Data collection system for fuel oil consumption of ships

Amendments to MARPOL Annex VI on Data collection system for fuel oil consumption of ships, adopted by resolution MEPC.278(70), entered into force on 1 March 2018.

Under the amendments, ships of 5,000 gross tonnage and above are required to collect consumption data for each type of fuel oil they use, as well as other, additional, specified data including proxies for transport work.  The aggregated data is reported to the flag State after the end of each calendar year and the flag State, having determined that the data has been reported in accordance with the requirements, issues a Statement of Compliance to the ship.  Flag States are required to subsequently transfer this data to an IMO Ship Fuel Oil Consumption Database.  IMO will be required to produce an annual report to MEPC, summarizing the data collected.

In addition, on or before 31 December 2018, in the case of a ship of 5,000 gross tonnage and above, the Ship Energy Efficiency Management Plan (SEEMP) shall include a description of the methodology that will be used to collect the data and the processes that will be used to report the data to the ship's flag State.

IMO Ship Fuel Oil Consumption Database has been launched as a new module within the Global Integrated Shipping Information System (GISIS) platform and that Member States now have access to the Database (Circular Letter No.3827).

In order for uniform and effective implementation of the regulations, the following guidelines/circular were developed by MEPC:

  • 2016 Guidelines for the development of a Ship Energy Efficiency Management Plan (SEEMP) (resolution MEPC.282(70));
  • 2017 Guidelines for Administration verification of ship fuel oil consumption data (resolution MEPC.292(71));
  • 2017 Guidelines for the development and management of the IMO Ship Fuel Oil Consumption Database (resolution MEPC.293(71));
  • MEPC circular on submission of data to the IMO data collection system of fuel oil consumption of ships from a State not party to MARPOL Annex VI (MEPC.1/Circ.871/Rev.1); and
  • Sample format for the confirmation of compliance pursuant to regulation 5.4.5 of MARPOL Annex VI (MEPC.1/Circ.876).

Accessing the IMO Ship Fuel Oil Consumption Database in GISIS

Fuel oil consumption data can only be submitted by the Administration or an organization authorized by the Administration to submit data on their behalf.

During the early discussions on the IMO Data Collection System (DCS), IMO's Marine Environment Protection Committee agreed that data collected by the Organization, particularly related to transport work, needed to be confidential and not publicly available (MEPC 68/21, paragraph 4.12). In October 2016, the Committee (MEPC 70) adopted amendments to Annex VI of the MARPOL Convention establishing a mandatory data collection system for ship fuel oil consumption. The new regulation 22A states that the IMO Secretariat would provide an annual report on the data collected to MEPC, while "Parties" (governments that have ratified MARPOL Annex VI) shall have access to the data of all ships in an anonymized format strictly for their analysis and consideration.

Timeline for submitting data to the IMO Ship Fuel Oil Consumption Database in GISIS

In accordance with regulations 6.6, 6.7 and 22A of MARPOL Annex VI, Administrations or organizations authorized to act on their behalf are required to verify the reported annual fuel consumption data of their ships of 5,000 GT and above, and issue a Statement of Compliance by 31 May at the latest. In the event of the transfer of a ship from one Administration and/or company to another, upon receipt of reported data the Administration or any organization duly authorized by it shall promptly determine whether the data has been reported in accordance with regulation 22A and, if so, issue a Statement of Compliance. Not later than one month after issuing the Statement of Compliance, the Administration or authorized organization shall transfer that reported data to the IMO Ship Fuel Oil Consumption Database in GISIS.

In line with the above, Member States and/or authorized organizations are kindly reminded to submit the verified fuel oil consumption data of their fleet for the previous calendar year to GISIS at their earliest opportunity, and by 30 June at the latest.


MEPC 67 (October 2014) agreed, in principle, to develop a data collection system for ships and, following deliberations in a working group, agreed on the general description of the data collection system for fuel consumption of ships, including its core elements as follows: data collection by ships, flag State functions in relation to data collection and establishment of a centralized database by the Organization.

MEPC 68 (May 2015) agreed that development of a data collection system for ships should progress and follow a three-step approach: data collection, data analysis, followed by decision-making on what further measures, if any, are required.

MEPC 70 (October 2016) adopted mandatory MARPOL Annex VI requirements for ships to record and report their fuel oil consumption, by resolution MEPC.278(70).
