IMO Navigation and Search & Rescue – Paper Version

The IMO Navigation and Search & Rescue paper publications category at Nautic Way Maritime Bookshop brings together publications from the International Maritime Organization (IMO) dedicated to navigational safety, maritime communications, search and rescue at sea, and the coordination of search and rescue operations. These documents are international references for merchant navy officers, masters, crews, rescue coordination centres, maritime administrations, classification societies, inspectors, maritime training institutions and safety professionals.

Modern navigation relies on a combination of rules, procedures, equipment and professional skills. Safety does not depend solely on the accuracy of a position or the performance of electronic equipment. It also relies on the correct application of international regulations, effective communication procedures, the ability to prevent collisions and the efficient organization of rescue operations.

The IMO identifies SOLAS, COLREG and STCW among the main international conventions relating to navigational safety. Chapter V of SOLAS specifically addresses the safety of navigation and includes provisions relating to meteorological services, ship routing, search and rescue services and various navigation-related equipment and requirements.

IMO publications dedicated to navigation

Navigation safety is one of the major areas of activity of the IMO. The relevant publications cover navigation regulations, collision avoidance, ship routing, communications, electronic equipment and procedures used on board.

The IMO Navigation and Search & Rescue category may include documents relating to:

• navigational safety;

• international regulations for preventing collisions at sea;

• the Global Maritime Distress and Safety System, or GMDSS;

• maritime radiocommunications;

• radar and ARPA;

• electronic navigation;

• ship routing;

• traffic separation schemes;

• search and rescue procedures;

• the SAR Convention;

• the IAMSAR Manual;

• lifesaving appliances and equipment;

• training for personnel responsible for navigation and search and rescue.

The IMO officially includes Navigation and Search and Rescue among its publication areas, alongside GMDSS and lifesaving appliances.

COLREG: preventing collisions at sea

The COLREGs, or International Regulations for Preventing Collisions at Sea, are a fundamental reference for professional navigation.

These rules define the conduct to be followed when vessels meet, cross or overtake each other. They also regulate the use of lights, shapes and sound signals and establish requirements relating to lookout and the conduct of vessels.

Knowledge of COLREGs is essential for officers responsible for watchkeeping and navigation.

They apply equally to a container ship navigating the English Channel, a tanker crossing the North Sea, a bulk carrier operating in the Mediterranean or a commercial vessel crossing the Atlantic Ocean.

The IMO currently lists a 2026 edition of the COLREGs, illustrating the importance of checking the edition of the publication being used in a professional or training environment.

SOLAS and navigational safety

The SOLAS Convention – Safety of Life at Sea is one of the cornerstones of the international maritime safety framework.

Chapter V is dedicated to navigational safety. It covers meteorological services, ship routing, search and rescue services and various navigation-related equipment and requirements.

SOLAS also establishes requirements relating to communication and locating equipment. Chapter IV incorporates the GMDSS, including equipment such as EPIRB distress beacons and SART search and rescue transponders for vessels to which the requirements apply.

The 2024 Consolidated Edition of SOLAS is among the IMO publications currently available.

GMDSS: communications and safety at sea

The Global Maritime Distress and Safety System (GMDSS) is a key component of the international distress and rescue chain.

Its purpose is to enable rapid and reliable transmission of distress alerts and facilitate the communications required for search and rescue operations.

IMO publications relating to GMDSS may be particularly useful to:

• deck officers;

• radio operators;

• rescue coordination centres;

• maritime trainers;

• maritime administrations;

• professionals responsible for communication safety.

The IMO catalogue includes the GMDSS Manual, as well as publications relating to GMDSS distress alerts and operator qualifications.

Search and rescue at sea

When a vessel is in distress, the speed of the response depends not only on the available resources but also on the organization of the rescue operation.

The International Convention on Maritime Search and Rescue, 1979 (SAR Convention) establishes an international framework for organizing and coordinating search and rescue operations.

This organization relies in particular on RCCs, or Rescue Coordination Centres, and on international cooperation allowing available resources to be mobilized within a given area.

The IMO specifically identifies publications required by MRCCs and JRCCs, including the SOLAS Convention, the SAR Convention and the IAMSAR Manual.

The IAMSAR Manual

The IAMSAR Manual – International Aeronautical and Maritime Search and Rescue Manual is a major reference for the organization of search and rescue operations.

It is divided into several volumes dealing in particular with organization and management, mission coordination and mobile facilities involved in SAR operations.

The manual is intended for different maritime and aeronautical search and rescue stakeholders, including coordination centres, search and rescue mission coordinators, ships and aircraft participating in operations.

For a vessel operating in the North Atlantic, Mediterranean Sea or Indian Ocean, search and rescue procedures must be integrated into an internationally coordinated system.

The IMO currently lists the 2025 edition of Volume I of the IAMSAR Manual among its SAR-related publications.

Radar and ARPA navigation

IMO publications relating to radar, ARPA and search and rescue navigation complement general navigation regulations.

Radar enables targets to be detected and tracked regardless of visual visibility. ARPA helps analyse the relative movement of vessels and estimate parameters such as CPA and TCPA.

These systems are particularly important in areas with heavy maritime traffic.

A vessel entering Le Havre, crossing the English Channel or approaching Rotterdam may encounter dense traffic, converging routes, traffic separation schemes and changing weather conditions.

Radar and ARPA proficiency must therefore be combined with thorough knowledge of COLREGs and good watchkeeping practices.

The IMO includes training publications dealing with radar navigation, radar plotting, ARPA use and search and rescue navigation at management level.

Ship routing and traffic separation schemes

Navigational safety also depends on the organization of maritime traffic flows.

Traffic separation schemes, recommended routes and ship routing systems help structure vessel movements in areas that are particularly busy or sensitive.

The English Channel is a particularly significant example. Traffic between the North Sea and the Atlantic is extremely heavy, particularly near major European ports such as Le Havre, Rotterdam, Antwerp and Hamburg.

The IMO plays an international role in the approval and management of maritime ship-routing systems. Its Navigation, Communications and Search and Rescue Sub-Committee deals with technical matters relating to navigational safety and ship-routing measures.

International navigation and hydrographic documentation

IMO publications do not replace the hydrographic documents required for navigation.

A vessel navigating off the French coast may use official Shom documentation. For many international areas, Admiralty charts and publications are major references. Specialist publishers such as Imray and NV Charts also cover different navigation areas, particularly in Europe and selected ocean regions.

IMO publications provide another dimension: they establish the international rules and procedures within which navigation takes place.

Navigation in the Mediterranean Sea, North Sea, Atlantic Ocean, Indian Ocean or Pacific Ocean therefore requires both knowledge of the hydrographic environment and mastery of international safety regulations.

Essential documentation for maritime training

IMO Navigation and Search & Rescue publications also play an important role in the training of maritime professionals.

They may be used to support training in:

• steering and sailing rules;

• watchkeeping;

• radar and ARPA;

• GMDSS;

• radiocommunications;

• electronic navigation;

• maritime safety;

• SAR procedures;

• rescue coordination;

• survival techniques.

The STCW Convention establishes international standards for the training, certification and watchkeeping of seafarers. The IMO provides various training publications relating to navigation, radar, survival craft and survival techniques.

Why choose the paper version?

Paper format remains useful in professional maritime environments.

A printed publication can be:

• consulted immediately;

• annotated;

• used during training;

• kept in an onboard library;

• incorporated into regulatory documentation;

• consulted without a computer;

• used during meetings, audits or exercises.

For a training centre, maritime safety department or onboard technical library, a printed document provides a straightforward reference that can be consulted and retained over time.

International documentation for all oceans

Navigation and rescue know no borders.

A vessel leaving Saint-Nazaire may sail towards the Canary Islands, cross the Atlantic to the Caribbean and then continue towards the Panama Canal. Another may travel from Marseille to Singapore, crossing the Mediterranean, the Suez Canal, the Red Sea and the Indian Ocean.

Throughout these environments, international principles governing navigational safety, communications and search and rescue remain essential.

IMO documentation provides a common framework allowing crews, rescue centres and maritime administrations to work according to consistent international procedures.

Conclusion

IMO Navigation and Search & Rescue paper publications constitute essential reference documentation for the safety of commercial and professional navigation.

They cover key areas including COLREGs, SOLAS, GMDSS, maritime radiocommunications, radar, ARPA, ship routing, the SAR Convention, the IAMSAR Manual and search and rescue procedures.

They enable maritime professionals to understand the international rules governing navigation, communications and the organization of rescue operations at sea.

From the English Channel to the North Sea, from the Mediterranean Sea to the Atlantic, and from the Red Sea to the Indian and Pacific Oceans, these rules accompany vessels on major international shipping routes.

The paper format remains highly relevant for onboard libraries, training centres, maritime administrations, technical departments and professionals requiring official, structured and readily accessible maritime documentation.
