The International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual will undergo a significant set of amendments. For shipowners, managers and masters, this update represents far more than a routine publication revision.
Instead, the changes directly affect how ships prepare for and conduct search and rescue (SAR) operations. They reflect an operational environment shaped by new technologies, revised GMDSS arrangements and increasingly complex offshore infrastructure.
Why the IAMSAR Amendments Matter
Under SOLAS Regulation V/21, every ship must carry an up-to-date copy of IAMSAR Manual Volume III. According to IMO guidance, this volume must be available in hard copy.
This requirement exists because the manual supports decision-making during emergencies. In such situations, digital systems may be degraded or unavailable. Therefore, crews must always have immediate access to reliable SAR guidance.
The latest amendments were adopted through IMO Circular MSC.1/Circ.1686. They will enter into force on 1 January 2026.
Regulatory Context and ISM Code Relevance
The amendments reflect recent developments in the Global Maritime Distress and Safety System (GMDSS). In addition, they address new SAR techniques and operational challenges linked to offshore renewable energy.
For companies operating under the ISM Code, these changes directly affect:
- Emergency preparedness arrangements
- Navigational and bridge procedures
- Training and drills for Masters and bridge teams
As a result, Safety Management Systems must evolve alongside the updated guidance.
Key Amendments at a Glance
The amendments apply to all three volumes of the IAMSAR Manual. However, Volume III, carried on board ships, has the most direct operational impact.
1. Alignment with the Revised GMDSS Framework
The manual now reflects the 2024 amendments to SOLAS GMDSS regulations. Consequently, SAR communications and coordination procedures align with the current distress and safety communication environment.
This alignment ensures consistency between shipboard actions, RCC coordination and modern GMDSS capabilities.
2. New Appendices Supporting State Cooperation
Several new appendices strengthen coordination between States and SAR authorities. These include:
- A sample memorandum of understanding (MoU) between SAR services and accident investigation authorities, clarifying responsibilities and information exchange after incidents.
- A sample approval process allowing SAR units from an assisting State to enter another State’s SAR region quickly.
As a result, cross-border cooperation can take place more efficiently when time is critical.
3. Enhanced Guidance for Night Search Operations
A new appendix introduces detailed guidance for night search operations conducted by aircraft. It focuses on the use of:
- Electro-Optic / Infrared (EO/IR) systems
- Night Vision Devices (NVDs)
In parallel, the amendments strengthen guidance for Rescue Coordination Centres (RCCs). This supports more effective planning and coordination of night searches using advanced technologies.
4. SAR Operations Near Offshore Wind Farms
The manual now includes a dedicated section addressing SAR operations in and around offshore wind farms and renewable energy installations.
Specifically, it covers:
- Hazards and restricted areas within wind farm clusters
- Coordination between ships, helicopters, service vessels and RCCs
- Communication protocols and access limitations in dense offshore infrastructure
Given the rapid expansion of offshore renewables, this guidance is particularly relevant for vessels trading in coastal and mixed-traffic zones.
5. Expanded Guidance on Flight Tracking Applications
The amendments also expand guidance on flight tracking systems and applications. These tools enhance situational awareness and support more accurate search planning.
This update reflects the growing availability of real-time tracking data for aviation assets involved in SAR operations.
Practical Implications for Shipowners and Masters
For many companies, the initial response may be to order the updated IAMSAR Volume III before the deadline. While necessary, this step alone is not sufficient.
To meet both SOLAS requirements and the intent of the ISM Code, companies should take a broader approach.
Review of Procedures and Documentation
Companies should review emergency response and SAR-related procedures within the Safety Management System. In particular, procedures should reflect updated guidance for:
- Night operations
- SAR scenarios near offshore wind farms
Bridge procedures and emergency manuals must remain consistent with the revised IAMSAR structure and terminology.
Checklists and Onboard References
Bridge checklists, COSPs, muster lists and emergency response checklists should be verified and updated. Any references to IAMSAR must align with the amended Volume III.
This step helps ensure that crews apply the correct guidance during drills and real emergencies.
Training and Drills
Training programs and drills should incorporate scenarios that reflect the new operational reality. These may include:
- Night searches involving aircraft and advanced sensors
- Coordination with RCCs in areas with dense offshore infrastructure
- Use of updated GMDSS and flight tracking information in decision-making
As a result, crews develop practical familiarity with the amended guidance.
Interaction with External Stakeholders
Shipowners should also consider how the new MoU templates and approval processes may translate into national or regional expectations.
This is particularly important when vessels operate in foreign SAR regions or near offshore installations.
Turning Compliance into Operational Readiness
When managed correctly, the transition to the amended IAMSAR Manual becomes more than a compliance exercise. Instead, it offers an opportunity to strengthen overall emergency preparedness.
A proactive approach may include:
- A targeted gap analysis between existing SMS procedures and the amended IAMSAR guidance
- Structured workshops for DPAs, Masters and senior officers based on realistic SAR scenarios
- Updates to navigational audit checklists to verify practical application of IAMSAR Volume III
- Integration of SAR considerations into voyage planning and risk assessments
This approach supports both regulatory compliance and operational resilience.
