Search and Rescue (SAR) Cooperation Plans Under SOLAS V/7.3 and IMO MSC.1/Circ.1079/Rev.1
Understanding SAR Cooperation Plan requirements, emergency information and practical Search and Rescue coordination for passenger and commercial vessels.
What Is a Search and Rescue (SAR) Cooperation Plan?
Search and Rescue (SAR) operations depend on rapid communication, accurate vessel information and effective coordination between a ship in distress and the appropriate Search and Rescue authorities.
A SAR Cooperation Plan provides a structured means of ensuring that important vessel-specific information is available to support cooperation between the ship, the company and relevant Search and Rescue services during an emergency.
For passenger vessels, RO-RO vessels and other ships carrying substantial numbers of persons, accurate emergency information can be particularly important because the potential consequences of an incident may involve the evacuation or rescue of many people.
SOLAS Chapter V Regulation 7.3
SOLAS Chapter V addresses Safety of Navigation. Regulation 7 concerns Search and Rescue services and requires ships to carry appropriate information concerning Search and Rescue services.
The regulatory framework recognizes the importance of cooperation between ships and the Search and Rescue organization when assistance is required.
The practical implementation of SAR information and cooperation arrangements should therefore be considered together with the vessel's operating profile, communication arrangements, emergency procedures and applicable flag State requirements.
IMO MSC.1/Circ.1079/Rev.1
IMO MSC.1/Circ.1079/Rev.1 is associated with the development and use of Search and Rescue Cooperation Plans. Its purpose is to support effective cooperation between ships and Search and Rescue services.
The underlying concept is straightforward: SAR authorities should be able to obtain useful information about the vessel and its operational circumstances so that appropriate assistance and coordination can be arranged when necessary.
A well-structured plan should therefore be practical, vessel-specific and maintained so that important information remains current.
What Information Should Be Considered in a SAR Cooperation Plan?
The exact information applicable to a vessel depends on its type, operation, flag requirements and trading area. However, a technical review should consider whether the relevant categories of information are properly identified and maintained.
Vessel Identification
Accurate vessel identification and principal particulars should be available so that SAR authorities can quickly establish the identity and characteristics of the vessel requiring or providing assistance.
Vessel Characteristics
Principal dimensions, vessel type, passenger-carrying capability, vehicle capacity and other relevant characteristics may form part of the emergency information required for SAR coordination.
Communication Information
Relevant maritime communication information should be identified so that contact between the vessel and the appropriate SAR authorities can be established and maintained.
SAR Authorities
Applicable Rescue Coordination Centre and relevant SAR contact information should be considered according to the vessel's operating area and established arrangements.
Emergency Information
Information that may assist SAR personnel in understanding the vessel's situation and potential assistance requirements should be appropriately identified.
Document Control
SAR information should be reviewed and updated when vessel particulars, communication arrangements, operating areas or relevant emergency information change.
SAR Planning for RO-RO Passenger Vessels
RO-RO passenger vessels require particular attention to emergency information because they can combine passenger transportation with significant vehicle-carrying operations.
As an example, a project reviewed by PAMS involved a RO-RO passenger vessel with a length overall of 78.92 m and a beam of 14.94 m. The vessel has a carrying capacity of 512 passengers and a vehicle deck designed to accommodate 24 trucks or buses.
These characteristics demonstrate why vessel-specific information is important when preparing emergency and SAR documentation. The information available to SAR authorities should accurately reflect the vessel's actual operational configuration.
SAR Cooperation Plan Technical Review
Vessel Particulars Verification
Confirm that vessel identification, dimensions and other principal particulars contained within the SAR documentation correspond with current vessel information.
Passenger Information
Review the passenger-carrying characteristics relevant to the vessel and emergency response requirements.
Communication Arrangements
Review the information necessary to support emergency communication between the vessel and relevant SAR services.
SAR Contact Information
Review applicable SAR authority and Rescue Coordination Centre information against the vessel's operational arrangements.
Emergency Coordination
Assess whether the information is presented in a way that can support effective coordination during an emergency.
Document Currency
Identify information that may require updating following changes to vessel particulars, operation or communication arrangements.
Common SAR Cooperation Plan Weaknesses
From a technical documentation perspective, the effectiveness of a SAR Cooperation Plan can be reduced when information is incomplete, inconsistent or outdated.
Outdated Vessel Particulars
Changes to vessel configuration, dimensions, passenger capacity or operational characteristics may not always be reflected promptly in emergency documentation.
Incorrect Contact Information
SAR coordination information should be reviewed periodically to ensure that applicable emergency contact details remain appropriate.
Poor Document Accessibility
Important emergency information becomes less useful if crew or emergency-response personnel cannot locate it quickly.
Inconsistent Documentation
Differences between SAR information, vessel particulars, emergency plans and communication records can create unnecessary uncertainty during an emergency.
SAR Cooperation Plan Review Matrix
| Review Area | Technical Question | Objective |
|---|---|---|
| Vessel Identity | Is the vessel correctly identified? | Support rapid vessel identification by SAR authorities. |
| Vessel Particulars | Are principal dimensions and characteristics current? | Provide accurate vessel information for emergency coordination. |
| Passenger Capacity | Is relevant passenger information properly reflected? | Support assessment of potential persons requiring assistance. |
| Vehicle Operations | Are relevant RO-RO vehicle arrangements identified? | Provide SAR authorities with appropriate operational context. |
| Communications | Are relevant emergency communication arrangements identified? | Support effective communication with SAR services. |
| SAR Coordination | Is applicable SAR authority information available? | Facilitate emergency coordination. |
| Document Control | Is the information periodically reviewed? | Maintain current and reliable SAR information. |
Relationship Between SAR Plans and GMDSS
Search and Rescue cooperation and maritime distress communications are closely connected. The Global Maritime Distress and Safety System (GMDSS) provides the communications framework used to support distress alerting, safety communications and coordination.
A SAR Cooperation Plan does not replace the vessel's GMDSS equipment, certificates, operating procedures or required emergency communications. Instead, SAR documentation should be considered as part of the wider emergency-response and communication framework.
SAR Cooperation Plan – Technical Review Process
Collect Current Vessel Information
Establish the current vessel particulars, operating profile and available emergency documentation.
Review Regulatory Framework
Identify the applicable SOLAS, IMO, flag State and operational requirements relevant to the SAR arrangements.
Cross-Check SAR Information
Compare SAR documentation against current vessel and emergency information.
Identify Gaps
Identify incomplete, inconsistent, outdated or unclear information requiring attention.
Technical Recommendations
Provide practical recommendations for improving the accuracy and usability of the SAR Cooperation Plan.
Why Periodic SAR Plan Review Matters
SAR documentation can become outdated even when the vessel itself remains fully operational. Changes in vessel particulars, ownership, management, communication arrangements, operating areas or emergency contacts can affect the accuracy of the information contained within the plan.
Periodic review therefore forms an important part of maintaining the practical effectiveness of emergency documentation.
