Classification of bulk cargo ship




Bulk cargo ships can be divided into different types according to different loads, mainly as follows:

Coal ship
A coal ship is a bulk cargo ship used for loading and transporting coal. Its hatch is relatively wide, making it easy to load and unload coal with a grab bucket. In order to prevent coal from rolling in the coal bunker, many longitudinal baffles are provided at the bottom of the coal bunker. Some coal ships do not use grabs and booms, but are equipped with belt conveyors at the bottom of the coal bunker, which can be connected to shore conveyors and can load and unload coal by themselves

Ore Ship
An ore ship is a bulk cargo ship that specializes in loading sand. Because the ore is a heavy cargo, it has a large specific volume and a small volume, which can easily damage the hull. For this reason, the ore ship has a strong structure. The bottom of the cargo hold is mostly inclined. The cargo hold is also equipped with longitudinal baffles, which can prevent the ore from rolling longitudinally and increase the strength of the hull.

Wooden ship
Wooden ships are used to load and transport timber ships, due to the light weight and large volume of wood. Therefore, the cargo hold of the wooden ship is wide, and there are no hull components such as beams and columns in the cargo hold. Also, because the wood is not afraid of wind and rain, it can be installed in the cargo hold or stacked on the deck. In order to block and enclose the timber, wooden posts are arranged on the side of the deck so that more timber can be installed.

Bulk carriers can be divided into different types according to different transportation purposes, mainly as follows:

Ordinary Bulk Carrier
Ordinary bulk carriers are generally single-deck, stern type, and the cross section of the cargo hold is octagonal. Due to the single type of cargo transported, the requirements for compartment separation are not high, and the specific gravity of various bulk cargoes vary greatly, the bulk cargo ship's cargo compartment volume is relatively large to meet the requirements for loading light cargo. When heavy cargo needs to be loaded, the method of compartment loading or the arrangement of large and small compartments shall be adopted.

Dedicated bulk carrier
Special bulk carriers are bulk carriers designed and built according to the special requirements of some large quantities of bulk cargo for maritime transportation technology, mainly including coal carriers, bulk grain carriers, ore carriers, and bulk cement carriers.

Double-use bulk carrier
The dual-purpose bulk carrier is a ship designed and built according to the special requirements of certain specific bulk cargo or bulk cargo for maritime transportation technology, and has a variety of shipping functions.

Special bulk carrier
Large-hatch bulk carrier: This type of ship has a cargo hatch width of more than 70% of the ship's width and is equipped with lifting equipment. It can load bulk cargo as well as wood, steel, rubber, machinery, newsprint and containers. Wait, it is very adaptable.

Self-unloading bulk carrier: a transport ship with a special cargo hold structure and an automatic unloading system. It can carry out centralized operation and fast automatic unloading operations without relying on port facilities, and is suitable for transporting bulk ore, grain, coal, cement, fertilizer, etc.

Livestock ship
Livestock ships are bulk cargo ships that specialize in transporting livestock. In order to prevent livestock from moving in the cabin, partitions are provided in the cabin of the livestock ship, and there is also a food trough in the cabin for livestock food.

Grain ship
A grain ship is a bulk cargo ship that specializes in transporting grain. It belongs to the category of dry bulk carriers.

Cement ship
Cement ships are bulk cargo ships that specialize in transporting cement. It belongs to the category of dry bulk carriers.

Steel carrier

A steel carrier is a bulk carrier that specializes in shipping steel. It belongs to the category of dry bulk carriers.
