Seagoing Bulk Carriers: Purpose and General Use
Operation of sea going bulk carriers was not without dangers. The safety of seagoing bulk carriers is a matter of meticulous preparation. This site serves as a quick reference to the shipping industry in general and offers guidance and details on loading and discharge of bulk cargo types. These limitations are set by the classification societies. It is essential to minimize the chance of stressing too much on the ship's structure , and complying with all essential safety measures for a secure sea crossing. The detail pages on our website cover various bulk carrier-related topics which could be beneficial to people working on board and those working on shore at the terminal.
General features of a seagoing bulk carrier
Bulk carriers are single-deck vessels that are equipped with top-side tanks as well as side tanks. They are designed to carry bulk cargo of a single commodity. Solid bulk cargo is any substance, other than liquid or gas, consisting of a combination of granules, particles or any other large chunk of material that is generally uniform in composition, which is loaded directly into cargo spaces of a ship without any immediate form of containment. Dry cargo can include bulk grains, sugar, and even ore. In the broadest sense, the term bulk carrier encompasses all vessels designed to carry liquid or solid cargo in bulk form, and so would include tankers. The term is used primarily for vessels that carry solid bulk cargos. This could include grains and similar agricultural products. Peruse this dry bulk carrier blog for more.

What Is A Bulk Ship?
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
-Carrying weights range from 3,000 tonnes to 300,000.
Averaging speed of 12-15 knots
-Single deck ships, ie no tweendecks
Carriers with medium to small size bulk (carrying capacities between 40 to 60,000 tonnes) typically have cargo handling gear. However, larger vessels can use facilities on shore to load or unload.
Large cargo holds have no obstructions and bigger hatch sizes for ease of loading and unloading.
Ballast holds are a standard feature on bulk carriers. This can be used during ballast voyages to improve stability. Two or three additional holds may be permitted to ballast partially, but only when in port.
They are available in single pull or stacking (piggyback) and type hatch covers made of steel.
Quatre ballast tanks are the most common types.
Sloping topside wing tanks
Sloping bottom side-wing tanks
Double bottom tanks
Ballast during peak times and after that in the peak tank.
Solid bulk cargo? Anything other than gas or liquid, made up of a mixture of particles, granules or any larger pieces of material generally uniform in composition, and loaded straight into the cargo space without any intermediary form of containment. Bulk carriers can carry diverse cargoes including "clean" food products and "dirty", minerals, in addition to cargoes that may react one with the other or with other sources of contamination, such as water. It is essential to make sure that the space is ready for the specific cargo. The cargo area needs to be cleaned in a way that allows loading. Surveyors often have examine the area to ensure it is safe to load. It is vital that the leftovers from previous cargo be removed to make sure that contamination doesn't occur. The damage to bulk cargoes is mainly due to water. The hold must be dry to receive cargo. But, hatch covers must be watertight, or sealed as needed to keep water out. All fittings in the hold (ladders pipes, ladders as well as bilge covers.) You must inspect each fitting inside the hold (ladders,pipe guards, bilge covers...) to make sure that they are in good working order. They can cause significant wear and tear to conveyor belts, which could lead to delays. If the equipment is accidentally discharged by cargo, the vessel may be held responsible.

Bulk Carrier, Bulker Bulk Carrier, Bulker? A vessel that can carry dry cargo. It's not meant to be a bulk liquid tanker or carrier. Traditional bulk carriers are equipped with a single deck with single skin, double-bottom, hopper side and topside tanks. Bulk carriers can be used to transport heavy ore as well as light grain with their greatest weight. The loading, carriage and finally the discharge of dry bulk cargo isn't as easy or straight-forward as people think.
Gearless Bulk Carrier
Many bulk cargoes be dangerous or alter their properties during the transportation. Incorrect loading could cause the ship to be damaged easily. It is possible for the ship to bow when it is not loaded properly. The stress can have life threatening results at sea in rough weather. The remaining cargoes may be impacted by the residuals of other cargoes. Certain bulk cargoes are vulnerable to damage from water. cement power. It is not always easy to verify the exact quantities of cargoes which were loaded or removed. These aspects have significant implications on the operations of bulk cargoes. Discharging bulk cargo using? If conveyor belts and similar systems aren't controlled and supervised, bulk cargoes will create the shape of a cone. The angle created by the cone is known as 'angle of repose'. It varies from one cargo to the next. Cargoes made of iron ore for instance, can create an angle-shaped cone. Cargoes that allow to move around freely will result in the cone with a narrow angle. A cargo that has a low angle of repose has the possibility of shifting during the passage. Certain cargoes may require bulldozers in order to help spread the load over the holdings. Most dry-bulk carriers need to use facilities at shore for loading cargo and discharging. But certain bulk carriers come with self-unloading facilities, such as conveyors below cargo holds or cranes that go up the deck.
