Understanding Ocean Transport: Maritime and Bulk Freight Shipping

Definition and importance of ocean freight in global trade

‍

Ocean freight, also known as ocean cargo shipping, refers to the transportation of goods or commodities by carrier vessels across seas and oceans. It plays a vital role in the global trade and supply chain network, cost-effectively transporting large volumes of goods.

‍

Over 90% of world trade by volume is transported via maritime shipping, making it a crucial lifeline for the transfer of merchandise of all types.

‍

Overview of the types of goods transported via ocean freight

‍

Goods transported via ocean freight transport includes raw materials like coal, iron ore, and grains; energy products like oil and LNG; finished products like automobiles and electronics; and containerized cargo carried in intermodal shipping containers. 

‍

Bulk cargo, liquid cargo, refrigerated cargo, and general cargo are the main types of cargo shipped in specialized carrier vessels based on the characteristics of the goods.

‍

Historical Evolution and Current State of Maritime Shipping

‍

Maritime transport and trade have evolved over centuries, from native sailing boats plying along coastal routes to modern container ships, tankers, and dry bulk carriers sailing global routes. 

‍

The advent of standard-sized shipping containers in the 1950s revolutionized ocean shipping with faster handling of cargo. The opening of the Suez and Panama canals also boosted global maritime trade by connecting the Atlantic with the Indian and Pacific oceans.

‍

At present, about 90% of world trade is seaborne. Ships have increased dramatically in size for economies of scale. Efficiency has improved with better port infrastructure, loading/unloading, and tracking technology. 

‍

Environmental sustainability has become a priority with regulations for cleaner fuels, ship recycling policies, and route optimization to reduce the carbon footprint.

‍

With seaborne trade volumes projected to rise driven by growth in emerging economies, maritime shipping and its constant evolution will remain the backbone of a globalized world economy.

‍

But wait, there's more to it than just big ships and vast oceans. Let's dive into the specifics of the types of ocean freight shipping.

‍

Types of Ocean Freight Shipping

‍

‍

Full Container Load (FCL) vs Less Than Container Load (LCL)

‍

The two main types of containerized shipping are FCL and LCL. With Full Container Load or FCL, a shipper rents an entire container just for their cargo. This allows greater control and security of goods. FCL is more cost-effective for large-volume shipments. 

‍

Less Than Container Load or LCL involves consolidating multiple partial shipments from various shippers into one container to optimize space. This is suited for small-volume shippers. The container is deconsolidated at the destination port.

‍

Bulk freight shipping for non-containerized goods

‍

Bulk cargo refers to unpackaged mass commodities like grains, coal, ore, etc. transported in large quantities. These are loaded directly into the holds of bulk carriers or tankers equipped for that cargo. 

‍

As no packing is required, it is the most efficient mode to ship large volumes of homogenous cargo. Liquid bulk includes crude oil, petroleum, chemicals, liquefied natural gas, etc. Dry bulk commodities are ores, coal, grains, etc. Bulk shipping is vital for moving these essential commodities around the world.

‍

Specialized freight: Oversized, Break Bulk, and Dangerous Cargo

‍

Reefer or refrigerated container vessels can control the temperature to transport perishable goods of meat, fruits, medicines, etc. over long distances. Oversized cargo ships move abnormally large pieces like turbines, rigs, boats, etc. that don't fit normal containers. 

‍

Break bulk refers to goods too large for a container but too small for a bulk vessel e.g. machinery, timber, and steel coils. Dangerous goods like hazardous chemicals need special handling and storage and are transported in tank containers or dedicated dangerous goods vessels adhering to strict safety norms.

‍

Got all that? Great! Let's navigate towards how these shipping wonders are chartered and partially chartered.

‍

Chartered and partial-chartered services

‍

A shipping customer can charter or lease the entire vessel capacity for an agreed time. This assures space and availability. Partial chartering books a specific slot or portion of the ship, providing more flexibility for fluctuating cargo volumes.

‍

The unused vessel space is allotted to other partial charter customers. Charter agreements specify terms for booking space, volume committed, freight rate, etc. Charter hire depends on shipping demand dynamics, vessel position, etc. Customers wanting more control over shipping opt for long-term contracts with liners.

‍

Key Components of Ocean Shipping

‍

Ships and Fleets: Types and Their Purposes

‍

The main vessel types are container ships, bulk carriers, tankers, roll-on/roll-off ships, refrigerated ships, and general cargo. Container ships transport containerized cargo of all types. Bulk carriers move large volumes of commodities like iron ore, grains, or coal. 

‍

Tankers carry petroleum products, oil, chemicals, and liquefied gas. Ro-Ro ships handle wheeled cargo moved via ramps. Reefer ships have temperature-controlled containers. General cargo ships carry packaged products, equipment, project cargo, etc. Modern fleets deploy ultra-large vessels that offer economies of scale.

‍

Container types and their attributes

‍

Containers come in 5 standard lengths - 20 ft, 40 ft, 45 ft, 48 ft, and 53 ft. Common types are general-purpose dry vans for diverse products, insulated containers to control temperature, ventilated boxes with slots for fruits/vegetables, open tops for oversized goods, flat racks to carry machinery, and tanks for bulk liquids. 

‍

Containers have standardized dimensions that stack securely on ships with quick transfer between modes - ships, rail, and trucks.

‍

Ports and their roles in worldwide logistics

‍

Ports connect marine travel with inland transport enabling the transfer of imported and exported freight. Key port functions are cargo handling via cranes/forklifts, storage yards to stock containers, intermodal links to rail/trucks through road/rail networks, and freight stations for documentation. 

‍

Efficient ports invest in the newest cargo gear for quicker ship turnarounds. Top global transit hubs with the best infrastructure and connectivity are critical for seamless freight flows.

‍

The role of freight forwarders and ocean freight carriers

‍

Freight forwarders facilitate transport on behalf of shippers. They plan optimal routes, prepare shipping documents, negotiate freight rates, and track and trace cargo while maintaining close coordination between origin, destination agents, and carriers. 

‍

Most carriers focus on assets, networks, and moving freight. Freight forwarders organize logistics tailored to customer needs taking responsibility for successful door-to-door delivery. 

‍

Carriers offer shipping capacity and services while freight forwarders sell customized logistics by leveraging carriers, routes, and container options in a cost/time-effective way.
