with the Secretary's regulations. Note that the Oil Record Book is o n e book with two parts; Machinery Space
Operations is under Part I and Cargo/Ballast Operations is under Part II.
Each oil tanker of 150 gross tons and above, ship of 400 gross tons and above other than an oil tanker, and
manned fixed or floating drilling rig or other platform shall maintain an Oil Record Book Part I (Machinery Space
Operations). An oil tanker of 150 gross tons and above or a non oil tanker that carries 200 cubic meters or more
of oil in bulk, shall also maintain an Oil Record Book Part II (Cargo/Ballast Operations).
Oil Record Books printed by the U.S. Government are available to the masters or operators of all U.S. ships
subject to 33 CFR 151.25, from any Coast Guard Sector Office, Marine Inspection Office, or Captain of the Port
Office.
An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a valid OMB control

OIL RECORD BOOK
PART I - Machinery Space Operations
(All Ships)
INSTRUCTIONS FOR ALL SHIPS
Each oil tanker of 150 gross tons and above, ship of 400 gross tons and above other than an oil tanker, and manned
fixed or floating drilling rig or other platform shall maintain an Oil Record Book Part I (Machinery Space
Operations). 33 CFR 151.25 (a)
The following pages of this section show a comprehensive list of items of machinery space operations which are,
when appropriate, to be recorded in the Oil Record Book Part I (Machinery Space Operations) in accordance with
regulation 17 of Annex I to MARPOL 73/78 and implemented in 33 CFR 151.25. The items have been grouped
into operational sections, each of which is denoted by a letter Code.
When making entries in the Oil Record Book Part I, the date, operational code, and item number shall be inserted
in the appropriate columns and the required particulars shall be recorded in chronological order as they have been
executed on board. Each operation shall be fully recorded without delay so that all the entries in the book
appropriate to that operation are completed. Each operation should be dated in the dd-MONTH-yyyy format (e.g.
20- JAN-2011). Each Completed operation shall be entered and signed by the officer/person or
officers/persons 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
(IOPP) Certificate.
The Oil Record Book Part I contains many references to oil quantity. The limited accuracy of tank measurement
devices, temperature variations and c1ingage will affect the accuracy of these readings. The entries in the Oil
Record Book Part I should be considered accordingly. All quantities should be consistently recorded
throughout the Oil Record Book as cubic meters, gallons, or barrels.
In the event of accidental or other exceptional discharge of oil, statement shall be made in the Oil Record Book
Part I of the circumstances of, and the reasons for, the discharge.
Any failure of the oil filtering equipment shall be noted in the Oil Record Book Part I.
The entries in the Oil Record Book Part I for ships holding an IOPP Certificate shall be in English.
The Oil Record Book Part I shall be kept in such a place as to be readily available for inspection at all reasonable
times and, except in the case of unmanned ships under tow, shall be kept on board the ship. It shall be preserved
for a period of three years after the last entry has been made.
The competent authority of the Government of a Party to the Convention may inspect the Oil Record Book Part I
on board any ship to which Annex I applies while the ship is in its port or offshore terminals and may make a copy
of any entry in that book and may require the master of the ship to certify that the copy is a true copy of such entry.
Any copy so made which has been certified by the master of the ship as a true copy of an entry in the Oil Record
Book Part I shall be made admissible in any juridical proceedings as evidence of the facts stated in the entry. The
inspection of an Oil Record Book Part I and the taking of a certified copy by the competent authority under this
paragraph shall be performed as expeditiously as possible without causing the ship to be unduly delayed.
Selected excerpts of MARPOL 73/78 and 33 CFR 151 regulations pertaining to oil discharge and Oil Record Book
standards are provided in the appendix found at the end of this Oil Record Book.

Each oil tanker of 150 gross tons and above or a non oil tanker that carries 200 cubic meters (m3) or more of oil in
bulk, shall also maintain an Oil Record Book Part II (Cargo/Ballast Operations) in addition to an Oil Record Book
Part I. 33 CFR 151.25 (a)
The following pages of this section show a comprehensive list of items of cargo and ballast operations which are,
when appropriate, to be recorded in the Oil Record Book Part II in accordance with regulation 36 of Annex I to
MARPOL 73/78 and implemented in 33 CFR 151.25. The items have been grouped into operational sections. each
of which is denoted by a code letter.
When making entries in the Oil Record Book Part II, the date, operational code and item number shall be inserted
in the appropriate columns and the required particulars shall be recorded chronologically in the blank spaces. Each
operation shall be fully recorded without delay so that all the entries in the book appropriate to that operation are
completed. Each operation should be dated in the dd-MONTH-yyyy format (e.g. 20- JAN-2011). Each
Completed operation shall be entered and signed by the officer/person or officers/persons 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.
In respect of the oil tankers engaged in specific trades in accordance with regulation 2.5 of Annex I of MARPOL
73/78, appropriate entry in the Oil Record Book Part II shall be endorsed by the competent port State authority.
(This sentence should only be inserted for the Oil Record Book of a tanker engaged in a specific trade.)
The Oil Record Book Part II contains many references to oil quantity. The limited accuracy of tank measurement
devices, temperature variations and c1ingage will affect the accuracy of these readings. The entries in the Oil
Record Book Part II should be considered accordingly. All quantities should be consistently recorded
throughout the Oil Record Book as cubic meters, gallons, or barrels.
In the event of accidental or other exceptional discharge of oil, a statement shall be made in the Oil Record Book
Part II of the circumstances of, and the reasons for, the discharge.
Any failure of the oil discharge monitoring and control system shall be noted in the Oil Record Book Part II.
The entries in the Oil Record Book Part II, for ships holding an IOPP Certificate, shall be in English.
The Oil Record Book Part II shall be kept in such a place as to be readily available for inspection at all reasonable
times and, except in the case of unmanned ships under tow, shall be kept on board the ship. It shall be preserved
for a period of three years after the last entry has been made.
The competent authority of the Government of a Party to the Convention may inspect the Oil Record Book Part II
on board the ship to which Annex I applies while the ship is in its port or offshore terminals and may make a copy
of any entry in that book and may require the master of the ship to certify that the copy is a true copy of such entry.
Any copy so made which has been certified by the master of the ship as a true copy of an entry in the Oil Record
Book Part II shall be made admissible in any juridical proceedings as evidence of the facts stated in the entry. The
inspection of an Oil Record Book Part II and taking of a certified copy by the competent authority under this
paragraph shall be performed as expeditiously as possible without causing the ship to be unduly delayed.
Selected excerpts of MARPOL 73/78 and 33 CFR 151 regulations pertaining to oil discharge and Oil Record Book
standards are provided in the appendix found at the end of this Oil Record Book.
