Reporting and verification

IMO DCS reporting

As for EU MRV, DNV GL will set up a DCS reporting process with the objective to minimize the efforts for the ship operator, mainly by using the existing reporting of fuel consumption commonly applied in the shipping industry. For vessels subject to both EU MRV and IMO DCS, the DNV GL reporting requirements will cover both schemes. For DNV GL customers currently subscribing to the ECO Insight service, the reporting requirements for the MRV and DCS are already covered and in place.


For MRV, the EU regulation requires a Monitoring Plan, while for the IMO DCS, a SEEMP Part II is required. To ensure compliance with the IMO requirements (see link below), DNV GL has established an electronic reporting form for this purpose. The form is available via My Services in our Veracity platform. When filled in, the same form can then be submitted to DNVGL for approval of the SEEMP Part II.

Verification of emission data

The verification process for IMO DCS was finalized at MEPC 71, however, the practical details of how and what to check as part of the verification within the DCS framework is up to the Flag and will be better defined as we get closer to 2019. But the basic principles are indicated in the figure:
