IMSML Web Article 17/2026: Malaysian Shipping Notice (MSN) 06/2025 Introducing Resolution MEPC.403(83) - Amendments to the 2022 Guidelines on Survey and Certification of the Energy Efficiency Design Index (EEDI) - The Regulations: Regulations 1-29 (Parts 1 of 3)

Resolution MEPC.403(83) was adopted by the Marine Environment Protection Committee (MEPC) at its 83rd Session on 11 April 2025. This Resolution was introduced into Malaysia via MSN 06/2025 by the Director of Marine on 9 October 2025.

Resolution MEPC.403(83) was a response to Regulation 5 on Surveys under MARPOL Annex VI (as amended) as Chapter 3 is subject to survey and certification taking into account IMO Guidelines. The 2022 Guidelines on Survey and Certification of the Energy Efficiency Design Index (EEDI) can be traced by to Resolution MEPC.365(79) as amended by Resolution MEPC.374(80).

What is in the new Paragraph 4.3.5?

Measurement of sea conditions should be in accordance with ITTC Recommended Procedure 7.504-01-01.1., titled ‘Preparation, Conduct and Analysis of Speed/Power Trials or ISO 15016: 2025’.

What are the new Ship Speed Measurement provisions in Paragraph 4.3.6?

Measurements should be made in accordance with ITTC Recommended Procedure 7.5-04-01-0.1.1 titled ‘Preparation, Conduct and Analysis of Speed/Power Trials 2024, or ISO 15016: 2025’. Measurements should be made at more than two point of which range includes the power of the main engine (ie as specified in Paragraph 2.2.5 of the EEDI Calculation Guidelines).

What is new about the development of Power Curves in Paragraph 4.3.8?

Development of power curves should be based on the measured ship speed and the measured output of the main engine at sea trial. This should be based on calibrated measured ship speed. If necessary, this should take into account the effects of wind, current, waves, shallow water, displacement, water temperature and water density, ie in accordance with ITTC Recommended Procedure 7.5-04-01-01.1 titled ‘Preparation, Conduct and Analysis of Speed/Power Trials 2024, or ISO 15016: 2025’. This will then be submitted to the verifier for verification.

What is the Goal of the Regulations on Carbon Intensity?

Reduce carbon intensity and implement the IMO Strategy on Reduction of GHG emissions from Ships, see Regulation 20.

When Must the Attained Energy Efficiency Design Index (Attained EEDI) be Calculated?

It is required for the following:

[1] Each new ship, see Regulation 22.1.1;

[2] Each new ship which has undergone a major conversion, see Regulation 22.1.2;

[3] Ships that have undergone a conversion so extensive that it is regarded by IMO as a new ship, see Regulation 22.1.3.

What is the Attained Energy Efficiency Existing Ship Index (Attained EEXI)?

It indicates the estimated performance of the ship in terms of energy efficiency to each specific ship, showing the process of calculation and verification, see Regulation 23.1. It has to be calculated for each ship (see Regulation 23.1.1) and each ship which has undergone a major conversion (see Regulation 23.1.2).

What is the Required EEDI?

The Attained EEDI has to be equal to or less that the Required EEDI, see Regulation 24.1. This is calculated by taking 1 and minus the value of X/100, multiply by the Reference Line Value, see Regulation 24.1.

Note, that X is the Reduction Factor provided in Table 1, see Regulation 24.2. The values here are calculated according to ship type such as:

[a] Bulk carrier;

[b] Gas carrier;

[c] Tanker;

[d] Containerships;

[e] General cargo ships;

[f] Refrigerated cargo carrier;

[g] Combination carrier;

[h] LNG carrier;

[i] Ro-rp cargo ship (vehicle carrier);

[j] Ro-to cargo ship;

[k] Ro-to passenger ship;

[l] Cruise passenger ship (having non-conventional propulsion).

Note, Table 2 shows how the reference parameters are derived for the different ships, see Regulation 24.3.

What is the Required EEXI?

This is calculated when one minus from 1 the value of y/100, multiplied with the EEDI reference line value. There is now an additional Table 3 which provides reduction factors (in percentage) for the EEXI relative to the EEDI reference line, which varies according to ship type, see Regulation 25.1.

What is the Ship Efficiency Management Plan (SEEMP)?

For ships constructed on or before 1 January 2023, the SEEMP shall include the following under Regulation 26.3.1:

[1] Calculation methodology;

[2] Annual operational CII for the next three years;

[3] Implementation plan;

[4] Self-evaluation and improvement procedure.

Note, both [3] and [4] above are subject to verification and audits see Regulation 26.5.

The methodology for ships constructed on or before 1 January 2028 under Regulation 26.4.1 is similar, but minus the implementation plan and self-evaluation / implementation procedure.

How is the Ship’s Fuel Oil Consumption Data Collected and Reported?

After the first data set, data is to be collected each subsequent calendar year or portion thereof in accordance with the declared methodology, see Regulation 27.1. Generally, the data is collected in the calendar year or proration thereof and aggregated, see Regulation 27.2.

Generally, reporting is to be performed within three months at the end of each calendar year, ie the aggregated value for each datum via electronic communication as specified by IMO, see Regulation 27.3. Disaggregated data is however allowed when there is a change of the ship from one company to another, for the calendar year corresponding to that company, see Regulation 27.5. The disaggregated data from the previous calendar year shall be accessible for a period of not less than 12 months from the end of the calendar year and made available to IMO upon request, see Regulation 27.8.

The reported data are submitted to IMO’s Ship Fuel Oil Consumption Database, and the Secretary General produces an annual report summarising the data, status of missing data and other relevant information, see Regulation 27.10. Parties have access to a non-anonymised database containing data for all ships which are regulated, for the purposes of analysis and consideration, see Regulation 27.12. By contrast, an anonymised database (ie where the identification of a specific ship will not be possible), is available to public user accounts, see Regulation 27.13. The data may be shared with analytical consultancies and research entities under strict confidentiality rule, see Regulation 27.15.

What is Operational Carbon Intensity?

Applicable carbon intensity (CII) calculated annually from 1 January to 31 December for the preceding calendar year (over a 12-month period), for ships above 5,000 gross tonnage, post-2023, see Regulation 28.1. This data is to be transmitted to IMO via electronic communication in the standardised format to IMO, see Regulation 28.2..

The Required Annual Operational CII, calculated with first determining the value of 1 minus the annual reduction factor (to ensure continuous improvement of the ship’s operational carbon intensity within a specified rating level) divided by 100. Then this value is multiplied by CIIR, the reference value, see Regulation 28.4.

Operationally, the CII is rated A, B, C, D or E, indicating a major. superior, minor superior, moderate,minor inferior or inferior performance level, see Regulation 28.6. Level C is the mid-point and is the minimum required annual operational CII, see Regulation 28.6. Therefore, a ship rated as D for three consecutive years or rated E shall duly undertake planned corrective actions in accordance with revised SEEMP, see Regulation 28.9.

Is there Promotion of Technical Cooperation and Transfer of Technology relating to the Improvement of Energy Efficiency of Ships?

YES … This is done pursuant to Regulation 29.
