Technical breakdown of SOLAS A & B life-saving appliance packs for lifeboats and liferafts under IMO LSA Code. Rations shelf-life audits, sea anchors, heliograph signal mirrors, thermal protective aids (TPA), and emergency repair kits.
Operating in strict compliance with international maritime safety codes—including
SOLAS Chapter II-1/II-2/III, the IMO Fire Safety Systems (FSS) Code,
LSA Code, IGC Code, and MARPOL Annex I—commercial
vessels require rigorous preventive servicing, statutory inspections, and precision overhaul of mission-critical systems.
Seanav Technical Engineering Board delivers end-to-end class-approved servicing across UAE ports and drydocks,
integrating certified OEM parts, calibrated instrumentation, and comprehensive documentation to ensure seamless Port State Control (PSC)
and Classification Society compliance.

1. SOLAS A and SOLAS B Emergency Survival Craft Equipment
Every lifeboat, rescue boat, and inflatable liferaft on international voyaging vessels must carry a fully compliant emergency equipment pack as stipulated under the IMO International Life-Saving Appliance (LSA) Code (Sections 4.1, 4.4, and 4.5) and SOLAS Chapter III. Cargo vessels engaged on international voyages are typically equipped with SOLAS A Packs, whereas short-voyage or domestic vessels may carry SOLAS B Packs.
The pack contents represent the critical lifeline for crew and passengers during abandoned-ship events, sustaining life for prolonged periods in remote oceanic environments.
2. Mandatory Inventory Breakdown & Maintenance Standards
Survival craft packs incorporate medical, hydration, caloric, navigational, and signalling resources:
- Drinking Water Rations: Vacuum-sealed multi-layer sachet packs providing not less than 1.5 liters per certified person (SOLAS A) or 1.0 liter per person (SOLAS B). Watertight, airtight, and resistant to freezing (-30°C).
- Emergency Food Rations: Compact high-calorie energy bars providing not less than 10,000 kJ (2,400 kcal) per person per SOLAS A specification, balanced in carbohydrates and fats to minimize thirst and metabolic waste.
- First Aid & Medical Supplies: Waterproof first-aid kits meeting WHO/IMO standards containing burn preparations, antiseptics, sterile dressings, anti-seasickness tablets (min. 6 doses per person), and analgesics.
- Survival Tools & Seamanship Hardware: Sea anchor with high-strength hawser line, bailers, sponges, buoyant safety knives, waterproof LED signalling torches with spare batteries, heliograph daylight signal mirrors, whistle, radar reflector, and Thermal Protective Aids (TPA) for at least 10% of craft capacity.
3. Expiry Monitoring & Periodic Servicing Audits
Perishable items within survival craft packs—namely drinking water, emergency food bars, medical dressings, anti-seasickness medication, and alkaline battery packs—possess statutory shelf lives ranging from 3 to 5 years from production. During annual lifeboat surveys and certified liferaft station overhauls, these components are individually audited, verified for vacuum seal integrity, and replaced before expiration.
Statutory & Operating Specification Matrix
| Component | SOLAS LSA Code Standard | Statutory Shelf-Life / Audit Rule |
|---|---|---|
| Emergency Drinking Water | 1.5 L/person (SOLAS A); ISO 18813 | 5 Years max (inspect vacuum integrity annually) |
| Emergency Food Ration Bars | ≥10,000 kJ/person; ISO 18813 | 5 Years max (hermetically foil-wrapped) |
| First Aid Kit | WHO / IMO LSA Code Section 4.4.8 | 3 Years max (controlled pharmaceutical dates) |
| Anti-Seasickness Medication | Min 6 doses/person + 1 seasick bag/person | 3 Years max (batch expiry date audit) |
| Thermal Protective Aid (TPA) | LSA Code Section 2.5 (10% capacity min) | Visual audit of foil pouch and zip closure |
Diagnostic & Failure Resolution Protocols
| Audit Discrepancy | Defect Consequence | Remediation Protocol |
|---|---|---|
| Breached Food Foil Packaging | Humidity absorption, mold formation, rancidity | Discard damaged ration bricks immediately; restock with certified factory-sealed replacement units. |
| Corroded Torch Battery Terminals | Signalling failure during night-time evacuation | Clean terminal springs; supply waterproof LED signalling torches equipped with fresh alkaline batteries. |
| Torn Sea Anchor Drogue Cloth | Survival craft broadside broaching in heavy swells | Replace drogue assembly with IMO-compliant heavy-gauge canvas/nylon sea anchor and swivel shackle. |
