Ship Cargo Handling

Ship Cargo Handling

Loading of bulk cargo can be by a variety of methods, ranging from modern sophisticated facilities capable of loading through conveyor belts, chutes, or spouts, at rates of thousands of tonnes per day: whilst in a few backward areas, it may still be necessary to load by the labor intensive system of slitting bags and emptying the contents over the side of hatch coamings into the holds beneath.

Discharging of cargo can be effected by similarly varied methods, free-flowing cargoes such as grains lending themselves to fast, sucker discharge where available, or in extreme cases, bagging in in holds, filled bags then being raised and lifted ashore by slings secured to ship or shore gear.

Much research has taken place in recent years into methods of fast, efficient bulk cargo discharge, operated in many cases from alongside the ship, but sometimes by means of self-discharging equipment built into the carrying vessel.

Much bulk cargo discharging however, is accomplished by grabs fitted to either ship or to shore cranes or derricks, and often charterers and/or receivers will require an entry in the shipping contract to the effect that the ship is suitable for grab discharge. Such a clause can be quite extensive, an example drawn up for a tween-deck vessel reading:

“Vessel to be guaranteed suitable for grab discharge and the cargo to be loaded in lower holds only. No cargo to be loaded in tween-decks, deep-tanks or other places not accessible to grabs. If in loading and/or discharging any extra expenses incurred for cargo not accessible to grabs, Owners to be responsible for all extra expenses and time not to count. Wooden-ceilings to be in proper condition’ for grabs and trimming machines. Deep-tanks, tunnels and all other projections within vessel’s holds are to be sheltered against grab-discharge damage, failing which Owners to be responsible for all consequences, but grabs to be operated in a serviceable fashion. Vessels to have cargo battens, tween-deck hatch-covers and hatch beams removed, and holds to be cleared of all timber, hatch covers, hatch beams etc. If such materials stored in holds, same to be stowed away with due regard to discharging by grabs and trimming by apparatus. Any extra expenses due to failure to comply with this stipulation and time lost thereby to be for Owners’ account”.

Some general cargo and short sea ships have tank tops protected by wooden sheathing. particularly over double bottom bunker tanks, above shaft tunnels and directly beneath hatch openings, and this protection is itself liable to damage when discharging cargo by grab.

As a bulk-cargo discharging operation nears completion, it may well be that bulldozers are placed in cargo holds to shift remaining cargo to piles and locations for grabs to collect and lift. These bulldozers will move in a variety of ways, ranging from rubber-tire to steel caterpillar tracks, and most owners being naturally anxious to avoid possible damage to the tank tops of their ships, will thus specify in charterparties that where possible, only rubber-tire bulldozers may be utilised.

  8. Record cargo details and documentation: Accurate records of the cargo unloaded, including its weight, condition, and any discrepancies or damages, should be maintained. This documentation is essential for settling claims, calculating freight payments, and ensuring compliance with customs and regulatory requirements.
  9. Prepare for departure: Once the unloading process is complete, the cargo holds should be secured, and the vessel should be prepared for departure. This may involve coordinating with the port authorities, agents, and pilots to obtain clearance and ensure a safe departure from the port.

Unloading bulk cargoes requires careful planning, coordination, and execution to ensure safe and efficient operations. By following these steps and adhering to the relevant safety and environmental guidelines, the unloading of bulk cargoes can be carried out smoothly and successfully.

 

Stevedores and Ship Cargo Handling

Stevedores play a crucial role in ship cargo handling, as they are responsible for the safe and efficient loading and unloading of cargo on and off vessels. Stevedores, sometimes referred to as longshoremen or dockworkers, work at ports and terminals and are specialized in handling various types of cargo, including bulk, containerized, and breakbulk.

Key aspects of the role of stevedores in ship cargo handling include:

  1. Loading and unloading operations: Stevedores are responsible for physically loading and unloading cargo from the ship’s holds or deck using specialized equipment such as cranes, forklifts, grabs, and conveyor belts. They must ensure that these operations are carried out safely and efficiently, following the vessel’s loading or unloading plan.
  2. Stowing and securing cargo: In addition to loading and unloading, stevedores are responsible for properly stowing and securing the cargo within the ship’s holds or on the deck. This is particularly important for maintaining the vessel’s stability, preventing cargo damage, and ensuring the safety of the ship and its crew during transit.
  3. Coordination and communication: Stevedores must coordinate and communicate with various parties, such as the ship’s crew, port authorities, terminal operators, and freight forwarders, to ensure smooth cargo handling operations. This may involve sharing information about the cargo, the vessel’s loading or unloading plan, and any special handling requirements or safety concerns.
  4. Safety and environmental compliance: Stevedores must adhere to safety regulations and guidelines to minimize the risk of accidents and injuries during cargo handling operations. They should also follow environmental regulations and best practices to minimize pollution, dust emissions, and other environmental impacts associated with cargo handling.
  5. Cargo documentation: Stevedores are often involved in maintaining records of the cargo loaded or unloaded, including details about the cargo’s weight, condition, and any discrepancies or damages. This documentation is essential for settling claims, calculating freight payments, and ensuring compliance with customs and regulatory requirements.
  6. Equipment maintenance and operation: Stevedores are responsible for operating and maintaining the cargo handling equipment used at ports and terminals. This may include cranes, forklifts, grabs, and conveyor belts. Proper maintenance and operation of this equipment are essential for ensuring the safety and efficiency of cargo handling operations.

Stevedores play a vital role in ship cargo handling, as they are responsible for the safe and efficient loading and unloading of cargo on and off vessels. They must coordinate and communicate with various parties, adhere to safety and environmental regulations, and maintain and operate cargo handling equipment to ensure smooth cargo handling operations at ports and terminals.

 

Why are Dock Workers called Stevedores?

The term “stevedore” is derived from the Spanish word “estibador,” which means “one who loads.” Stevedores are workers who are responsible for loading and unloading cargo from ships in ports and docks. The term “stevedore” has been in use since the mid-1700s and has become the common name for dock workers in many parts of the world.

Originally, stevedores were individuals who worked as independent contractors, hiring themselves out to ship owners or cargo handlers. They were responsible for organizing the loading and unloading of cargo and ensuring that it was handled safely and efficiently. As the shipping industry grew, stevedores became more organized, and labor unions were formed to protect their rights and negotiate better wages and working conditions.

Today, stevedores are typically employed by shipping companies or terminal operators and are responsible for a wide range of tasks, including loading and unloading cargo, operating machinery, and maintaining the dock and equipment. Despite changes in the industry, the term “stevedore” has remained in use as a way of identifying those workers who are responsible for the movement of cargo in ports and docks around the world.

 

What is the difference between a Longshoreman and a Stevedore?

While the terms “longshoreman” and “stevedore” are often used interchangeably, there is a subtle difference between them.

A longshoreman is a worker who is employed to load and unload cargo from ships in a port or harbor. Their work is primarily manual labor, and they use equipment such as cranes, forklifts, and conveyors to move cargo to and from the ship.

A stevedore, on the other hand, is a contractor or company that provides loading and unloading services for ships. They may hire longshoremen or other workers to do the actual physical labor, but their responsibilities extend beyond just the physical movement of cargo. Stevedores are also responsible for coordinating and planning the loading and unloading of cargo, ensuring that the proper equipment and personnel are available, and ensuring that the work is completed safely and efficiently.

In summary, a longshoreman is a worker who performs the physical labor of loading and unloading cargo, while a stevedore is a company or contractor that provides the overall loading and unloading service and is responsible for coordinating and managing the process.
