How To Understand SOLAS Requirements for Rescue Boats

How To Understanding SOLAS Requirements for Rescue Boats

SOLAS (International Convention for the Safety of Life at Sea) is a mandatory safety convention in the maritime sector. As critical lifesaving appliances, rescue boats must comply with SOLAS regulations regarding their design, manufacture, inspection, and operation and maintenance. Here is an overview of the key SOLAS requirements for rescue boats.

1. Defining the scope of SOLAS rescue boats

SOLAS Chapter III specifies the scope of application for rescue boats: ships engaged on international voyages must be equipped with certified rescue boats designed for search and rescue operations at sea and the recovery of persons in the water, while also serving the function of short-range personnel transfer.

> Distinction: Rescue boats are not lifeboats.

Rescue boats focus on rapid search and rescue; lifeboats are designed for prolonged self-sustained survival following ship abandonment.

Fast Rescue Boats (FRBs) constitute a specialized category of rescue boats subject to additional SOLAS provisions.

2. How to meet SOLAS design & construction requirements

- Hull: Possesses sufficient buoyancy and resistance to capsizing; self-righting rescue boats can automatically return to an upright position after capsizing.

- Propulsion: Independent marine engine capable of reliable starting in adverse sea conditions; fuel reserves sufficient for continuous operation.

- Personnel Capacity: Rated passenger capacity, internal space, handrails, and securing points strictly comply with SOLAS standards.

- Materials: Corrosion-resistant and capable of withstanding seawater impact; suitable for long-term marine use.

3. Compliance with launching and recovery system regulations

For rescue boats paired with davits or launching appliances, SOLAS mandates specific requirements for the launching and recovery systems:

- Safe launching and recovery must be possible even when the vessel is trimmed or listed;

- The release mechanism must include a safety lock to prevent accidental disengagement;

- The operating procedure must be simple, enabling the crew to rapidly deploy the boat.

4. Meeting SOLAS equipment requirements

The boat must be equipped with the standard accessories listed under SOLAS regulations—such as lifelines, signaling devices, bilge pumps, first-aid kits, communication equipment, and anchoring gear; the absence of any single item will result in failure to pass the vessel inspection.

5. Inspection, maintenance, and certification

- Factory stage: Must hold a classification society certificate, with the product prototype having successfully completed type testing;

- Onboard stage: Subject to regular weekly, monthly, and annual inspections, with maintenance records retained;

- Decommissioning: Must be replaced upon reaching the end of its service life or if structural damage exceeds permissible limits.

6. Key specifications of Fast Rescue Boats (FRB)

In addition to the general requirements for rescue boats, SOLAS imposes extra requirements for Fast Rescue Boats: higher speeds and superior seakeeping capabilities. Designed for rapid rescue operations in high-risk waters, they are commonly deployed on passenger ships and large cargo vessels.
