Study Notes

Cargo Handling and Stowage

Essential for safe loading, unloading, and transfer of cargo on ships.
Equipment selection depends on cargo type, vessel type, and operational needs.

Types of Cargo Handling Equipment

Cranes and Derricks
- Used for lifting and moving cargo on various vessel types.
- Safety measures include load distribution, regular maintenance, operator training, and safety zones.
Conveyor Systems
- Operate on bulk carriers for continuous cargo movement (e.g., coal, grain).
- Key components include conveyor belts, idlers, drive pulleys, loaders/unloaders, and elevators.
Pumps (for Liquid Cargo)
- Essential for transferring liquids in tanker vessels.
- Types include centrifugal, axial flow, and positive displacement pumps (screw, gear, eductors, peristaltic).
- Safety measures include proper venting, regular maintenance, and monitoring flow rates to prevent leaks.
Winches and Capstans
- Used for mooring lines and anchoring activities.
- Safety considerations include load limits, regular inspections, crew training, and emergency stop features.
Forklifts and Pallet Jacks
- Primarily used on Ro-Ro vessels for moving palletized cargo.
- Require operator certification, load balance techniques, and regular maintenance.
Cargo Nets and Slings
- Suitable for handling irregular or heavy loads not manageable by standard equipment.
- Safety involves using appropriately rated gear, secure cargo fastening, and regular inspections.
Automated Systems
- Include AGVs and robotic arms for efficient cargo handling in modern terminals.
- Safety considerations entail maintaining emergency shutdown protocols and regular software updates.

General Safety Considerations

Training
- Comprehensive training for crew on cargo operations is crucial for hazard awareness.
Communication
- Essential to coordinate between bridge, cargo teams, and shore personnel during operations.
Emergency Procedures
- Regular drills for fire, spills, and equipment failures enhance preparedness.
Personal Protective Equipment (PPE)
- Mandatory use of PPE (helmets, gloves, safety shoes) during cargo operations.
Securing Cargo
- Proper lashing and securing methods are vital to prevent cargo movement and ensure safety during transit.
