The operation of bulk carriers involved numerous hazards. Careful planning and exercising due care for all important issues on the ship's deck are essential . This site provides quick guidance to the international shipping community and information regarding loading and discharging various bulk cargo types. It is important to remain within the limitations set out by the classification agency. It is vital to limit the risk of a ship's structure being stressed, and to comply with the safety requirements to ensure safe passage on the sea. There are detail pages on our website which cover a variety of topics that concern bulk carriers. They are helpful both for those onboard and those who are ashore at the terminal.
The general characteristics of bulk seagoing ships
Bulk carriers are single-deck vessels that are fitted with top-side tanks and side tanks. They are designed for single-commodity bulk cargo. Bulk cargo that is solid can refer to any material, apart from gasoline or liquid, that is comprised of a mixture of granules and particles. They can be loaded directly into the vessels cargo space without any sort of containment. Dry cargo includes sugar, grains, and bulk ores. In the broadest sense of the word the term "bulk carrier" encompasses all vessels designed to transport liquid or solid cargo in bulk form, and so would include tankers. In the context of common usage bulk carriers are utilized to transport bulk goods that are solid. This is a reference to grains and other agricultural products along with minerals like coal, iron ore, stone and coal. Have a look at this dry bulk shipping info for more.
What Is A Bulk Carrier What Are The General Characteristics Of Bulk Carriers? Are:
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
-Carrying capability that ranges from 3,000 to 300,000.
Average speed 12-15 knots
-Single deck ships, ie no tweendecks
small to medium sized bulk carriers (carrying capacities up to 4000 tonnes) generally include cargo handling equipment, while larger vessels use shore based -facilities for loading and unloading
-Cargo hold dimensions are generally big free of obstructions. They also have larger hatch sizes that permit easy loading and unloading.
One cargo hold is usually classified as an ballast storage. This can be used for ballast voyages to improve stability. One or two more holds could be permitted for ballasting partial in port, but only for a limited time.
They can be used as single-pull, hydraulic or stacking (piggy back) steel hatch covers.
Four types and sizes of ballast tanks:
Sloping topside wing tanks
Sloping bottom side wing tanks
Double bottom tanks
Post peak and peak peak ballast water tanks
Bulk solid cargo? Anything other than gasoline or liquid made up of the mixture of smaller pieces that are uniform in composition, and loaded directly into cargo spaces. It is essential to ensure that all cargoes you carry are ready for loading, regardless of whether they are "clean" or "dirty" and there is no contamination. A surveyor is often required to look over the area and determine if it is suitable to be loaded. It is vital that the remnants of previous cargo be removed to ensure that no contamination will occur. Bulk cargo damage is mostly due to water. To avoid water intrusion, hatch covers must be watertight. All fittings inside the storage area (ladders pipe guards, ladders and bilge pipes.) are to be examined. All fittings inside the hold (pipe guards and bilge covers.) are to be examined to make sure they are in proper condition and securely fixed. They may cause serious damage to conveyor belts, which could cause delays. If the equipment is discharged accidentally with cargo, the ship might be held accountable.

Bulk Carrier, Bulker This vessel is intended to carry dry cargo. A traditional bulk carrier is equipped with a single deck, single skin and double bottom. It also contains topside tanks and cargo space tanks. Bulk carriers are designed to load a maximum deadweight of any type of bulk cargo including heavy ore and light grain . It can be difficult to move, load and unload dry bulk cargo.
Gearless Bulk Carrier
Certain bulk cargoes can be dangerous and could be altered during passage. A wrong loading could cause damage to a ship. The ship can bend if it is loaded at the maximum forward holding. This can cause the vessel to'stress'. These can have serious consequences for the sea's life during extreme weather conditions. In addition, leftovers from earlier cargoes could have a serious impact on the future cargoes. Some bulk cargoes can also be affected by water damage, e.g. cement power. It's not easy to verify true quantity or weight of cargoes being discharged or loaded. Each of these aspects affect the methods of operation to ensure the safety of bulk cargoes. Discharging bulk cargo using? conveyor belts and similar systems are not monitored and supervised the bulk cargoes form an elongated cone. The angle created by this cone is referred to as the `angle of repose'. It is different depending on the cargo. Cargoes like iron ore can form a steeply angled cone. But, cargoes that flow freely could form a shallow angle cone. cargoes with lower angles of repose are more likely to move through the course of transport. As the cargo nears the point of completion, bulldozers might need been used to divide the load across holds. The majority of dry bulk carriers rely on shoreside facilities to discharge cargo and load it onto the shores however certain bulk carriers come with self-unloading capabilities with conveyors underneath the cargo hold or cranes on the deck.
