Combination Carrier

A combination carrier, often referred to as a "combi carrier," is a type of vessel designed to transport both liquid and dry bulk cargoes. This dual-purpose capability makes them highly versatile and efficient for maritime operations, particularly in routes where the demand for different types of cargo fluctuates.

Design and Features:

• Dual Cargo Holds: Combination carriers are equipped with separate cargo holds that can be used for either liquid or dry bulk cargoes. This allows for flexibility in cargo operations and maximizes the vessel's utilization.
• Structural Integrity: These vessels are built with reinforced structures to handle the different stresses and requirements of carrying both types of cargo.
• Advanced Pumping Systems: For liquid cargoes, combination carriers are fitted with sophisticated pumping systems to ensure efficient loading and unloading.

Operational Advantages:

• Cost Efficiency: By transporting different types of cargo on a single voyage, combination carriers can reduce the need for multiple vessels, thus lowering operational costs.
• Flexibility: The ability to switch between cargo types allows operators to adapt to market demands and optimize their shipping schedules.
• Environmental Benefits: Fewer voyages mean reduced fuel consumption and lower emissions, contributing to more sustainable shipping practices.

Usage in Maritime Industry:

Combination carriers are particularly useful in regions where the export and import demands for liquid and dry bulk goods vary seasonally. They are commonly employed in the transportation of crude oil, petroleum products, and bulk commodities like coal and grain.

Overall, combination carriers play a crucial role in the maritime industry by offering a flexible and cost-effective solution for transporting diverse cargoes across the globe.

Understanding Combination Carriers in Maritime Context

A combination carrier, often referred to as an ore-bulk-oil (OBO) carrier, is a versatile type of ship designed to transport both liquid and dry bulk cargoes. This adaptability allows these vessels to switch between carrying oil, ore, and other bulk materials, thereby minimizing the number of empty return voyages, known as ballast voyages.

What is a Combination Carrier?

In maritime terms, a combination carrier is a ship capable of carrying both wet and dry cargoes. This dual capability is particularly beneficial in reducing the number of empty voyages, as the ship can transport different types of cargo on its return journey. The design of these ships allows them to carry either oil or solid cargoes in bulk, but not simultaneously, except for oil retained in slop tanks.

Examples of Combination Carriers

Combination carriers are not limited to maritime applications. In aviation, for instance, combination aircraft carriers operate with both passenger and freighter aircraft in their fleet. However, in the maritime industry, these vessels are primarily used to transport bulk materials such as ore, coal, and oil.

Combination Carrier as per MARPOL Annex 1

According to MARPOL Annex 1, a combination carrier is defined as a ship designed to carry either oil or solid cargoes in bulk. This definition underscores the vessel's ability to switch between different types of cargo, enhancing its operational flexibility and efficiency.

What is a Combination Ship?

A combination ship is a general term for vessels intended for the carriage of both oil and dry cargoes in bulk. These ships are designed to optimize cargo transport by allowing for different types of cargo on different legs of a journey, thus reducing the need for ballast voyages.

In summary, combination carriers play a crucial role in the maritime industry by offering flexibility and efficiency in cargo transport. Their ability to carry both liquid and dry bulk cargoes makes them an invaluable asset in reducing operational costs and improving logistical efficiency.
