PACKING & DUNNAGE MATERIALS: PROTECTING CARGO DURING HANDLING AND TRANSIT

Reliable Cargo Protection at Sea

Cargo transported by sea is constantly exposed to movement, vibration, humidity, and handling stress. Without proper packing and dunnage materials, even well-planned shipments can suffer serious damage. From bulk commodities to heavy project cargo, protective materials play a vital role in maintaining cargo stability and structural integrity throughout the voyage.

Packing and dunnage are not just supportive materials  they are critical safety components that reduce financial loss, prevent cargo claims, and ensure smooth marine operations.

1. ROLE OF DUNNAGE IN CARGO SAFETY

Stability and Load Distribution

Dunnage refers to materials placed beneath, between, or around cargo to secure and protect it during handling and transit. Proper dunnage prevents shifting, absorbs shock, and distributes weight evenly across the cargo hold.

Key functions of dunnage include:

• Preventing cargo movement caused by vessel rolling and pitching
• Protecting cargo from direct contact with steel surfaces
• Distributing concentrated loads across tank tops
• Reducing vibration impact
• Maintaining proper spacing between cargo units
• Supporting heavy-lift and oversized cargo

Inadequate dunnage can result in structural damage, cargo collapse, contamination, and expensive claims.

2. TYPES OF PACKING MATERIALS USED ONBOARD

Engineered for Marine Conditions

Different cargo types require specific packing materials depending on weight, fragility, and environmental exposure. Marine packing materials must withstand moisture, pressure, and movement during long sea voyages.

Common materials used onboard include:

• Wooden Dunnage (timber blocks, planks, wedges)
• Plywood sheets for surface protection
• Inflatable Dunnage Airbags for gap filling
• Rubber mats for anti-slip protection
• Plastic sheets for moisture barriers
• Corrugated sheets for cushioning
• Foam padding for fragile cargo
• Steel strapping and lashing materials
• Tarpaulins for weather protection

Selecting the correct material ensures maximum cargo protection and regulatory compliance.

3. PREVENTING MOISTURE AND STRUCTURAL DAMAGE

Protecting Cargo from Environmental Risks

Moisture is one of the leading causes of cargo damage at sea. Condensation, commonly known as “cargo sweat,” can damage steel products, machinery, agricultural goods, and packaged materials.

Preventive measures include:

• Using moisture-resistant liners and plastic wrapping
• Installing desiccants inside cargo holds or containers
• Ensuring wooden dunnage is dry and treated
• Elevating cargo above tank tops
• Applying anti-corrosion coatings where required
• Maintaining proper ventilation during transit

Structural damage can also be minimized through proper weight planning, secure lashing, and correct cargo distribution to withstand vessel motion.

4. INSPECTION CONSIDERATIONS FOR CARGO HOLDS

Ensuring Hold Readiness Before Loading

Cargo hold preparation is a critical step before loading operations begin. A poorly prepared hold can compromise even the best packing arrangements.

Important inspection considerations include:

• Checking for moisture, water ingress, or condensation
• Ensuring holds are clean and free from previous cargo residues
• Inspecting tank tops and bulkheads for damage
• Verifying bilge systems are operational
• Checking ventilation systems
• Confirming compliance with charter party requirements

Thorough inspection combined with proper dunnage application significantly reduces cargo risk.
