IMO Requirements for Carriage of Publications on Board Ships

Introduction

The International Maritime Organization (IMO) has established a series of mandatory publications that must be carried on board every vessel subject to the International Convention for the Safety of Life at Sea (SOLAS) and other relevant conventions. These documents provide guidance, technical data, and legal references necessary for safe navigation, emergency response, and compliance with international rules.

Failure to have the required publications on board can lead to operational delays, legal sanctions, and unsafe conditions. This page summarises the core IMO requirements, the key publications involved, the parties responsible for maintaining them, and practical steps for shipowners and operators.

Legal Framework

The requirement to carry specific publications is embedded in a number of IMO instruments, primarily:

• SOLAS 1974, Chapter V Safety of navigation, Chapter VII Fire protection, Chapter IX Management for the safe carriage of cargoes.
• IMO Instruments related to specific hazards International Convention for the Prevention of Pollution from Ships (MARPOL), International Convention on Standards of Training, Certification and Watchkeeping (STCW).
• Resolution MSC.232(84) Mandatory carriage of the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code) and the International Maritime Dangerous Goods (IMDG) Code.
• Resolution MSC.267(84) Updates to the International Safety Management (ISM) Code publication requirements.

Each Convention or Code contains annexes that list the publications that must be carried on board, the language(s) in which they must be available, and the method of distribution (paper, electronic or both).

Responsibilities for Carriage and Maintenance

Verification, Updates and Electronic Formats

IMO recognises the practical advantages of electronic publications. However, electronic versions must:

• Be stored on a secure, nonremovable media (e.g., CDROM, USB with readonly protection) or a validated ECDIS/Document Management System.
• Be accessible offline satellite connectivity cannot be assumed at sea.
• Contain a clear indication of the latest amendment date and version number.
• Be regularly crosschecked against the IMOs e-Navigation portal or the official IMO website for updates.

Paper copies remain the fallback format if electronic media fails. The master copy on board must be the most uptodate edition; older versions must be removed or clearly marked Superseded.

Penalties and Enforcement

Noncompliance can lead to:

• Detention of the vessel by Port State Control.
• Fines imposed by the flag State or coastal State authorities.
• Increased insurance premiums or loss of cover.
• Potential liability in the event of an incident where missing publications contributed to loss of life or environmental damage.

In severe cases, repeat offenders may face charterer bans and restrictions on sailing to certain ports.

BestPractice Checklist for Operators

1. Catalogue Every Required Publication Use a spreadsheet that lists title, latest amendment date, language, format (paper/edoc), and storage location.
2. Set a Calendar Reminder Schedule quarterly checks against IMO circulars, updating any outofdate items.
3. Implement Version Control Label each copy with Current and retain a log of replaced versions for audit purposes.
4. Train the Crew Conduct a brief training session during each muster drill on where the publications are stored and how to retrieve them.
5. Test Electronic Access Perform a dry run to open each edocument on the ships IT system; verify no password or network issue blocks access.
6. Document the Inspection The Master signs a Publications Log after each survey; keep a copy in the ships safety folder.
7. Backup Critical Documents Store a secondary set on a sealed, waterproof container in a separate location on board.
