The 81st session of the Marine Environment Protection Committee (MEPC 81) is coming in two weeks. Document MEPC 81/6, the report of fuel oil consumption (FOC) data submitted to the IMO Ship Fuel Oil Consumption Database in GISIS (Reporting year: 2022), contains some interesting information on the data quality of the reports and the fuel distribution.

In 2022, a total of 28,834 ships reported their FOC data with a combined gross tonnage of 1,289 million gross tonnes. This represents a modest increase from the 28,171 ships and 1,255 million gross tonnes reported in 2021.

Data Quality - Errors/Findings from the fuel oil consumption reports of 2022:

Despite being the fourth reporting year for DCS, avoidable reporting errors have been identified.

July 2023

  • 283 ships with errors were identified.
  • 159 ships had instances of duplicate reporting, where the same data was reported more than once.
  • The remaining errors were due to incorrect ship characteristics, this included 57 ships which had reported an “hours under way” which was more than the number of hours in a year.

10 August 2023

  • corrective actions to reduce the errors identified in July 2023.
  • the number of identified errors, that could potentially have a large impact on aggregated data was reduced to 176 ships.
  • 74 ships were removed as they were duplicate reports.
  • 50 ships out of the aforementioned 176 ships were excluded because they had reported “hours under way” which were more than the total number of hours in a year
  • 9 ships that had an unrealistically large deadweight.

General notes

  1. Total fuel used by the reported ships was slightly higher during the 2022 reporting period when compared to the 2021 reporting period. The use of Liquefied Natural Gas decreased slightly when compared to 2021.
  2. When analysing the submitted data it was also found some fuel oil was reported incorrectly, such as VLSFO and LFO, under the “Other” fuel category.

  1. Fuels which were used during the 2022 reporting period that are not either Heavy Fuel Oil, Light Fuel Oil or Diesel/Gas Oil, represent 5.35% of the reported fuel oil in 2022 (compared to 6.05% of the reported fuel oil in 2021).

  1. The remaining fuel was reported under the “Other” fuel type category in GISIS. In the “Other” fuel type category, 95,204 tonnes of Ethane and 226,378 tonnes of biofuel were reported (67,580 tonnes in 2021). Biofuel was reported using a total of 32 different names of biofuel and biofuel blends (including B10MGO, B25HFO, B100MGO, Biofuel, HVO and Used Cooking Oil, etc.)

  1. During the reporting period the majority of fuel oil was consumed by three ship types; containerships, bulk carriers and tankers.

Note for the data submitters:

IMO has continued to improve the verification of submitted data and data submitters have also significantly improved their verification. Notwithstanding, data submitters are invited to pay attention to the following:

  1. It was found that some fuel oil was reported incorrectly, such as VLSFO and LFO, under the “Other” fuels category. This issue was rectified by moving these fuels to be under the Heavy Fuel Oil fuel category in-line with the Fourth IMO GHG Study 2020 in that the Low Sulphur Heavy Fuel Oil has the same emission factors as conventional HFO.
  2. Biofuel was reported using 32 different names. However, the overall amount of biofuel reported is small so this could still continue to be reported with a user defined name and CF factor under the “Other” fuels category pending future policy decisions concerning the application of the Guidelines on life cycle GHG intensity of marine fuels (LCA Guidelines) (resolution MEPC.376(80)).
