The International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual is the bedrock of global Search and Rescue (SAR) coordination. As maritime activities evolve, driven by technological advancements, new regulations, and the expansion of offshore infrastructure, so too must the procedures guiding our response to emergencies at sea. Image for representation purposes only The 2025 Edition of the IAMSAR Manual, with amendments adopted by the IMO and ICAO, brings crucial operational changes. This isn’t just paperwork; it’s an essential shift that maritime companies, owners, and shipmasters must integrate into their safety systems now. The most important date for compliance is January 1, 2026. SOLAS Regulation V/21 mandates that all ships carry an up-to-date copy of IAMSAR Volume III (Mobile Facilities). To comply, the new 2025 edition must be acquired and placed onboard the vessels (in hard copy format, as stipulated by MSC-MEPC.2/Circ. 2 for emergency use) before this date. Major Operational & Technical Amendments Affecting Vessels The amendments impact all three volumes, but Volume III (Mobile Facilities) contains the crucial operational guidance for shipboard personnel. Here are the key areas requiring immediate attention and training updates- 1. Alignment with the Modernised GMDSS Regulations The amendments to IAMSAR Manual Volume III directly correspond with the 2024 updates to the SOLAS Global Maritime Distress and Safety System (GMDSS) regulations. Impact on Crew: This ensures that SAR communication protocols and distress procedures within IAMSAR are fully consistent with the modernised GMDSS architecture. Crews must be familiar with the updated communication methods, distress relay procedures, and the integration of new technologies, ensuring seamless communication across all stages of a SAR mission. Action Required: Review and update your vessel’s Muster Lists, Emergency Response Checklists, and safety management procedures to reflect the revised GMDSS communication protocols as they appear in the new IAMSAR text. 2. Search and Rescue near Offshore Renewable Energy Installations The increase in the number of offshore wind and renewable energy farms introduces unique hazards and coordination challenges for SAR missions. A new dedicated section in Volume II addresses these structures. Challenges Addressed: The guidance covers navigation hazards, restricted zones, potential radio communication blockages ( from large metal structures), and the need for specific communication protocols with installation operators. Impact on Masters & Bridge Officers: Vessels operating in or transiting near these complexes must be aware of the specific coordination procedures, safe distances, and potential limitations on traditional search patterns in case of an emergency. 3. Enhanced Guidance for Night Search Operations The new edition introduces detailed operational guidance to standardise the use of advanced detection technology, including a new Appendix W (Volume II) for Rescue Coordination Centre (RCC) staff. New Technologies: This guidance focuses on the effective use of Electro-Optic/Infrared (EO/IR) systems and Night Vision Devices (NVDs). EO/IR systems detect thermal signatures (e.g., a person in the water against the cooler ocean), dramatically improving detection capabilities in complete darkness, fog, or smoke. Relevance for Ships: While these systems are primarily for aircraft/dedicated SAR units, the ability of vessels to act as a
