What is break-bulk cargo?

Break-bulk cargo, also known as breakbulk or general cargo, refers to goods that are stowed on ships in individually counted units. This method is distinct from cargo loaded into modern intermodal containers or bulk cargo, which is transported unpackaged in large quantities.

How does break-bulk cargo differ from bulk cargo?

Unlike bulk cargo, which is transported unpackaged directly into a ship's holds and measured by volume or weight (like oil or grain), break-bulk cargo consists of goods stowed in individually counted units, often packaged in smaller containers.

What is the origin of the term 'break-bulk'?

The term 'break-bulk' originates from the historical maritime phrase 'breaking bulk,' which referred to the act of commencing the unloading of a ship's cargo or extracting a portion of it from the hold.

What are ships that carry break-bulk cargo commonly called?

Ships that transport break-bulk cargo are frequently referred to as general cargo ships.

How is break-bulk cargo typically handled and stowed on ships?

Break-bulk cargo is handled and stowed piecemeal, often bundled into unit loads for hoisting. These unit loads can be secured using cargo nets, slings, or crates, or items can be stacked on trays, pallets, or skids.

What is the ideal method for loading and unloading break-bulk cargo?

Ideally, break-bulk cargo is lifted directly into and out of a vessel's holds. However, it may also be lifted onto or off the deck using cranes or derricks located on the dock or the ship itself.

What role do stevedores play in handling break-bulk cargo?

Stevedores are responsible for manually handling and competently stowing break-bulk cargo that is lifted onto the ship's deck rather than directly into the hold, including rollable or liftable goods.

What is dunnage used for in the context of break-bulk cargo stowage?

Dunnage is used to secure break-bulk and general freight inside a vessel, providing a protective layer between the cargo and the ship's structure, and ensuring stability.

How has the volume of break-bulk cargo changed since the 1960s?

Since the 1960s, the volume of break-bulk cargo has significantly declined worldwide due to the mass adoption of intermodal containers.

What is a 'break-in-bulk' point?

A break-in-bulk point is a location where goods are transferred from one mode of transportation to another, such as at docks where cargo moves from ships to trucks.

What was the historical significance of break-bulk cargo in shipping?

Break-bulk cargo represented the most common method of shipping for the majority of maritime history before the advent of containerization and specialized bulk carriers.

What are the primary reasons for the decline of break-bulk cargo in favor of containerization?

Containerization makes cargo more homogenous, enabling economies of scale, and is significantly more efficient for loading and unloading, reducing ship turnaround times. It also led to substantial reductions in shipping and loading costs, as well as decreased damage and theft.

How did tankers and bulk carriers contribute to the decline of break-bulk cargo?

The introduction of specialized tankers and bulk carriers reduced the need to transport liquids in barrels and grains in sacks, which were traditional forms of break-bulk cargo. These specialized vessels and their associated shore facilities offered greater efficiency.

What are the advantages of break-bulk shipping in certain contexts, particularly in less developed areas?

Break-bulk shipping retains an advantage in areas where port development has not kept pace with modern shipping technology, as it requires minimal shore facilities like a wharf, dock workers, and warehouses, making it accessible where advanced infrastructure is lacking.

Can break-bulk cargo access ports that larger container ships or bulk carriers cannot?

Yes, break-bulk cargo can be offloaded onto smaller vessels or lighters, enabling transport into ports that larger container ships, tankers, or bulk carriers might be unable to access due to size or water depth limitations.

Describe the typical loading and unloading process for break-bulk cargo.

Cargo is often delivered to the dock in advance and stored in warehouses. When the ship arrives, the cargo is moved to the quay and lifted aboard using the ship's gear or dockside cranes. The discharge process is the reverse of loading, with individual items being handled.

What preparation is done to ship holds before loading break-bulk cargo?

Before loading, any signs of previous cargo are removed, holds are swept, washed if necessary, and any damage is repaired. Dunnage is also prepared and laid out to receive the cargo, providing a protective base.

How is bagged cargo, such as coffee sacks, stowed on a ship?

Bagged cargo is stowed on double dunnage, kept clear of the ship's sides and bulkheads, and protected from pillars and stanchions with matting or waterproof paper to prevent damage and contamination.

What are the requirements for stowing baled goods?

Baled goods are stowed on single dunnage at least 50 mm thick. They must be clean with intact bands, and stained or oily bales are rejected due to the risk of spontaneous combustion. They are also kept clear of new paintwork and covered to prevent damage from dripping sweat.

How are wooden barrels or casks stowed on ships?

Wooden barrels are stowed on their sides on dunnage beds to keep the bilge off the deck, with the bung facing upwards. Wedges called quoins are used to prevent movement, and barrels are typically stowed fore and aft. Subsequent tiers are stowed in the hollows of the tier below, a method known as 'bilge and cantline' stowing.

What are barrels, also known as casks or tuns, primarily used for in shipping?

Barrels, casks, or tuns are primarily used for transporting liquids such as wine, water, brandy, whiskey, and oil. Their spherical shape facilitates rolling and reduces friction when changing direction.

How should corrugated boxes be stowed to ensure safe transport?

Corrugated boxes are stowed on a good layer of dunnage and protected from moisture. They should not be overstowed with anything other than similar boxes. They are often loaded onto pallets to form unit loads, with slings sometimes left on for easier discharge.

What precautions are taken when stowing wooden boxes or crates?

Wooden boxes or crates are stowed on double dunnage in the holds and single dunnage in the 'tween decks. Heavy boxes are placed at the bottom for stability, and loading slings are often left attached to aid in discharge.

How are metal drums typically stowed on board a ship?

Metal drums are stowed on end, with dunnage placed between tiers, within the longitudinal space of the ship to ensure stability and prevent damage.

How are paper reels or rolls handled during stowage on ships?

Paper reels or rolls are generally stowed on their sides, and care is taken to ensure they are not crushed during the loading and stowage process.

How are motor vehicles handled for break-bulk shipping, and how does this differ from Ro-Ro vessels?

On break-bulk ships, motor vehicles are lifted aboard and secured with lashings after preparation, including the removal of hazardous liquids. This differs from roll-on/roll-off (Ro-Ro) vessels, where vehicles are driven on and off under their own power.

How is rolled steel typically stowed on ships?

Rolled steel is stored with its axis oriented in the forward and aft direction of the ship to maintain stability and prevent shifting.

Why are steel girders and other long, heavy items stowed fore and aft on ships?

Long heavy items like steel girders are stowed fore and aft to prevent them from shifting if the ship rolls heavily, which could cause them to pierce the ship's side and lead to severe damage or sinking.

What is a major disadvantage of break-bulk cargo concerning port operations and resource utilization?

A significant disadvantage of break-bulk cargo is that it requires more resources at the wharves at both ends of a ship's journey, including more longshoremen, loading cranes, warehouses, and transport vehicles, often occupying more dock space due to the handling of individual units.

What is the primary advantage of containerization over break-bulk cargo in terms of efficiency and cost?

Containerization significantly increases efficiency by making cargo more homogenous, enabling greater economies of scale, and allowing for faster ship turnaround times in port due to more efficient loading and unloading processes. This also led to substantial reductions in shipping and loading costs.

What impact did containerization have on shipping and loading costs?

Once widely adopted, containerization reduced shipping and loading costs by an estimated 80% to 90%, making it a far more economical method than traditional break-bulk handling.

What specific types of cargo were historically transported using break-bulk methods that are now predominantly handled by specialized vessels?

Historically, liquids were transported in barrels and grains in sacks using break-bulk methods. These types of cargo are now predominantly handled by specialized tankers and bulk carriers, respectively.

What is the main advantage of break-bulk shipping in less developed port areas?

The main advantage of break-bulk shipping in less developed areas is its minimal requirement for shore facilities, needing only a wharf, dock workers, and warehouses, making it accessible where advanced infrastructure for container or bulk handling is lacking.

Can break-bulk cargo be offloaded onto smaller vessels for transport into minimally developed ports?

Yes, break-bulk cargo can be offloaded onto smaller vessels or lighters, which allows for transport into even the most minimally-developed ports that larger container ships, tankers, or bulk carriers might not be able to access.

Provide an example of a modern situation where break-bulk cargo is still used despite advanced shipping technology.

Understanding Breakbulk Cargo

Definition and Distinction

Break-bulk cargo refers to goods that are stowed aboard ships in individually counted units. Traditionally, these items are recorded on distinct bills of lading, categorized by product. This contrasts sharply with modern shipping practices that utilize intermodal containers or bulk cargo, which is loaded directly, unpackaged, and measured by volume or weight (e.g., oil or grain).

The Term's Origin

The term "break-bulk" originates from the maritime phrase "breaking bulk," which signifies the commencement of unloading a ship's cargo or the extraction of a portion thereof. Ships that handle this type of cargo are often referred to as general cargo ships.

Historical Context and Decline

For the majority of shipping history, break-bulk was the predominant method of cargo transport. However, since the widespread adoption of containerization in the late 1960s, the volume of break-bulk cargo has significantly diminished. Containerization offers greater efficiency, reduced costs, and less damage and theft, leading to faster ship turnaround times.

Loading and Unloading Procedures

The Process

Break-bulk cargo is handled piecemeal, often bundled into unit loads using nets, slings, crates, or pallets. The process typically involves storing cargo in warehouses before the ship's arrival. Once the vessel docks, cargo is moved to the quay and lifted aboard using ship's gear (derricks, cranes) or dockside cranes. The discharge process is the reverse.

Labor and Stowage

This method is labor-intensive. Each individual item is lifted separately. Items like bags might be loaded in batches using slings or nets, while cartons can be placed on trays. Once aboard, each item requires careful, separate stowing. Securing the cargo within the vessel involves the use of dunnage. In the absence of hoisting equipment, manual labor, including human chains, was historically employed.

Unit Loads and Packaging

Goods are typically packaged in smaller containers such as bags, boxes, crates, drums, or barrels. Unit loads, where items are secured to pallets or skids, are also common. When such unit loads are used, the lifting slings are often left attached to facilitate easier discharge at the destination.

Common Types of Breakbulk Cargo

Bagged Cargo

Examples include coffee beans or grains packed in sacks. These are stowed on double dunnage, kept clear of ship's sides and bulkheads, and protected from moisture and potential damage from new paintwork or dripping sweat.

Baled Goods

Items like textiles or fibers are transported in bales. They require clean bales with intact bands and are stowed on thick dunnage. Special care is taken to keep them away from potential sources of contamination or spontaneous combustion.

Barrels and Casks

Traditionally used for liquids like wine or oil, wooden barrels are stowed on their sides on dunnage beds, with bungs facing upwards. They are secured with wedges (quoins) and typically stowed fore and aft to prevent shifting. Their rounded shape facilitates rolling.

Boxes and Crates

Corrugated boxes and wooden crates are stowed on dunnage, protected from moisture. Military-grade or weather-resistant packaging is available. Heavy items are given bottom stowage, and loading slings are often retained for easier discharge.

Drums

Metal drums, often containing chemicals or oils, are stowed upright on end, with dunnage between tiers, typically aligned longitudinally within the ship's holds.

Paper Reels

Large rolls of paper are generally stowed on their sides. Measures are taken to prevent crushing, and they are secured to avoid movement during transit.

Motor Vehicles

Automobiles are carefully lifted aboard and secured with lashings to prevent damage. Hazardous liquids are removed prior to transport, distinguishing this method from roll-on/roll-off (Ro-Ro) shipping where vehicles are driven aboard.

Rolled Steel & Girders

Items like rolled steel coils and steel girders are long and heavy. They are stowed fore and aft to prevent shifting, which could cause significant damage, such as piercing the ship's hull, if stowed athwartships during heavy rolling.

Advantages of Breakbulk

Accessibility for Developing Ports

Break-bulk shipping requires relatively minimal shore facilities compared to containerized or specialized bulk transport. This makes it advantageous in regions where port infrastructure development has not kept pace with modern shipping technologies. Goods can be offloaded onto smaller vessels or lighters, allowing access to ports inaccessible to larger ships.

Specialized Handling Needs

Certain goods, like fuel oil delivered in barrels to remote islands (e.g., Tuvalu), necessitate break-bulk methods even if the port can handle larger vessels, due to specific logistical requirements or infrastructure limitations.

Disadvantages of Breakbulk

Resource Intensity and Time

The primary disadvantage is the labor-intensive nature of loading and unloading, requiring more resources at wharves, including dockworkers, cranes, warehouses, and transport vehicles. This often leads to longer port stays and increased dock space utilization.

Cost and Efficiency

Compared to containerization, break-bulk operations are generally less efficient and more costly due to the manual handling and individual item management. While containerization reduced costs by 80-90%, break-bulk operations are more susceptible to delays, damage, and theft.

Infrastructure Demands

While requiring less infrastructure than container terminals, break-bulk still necessitates adequate wharfage, warehousing, and handling equipment. The transition from break-bulk to specialized ships (like tankers and bulk carriers) and containerization reflects a global trend towards greater economies of scale and efficiency.
