Usage and Purpose Seagoing Bulk Carriers
Many hazards were involved in the operation of sea-going bulk carriers. It is crucial to be careful and cautious in all shipboard matters. This website will offer an immediate guideline to the global shipping community and information regarding loading and discharging various bulk cargo kinds. It is to stay within the limitations set out by the classification agency. It is crucial to minimize the possibility of ship structural stress, and to comply with all necessary safety measures for safe passage at Sea. Our detail pages provide information on a variety of bulk carrier-related subjects that might be of interest to those working aboard or in the terminal.
General features of seagoing bulk carrier
Bulk carriers are single-deck vessels constructed with top-side tanks as well as side tanks for hoppers in cargo spaces . They are designed primarily to carry single-commodity solid bulk cargo. Bulk cargo that is solid refers to any material, other than liquid or gas composed of granules, particles or any other larger piece of materialthat is usually similar in composition. It is directly loaded into the space of the ship's cargo compartments without immediate containment. These dry cargoes can include bulk grains, sugar and ores. In the broadest sense of the word bulk carrier, any ship that are designed to carry bulk cargo (solid or liquid) in bulk would be considered bulk carriers. Tankers are also included under this umbrella. In common usage, however, bulk carriers are used to describe vessels that are designed to carry solid bulk cargos. This includes grain and similar agricultural products as well as minerals like iron, coal, ore, and stone.   Peruse this obo carrier url for more.
What Is A Bulk Vessel?
"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.
The average speed is 12 to 15 knots
-Single deck ships, ie no tweendecks
Small - to medium-sized bulk carriers that carry capacities of up to 40,000 tons are fitted with cargo handling gear. Larger vessels use dock-based facilities for loading and unloading.
Cargo holds that are big do not have obstructions, and are larger hatch sizes for easier loading/unloading.
The bulk carriers typically have one cargo space that is dedicated to ballast. It can be utilized during ballast voyages to improve stability. A couple of additional holds can be allowed to ballast partially, but only when in port.
They can be used for single-pull or hydraulic covers, or stacking (piggy back) steel hatch covers.
Four kinds of ballast tanks :
Sloping topside wing tanks
Bottom of wing slopes downwards tanks
Double bottom tanks
After-peak and peak ballast water tank.
Solid bulk cargo? Any substance, other than liquid or gas, consisting of a combination of particles, granules , or any larger pieces of material generally of uniform composition and loaded straight into the cargo space without any intermediary type of confinement. The cargoes carried by bulk carriers, which range from "clean" foodstuffs to "dirty" minerals and including those that may react with each other or with sources of contamination such as water, mean that care should be taken to ensure that the cargo areas are prepared properly for the particular cargo to be loaded. It is crucial to clean the cargo space prior to be able to load it. Surveyors are usually needed to confirm that the space is ready to be loaded. To avoid contamination, it's essential to get rid of any remnants left from previous cargo. Damage to bulk cargoes is mostly caused by water. Therefore it is not enough that the holdings be dry for cargo to be able to enter, but hatch covers should be watertight, or when necessary closed to stop the ingress of water. All fittings within the storage area (ladders pipe guards, ladders and bilge covers.) It is recommended to inspect each fitting within the hold (ladders,pipe guards,bilge covers...) to make sure that they are in good functioning 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 might be held responsible.

Bulk Carrier, Bulker? A vessel that is designed to transport dry cargo, loaded into the vessel with no containment other than the ship's borders, as distinguished from the bulk carrier that is liquid or tanker. A typical bulk carrier has only a single deck, single skin and double bottom. It also contains topside tanks, hopper side tanks, and cargo space tanks. Bulk carriers are able to load any bulk cargo from heavy to light grain, up to the maximum weight they can carry. It can be challenging to move, load and discharge dry bulk cargo.
Gearless Bulk Carrier
Many bulk cargoes are prone to hazardous properties, or can change their properties on passage. Unintentional loading can cause damage to a vessel. If a ship isn't loaded to its maximum forward could be bent if you load it too high. This is known as stress. could have fatal consequences during rough seas. Other cargoes could be affected by the residues from prior cargoes. Certain bulk cargoes could be affected by water damage, e.g. cement power. It is difficult to verify true quantity or weight of cargoes loaded or discharged. These variables can have significant consequences on how bulk cargoes are safely transported. Discharging bulk cargo using? Bulk cargoes tend to form a cone if they are loaded onto conveyor belts. The angle that is created by the cone is referred to as  the 'angle of repose'. It varies from cargo to cargo. Iron ore cargoes, in contrast have a steeply-angled cone. Cargoes that flow free will form cones that are shallower. Cargoes with a low angle or repose can shift during passage. When cargo is nearing its completion, bulldozers could have to be used to spread the load over a number of holds. Although most dry bulk carriers utilize docks on the shore for cargo loading or discharge, some bulk carriers offer self-unloading facilities using conveyors underneath the cargo holds or cranes in decks.
