EEDI makes sense for ships already in service, provided all data for a complete EEDI technical file are available.

For the verification of the EEDI, a technical file is established, which summarises all relevant technical data, and documents the calculation procedure towards the final EEDI value. GL believes that some issues in this context require more attention from IMO and, therefore, these items have been forwarded to the German flag state administration for possible consideration at future IMO meetings.

GL has worked on research and contributed to the IMO’s EEDI development programme on behalf of the German Ministry of Transport, Building and Urban Development, particularly in interpretation and verification of the EEDI. With the introduction of the EEDI certificate, GL says that it has extended its portfolio of services on energy efficiency of ships, ranging from certificates to consultancy, which is provided by GL’s FutureShip subsidiary.
