 Life raft servicing is a mandatory requirement under the International Convention for the Safety of Life at Sea (SOLAS) and plays a vital role in ensuring life-saving equipment functions reliably during emergencies. Commercial vessels rely on life rafts as the line of defense when evacuation becomes necessary, making regular inspections and maintenance critical for the safety of crew and passengers.

Routine life raft servicing not only helps shipowners comply with international maritime regulations but also identifies potential defects before they compromise the raft's performance. In this guide, we'll explain the complete life raft servicing procedure, inspection intervals, mandatory tests and best practices to help shipowners, operators and crew maintain compliance and operational readiness.      

What is Life Raft Servicing?

Life raft servicing is the process of inspecting, testing, repairing, and certifying inflatable life rafts at an authorized service station. The objective is to verify that the life raft, its accessories, and its launching equipment remain in optimum condition and are capable of performing as intended during an emergency.

A standard servicing procedure typically includes:

• Visual inspection of the life raft container
• Inflation and pressure testing
• Inspection of the emergency equipment pack
• Examination of buoyancy chambers
• CO2 cylinder inspection and weighing
• Hydrostatic Release Unit (HRU) verification (where applicable)
• Repair of damaged components
• Documentation and certification

Why is Life Raft Servicing Important?

Life rafts are designed to save lives during emergencies such as fire, flooding, collision, grounding, or vessel abandonment. However, prolonged exposure to harsh marine environments can cause deterioration of the raft, its components, and emergency equipment.

Regular servcing helps to:

• Ensure compliance with SOLAS and IMO requirements
• Detect hidden defects before they become critical
• Verify proper inflation and buoyancy
• Extend the service life of the equipment
• Improve crew safety during emergencies
• Reduce the risk of Port State Control deficiencies

SOLAS Requirements for Life Raft Servicing

Adherence to life raft servicing procedures is not merely a matter of compliance with regulations that meet the SOLAS standards and requirements; it's a matter of life and death at sea. Proper servicing ensures that life rafts remain fully functional and reliable, ready to deploy in the most challenging circumstances. To safeguard lives on the open sea, strict adherence to life raft servicing guidelines is paramount.

Life Raft Servicing Procedures: Step-by-Step Checklist

A comprehensive life raft servicing procedure involves several inspection and testing stages.

1. External Container Inspection

The servicing process begins with a thorough inspection of the container.

• Technicians examine:

  • Container condition
  • Corrosion or damage
  • Security of sealing arrangements
  • Container identification markings
  • Hydrostatic Release Unit installation (if fitted) '

Any signs of deterioration are addressed before proceeding.

2. Life Raft Inflation Test

The life raft is carefully inflated under controlled conditions to verify:

• Inflation system performance
• Buoyancy chamber integrity
• Canopy condition
• Boarding arrangements
• Internal fittings
• Structural stability

The raft must inflate completely within the specified time.

3. General Inspection (GI) Tests

A detailed inspection is carried out on all critical components, including:

• Inflation valves
• Pressure relief valves
• Floor construction
• Boarding ladder
• Painter line
• Sea anchor
• Buoyancy tubes
• Internal lighting
• External lights
• Reflective tapes
• Emergency equipment pack

Any worn or damaged components are repaired or replaced.

4. Pressure Retention Test

The inflated life raft is left under pressure for a specified period to verify that no air leakage occurs.
This test confirms:

• Air tight buoyancy chambers
• Valve integrity
• Seam condition
• Overall structure performance

5. Floor Seam Test

The floor seam is inspected to identify:

• Delamination
• Cracks
• Separation
• Material degradation

Maintaining floor integrity ensures occupant comfort, insulation and buoyancy.

6. Emergency Equipment Inspection

Every emergency equipment pack is opened and inspected.
Typical contents include:

• Flares
• Drinking Water
• Food rations
• First aid kit
• Repair kit
• Paddles
• Torch
• Sea sickness tablets
• Sponge
• Floating knife

Expired or damaged items are replaced with approved equipment.

7. CO2 Cylinder Inspection

The inflation cylinder is inspected for:

• Correct weight

• Corrosion

• Valve condition

• Certification validity

• Leakage

The cylinder is replaced or serviced if required.

8. Life Raft Repairs and Container Maintenance

If defects are identified during servicing, approved repair procedures are carried out using manufacturer-approved materials and techniques.

9. Final Certification

Once servicing has been successfully completed, the life raft is repacked, sealed and certified.
Documentation generally includes:

• Service certificate
• Inspection report
• Test results
• Replacement records
• Next service due date

Proper documentation is essential for statutory surveys and PSC inspections.

Common Life Raft Deficiencies Found During Servicing

During inspections, technicians frequently encounter issues such as:

• Damaged containers
• Corroded CO2 cylinders
• Air leakage
• Worn inflation valves
• Expired emergency equipment
• Damaged canopy fabric
• Faulty internal lights
• Missing accessories
• Deteriorated painter lines
• Incorrect packing

Identifying these problems early helps prevent equipment failure during emergencies.

Best Practices for Shipowners and Operators

To maximise safety and regulatory compliance:

• Schedule servicing before the due date.
• Use only manufacturer-approved service stations.
• Maintain complete servicing records.
• Conduct regular onboard visual inspections.
• Replace expired emergency equipment promptly.
• Ensure crew members understand liferaft launching procedures.
• Follow the manufacturer's maintenance recommendations.
