The Energy Efficiency eXisting ship Index (EEXI) is a measure which was introduced by the IMO to reduce the greenhouse gas emissions of ships. The EEXI is a measure related to the technical design of a ship. In case no changes to the energy efficiency are applied, ships have to attain EEXI approval only once in a lifetime.

2023年1月1日 · New statutory requirements entered into force on 1 January 2023. From this date, it is mandatory for all ships to calculate their attained Energy Efficiency Existing Ship Index (EEXI), to measure their energy efficiency, and to start collecting data to report their annual operational Carbon Intensity Indicator (CII) and CII rating. This statutory news summarizes the …

EEXI implementation. The attained EEXI must be calculated for the individual ship, which fall under the regulation. The required EEXI value is the maximum acceptable attained EEXI value. The required EEXI value is determined by the ship type, the ship’s capacity and principle of …

The EEXI will be applicable to all vessels above 400 GT and falling under MARPOL Annex VI. Guidelines on calculations, surveys and verification of the EEXI will follow and be finalized at MEPC 76. Nevertheless, as the EEXI is the extension for existing ships of the newbuilding-related EEDI, most procedures will be the same as for the EEDI, with ...

PWind can directly be taken from the EEDI/EEXI technical file. Should installation of WAPS be post initial EEDI/EEXI certification, it needs to be newly calculated. The calculation of the reward factor that can be applied in the FuelEU calculation refers to the effective power calculation as defined in MEPC.1/Circ.896.

Digital EEXI tool – EEXI compliance in just a few steps. For all Ship Classification customers, DNV offers a fully digital ‘EEXI tool’, an easy-to-use self-service tool available via the Veracity – Fleet Status customer portal.

The EEXI has already been the subject of numerous discussions. Many interest groups are now trying to digest the effects and understand the way forward. They are looking for the answer to their question: “What should I do now?” This webinar explains important aspects of EEXI and cover the following: Regulatory situation

The Energy Efficiency Existing Ship Index (EEXI) applies many of the same design requirements as the EEDI, with some adaptations regarding limited access to design data. The intention of the EEXI regulation is to bring existing vessels to a similar efficiency standard as more modern ones. The EEXI will come into force in 2023.

A description of the permanent power limitation measure must always be attached to the EEXI Technical File and available for inspection. If an overridable power limitation is replaced by a permanent power limitation, such as after a propeller retrofit, the permanent power limitation report replaces the OMM.

The EEXI requirement came into effect on 1 January 2023, and all affected ships should now comply. To maintain compliance, any ship undergoing changes that affect its EEXI and/or EEDI may need to recalculate these. This statutory news outlines impacts on and necessary actions for energy efficiency certification following ship modifications. SHARE:
