What is EEXI?
What is EEXI?
The Energy Efficiency eXisting ship Index (EEXI) is a new IMO regulation that aims to reduce CO2 emissions of existing vessels by setting minimum requirements for technical efficiency. EEXI comes into force on 1 January 2023.
What is EEXI shipping?
Introduction of the Energy Efficiency Existing Ship Index (EEXI) During MEPC 76 in June 2021, the IMO adopted amendments to MARPOL Annex VI, introducing an Energy Efficiency Design Index for existing ships (EEXI). The EEXI is applicable for all vessels above 400 GT falling under MARPOL Annex VI.
What is Eedi and EEXI?
The EEXI is like its predecessor, the Energy Efficient Design Index (EEDI)—in effect since 2013—but applied to existing ships outside EEDI regulations. It specifically targets vessels above 400 GT that fall under MARPOL Annex VI. To set CO2 emissions standards, the EEXI uses the same methodology as the EEDI.
What is attained EEDI?
The attained EEDI is the actual calculated and verified EEDI value for an individual ship based on the data in the EEDI technical file. It shall be calculated for all ships of 400 GT and above. The attained EEDi must be below the ‘Required EEDI’ limit prescribed in MARPOL.
What is IMO DCS?
The International Maritime Organization (IMO) adopted a mandatory Fuel Oil Data Collection System (DCS) for international shipping, requiring ships of 5,000 gross tonnage or above to start collecting and reporting data to an IMO database from 2019. …
What is enhanced Seemp?
A strengthening of the SEEMP (Enhanced SEEMP) to include mandatory content, such as an implementation plan on how to achieve the CII targets, and making it subject to approval. Verification and audit requirements for the SEEMP will only apply to ships above 5,000 GT subject to the CII requirements.
How is Eedi calculated?
Energy Efficiency Design Index (EEDI), formulated for new ships, is an index that estimates grams of CO2 per transport work (g of CO2 per tonne-mile). It can be expressed as the ratio of “environmental cost” divided by “Benefit for Society”.
What is an emissions intensity ratio?
An intensity ratio is a way of defining your emissions data in relation to an appropriate business metric, such as tonnes of CO2e per sales revenue, or tonnes of CO2e per total square metres of floor space. SECR Intensity ratios are calculated by dividing your emissions by your organisation-specific metric.
How is EEDI calculated?
How can I improve my EEOI?
The most direct way to reduce the EEOI is therefore to reduce speed. The slow steaming that is widely practiced today is therefore a very efficient way of reducing energy consumption.
What is the unit of EEOI?
The Energy Efficiency Operational Indicator (EEOI) was developed by the IMO in order to allow ships to monitor the carbon emissions of their shipping activities. The EEOI is the total carbon emissions in a given time period per unit of revenue tonne-miles.
How can I reduce my EEOI?
Is the eexi based on the EEDI guideline?
EEXI calculation. The calculation of the EEXI follows the calculation of the well-known EEDI. It is based on the 2018 calculation guideline of the EEDI, with some adaptations for existing vessels. Currently, only draft guidelines are available (submission ISWG-GHG 7/2/7), which will be replaced by adopted guidelines after MEPC 76 in 2021.
When do you need to calculate eexi on a cruise ship?
The EEXI must be calculated for all cargo and cruise vessels above 400 GT falling under MARPOL Annex VI. In case of non-conventional propulsion (such as diesel-electric), please see MARPOL Annex VI for further clarification. In case of a major conversion, the EEXI must be recalculated.
How is the speed curve calculated for eexi?
EEXI calculation requires an accurate speed power curve for the loading conditions under the regulatory scope. Data to calculate an accurate speed curve may be difficult to obtain. For example, vessels built prior to 2013 had speed-power prediction for the design or ballast drafts, but not necessarily at scantling draft.
How long does it take to comply with eexi?
Many shipowners are either yet to commence the process or, in many cases, are only vaguely aware of the requirements. There is opportunity to get ahead of the game and prepare for a future of sustainability. Timeframes are short. There are several steps you may need to complete to achieve compliance.
