Applicability: shipowners, ship operators and ship managers. 

IMO DCS (Data Collection System) Requirements

As first reported in Class News 01/2017 and later updated in Class News 33/2017, from 2020 onwards, ship operators of ships of 5,000GT and above engaged in international shipping are required to submit annual fuel oil consumption data to their Flag Administration or a Recognised Organisation nominated by the Flag. 

Data for the 2020 reporting period must be submitted by the end of March 2021.

This data should be collected in accordance with the methodology described in the ship’s approved Ship Energy Efficiency Management Plan (SEEMP) Part II, and submitted with supporting evidence, to enable verification in line with Resolution MEPC.292(71). 

EU MRV (Monitoring, Reporting and Verification) Requirements

With reference to Class News 03/2019, owners and operators of ships greater than 5,000GT making commercial voyages into, out of or between EU ports are required to submit a verified emissions report to the European Commission. 

A verified emissions report must be submitted by 30 April in the year following the reporting period. 

As advised in Class News 24/2020, Lloyd’s Register (LR) has established a new accreditation with the Hellenic Accreditation System (E.SY.D) through Hellenic Lloyd’s S.A. (HLSA), which is a wholly owned subsidiary of Lloyd’s Register Group Limited. When submitting emission reports through the THETIS-MRV system, operated by the European Maritime Safety Agency (EMSA), please first make sure you request a new verifier partnership with HLSA, following the EMSA C06 guidance video (available here).

For more information about both regulations, please view our website here.

What should owners and operators do now?

Owners and operators should submit their fuel oil consumption data into LR’s CO2 Verifier platform, which can be accessed here. Submission of the data can be made using LR-provided templates available through CO2 Verifier or by following the templates in your approved Ship Energy Efficiency Management Plan (SEEMP) Part II.

It is strongly recommended that both IMO DCS & EU MRV submissions are made as soon as possible to provide sufficient time to identify any errors or misstatements.

The data should be supplemented by an ‘evidence pack’ of supporting information to enable the verification work to be completed. Details of what should be included in the evidence pack are provided in the help sections of the CO2 Verifier platform. When the supporting evidence is prepared, it can be bulk uploaded into CO2 Verifier and verification work by our technical staff can begin. 

If you require any support with use of, or access to, CO2 Verifier, please contact or use the help functionality built into the platform. 

For guidance on the use of THETIS-MRV and the steps involved with submitting an emissions report, please refer to the step-by-step videos available on the EMSA website.
