Seagoing Bulk Carriers: Purpose and General Use
Many hazards were involved in the operation of sea-going bulk carriers. The safety of sea-going bulk carriers is a matter of meticulous plan. This site offers quick and easy information to the international shipping community on the best way to load and unload bulk cargo. But it is important to not exceed the restrictions that are set by the classification society. It is essential to not stress the structural integrity of the vessel and follow all safety procedures for safe sailing at sea. The details pages of bulk carriers are filled with information that can be beneficial for both the personnel working at the terminal and those working aboard.
The general characteristics of bulk seagoing ships
Bulk carriers are equipped with one deck, and they have top-side tanks as well as the hopper tank. They are able to carry bulk cargo that is a single product. Anything that isn't gas or liquid but is bulk solid cargo, which includes any material consisting of a mixture or granules, or any other substance with an uniform composition. This material can be put directly into the cargo compartment of a ship and does not require containment. Examples of dry cargo are sugar, grains, and bulk ore. In the broadest sense of the word the term "bulk carrier" encompasses all vessels designed to carry solid or liquid cargo in bulk form, and so would include tankers. The term bulk carrier is commonly used to refer to vessels built to carry bulk cargos. They include grains or similar agricultural products and minerals such as coal, ore and stone on one or more of the voyage legs. Check out this

What Is A Bulkship?
"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 1215 knots
-Single deck ships, ie no tweendecks
Carriers with medium to small size bulk (carrying capacities between 40,000 and 60,000 tonnes) generally have cargo handling gear. However larger vessels may use facilities on shore to load or unload.
The cargo holds are typically big, with no obstructions, and have bigger hatches to facilitate the easy loading and unloading of cargoes
The majority of bulk carriers have a ballast hold. This can also be used to increase stability during ballast voyages. One or two more holds may be permissible for partial ballasting in ports, but only
They have hydraulic, single pull or stacking (piggy- back) hatch covers made of steel.
There are four types of ballast tanks or ballast types.
Sloping topside wing tanks
Bottom of wing slopes downwards tanks
Double bottom tanks
The ballast tank is a peak and then a later peak tank.
Is it solid bulk cargo? Any material that is not gas or liquid, made up of a mixture of granules, particles or any larger pieces of materials, generally homogenous in composition and loaded directly into the cargo spaces without any intermediate method of containment. There are a variety of cargoes that are transported by bulk carriers. They carry food as well as minerals that can react with each others as well as in conjunction with water sources. The cargo area needs to be cleaned in a manner that allows loading. Surveyors will often need to inspect the space to make sure it is safe to load. To ensure that contamination does not occur it is essential that any leftovers left by previous cargoes be eliminated. The damage to bulk cargoes is mainly due to water. The holds must be dry to receive cargo. But the hatch covers need to be watertight, or sealed as needed to keep water out. All fittings in the hold (ladders pipes, ladders and bilge covers.) It is crucial to examine all fittings in the hold for cargo (ladders and pipe guards, etc.) and ensure they are properly installed. This equipment can cause serious delay and damage to conveyor belts. Unintentionally discharged cargo could cause the ship to be held responsible. Click over to this

Bulk Carrier or Bulker? Bulk Carrier, Bulker A vessel that is able to carry dry cargo. It's not meant to be a bulk liquid tanker or carrier. A conventional bulk carrier is constructed with a single deck, single skin and double bottom. It also has topside tanks, and side tanks within cargo spaces. Bulk carriers can load any bulk cargo that is light or heavy grain, up to their maximum deadweight. The loading, transportation and discharge of bulk dry cargo aren't as straightforward or simple as people believe.
Gearless Bulk Carrier
Certain bulk cargoes can be dangerous and may be damaged during passage. The ship could be damaged by improper loading e.g. loading a forward hold to it max can cause the ship to break. This could cause the ship to'stress'. When the weather is rough, this can cause dangerous problems on the sea. Remains of previous cargoes may also seriously effect latter cargoes. Certain bulk cargoes could be affected by water damage, e.g. cement power. It is hard to determine the cargoes that are loaded or discharged. These factors have serious implications for the operation of bulk cargoes. Discharging bulk cargo using? bulk cargoes can form a cone if they are loaded onto conveyor belts. The angle of this cone, also known as the "angle for repose", varies with each cargo. Cargoes like iron ore can form a cone that is steeply angled. But, cargoes that flow freely may make a shallow angle cone. A cargo with an angle that is low or repose could shift in the course of. When cargo is nearing the point of completion, bulldozers might need to be employed to distribute the load across holds. Dry-bulk carriers rely on shoreside facilities to load and discharge cargo. Bulk carriers can also self-unload using cranes or conveyors on deck.
