The operation of seagoing bulk carriers was fraught with dangers. You should plan well and exercise caution in dealing with all shipboard issues. This site was created to be a quick guide for shipping organizations around the world. It provides details and guidance on loading and unloading bulk cargo types. The website must stay within the limitations set by the classification society. It is vital to limit the possibility of ship structural stress, and to adhere to all necessary safety measures for safe passage at Sea. You might find useful details on bulk carrier issues on our pages of detail, both for those working at sea and those ashore.
General characteristics of seagoing bulk carrier
Bulk carriers are single-deck vessels constructed with top-side tanks as well as side tanks for hoppers within cargo spaces . They are designed primarily to carry single-commodity solid bulk cargo. Any substance that is not liquid or gas but solid bulk cargo, includes any material consisting of a mixture or granules, or any other material with an identical composition. The material can be loaded directly into the cargo area of a ship and does not require containment. Dry cargo includes sugar, grains, and bulk ores. The bulk carrier is a ship which is used for transporting bulky or liquid cargo. This would also include tankers. In ordinary usage, however, the term is normally used for those vessels designed for the transport of bulk solid cargos, usually grain and similar agricultural products, and mineral products like stone, coal, ore, etc. and on one or more voyage legs.

What Exactly Is Bulk Carrier?
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
-Carrying capacity varying between 3,000 and 300,000 tonnes
The average speed is 12-15 knots
-Single deck ships, ie no tweendecks
-small to medium sized bulk carriers (carrying capacity up to 4000 tonnes) generally include cargo handling equipment with larger vessels. Larger vessels use dock-based facilities for loading and unloading
-Cargo holds are often big and clear of obstructions. Large hatch sizes make it easy for loading/unloading.
The bulk carriers typically have one ballast hold. This is a great way to increase stability during ballast voyages. It is also possible to ballast part of the way, however it is only permitted for port.
They are able to be used as single-pull, hydraulic, or stacking (piggy back) steel hatch covers.
Four types of ballast tanks:
Sloping topside wing tanks
The bottom of the wing is sloping. tanks
Double bottom tanks
Ballast during peak times and after that in the peak tank.
What is a solid bulk cargo? Any material other than gasoline or liquid comprised of the mixture of smaller pieces that are uniform in composition and loaded directly into cargo space. Bulk carriers can transport a variety of cargoes, comprising "clean" food products and "dirty", minerals, in addition to cargoes that could interact with each other or other contaminants such as water. It is essential to make sure that the space is ready for the specific cargo. Cleaning must be adequate to allow the cargo to be loaded and typically, a surveyor is required to assess the space to ensure it is suitable to load. To prevent contamination from occurring it is essential that any leftovers left by a previous cargo be removed. Damage to bulk cargoes can be due to water. Thus it is essential that not only the holdings be dry for cargo to be able to enter, but hatch covers must be watertight or, when necessary sealed to prevent the entry of water. All fittings within the hold (ladders pipes, ladders, bilge covers, etc.) To ensure they are in good working order and properly fitted to the hold (ladders and pipe guards, bilge covers etc.) must be examined. Such pieces of equipment might cause major damage to conveyor belt systems and, consequently, delays for which the ship will be held liable, should they accidentally discharge the cargo.

Bulk Carrier, Bulker It is built for transporting dry cargo. The bulk carrier of the conventional type has one deck and a single skin. Bulk carriers are designed to carry bulk cargo of any size either light or heavy, and can carry a maximum weight of 450 pounds. The loading, carriage and then the discharge of dry bulk cargo isn't as easy or straightforward as many people imagine.
Gearless Bulk Carrier
A lot of bulk cargoes may be dangerous or alter their properties during transport. Unintentional loading can cause damage to the vessel, e.g. It is possible for a ship to bow if not properly loaded. This is known as stress? This can lead to dangers to life at sea, particularly in severe weather. Other cargoes may also be affected by residues from prior cargoes. Certain bulk cargoes such as cement power, are also susceptible to water damage. cement power. It is hard to determine cargoes loaded or discharging. These elements can have severe consequences on how bulk cargoes are transported safely. Discharging bulk cargo using? bulk cargoes are prone to having an inherent tendency to form a cone whenever they are loaded when conveyor belts or similar systems are not supervised and monitored. The angle of this cone, which is also known as the "angle for repose", varies with each cargo. For iron ore, cargoes may create a cone with a steep angle. However, cargoes that flow freely can make a shallow angle cone. A cargo with an angle that is low to rest is more susceptible to shifting during passage. When the cargo is nearing completion, bulldozers might be required to spread the load across the holds. Dry-bulk carriers depend on shoreside facilities for cargo loading/discharge. However bulk carriers could offer self-unloading with conveyors under the cargo holds or on decks.
