Most merchant ships primarily burn fuel oil to produce power for
propulsion purposes, electrical power generation, boilers, or all of these. But any misuse of fuel oil can lead to major claims and jeopardize the safety of
the ship. The purpose of this article is to provide masters, ships' chief engineer and shore
superintendents with a basic understanding of the use of, and precautions to
be taken when using fuel oils on board ship and how to keep a proper oil record book entry. Marpol 73/78 required when any oil-handling work is carried out, the Master, Chief Officer, and Chief Engineer enter the facts in the Oil Record Book and sign the same according to below procedures.
Keeping Oil Record Book:
The Master shall keep on board the following Oil Record Books required by laws and regulations -
Oil Record Book for tankers (cargo and ballast operations) and
-
Oil Record Book for all ships (machinery space operations).
Persons Who Will Sign Entries In Oil Record Book: -
For oil tankers chief officer and for other ships chief engineer .
-
Each completed page shall be countersigned by the Master
Disposal To Reception Facilities In Harbour
Tank washings, Dirty ballast water, Residues, or Oily mixtures are discharged to reception facilities in a harbor for disposal; the Master shall obtain from the facility, the receipt or certificate which states the receiving date and the received quantity (with a supplementary note in English). And keep it on board attaching to the Oil Record Book to prove the fact of the disposal ashore.
Language to be Used : English (recognized worldwide)
Keeping Oil Record Book:
The Master shall retain the Oil Record Books on board for three years after the day of the last entry, and these should be readily available for any inspections.
Handling Note (Machinery part – All ships):
This is to record the quantity retained, transferred, disposed, or added, sludge, or bilge in the various drain or collecting tanks in Engine Room.
This can be the data for entry in the Oil Record Book and information for a supplementary explanation at an inspection.
Handling notes are to be preserved on board for three years after the day of the last entry.
Records Of ODMCS (Tankers) :
When Vessel is discharging, an oily mixture to sea, the Chief Officer shall operate the Oil Discharge Monitoring and Control System (ODMCS). It shall record the discharging of effluent and opening/closing of the overboard discharging valve by this system.
The Chief Officer should keep the records for three years after the day of the last entry.
Rules For Reference:
- MARPOL 73/78 as amended
-

Guidance for recording of operations in the oil record book Part 1 - Machinery space operations ( all ships)
Operations should be recorded in chronological order as they have been executed on
board.
- Dates should be entered in dd/mm/yyyy format, e.g. 16-MAR-2009.
-
Incineration or landing ashore of oily garbage and used filters should be recorded in the
Garbage Record Book only.
- All Entries are to be made and signed by the officer or officers in charge of the
operations concerned, and each completed page shall be signed by the Master of the
ship.
- Do not leave any full lines empty between successive entries.
- If a wrong entry has been recorded in the Oil Record Book (ORB), it should immediately
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.
- Tank nomenclature should be recorded as per the format noted within the International
Oil Pollution Prevention Certificate (IOPPC).
- Recording of quantities retained in bilge water holding tanks listed under section 3.3 of
the IOPPC is voluntary and not required by the Convention.
- The recording of general maintenance of items pertaining to the OWS remains
voluntary and is not required to be recorded in the ORB.
-
Usage of code C.11: Collection of oil residues (sludge).
Example #1

the IOPPC)
- Example #2 :
Recording of oil residue (sludge) collected by manual operation in oil residue (sludge) tank- Note: Operator initiated manual collection where oil residue (sludge) is transferred (transfer
with a pump) into the oil residue (sludge) tank(s). Examples of such operations could
be:
1. Collection of oil residue (sludge) from fuel oil separator drain tanks.
2. Collection of oil residue (sludge) by draining engine sump tanks.
3. Adding fuel oil to an oil residue (sludge) tank (all content of a sludge tank is
considered sludge).
4. Collection of sludge from bilge water holding tanks – in this case a disposal
entry for bilge water is also needed.
-
Usage of code C.12: Disposal or Transfer of oil residues (sludge)
Example #3:
Disposal of oil residue (sludge) via shore connection
Note: Ships' masters should obtain from the operator of the reception facilities, which includes
barges and tank trucks, a receipt or certificate detailing the quantity of oil residue
(sludge) transferred, together with the time and date of the transfer. This receipt or
certificate, if attached to the Oil Record Book Part I, may aid the Master of the ship in
proving that his ship was not involved in an alleged pollution incident. The receipt or
certificate should be kept together with the Oil Record Book Part I.
-
Example #4:
Draining of water (disposal) from an oil residue (sludge) tank listed under item 3.1 in the
Supplement to the IOPPC, to a bilge water holding tank listed under item 3.3 in the Supplement
to the IOPPC :
Note: Collection of bilge water need not be accounted for, so only one entry is required.
Capacity of sludge tanks should not be recorded for C.12.x entries.
