The IMO Data Collection System (DCS) introduces enhanced data granularity requirements for the reporting and verification of fuel oil consumption and operational data. These FAQs provide practical guidance on submitting the required data and supporting evidence to Lloyd’s Register.
FAQs
You can submit your IMO DCS data through LR Emissions Verifier. The submitted data should include all the information required under Appendix 4 of MEPC.395(82), as amended by MEPC.401(83) and MEPC.413(84).
If you don’t have access to Emissions Verifier, you can find out more about the service and contact us to request access here.
You need to submit the relevant supporting evidence alongside your IMO DCS data. You can find guidance on the documents required in LR’s Evidence Pack, also available through the Help section in LR Emissions Verifier.
I. The revised FOC Report consists of the aggregated data which consists of Vessel's Annual Total FO consumption Data, Total FO consumption per consumer and fuel type, FO consumption per consumer and fuel type (when not underway), Total distance travelled, Distance travelled (when underway & Not underway), Laden Distance, Hours Underway, Total amount of OPS, Transport Work, etc.
II. The Fuel Oil Consumption Report (FOCR) is to be submitted in the LR Emissions Verifier. This enables verification of compliance with IMO Data Collection System (DCS) requirements and supports the issuance of the Statement of Compliance (SoC).
Collected Data Summaries provide the operational detail needed to support and verify your annual reported data, including distance travelled, hours underway, fuel consumption and relevant voyage information. They should be prepared in line with Appendix 2 of IMO Resolution MEPC.389(81).
Find the details in the table below
| Item | Description |
| Date and Time of Event | Date and time of each event during the reporting period (From / To). |
| Distance Travelled | Distance travelled for each event, segregated into Underway and Not Underway periods. |
| Hours Underway | Total hours the vessel was underway during the event. |
| Cargo Carried (as applicable) | Cargo carried during the event, reported in the applicable unit as shown below. |
|
(i). MT (Metric Tonnes) |
For tankers, bulk carriers, gas carriers, general cargo ships, and other cargo vessels, report the total cargo carried in metric tonnes (t). |
| (ii). TEU | For container ships, report the total number of loaded containers expressed in Twenty-foot Equivalent Units (TEU). |
| (iii). Passengers | For passenger ships, report the total number of passengers carried. |
| Exceptional Conditions | Indicate whether the vessel operated under exceptional conditions exempted under MARPOL Annex VI Regulation 3.1 (Y/N). |
| Sailing in Ice Conditions | Indicate whether the vessel navigated in ice-covered waters during the reporting period (Y/N). |
| STS Operations | Indicate whether Ship-to-Ship (STS) transfer operations were conducted during the reporting period (Y/N). |
| Total Fuel Oil Consumption by Fuel Type | Total fuel oil consumption reported separately for each fuel type (e.g. HFO, LFO, MDO/MGO, etc.). |
| Fuel Oil Consumption by Consumer Type | Fuel oil consumption by fuel type for each consumer category, such as Main Engine (ME), Auxiliary Engine (AE), Fired Boilers, and Others. |
| Deductible Fuel Consumption | Fuel quantities to be deducted from the total fuel consumption, reported by fuel type (e.g. Fc electrical, Fc boiler & Fc others). |
| Underway Events | Not Underway Events |
| COSP/FAOP to EOSP | EOSP to Berth/Anchor/STS Operations |
| At Berth | |
| During STS Operations | |
| At Anchor | |
| Berth to COSP/FAOP | |
| Canal Passage |
To support verification, please provide evidence covering at least two voyages during the reporting period. This may include Daily Noon Reports, Arrival and Departure Reports, Deck or Engine Room Logbook entries, or VPMS log extracts.
The evidence required depends on the data collection methodology approved in your SEEMP Part II. Note that evidence should cover at least two Underway and two Not Underway events and clearly demonstrate the fuel consumption associated with each consumer and fuel type. For more information review the table below.
| Methodology | Underway Events | Not Underway Events |
| Flowmeter Method (MEPC.395(82), Paragraph 7.3.1) | Evidence: Deck Logbook, ER Logbook, Noon Reports, Arrival Reports, Departure Reports. | Evidence: Deck Logbook, ER Logbook, Noon Reports, Arrival Reports, Departure Reports. |
| Bunker Tank Monitoring Method (MEPC.395(82), Paragraph 7.3.2) | ||
| Subtraction Method (MEPC.395(82), Paragraph 7.4.2) | ||
| Estimation Method (MEPC.395(82), Paragraph 7.4.1) | Evidence: Noon Reports, ER Logbook entries, or equivalent onboard calculation records demonstrating: • Operating hours • SFOC • Consumer kW rating (where applicable) • Number of consumers in operation (ME, AE, Boilers, Others) |
