06《国际防止船舶造成污染公约》（MARPOL）附则VI修正案（低闪点燃料和其他燃油相关问题、船用柴油发动机替代蒸汽系统、可获取性以及船舶燃油消耗数据库（IMODCS）中运输工作量数据的纳入和增强粒度）
涉及决议
MEPC.385(81)
生效日期
2025年8月1日
主要内容
MARPOL附则VI修正案（MEPC.385(81)），修订内容涉及燃油定义、船用柴油机替代蒸汽系统、IMO DCS 数据的可访问性、IMO DCS 中纳入运输工作数据和提高粒度水平等。修正案将于2025年8月1日生效，考虑到CII数据完整性，对MARPOL附则VI附录IX关于IMO DCS修正案，建议各国提前自2025年1月1日起执行。
主要更新内容：
1、MARPOL附则VI第2、14条和附录I的修正案修订了气体燃料的定义，第18条修正案将加油记录单（BDN）要求适用于气体/低闪点燃料。使用气体或低闪点燃料的船舶成员建议确保加油记录单中包含最低限度的信息。 根据MEPC.385 ( 81 ) 决议，燃油是指交付给船上并在船上使用的任何燃料。而根据MEPC.328 ( 76 ) 决议，燃油原来的定义为“燃油系指为了船舶推进或运转而交付船上的用于燃烧的任何燃料，包括气体、馏分和残渣燃料”。此外，MARPOL公约附则VI新增第2.1.33条气体燃料定义，即气体燃料是指在温度为37.8 ℃时，蒸汽压力绝对值超过0.28 MPa的燃料。这两个定义的变化适应了目前船用替代燃料的发展趋势。
2、MARPOL附则VI第13.2.2条的修正案明确，用柴油发动机替代蒸汽系统被视为重大改装，而非小修改。如果需要安装TierIII发动机，但允许安装TierII发动机作为替代品，主管机关必须向国际海事组织报告。成员需要注意，在2025年8月1日这些修正案生效后，用船用柴油发动机替代蒸汽系统需要遵守MARPOL附则VI第13条及其修正案。
3、MARPOL附则VI第27条的修正案允许国际海事组织在严格保密且经公司同意的情况下，以非匿名形式将船舶燃油消耗数据与分析咨询公司和研究机构共享。
4、在附录IX中纳入运输工作量数据、细化数据种类，以支持有效和高效地审查CII规则和相关导则。
06 Amendment to Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL) (Low Flash Point Fuels and Other Fuel-related Issues, Replacement of Marine Diesel Engine Steam Systems, Accessibility and Incorporation of Transport Workload Data in the IMO Ship Fuel Consumption Database (IMODCS) and Enhancement of Granularity)
Resolutions Involved
MEPC.385(81)
Effective Date
August 1, 2025
Main Contents
The amendment to Annex VI of MARPOL (MEPC.385(81)) involves revisions to the definition of fuel oil, replacement of marine diesel engine steam systems, accessibility of IMO DCS data, incorporation of transport workload data into IMO DCS and improvement of the granularity level, etc. The amendment will come into effect on August 1, 2025. Considering the integrity of CII data, it is recommended that countries implement in advance as of January 1, 2025 the amendment to Appendix IX of Annex VI of MARPOL regarding IMO DCS.
Main Updates:
The amendments to Articles 2, 14 and Appendix I of Annex VI of MARPOL revise the definition of gaseous fuel, and the amendment to Article 18 applies the requirements of the Bunker Delivery Note (BDN) to gaseous/low flash point fuels. Shipowners using gaseous or low flash point fuels are recommended to ensure that the minimum information is included in the bunker delivery note. According to the MEPC.385(81) resolution, fuel oil refers to any fuel delivered on board and used on board. According to the MEPC.328(76) resolution, the original definition of fuel oil was "Fuel oil means any fuel delivered on board for combustion for the purpose of propulsion or operation of the ship, including gaseous, distillate and residual fuels". In addition, Article 2.1.33 of Annex VI of MARPOL newly defines gaseous fuel as fuel with an absolute vapor pressure exceeding 0.28 MPa at a temperature of 37.8 °C. These changes in the definitions adapt to the current development trend of alternative marine fuels.
The amendment to Article 13.2.2 of Annex VI of MARPOL clarifies that the replacement of a steam system with a diesel engine is regarded as a major modification rather than a minor modification. If it is required to install a Tier III engine but a Tier II engine is allowed to be installed as a substitute, the competent authority must report to the International Maritime Organization. Members need to note that after these amendments come into effect on August 1, 2025, the replacement of a steam system with a marine diesel engine shall comply with Article 13 of Annex VI of MARPOL and its amendments.
The amendment to Article 27 of Annex VI of MARPOL allows the International Maritime Organization to share ship fuel consumption data with analysis and consulting companies and research institutions in a non-anonymous form under strict confidentiality and with the consent of the company.
Incorporate transport workload data in Appendix IX and refine the types of data to support the effective and efficient review of the CII rules and relevant guidelines.

1）补充船用柴油机替代蒸汽系统的情况
2）制定了向IMO报告安装满足III级NOx限值非完全相同替代发动机不可行时而安装了II级发动机的报告模板；
3）邀请在2025年8月1日之前发现安装Tier III NOx限值发动机不可行的主管机关，使用该指南附录中规定的模板，将相关决定通知IMO。

Supplement the situation of replacement of marine diesel engine steam systems;
Develop a reporting template for reporting to the IMO when it is infeasible to install a non-identical replacement engine meeting the Class III NOx limits and a Class II engine is installed instead;
Invite the competent authorities that find it infeasible to install an engine meeting the Tier III NOx limits before August 1, 2025 to use the template specified in the appendix of the guidelines to notify the IMO of the relevant decisions.
