In June 2021, the 76th session of the Marine Environmental Protection Committee of the International Maritime Organization (MEPC76) approved the amendments to MARPOL Annex VI. Mandatory goal-based technical and operational measures to reduce carbon intensity of international shipping will be enforced. A new era of shipping carbon intensity is coming.
The amendment requires that the attained EEXI (Energy Efficiency Existing Ship Index ) of all operating ships of 400GT and above (consistent with EEDI ship type and size) must meet the required EEXI which equal to the required EEDI corresponding to April 1,2022 at the first annual, intermediate or renewal survey in 2023 (coordinated with the IAPP certificate, whichever is the first); Since January 1, 2023, all ships with 5000GT and above (consistent with EEDI ship type and size) will be subject to annual carbon intensity index (CII) calculation and rating (grade A to E, indicating a major superior to inferior performance). For ships rated as D for 3 consecutive years or rated as E, the SEEMP shall be reviewed to include a plan of corrective actions to achieve the required annual operational CII.
China Classification Society participated in the amendment of Annex VI of MARPOL convention. In the process of amendment, we have worked closely with the shipping industry to carry out fleet EEXI/CII assessment for domestic and foreign customers for more than 2000 ships. Meanwhile, according to the common problems found in the evaluation, we put forward and insisted on the revision suggestions of the guidelines at the meeting, responded to the concerns of shipowners and safeguarded the rights and benefit of shipowners.
Based on the amendment to MARPOL Annex VI, which reduces the carbon intensity of international shipping, combined with the accumulated practical experience in calculation and evaluation, CCS continues to provide a package of solutions for the industry, with joint technical services provided by Science and Technology Innovation and Test Center of headquarter, Shanghai Rules & Research Institute and relevant branches, including:
1）Calculation, evaluation and pre-verification of technical energy efficiency (EEXI) of ships / fleets;
2）Calculation, rating and pre-verification of ship / fleet operational energy efficiency (CII);
3）EEXI / CII comparative analysis of corresponding ship types of ship / fleet;
4）Technologies and measures to improve EEXI and CII of ships, as well as their evaluation and verification, include:
(1) Evaluation and verification of speed and power (model,digital calculation, etc.) of non-EEDI ships;
(2) Evaluation and verification of energy saving devices (power system and hydrodynamic system, etc.);
(3) Design and effect evaluation of power reduction scheme.
5）Consultation and training on shipping carbon intensity rules, including:
(1) EEXI/ CII requirements;
(2) EEXI/ CII calculation;
(3) The impact of EEXI/ CII on operating ships and ship operation;
(4) Measures to improve EEXI/ CII of ships.
It is a new task for the shipping industry to improve the market competitiveness of ships and further promote the green and low-carbon development basing on the new value evaluation standards. China Classification Society is willing to join hands with the industry to welcome the era of shipping carbon intensity.
