Seagoing Bulk Carrier The General Purpose and Use

There were many risks involved in the operation of sea-going bulk carriers. Important shipboard issues require the use of a careful plan and care. This site is an easy reference for the international shipping professionals with guidelines as well as information regarding the discharge and loading of different bulk cargo types . It is to be within the restrictions as specified by the classification society. It is essential to make sure that the ship's structure is not stressed and all safety precautions are taken in order to ensure safe passage in the ocean. Our detail pages provide information on a variety of bulk carrier-related topics that could be of interest to those working on board or ashore at the terminal.

The general characteristics of bulk ships that travel by sea.
Bulk carriers are equipped with a single deck and include top-side and hopper tanks. They are able to carry bulk cargo, which is a single product. Bulk cargo that is solid can be any substance, other then liquid or gasoline, that is comprised of a combination granules and particles. These materials can be loaded directly into the ship's cargo spaces without any kind of container. These dry cargoes include bulk grains, sugar and ores. Bulk carriers can be described as any ship that is designed to carry liquid or solid bulk cargo. Tankers can also be included. However, in normal usage, the term is generally applied to vessels that transport bulk loads consisting of solid items, including grain and other agricultural goods and minerals items like coal, ore, or stone for a few or one travel legs.

What Is A Bulk Vessel?

"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"

The carrying weights vary from 3,000 tonnes up to 300,000.
-Average speed of 12-15 knots
-Single deck ships, ie no tweendecks
Small to medium size bulk (carrying capacities between 40 and 60,000 tonnes) generally have equipment for handling cargo. However larger vessels may use facilities on shore to load or unload.
-Cargo holds that are large are free of obstructions and have bigger hatch sizes for ease of loading/unloading.
The majority of bulk carriers have a ballast hold. It can be utilized on ballast voyages in order to improve stability. A couple of additional holds may be permissible for ballasting partial in ports, but only
They are single pull and stacking, or hydraulic steel hatch covers.
-Quatre types of ballast tanks
Sloping topside wing tanks
Sloping bottom side of wing tank
Double bottom tanks
After-peak and peak ballast water tank.

Bulk solid cargo? Any other than liquid or gas substance that is a mixture of particles and granules. It can be brought directly into areas of cargo without the need for intermediate storage. The bulk carriers that transport cargo comprise "clean" foodstuffs as well as "dirty" minerals. They can react with each other and with contamination sources such water. This is why it is vital to clean the cargo areas for the specific cargo. It is important to clean the cargo spaces in order to load it. Surveyors are typically required to verify that the area is clean to be loaded. To prevent contamination from occurring it is essential that any residue left behind by previous cargoes be taken away. Damage to bulk cargo is usually caused by water. To stop water from entering hatch covers should be watertight. All fittings within the storage area (ladders pipes, ladders as well as bilge covers.) All fittings in the hold (pipe guards, bilge covers.) must be checked to ensure that they are in good condition and securely fastened. These pieces of equipment could cause serious damage to conveyor belt systems and, consequently, delays and the ship would be held accountable, should they accidentally discharge the cargo.

Bulk Carrier or Bulker? A vessel that is designed to transport dry cargo, loaded into the vessel without any containment other than that of the ship,s boundaries in contrast to the bulk carrier that is liquid or tanker. The conventional bulk carrier is built with one deck, a one skin double bottom, topside tanks, and side tanks within cargo spaces. Bulk carriers are constructed to handle bulk cargo of any weight either light or heavy, and have a maximum load of 450 pounds. It's not as easy or as simple as you think.

Gearless Bulk Carrier
Many bulk cargoes may have dangerous properties or undergo changes in transport. Uncorrect loading can cause the ship to be damaged easily. There is a possibility for the ship to bow when it is not properly loaded. This stress If the weather is bad, this can cause serious problems at sea. Other cargoes could be impacted by residuals from other cargoes. Damage from water can have a devastating effects on certain bulk goods e.g. cement power. It is not always easy to verify the exact weights of cargoes that have been loaded and removed. All of these factors have serious consequences for safe bulk cargo transport. Discharging bulk cargo using? Bulk cargoes possess an inherent tendency to form a cone when they are loaded if conveyor belts and similar systems are not supervised and controlled. The angle formed by the cone is referred to as 'angle of repose'. It varies between cargos. Iron ore-based cargoes for instance, will form an cone with an angle. Cargoes that are free to move freely will form the cone with a narrow angle. A cargo with a low angle to repose is more prone to shifting throughout the passage. When cargo is nearing the point of completion, bulldozers might need been used to divide the load into holds. Most dry-bulk carriers depend on dock facilities for loading and discharging cargo, but certain bulk carriers come with self-unloading capabilities with conveyors underneath the cargo holds or with cranes mounted on deck.
