Safe maritime operations depend heavily on proper cargo securing practices and reliable Life Saving Appliances (LSA). Dunnage, lashing systems, emergency rations, and potable water storage all play essential roles in preventing accidents, ensuring cargo integrity, and safeguarding crew survival during emergencies.
Using certified, SOLAS-approved equipment is not just a best practice it is a regulatory requirement for all seagoing vessels.

1. Dunnage & Packing: The Foundation of Cargo Safety
Dunnage and proper packing form the first layer of protection against cargo movement and damage. They help maintain stability during rough weather, vessel motion, and long voyages.

Types & Applications:
• Wooden Dunnage: Provides cushioning and keeps cargo elevated from moisture
• Airbags & Inflatable Dunnage: Fills voids between cargo units to prevent shifting
• Plastic/Polymer Dunnage: Lightweight, reusable options for specific cargo types

Why It Matters
Correct dunnage distributes load, minimizes impact damage, prevents cargo shifting, and protects both the cargo and the vessel’s structural integrity.

2. Lashing Systems: Rope, Chain, Web & Certified Equipment
Lashing ensures cargo stays firmly secured throughout the voyage. Different materials and equipment suit different load requirements.

Types of Lashing:
• Rope Lashing: Flexible; suitable for light cargo and general securing
• Chain Lashing: High-strength; used for heavy, oversized, or project cargo
• Web Lashing: Polyester webbing; strong with low surface damage risk
• Certified Securing Equipment: Ratchet tensioners, turnbuckles, lashing bars, twist locks

Why It Matters
Using the right lashing prevents sliding, tipping, rolling, and cargo loss. Certified equipment ensures compliance with IMO Cargo Securing Manual (CSM) standards and guarantees tested load capacities.

3. LSA Requirements: Emergency Rations & Potable Water
Every lifeboat and life raft must carry SOLAS-compliant emergency supplies to ensure survival during rescue delays.

Required Supplies:
• Emergency Rations: High-energy food packs, minimum 10,000 kJ per person
• Potable Water: Minimum 3 liters per person, packed in sealed, tamper-proof containers
• Stable Storage: Designed to withstand extreme temperatures and long shelf life

Why It Matters
These supplies can be the difference between life and death during an emergency evacuation. Compliance ensures vessels are fully prepared for unforeseen situations.

4. Certified IMO/SOLAS-Approved Supplies
All securing materials, LSA equipment, emergency rations, and potable water must come from internationally approved manufacturers.

What Certification Ensures:
• Products meet performance and endurance standards
• Materials are tested for marine environments
• Reliability during critical situations
• Full compliance during PSC checks and audits

Why It Matters
Uncertified equipment increases safety risks, leads to non-compliance penalties, and can jeopardize survival or cargo safety in emergencies.

5. Ensuring Safe Cargo Handling & Crew Survival
Reliable cargo protection and preparedness begin with proper securing materials and certified LSA supplies.

Key Best Practices Include:
• Using appropriate dunnage for each cargo type
• Choosing the correct lashing method and certified equipment
• Regular inspection and maintenance of securing gear
• Strict adherence to SOLAS safety supply guidelines
• Verifying all materials are sourced from approved manufacturers

These measures ensure cargo integrity, vessel stability, and readiness for emergency situations on every voyage.

Final Thoughts
Ship safety and cargo protection rely on strong foundations: correct dunnage, proper lashing techniques, and high-quality SOLAS-certified emergency supplies. With the right materials and strict adherence to international standards, vessels can operate safely, minimize risks, and guarantee protection for both cargo and crew throughout the journey.
