This publication provides guidance on proper and consistent completion of the Oil Record Book (Part II – Cargo/Ballast Operations) for oil tankers, as stipulated by Regulation 36 and Appendix III of Annex I of MARPOL 73/78. It sets out instructions and general requirements for making entries in the ORB Part II and lists the items that must be recorded. It also contains example entries for commonly used cargo/ballast operations.
This guide complements the INTERTANKO publication A Guide for Correct Entries in the Oil Record Book (Part I – Machinery space operations).
It provides simple and clear advice and guidance for making entries in the ORB Part II with the aim of:
- Ensuring compliance with the relevant MARPOL Annex I requirements
- Facilitating and simplifying the onboard work of the responsible officers and the Master
- Ensuring uniform and consistent ORB Part II recordkeeping that is aligned with and compatible with other shipboard logbooks and records.
It is structured in a user-friendly manner and can also be used both as an onboard guide and as a training tool for seafarers and shore-based personnel, including ship operators, surveyors and inspectors. It has also been designed to facilitate integration in the document management system of any individual Member of INTERTANKO.
1. Prologue
The INTERTANKO Safety and Technical Committee (ISTEC) has developed this Guide to assist ship operators in providing guidance to their seagoing personnel for the proper and consistent completion of the Oil Record Book (Part II – Cargo/ballast operations) (hereinafter referred to as ORB Part II), as stipulated by Regulation 36 and Appendix III of Annex I of MARPOL 73/78, as amended, thus minimising the risk for possible errors in logging information and record-keeping in the ORB Part II.
The Guide has been written to complement the INTERTANKO publication A Guide for Correct Entries in the Oil Record Book (Part I – Machinery space operations). It is structured in a user-friendly manner and it can also be used as a training or guidance tool for seafarers and shore-based personnel, including ship operators, surveyors and inspectors.
INTERTANKO would like to thank the members of the INTERTANKO Safety and Technical Committee for their support and to extend special thanks to Mr. Takis Koutris of Roxana Shipping for support in the review process.
INTERTANKO also wishes to thank all those who, over time, have provided invaluable feedback.
