The operation of bulk carriers was not without dangers. Important shipboard issues require cautious planning and prudence. This site is an easy reference for the international shipping industry . It also offers guidance and details on loading and discharge of bulk cargo types. These limits are set by the classification societies. It's important to avoid stressing the structural integrity of the ship and follow all safety procedures for safe sailing at sea. Our detail pages cover a variety of bulk carrier-related topics that might be useful for the crew onboard as well as those working on shore in the terminal.
General characteristics of seagoing bulk carriers
Bulk carriers can be single deck vessels. They have top-side tanks and hopper side tanks. These tanks are used in cargo spaces. They are designed to carry solid bulk cargo. Solid bulk cargo can be any substance, other then liquid or gasoline composed of a mixture of granules and particles. These materials are loaded directly into the vessels cargo space without any sort of containment. Examples of dry cargo are sugar, grain and bulk ore. Bulk carrier, as it is understood in its broadest meaning can refer to any vessel which are designed specifically to transport bulk cargo such as liquid cargo or solid cargo. Tankers would also be included. The term is typically used for ships that transport solid bulk cargos. This would include grains and other agricultural commodities.

What Is A Bulk Transport?
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
-Carrying capability ranging from 3,000 tonnes to 300,000.
Average speed of 12 to 15 knots
-Single deck ships, ie no tweendecks
Carriers with small- to medium-sized bulk (carrying up to 40,000 tonnes) are typically equipped with cargo handling equipment. Larger vessels rely on facilities that are located on shores, which allows for loading or unloading.
The cargo holds are typically big and clear of obstructions. Large hatch sizes make it easy for loading and unloading.
One cargo hold is usually identified as an ballast storage. This can be used for ballast voyages to improve stability. Two or three additional holds are possible to ballast in part at port, but only
They can be covered by single pull or hydraulic, or stacking (piggyback) type steel hatch covers
Quatre types of ballast tanks
Sloping topside wing tanks
Sloping bottom side wing tanks
Double bottom tanks
Post peak and peak peak ballast water tanks
Are you in search of bulk solid cargo? Solid bulk cargo refers to any substance other than liquids or gases that is made up of grains, particles or larger pieces and which can be loaded directly into the cargo area without additional container. It is imperative to make sure that all cargoes are ready to be loaded, regardless of whether they're "clean" or "dirty" and there isn't any contamination. A surveyor is often required to inspect the space and determine if it is suitable to be loaded. To prevent contamination, it's essential to get rid of any remnants left from earlier cargo. Water is the main reason for destruction to bulk cargoes. Therefore, it is vital that the holds are dry in order to receive cargo. Hatch covers must be watertight to prevent water from getting in. All fittings inside the container (ladders pipe guards, ladders, bilge, etc.) should be inspected. To make sure they are in good condition and correctly fitted to the hold (ladders and pipe guards, bilge covers etc.) must be examined. The equipment may cause significant damages to conveyor belt systems and consequent delays, for which the ship could be held accountable, should they accidentally discharge the cargo.

Bulk Carrier, Bulker? It is built to carry dry cargo. Conventional bulk carrier is constructed with one deck, a one skin and double bottom. It also has topside tanks, and side tanks that are located in cargo areas. Bulk carriers can load any type or bulk cargo from heavy to light grain up to their maximum deadweight. The loading, transportation and then the discharge of bulk cargo that is dry isn't as straightforward or straight-forward as people think.
Gearless Bulk Carrier
Certain bulk cargoes can be dangerous and may be damaged throughout the journey. Unsafe loading could cause damage to the ship. A vessel that isn't loaded to its maximum forward could be bent if you load it excessively. This is known as stress. When the weather is rough, this can cause serious problems at sea. Other cargoes can also be affected by residues from previous cargoes. Certain bulk cargoes could be affected by water damage, e.g. cement power. It is difficult to verify the quantities and weights of cargoes loaded and unloaded. All these factors have serious impact on the security of bulk cargoes. Discharging bulk cargo using? bulk cargoes are prone to having the tendency of forming a cone whenever they are loaded if conveyor belts and similar systems aren't monitored and monitored. This angle is known as the "angle of repose" and is different based on each cargo. Cargoes made of iron ore for instance, can make an cone with an angle. Cargoes that are free to move freely will form the cone with a narrow angle. Cargoes with low angles of repose tend to move during transit. When the cargo is nearing its completion, bulldozers could be required to spread the load in the hold. Dry-bulk carriers depend on dock facilities to facilitate discharge and loading of cargo. However, bulk carriers may offer self-unloading with conveyors under the cargo holds or on decks.
