The Purpose and General Use of Seagoing Bulk Carriers
Numerous hazards existed during the operation of seagoing bulk carriers. The most important shipboard issues need careful planning and caution. This site is a quick reference to international shipping professionals with guidelines and information on the discharge and loading of different bulk cargo types . It is to remain within the limitations that are set by the classification society. It is crucial to limit the chance of stressing ship's structures and comply with all safety guidelines to ensure secure sea passage. Our detail pages cover various aspects of bulk carriers that may be of interest to those working aboard or in the terminal.
General features of bulk seaship vessels
Bulk carriers are single-deck vessels, designed with top-side tanks and hopper side tanks in cargo spaces . They are designed principally to transport one-commodity bulk cargo. Solid bulk cargo is any material, other than liquid or gas composed of granules, particles or any larger piece of material, generally homogenous in composition. It is loaded directly into the cargo spaces of a ship with no immediate confinement. Example of such dry cargo are grain sugar, ores and grains in bulk. Bulk carriers can be described as any ship designed primarily to transport solid or liquid bulk cargo. Tankers are also part of. In ordinary usage, however the term is typically used for those vessels designed to transport solid bulk cargos, typically grains and other agricultural products, and mineral products like stone, coal, ore, etc. in one or more voyage legs.

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"
The capacity of carrying varies from 3,000 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 4000 tonnes) typically have cargo handling equipment. Larger vessels use shore-based -facilities, which allow the loading and unloading of cargo.
-Cargo holds that are large have no obstructions and larger hatch sizes for easier loading/unloading.
Most bulk carriers have a cargo space dedicated to ballast. This can also be used for stability enhancements on ballast travels. A few additional holds may be permitted for partial ballasting but only at port.
They are available in one pull, or stacking (piggyback), type hatch covers made of steel.
There are four kinds and sizes of ballast tanks:
Sloping topside wing tanks
Sloping bottom side wing tank
Double bottom tanks
Post peak and peak peak ballast water tanks
Bulk solid cargo? Any material other than gasoline or liquid comprised of a mixture or granules of smaller pieces that are uniform in composition, and loaded directly into cargo areas. The bulk carriers that transport cargo comprise "clean" foodstuffs as well as "dirty" minerals. They can react with each other and with contaminants like water. This is why it is essential to prepare the cargo space to accommodate the particular item being transported. To load cargo, it is necessary to wash the area thoroughly. A surveyor may be needed to ensure that the space is ready to load. To prevent contamination, it's essential to get rid of any remnants left from previous cargo. The damage to bulk cargoes is mainly due to water. Thus it is essential that not only the holds be dry for cargo to be able to enter, but hatch covers must be watertight, or in the event of necessity, sealed to prevent ingress of water. All fittings in the hold (ladders pipes, ladders as well as bilge covers.) It is essential to check every fitting in the cargo hold (ladders and pipe guards, etc.) and make sure they are correctly installed. They may cause serious damage to conveyor belts, which could lead to delays. If the equipment gets discharged by cargo, the vessel may be held liable. Have a look at this bulkers

Bulk Carrier and Bulker The vessel is designed to transport dry cargo. Conventional bulk carrier is constructed with one deck, a single skin and double bottom. It also has hopper side tanks and topside tanks within cargo spaces. Bulk carriers have the ability to carry heavy ore and light grain at their maximum weight. It can be difficult to transport, load and unload dry bulk cargo.
Gearless Bulk Carrier
A lot of bulk cargoes have dangers and can change their properties upon passage. Incorrect loading can cause damage to the vessel. It is possible for the ship to bow when it is not loaded properly. This could cause the ship to'stress'. can have life threatening results at sea in rough weather. Residues from previous cargoes can also seriously effect latter cargoes. Certain bulk cargoes like cement power, may also be affected by water damage. cement power. It can be difficult to verify the exact quantities of cargoes which were loaded or removed. All of these elements have significant implications for the safety of bulk cargoes. Discharging bulk cargo using? bulk cargoes can form a cone when they are loaded onto conveyor belts. The angle created by the cone is known as the angle of repose. It varies from one cargo to the next. Iron ore-based cargoes form a steep-angled cone while cargoes that flow freely will form a shallow-angled cone. Cargoes with low angles or repose may shift during its passage. Bulldozers may need to be used for some items to distribute the load over the sides of the container because the cargo is close to its completion. Most dry-bulk carriers need to use facilities at shore for cargo loading and discharging. But some bulk carriers feature self-unloading facilities including conveyors under cargo holds or cranes up deck.
