Everything You Need to Know About Dry Bulk Shipping
One of my favourite global shipping stats is that 90% of the world's shipping is done through the ocean. This begs the question: is it only consumer goods that make up this number? The answer is no.
The dry bulk shipping market makes up a good number of the earlier stated percentage. This article will explore this market, including what it is, what it transports, how it is transported, and other elements that make up the market. It is a lot to take in, but first, let us look at what dry bulk shipping is.
What is Dry Bulk Shipping?
Dry bulk shipping is the transportation of unpackaged, loose raw materials in large quantities. These materials, known as dry bulk cargo, are not packed in containers or bags but are loaded directly into the ship's hold. Common examples of dry bulk cargo include grains, coal, iron ore, and other minerals.
The dry bulk shipping process involves specialised ships called bulk carriers or bulkers. These carriers are designed specifically to carry large amounts of dry bulk cargo. They have large, open holds that can be easily loaded and unloaded using cranes, conveyor belts, or other equipment at ports.

Why Dry Bulk Shipping Matters
Dry bulk shipping plays an important role in global trade for the following reasons:
Essential Commodities:
Many of the materials transported as dry bulk cargo, such as iron ore, coal, and grain, are essential for various industries. Iron ore is used in steel production, coal is a significant energy source, and grains are vital for food production. Supplying these materials to different parts of the world would be challenging without dry bulk shipping.
Cost-Effective Transportation:
Dry bulk shipping is one of the most cost-effective ways to transport large quantities of raw materials over long distances. The efficiency and scale of bulk carriers make them a cheaper option compared to other forms of transportation.
Supports Global Trade:
The movement of dry bulk cargo supports international trade by enabling countries to import and export essential resources. Countries rich in natural resources can export their surplus, while countries lacking these resources can import them to meet their needs.
Economic Impact:
The dry bulk shipping industry impacts the global economy. It supports and facilitates job creation, from shipbuilders and crew members to port workers and logistics professionals.
Types of Dry Bulk Cargo
Bulk cargo is categorised into major and minor bulks. Let's explore different types under each category;
Major Bulks
Iron Ore:
Iron ore is a key raw material used to produce steel used for building infrastructure, manufacturing vehicles, etc. Because of its importance, iron ore is one of the most transported commodities in the world. Large ships called "Capesize" vessels transport iron ore because they can carry large amounts.
Coal:
Coal is another major bulk commodity with global importance. It is burned in power plants to generate electricity. It is also used in industrial processes such as the production of cement and the manufacture of steel.
Grain:
Grain shipments are needed to feed the world's population. Grains like wheat, corn, and rice are staple foods for billions of people and are essential for food security. They are usually transported in "Handysize" and "Panamax" vessels, which are well-suited to carry bulk agricultural products.
Minor Bulks
Bauxite/Alumina:
Bauxite is the primary raw material used to produce alumina, which is then used to make aluminium. Aluminium is needed in various industries, including construction, transportation, and packaging. The conversion process involves mining bauxite and shipping it to refineries, where it will be processed into alumina. This alumina is then transported to smelters and converted into aluminium.
Fertilisers:
Fertilisers are vital for agriculture as they provide essential nutrients that enhance plant growth and increase crop yields. They are transported in bulk carriers or specialised ships.
Cement:
Cement is a key material in the construction industry. It is used to make concrete and for building infrastructure such as roads, bridges, and buildings. Once produced, cement needs to be shipped quickly to prevent it from setting. It is usually transported in specialised bulk carriers with systems to keep the cement dry and to facilitate easy unloading.
Forest Products:
These include logs, wood chips, and pulp used in paper production and construction. They are shipped in bulk carriers with specialised handling equipment.
Sugar:
This is used in the food and beverage industries. It is transported in bulk carriers, ensuring it remains dry to prevent it from getting bad.
Dry Bulk Shipping Vessels
Dry bulk shipping vessels are specifically designed to transport unpackaged bulk cargo, and they come in various sizes, which include:
Bulk Carriers
Handysize:
Handysize bulk carriers are the smallest, ranging from 10,000 to 35,000 deadweight tons (DWT). They are versatile and can access smaller ports that larger ships cannot. Common cargoes for Handysize vessels include grains and fertilisers.
Handymax:
Handymax bulk carriers are slightly larger, with a 35,000 to 50,000 DWT capacity. They share similar versatility with Handysize vessels but can carry more cargo, making them efficient for routes larger vessels cannot go through. Common cargoes include coal, grains, and ores.
Supramax:
Supramax bulk carriers have a capacity ranging from 50,000 to 60,000 DWT. These ships have onboard cranes, which allow them to load and unload cargo in ports that lack such facilities. Supramax vessels commonly transport minerals, coal, and agricultural products.
Panamax:
Panamax bulk carriers are designed to fit through the Panama Canal and have a maximum capacity of about 65,000 to 80,000 DWT. They are larger than Supramax vessels and commonly transport grains, coal, and ores on routes that pass through the Panama Canal.
Capesize:
Capesize bulk carriers are the largest, with capacities over 80,000 DWT, often reaching up to 200,000 DWT or more. These vessels are too large to pass through the Panama or Suez Canals and must travel around the capes of continents, such as the Cape of Good Hope. They transport heavy cargoes like iron ore and coal over long distances.
Specialised Carriers
OBO (Ore-Bulk-Oil) Carriers:
OBO carriers are versatile ships that carry ore, bulk, and oil cargoes. Their flexibility allows them to switch between different types of cargo without needing to return to a specific loading port.
VLOC (Very Large Ore Carrier):
VLOCs are specialised vessels designed to carry large quantities of ore, typically with capacities exceeding 200,000 DWT. These ships transport iron ore from large mining areas like Brazil and Australia to major industrial regions like China.
Self-Unloading Vessels:
Self-unloading vessels are bulk carriers with conveyor belts or other mechanical systems that unload their cargo without needing to use port unloading equipment.
Gearless vs. Geared Vessels
Geared Vessels:
Geared vessels are equipped with their onboard cranes and other cargo-handling equipment. This allows them to load and unload cargo in ports that lack suitable infrastructure. Geared vessels are useful in developing regions or smaller ports where shore-based cranes and handling facilities are limited or nonexistent.
Gearless Vessels:
On the other hand, Gearless vessels do not have onboard cargo-handling equipment and rely entirely on port facilities for loading and unloading. These ships are generally more efficient and have a larger cargo capacity since they don't carry the weight and space of cranes.
The Dry Bulk Shipping Market
This is a complex market that would require a lot of people and systems to operate. We will explore some of the key elements that keep this market together:
Key Players
Shipowners:
Shipowners are individuals or companies that own the vessels used for transporting bulk cargo. They are responsible for maintaining the ships and ensuring they are seaworthy.
Charterers:
Charterers are individuals or companies that hire vessels from shipowners to transport their cargo.
Brokers:
Brokers act as intermediaries between shipowners and charterers. They help negotiate contracts, arrange charters, and facilitate communication. Brokers earn commissions for their services and are needed to match available ships with cargo needing transport.
Freight Rates
Freight rates are the prices charged for transporting bulk cargo. These rates are influenced by several factors and are tracked by indices like the Baltic Dry Index (BDI).
Baltic Dry Index (BDI):
The BDI measures the average daily shipping rates for bulk cargo. It is calculated by assessing rates across different shipping routes and vessel sizes. The BDI provides an overview of the overall health of the dry bulk shipping market and is a key performance indicator for industry stakeholders.
Factors Influencing Freight Rates
Some of the factors that influence freight rates are:
Supply and Demand:
Freight rates increase when there is high demand for shipping but limited vessel availability. And, when there is an oversupply of ships, rates decrease.
Vessel Availability:
The number of available ships directly affects freight rates. If many ships are in dry dock for maintenance or other reasons, rates can rise.
Fuel Prices:
Fuel costs are part of operating expenses. Higher fuel prices increase shipping costs, leading to higher freight rates.
Port Congestion:
Delays at ports due to congestion can affect vessel availability and increase freight rates.
Global Trade Volumes:
The overall volume of global trade impacts the demand for shipping services and freight rates.
Seasonality
Weather Patterns:
Weather conditions like storms and hurricanes can disrupt shipping routes and schedules, leading to delays and increased freight rates.
Agricultural Cycles:
Crop production and harvest cycles influence the demand for bulk carriers. For example, the harvest season for grains in major exporting countries increases the demand for shipping vessels to transport these commodities to global markets.
Economic Factors
Economic conditions, such as growth or recession, impact industrial production and trade volumes. Economic booms will increase demand for raw materials and more shipping activity.
Wars and Conflicts
Wars and regional conflicts can disrupt major shipping routes, leading to delays and increased insurance costs. This can reduce vessel availability and increase freight rates.
Sanctions
International sanctions against certain countries can restrict trade routes and limit the availability of certain shipping services, impacting the global shipping market.
Trade Policies
Changes in trade policies, such as tariffs and import/export restrictions, can influence the volume of goods being shipped and affect freight rates.
