What is dry bulk cargo?
Maritime Cargo maybe classified into three (3) categories:
- Bulk Cargo (Dry Bulk Cargo and Liquid Bulk Cargo)
- General Cargo
- Specialized Cargo
Bulk Cargo maybe classified further into liquid bulk cargo (such as crude oil, molasses, chemicals, vegetable oil, etc.), which is transferred in tanker vessels, and dry bulk cargo (such as iron ore, grain, scrap metal, coal/coke, cement, sugar, and fertilizers), which are transferred in dry bulk vessels.
Crude oil is carried in large consignments over long hauls in a relatively small number of routes. Specialized ports and terminals (such as jetties, single buoy, or single point moorings) are used to service the very large tankers. Oil products are carried in smaller shipments to numerous consignees and over many ports.
Grain is carried in dry bulk carriers and occurs in small to medium-size consignments. Handling rates vary and there are several major export and import ports. Vessel range from small to medium size. Ores and coal are carried in large consignments and hence in bigger vessels and over long hauls. The cargo is handled at moderately fast handling rates. There are specialized terminals for handling such types of cargo.
General Cargo is subdivided into break bulk cargo (such as sacks, cartons, crates, drums, pallets, and bags) and is transferred in general cargo ships, neo-bulk cargoes (such as lumber, paper, steel, and autos), and containerized cargoes (such as containers, Lo/Lo, and Ro/ Ro), which are transferred in containerships. General cargo is carried in small consignments to numerous consignees. It originates from numerous ports and production areas and is carried across a multitude of routes to arrive at varied destinations. The nature of the cargo means that handling rates are very slow. General cargo has been unitized with the advent of containerization. Cargo handling has improved markedly, and the cost of handling and transportation has decreased significantly. Progressively bigger containerships are being developed to carry unitized general cargo.
The quantity of cargo that is transported by ship is measured in metric tons (the term tons may be used interchangeably in this book) whereas the maximum that can be placed in a ship is measured by the ship’s deadweight which is a measure of how much cargo can be placed in a ship’s holds for safe carriage.
What is Dry Bulk Cargo?
Dry Bulk Cargo refers to solid commodities that are transported in large quantities without any packaging, often loaded directly into a ship’s hold. These cargoes are typically shipped in bulk carriers, vessels specifically designed to transport dry, unpackaged bulk materials.
Here are some characteristics and examples of dry bulk cargo:
- Unpackaged: Dry bulk cargo doesn’t come in containers or any other type of packaging. It’s usually poured or dumped directly into the cargo holds of ships.
- Solid: Dry bulk cargoes are solid materials, as opposed to liquid or gas.
- Major Bulks: These are the main dry bulk commodities by volume.
- Grains: Such as wheat, rice, corn, and barley.
- Coal: Used in power generation and steel production.
- Iron Ore: Used in steel production.
- Bauxite/Alumina: Used in aluminum production.
- Minor Bulks: These have smaller volumes compared to major bulks but are still significant.
- Agribulks: Such as sugar, soybeans, and fertilizers.
- Cement: For construction.
- Metal concentrates: Such as copper, zinc, or lead concentrates.
- Steel products: Coils, rods, or slabs.
- Forest products: Wood chips, logs, or pulp.
- Major Bulks: These are the main dry bulk commodities by volume.
- Specialized Vessels: Dry bulk cargo is typically transported using bulk carriers. These vessels are specifically designed to transport such cargo efficiently. They range in size from small Handysize to very large Capesize ships.
- Loose Handling: Loading and unloading of dry bulk cargo often require special equipment such as grab cranes, conveyor belts, or bucket systems, since the material is loose and not in containers.
The transportation of dry bulk cargo is an essential part of global trade, especially for raw materials used in production and energy generation. The demand for and transportation of these commodities can be a significant economic indicator.
Infrastructure and Ports: One key aspect of transporting dry bulk cargo is the infrastructure that supports it. Dedicated ports and terminals around the world are designed specifically to handle large volumes of such cargo. These specialized ports are equipped with the machinery and facilities needed to facilitate efficient loading, unloading, and storage.
- Storage Facilities: Depending on the commodity, some dry bulk cargoes may need storage facilities. Silos for grains, open yards for coal, and covered sheds for sugar or fertilizers are common examples.
- Economies of Scale: To make transportation more cost-effective, larger vessels, such as Panamax or Capesize ships, are often used. These vessels, however, require deeper draft ports and larger unloading facilities. As such, not all ports can accommodate them, leading to a concentration of major dry bulk activities in specific ports around the world.
Environmental and Safety Concerns:
- Dust and Pollution: The handling of dry bulk cargoes, especially coal and other minerals, can lead to dust generation. This has environmental implications and can affect air quality. Many modern ports employ dust suppression methods to mitigate this.
- Liquefaction: Some dry bulk cargoes, like nickel ore, have the potential to liquefy if they contain too much moisture. This can drastically affect a ship’s stability and has been the cause of several maritime accidents.
- Spillage: Given the unpackaged nature of these cargoes, there’s a potential for spillage during loading or unloading. This can have environmental repercussions, especially if the spilled cargo can contaminate local waterways or ecosystems.
The dry bulk shipping industry is closely watched by economists and traders alike, as it’s a strong indicator of global economic health. The Baltic Dry Index (BDI) is one such metric that reflects the cost of transporting major raw materials by sea. Changes in the BDI can signal changes in supply and demand for raw materials, which in turn can provide insights into overall global economic conditions.
In conclusion, while dry bulk cargo transportation might seem straightforward, it’s a complex industry with significant implications for global trade, the environment, and economic forecasting. As the world evolves and industries grow, the demand for raw materials and hence the transportation of dry bulk cargoes will continue to play a pivotal role in global commerce.

What are the hazards associated with dry bulk cargoes?
Dry bulk cargoes are granulated, powdered, or similarly sized cargo that is shipped without any specific packaging, other than the ship’s own compartments or holds. While they are important in international trade, there are numerous hazards associated with transporting these types of cargoes. Here’s a list of the main hazards:
- Liquefaction: Some dry bulk cargoes, especially those with a certain moisture content, can undergo a process called liquefaction. When subjected to compaction and vibration during a voyage, these cargoes can transform from a solid state to a viscous, liquid-like state, causing a ship to lose stability and potentially capsize.
- Spontaneous Combustion: Some dry bulk cargoes, such as coal, can self-heat and potentially lead to fires in the cargo holds. This self-heating can be due to chemical reactions within the cargo or microbial activities.
- Oxygen Depletion: Organic materials, like grains or coal, can consume oxygen as they break down, leading to oxygen-depleted environments in cargo holds. This poses a significant risk for anyone entering these spaces.
- Release of Toxic Gases: Decomposition of some cargoes can produce hazardous gases. For instance, coal can release methane, which is flammable, while some agricultural products might release toxic fumigants or phosphine gas.
- Dust Explosions: Cargoes in powdered form can generate dust. If this dust is suspended in the air in the right concentration, it can be highly explosive when exposed to an ignition source.
- Cargo Shift: Improperly stowed cargo can shift during a voyage, particularly in rough seas, causing the vessel to list or become unstable.
- Corrosion: Some dry bulk cargoes can be corrosive to the ship’s structure, especially if they come into contact with moisture.

- Degradation of Cargo: Some cargoes, especially those sensitive to moisture, can degrade during transport if not properly protected. This can lead to financial losses.
- Environmental Impact: Accidental release of some dry bulk cargoes can cause environmental harm, especially if they contaminate the marine environment.
- Overloading: There’s a risk of overloading vessels with bulk cargoes, leading to structural stresses and potential ship failures.
It’s crucial for ship operators, crews, and those involved in loading and unloading dry bulk cargoes to be aware of these hazards. Proper precautions, including cargo inspections, regular monitoring during the voyage, and following established safety protocols, can mitigate many of these risks.
How is dry bulk cargo unloaded?
Unloading (or discharging) dry bulk cargo from ships is a crucial process that needs to be carried out efficiently and safely. Various methods and equipment are used to unload dry bulk cargo, depending on the type of cargo, the size of the ship, and the infrastructure of the port or terminal. Here are the primary methods and equipment used:
- Grab Cranes: These are the most common unloading tools for bulk carriers.
- A large crane equipped with a grab bucket is used.
- The crane reaches into the ship’s hold, the grab descends and takes a large bite of the cargo, then it lifts it out and transfers it to a hopper, truck, conveyor belt, or another storage facility.
- It’s particularly useful for coarse bulk cargoes like coal, ores, and grains.
- Continuous Ship Unloaders (CSU):
- These are large and highly efficient mechanical systems designed to continuously scoop up cargo from a ship’s hold.
- The system generally uses a large boom with a conveyor system or a suction device.
- It can be used for a variety of bulk cargoes, including coal, grains, and phosphate.
- Pneumatic Ship Unloaders:
- These use vacuum technology to suck cargo from the ship’s hold.
- It’s most suitable for fine-grained bulk cargoes like alumina or flour.
- The cargo gets sucked into a receiving hopper and then transferred to a storage facility.
- Self-discharging Ships:
- Some specialized bulk carriers are equipped with their own onboard unloading systems, usually conveyor belts.
- These ships can discharge their cargo without relying on port facilities, making them useful for ports without dedicated unloading infrastructure.
- Used primarily for cargo that comes in rail-mounted containers or wagons.
- The tippler grabs the wagon and turns it upside down, allowing the cargo to fall out.
- Front-end Loaders:
- In some smaller ports or for specific cargoes, traditional front-end loaders can be used to scoop out cargo from the ship’s hold and then transfer it to trucks or hoppers.
- Conveyor Systems:
- After initial unloading using grabs or other means, conveyor systems help move the bulk cargo to storage or further processing areas.
- These are often belt conveyors that can be moved around as needed.
- Dust Suppression Systems:
- While not strictly unloading equipment, it’s worth noting that many dry bulk terminals use dust suppression systems.
- These systems reduce the spread of dust during unloading, which is particularly essential for cargoes like coal or grain to ensure environmental compliance and safety.
It’s important to note that the efficiency of unloading depends on the coordination between the ship’s crew and the terminal operators. Safety measures, such as ensuring no one enters the cargo hold during unloading and monitoring for the release of toxic or flammable gases, must be adhered to throughout the unloading process.
What is the difference between dry bulk carrier and tanker?
Dry bulk carriers and tankers are both types of merchant ships, but they serve different purposes and have distinct designs suited to their specific cargo types. Here’s a breakdown of their differences:
- Type of Cargo:
- Dry Bulk Carrier: This type of ship is designed to transport unpackaged bulk cargo, such as grains, coal, ore, cement, and other dry commodities.

- Tanker: Tankers often need to maintain specific temperatures or conditions inside their tanks. After offloading, they might undergo tank cleaning processes, especially when they’re changing the type of liquid they’re transporting. This ensures that there’s no contamination between cargoes.
- Regulations and Standards:
- Dry Bulk Carrier: They are subjected to regulations regarding the safe carriage of bulk cargo under the International Maritime Solid Bulk Cargoes Code (IMSBC Code).
- Tanker: The transport of oil and chemicals is highly regulated due to the environmental risks involved. The International Convention for the Prevention of Pollution from Ships (MARPOL) sets strict standards, especially Annex I which relates to oil pollution. Tankers might also adhere to regulations set by the International Bulk Chemical Code (IBC Code) when carrying hazardous chemicals.
- Economic Lifespan and Scrapping:
- Dry Bulk Carrier: Dry bulk carriers typically have a longer operational lifespan, which can range between 20-30 years depending on maintenance, market conditions, and regulatory requirements.
- Tanker: While tankers can also operate for many years, stricter regulations, especially regarding environmental safety, can lead to older tankers being scrapped and replaced with newer models that adhere to modern standards.
- Charter Types:
- Dry Bulk Carrier: These ships might operate on voyage charters (where they’re hired for a single journey), time charters (hired for a specific period), or on the spot market.
- Tanker: Similar to dry bulk carriers, tankers can be chartered for single voyages (spot market) or for extended periods (time charter). Additionally, some large oil companies have their own fleet of tankers.
The world of shipping is vast and intricate. Both dry bulk carriers and tankers play critical roles in the global economy, ensuring the movement of essential commodities around the world. They each come with their own sets of challenges, operational nuances, and market dynamics.
While both dry bulk carriers and tankers are essential for global trade, they cater to different types of cargo and have designs optimized for their specific tasks.
What are bulk carriers also known as?
Bulk carriers are often simply referred to as “bulkers.” They are merchant ships specifically designed to transport unpackaged bulk cargo, such as grains, coal, ore, and cement, among others. The term “bulker” is a colloquial shorthand that distinguishes these ships from other types of cargo ships like tankers or container ships.
What is Bulker in shipping?
In shipping, a “bulker” refers to a bulk carrier, which is a type of merchant ship specially designed to transport unpackaged bulk cargo. Here’s a more detailed look at bulkers:
Bulker (Bulk Carrier):
- Purpose: The primary purpose of a bulker is to move large quantities of cargo in bulk form. This can include a wide range of commodities like grains (wheat, corn, barley), minerals (coal, iron ore, bauxite), and other goods like cement, fertilizers, and salt.
- Design: A bulker typically has a large, flat deck and several massive cargo holds below deck. These holds are large, open spaces that can be filled with bulk cargo. The ship’s design often allows for easy loading and unloading, usually through large hatches on the deck that provide access to the holds.
- Types by Size: Bulk carriers come in various sizes, from smaller ships that can access limited ports to gigantic vessels that require deep-water terminals. These types include:
- Handysize Bulk Carrier
- Handymax Bulk Carrier
- Supramax Bulk Carrier
- Ultramax Bulk Carrier
- Panamax Bulk Carrier (named because they’re the maximum size that can fit through the Panama Canal)
- Capesize Bulk Carrier (typically too large for the Panama Canal, so they go around the Cape of Good Hope or Cape Horn)
- Very Large Bulk Carrier and Ultra Large Bulk Carrier
- More Detailed Bulk Carrier Ship Sizes: We kindly suggest that you visit the web page of HandyBulk to learn more about Bulk Carrier Ship Sizes www.handybulk.com
- Loading and Unloading: The cargo can be loaded using conveyor belts, grabs, or chutes, and it can be unloaded using grabs, conveyor systems, or sometimes even by tipping the ship to pour out cargo, especially for ships like self-unloading bulkers.
- Operational Considerations: One of the concerns for bulkers is ensuring even distribution of cargo to avoid issues with the ship’s balance. Another consideration is ensuring that certain cargoes, like grains, don’t spoil during transportation, or that certain ores don’t become unstable and shift suddenly.

In essence, a bulker in shipping refers to a ship that’s tailored for the transport of large quantities of unpackaged bulk goods, making them indispensable for the movement of many primary materials and foodstuffs across the world’s oceans.
Which type of ship has highest salary?
The salary in the shipping industry doesn’t necessarily depend solely on the type of ship but rather on the rank or position aboard the vessel, the company, experience, nationality, and the trade route. However, certain ship types do tend to offer higher salaries due to the specialized nature of their operations and the associated risks.
Here are some types of ships where crew members, especially senior officers, might earn higher salaries:
- LNG (Liquefied Natural Gas) Carriers: Operating these ships requires specialized training because of the technicalities and risks associated with transporting natural gas in its liquefied form. Engineers and captains on LNG carriers are among the highest-paid seafarers.
- Drill Ships and Oil Rigs: Though not exactly the same as merchant vessels, these structures require crew with expertise in drilling operations. The working conditions can be challenging, and salaries, especially for experienced roles, reflect this.
- Tankers (especially oil and chemical tankers): Tanker ships transport liquids like oil, chemicals, or liquefied natural gas. Due to the potential hazards of these cargoes, specialized training is needed, and crew members usually get a higher salary compared to those on general cargo ships.
- Cruise Ships: While basic crew might not earn as much, top positions like the ship’s captain or chief engineer on a major cruise ship can earn a considerable salary due to the ship’s size, value, and responsibility for passenger safety.
- Dynamic Positioning Vessels: These are specialized ships equipped with systems that allow them to maintain their position despite wind and current. Vessels such as offshore supply vessels for oil rigs, dive support vessels, and cable-laying ships often require a DP (Dynamic Positioning) system. DP Operators, as a result, get a higher salary than many other positions in the merchant navy due to the specialized nature of their job.
- Research and Exploration Vessels: These are often specialized ships employed for scientific research or for exploration (e.g., seismic vessels used for oil and gas exploration). Crew with specific expertise on these ships often earn competitive salaries.
It’s important to note that while these ships might offer higher salaries for certain positions, they may also come with longer working hours, greater responsibilities, and, in some cases, higher risks. Always research a specific position and its associated responsibilities and challenges before making decisions based solely on potential earnings.
What is dry bulk freight?
Dry bulk freight refers to the transportation of unpackaged, non-liquid commodities in large quantities. These goods are often shipped in their raw form and are typically loaded into large vessels, trucks, or train cars specially designed for this purpose. The term “dry bulk” distinguishes these goods from liquid bulk commodities, which are transported in tankers or other containers designed for liquids.
Here are some characteristics and examples of dry bulk freight:
- Unpackaged: Dry bulk commodities are not individually packaged but are loaded in their raw form into the transport vessel’s holds.
- Homogenous: These commodities are typically consistent in nature throughout the shipment.
- Loaded and Unloaded in Bulk: Specialized equipment like conveyor belts, grabs, and chutes are often used for loading and unloading.
- Common Dry Bulk Commodities:
- Grains: Such as wheat, barley, corn, rice, and soybeans.
- Ores: Including iron ore, copper ore, and bauxite.
- Coal: Used for energy production and other industrial processes.
- Cement: A key component in construction.
- Fertilizers: Materials like potash, urea, and phosphate.
- Aggregates: Such as sand, gravel, and crushed stone used in construction.
- Metals: In raw forms, like aluminum or steel billets.
- Soft Commodities: Like sugar or cocoa.
- Wood Chips: Used in paper and pulp industry or for energy.
- Other Minerals: Like salt, gypsum, or limestone.
- Ships: Different sizes of dry bulk carriers, such as Handysize, Handymax (or Supramax), Panamax, and Capesize, are used based on the commodity volume and the ports’ capabilities.
- Rail: Specialized rail cars, like hopper cars, are used for transporting dry bulk commodities overland.
- Trucks: Large dump trucks or trailers can be used for shorter distances or more specific delivery points.
The dry bulk freight market is a crucial segment of global trade, ensuring the movement of primary raw materials from producers to consumers or manufacturers. The rates and demand in this market can serve as indicators of global economic health, with indices like the Baltic Dry Index (BDI) often used as a barometer for the shipping industry and broader economic trends.
What are the types of bulk freight?
Bulk freight refers to the transportation of large quantities of goods that are not packaged separately. These goods can be transported in their natural form without the need for boxes, containers, or other packaging. Bulk freight can be classified into two primary categories: dry bulk and liquid bulk. Let’s explore each:
- Dry Bulk Freight: Dry bulk commodities are solid and are transported in large quantities without packaging. Common dry bulk freights include:
- Grains: Such as wheat, corn, barley, rice, and soybeans.
- Coal: Used predominantly for electricity generation and steel production.
- Iron Ore: Mainly for steel production.
- Bauxite: Used to produce aluminum.
- Phosphate: Often used in fertilizer.
- Cement: Used in construction.
- Metals & Minerals: Other than iron ore, metals like zinc, copper, and nickel, or minerals like salt and sand.
- Aggregates: Materials like gravel and crushed stone.
- Fertilizers: Such as potash.
- Sugars: Raw sugar transported for processing.
- Wood Chips and Pellets: Used in paper production or as a biomass fuel.
- Liquid Bulk Freight: Liquid bulk commodities are liquid goods transported in large volumes. They are typically contained within the tanks of specialized vessels. Common liquid bulk freights include:
- Crude Oil: Extracted from the ground and transported to refineries.
- Refined Petroleum Products: Such as gasoline, diesel, jet fuel, and lubricants.
- Chemicals: Various industrial chemicals and petrochemicals.
- Liquid Natural Gas (LNG): Natural gas that is cooled and condensed into a liquid form for easier transport.
- Liquid Petroleum Gas (LPG): Such as propane and butane.
- Edible Oils and Fats: For instance, palm oil or vegetable oils.
- Wine and Juices: In some cases, these are transported in bulk rather than being pre-packaged.
- Molasses: Used in various industries, including food processing.
For transportation, these bulk goods usually require specialized ships, trucks, or train cars designed to carry the particular type of bulk material. The design considerations ensure the safe and efficient movement of these commodities from their source to their destination.
