|Purpose And General Use Of Seagoing Bulk Carriers
There are numerous risks that can be encountered during the operation of seagoing bulk carriers. The safety of seagoing bulk carriers is the subject of careful planning. This website is an instant reference for the international shipping community with guidance and details on loading and discharge of various bulk cargoes and to stay within the limits as specified by the classification society. It's vital to reduce the chance of stressing too much on the structure of the ship and following all necessary safety measures for a safe sea voyage. The details pages of bulk carriers are filled with information that can be beneficial to both those working at the terminal as well as the crew members working onboard.
The general characteristics of bulk ships that travel by sea.
Bulk carriers are single-deck vessels that are equipped with top-side tanks as well as side tanks. They are intended for single-commodity bulk cargo. Bulk cargo that is solid refers to any kind of material other than liquid or gas comprised of granules, particles or any larger chunk of material that is generally uniform in composition, which is directly loaded into the cargo spaces of a ship without any immediate form of containment. Examples of dry cargo are sugar, grain and bulk ore. In the broadest sense, the term bulk carrier embraces all ships designed primarily to carry solid or liquid cargo in bulk form which includes tankers. The term is typically used to describe ships that carry bulk goods that are solid. This includes grains as well as other agricultural products. Have a look at this panamax bulk carrier site for more.
What Is A Bulk-Carrier ?General Features 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"
The capacity of carrying varies from 3,000 to 300,000.
Average speed of 12 to 15 knots
-Single deck ships, ie no tweendecks
Small to medium-sized bulk transporters that can carry up to 40,000 tons are fitted with equipment for handling cargo. Larger vessels make use of docks for loading and unloading.
The dimensions of cargo hold are typically big without obstructions. They also have larger hatch sizes which allow for easy loading/unloading.
A single cargo hold is generally classified as an ballast storage. This is a great way to increase stability during ballast voyages. It's also possible to ballast in part, but this is only for port.
They have single pull, hydraulic or stacking (piggy- back) hatch covers made of steel.
Four kinds of ballast tanks :
Sloping topside wing tanks
Sloping bottom side wing tank
Double bottom tanks
Peak and after-peak ballast water tank.
Bulk solid cargo? Anything other than liquid or gas material made up of a mixture of particles and granules. It can be loaded directly into areas of cargo without the need for intermediate containment. You must make sure that all cargoes are ready to be loaded, regardless of whether they're "clean" or "dirty", and that there isn't any contamination. The cargo space must be cleaned in a manner that allows for loading. Surveyors are often required examine the area to make sure it is safe to load. To avoid contamination, it's essential to eliminate any remnants left from an earlier cargo. Damage to bulk cargoes occurs mainly due to water. The holds should be dry in order to accommodate cargo. But hatch covers should be watertight, or sealed if necessary to keep water out. All fittings inside the storage area (ladders pipe guards, ladders, bilge, etc.) must be examined. must be inspected to ensure that they're in good shape and securely fitted. The equipment may cause significant damage to conveyor belts and consequent delays, for which the ship will be held responsible if they happen to discharge inadvertently with the cargo.

Bulk Carrier, Bulker A vessel made to carry dry cargo that is loaded into the vessel, with no container beyond the ship,s boundaries and is distinct from the bulk carrier that is liquid or tanker. A conventional bulk carrier is constructed with one deck, a one skin double bottom, topside tanks, and side tanks in cargo spaces. Bulk carriers are able to carry all kinds of bulk cargo including heavy ore and light grains up to an maximum weight. The procedure of loading, transporting and then releasing dry bulk cargo is more difficult than people believe.
Carrier for bulk materials without gear
Many bulk cargoes have hazardous propertiesor change their properties upon passage. The ship can be easily damaged by improper loading e.g. There is a possibility for a vessel to bow if it is not properly loaded. This is known as stress. When the weather is rough it can lead to life-threatening problems at sea. Last cargoes could be negatively impacted by the residues of earlier cargoes. Some bulk cargoes are vulnerable to damage from water. cement power. It's not always simple to verify the exact weight of the cargoes that were loaded or removed. These variables can have significant implications on the way bulk cargoes are safely transported. Discharging bulk cargo using? If conveyor belts and similar systems are not controlled and supervised the bulk cargoes create a cone. This angle is known as the "angle of repose" and it varies depending on the specific cargo. Cargoes made of iron ore for instance, will create an cone with an angle. Cargoes that allow to flow freely will create a cone with a shallow angle. A cargo with a low angle or repose can shift during passage. For some cargoes it is possible that bulldozers are needed to spread the load into the sides of the holdings when the cargo is close to completion. Dry-bulk carriers generally use shoreside facilities for cargo loading or discharge, some bulk carriers offer self-unloading capabilities with conveyors beneath the cargo holds or cranes on decks.
