Each operation described above shall be fully recorded without delay in the Oil Record Book Part II, so that all entries in the book appropriate to that operation are completed.

Entries in the Oil Record Book are to be made in accordance with Regulation 36 of Annex I of MARPOL 73/78, as demonstrated in Appendix III of Annex I of MARPOL 73/78, Form of Oil Record Book, OIL RECORD BOOK PART II Cargo/Ballast operations, (Oil Tanker)

When making entries in the Oil Record Book, the date, operational code and item number shall be written in the appropriate columns and the required particulars shall be recorded chronologically in the blank spaces.

Each completed operation shall be signed for and dated by the officer in- Charge (As per section 3.0). Each completed page shall be signed by the master of the ship.




Guidance for Entries in the ORB Part 1 & Environmental Compliance procedures

  1. Dates should be entered in dd-MONTH-yyyy format, e.g. 12-MAR-2012;


  2. Incineration or landing ashore of oily garbage and used filters should be recorded in the Garbage Record Book only;


  3. All Entries are to be made and signed by the officer or officers in charge of the operations concerned. The Chief Engineer is to review the ORB on a daily basis and verify / countersign each entry. Each completed page shall be verified and signed by the Master of the ship;


  4. There must be no empty lines between successive entries;


  5. If a wrong entry is made in the Oil Record Book (ORB) it should be struck through with a single line in such a way that the wrong entry is still legible. The wrong entry should be signed and dated, with the new corrected entry following;


  6. Tank names and capacities must be recorded exactly as per the entries in the International Oil Pollution Prevention Certificate (IOPPC). The tanks and capacities in the IOPPC should also be checked to ensure they are correct as per the capacity plan and the actual tanks onboard - there have been a number of observations due to the mistakes made by class in the IOPP supplement.


  7. Although recording of quantities retained in bilge water holding tanks listed under section 3.3 of the IOPPC is voluntary, it is recommended to be recorded within the ORB.


  8. The recording of general maintenance of items relating to the OWS is also voluntary


  9. All MARPOL equipment and spares tagged as “critical” within the PMS are to be kept aligned with the Critical Equipment List and TEC 18 ”Minimum Critical Spares Inventory” approved by the Fleet Superintendent.


  10. It should be noted that USCG and PSC inspectors are now downloading data from the Oil Content Meters (OCM). This data is compared with the entries in the ORB so it is essential that times entered in the ORB are accurate.


  11. All MARPOL / “Magic Pipe” prosecutions in the USA have been successful based on false or inaccurate entries in record books (Oil, Garbage, Ballast & VGP), NOT THE ACTUAL ILLEGAL DISCHARGE.
