General purpose and uses of sea-going bulk carriers

Many hazards were involved in the operation of seagoing bulk carriers. It is crucial to plan carefully and be cautious in all shipboard matters. This site is an easy reference for the international shipping industry and gives guidance and advice on loading and discharge of bulk cargo types. These limitations are set by the classification societies. It is essential to not stress the structural integrity of the ship and to follow all safety guidelines to ensure safe sea passage. There are detail pages on our website covering a range of subjects concerning bulk carriers. They are helpful both for passengers onboard as well as those ashore at the terminal.

General characteristics for bulk ships that travel by sea.
Bulk carriers come with a single deck and include top-side and the hopper tank. They are able to carry bulk cargo, which is a single item. Solid bulk cargo refers to any substance other than liquid or gas consisting of larger pieces of material, generally evenly arranged, and loaded directly into ship's cargo space. Examples of dry cargo include sugar, grain and bulk ores. Bulk carrier, when understood in its broadest sense can refer to any vessel specifically designed to carry bulk cargo such as liquid cargo or solid cargo. Tankers would also be included. In common usage, however, bulk carriers are used to transport solid bulk cargos. This would include grain and similar agricultural products as well as minerals like iron, coal ore, stone, and coal. Check out this dry bulkers info for more.


What Is A Bulk-Carrier The Main Characteristics Of Bulk Carriers Include:

"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"

Carrying capacity ranges from 3,000 tonnes to 300,000 tonnes
Average speed of 12 15 knots
-Single deck ships, ie no tweendecks
Small to medium size bulk (carrying capacities between 40,000 and 60,000 tonnes) generally have equipment for handling cargo. However larger vessels can make use of docks to load and unload.
The cargo hold is usually spacious, and free of obstructions, with larger hatch sizes to allow ease of loading and unloading cargoes
Ballast holds are a standard element on bulk carriers. It can be used to ballast voyages to improve stability. Some additional holds could be allowed for partial ballasting, but only in port
They can be used as single-pull, hydraulic or stacking (piggy back) steel hatch covers.
Four kinds of ballast tanks :
Sloping topside wing tanks
Sloping tanks with bottom-side-wings that slope
Double bottom tanks
Ballasts for peak and post peak water tanks

Solid bulk cargo? Solid bulk cargo means anything that is not gas or liquids that is made up of grains, particles, or larger pieces that can be loaded directly into the cargo area without the need for additional container. The cargoes carried by bulk carriers, ranging from "clean" foodstuffs to "dirty" minerals and encompassing the ones that react with each other or with sources of contamination like water, suggest that care should be taken to ensure that the spaces are properly prepared for the specific cargo that is to be loaded. For loading cargo, it is essential to thoroughly clean the area. A surveyor may be needed to mark the area as ready for loading. To avoid contamination, it's essential to eliminate any residues left by prior cargo. The bulk cargo is the most vulnerable to water damage. This means that the storage areas must be dry in order for cargo to be received. Furthermore hatch covers need to be waterproof and sealed when needed to prevent water ingress. All fittings within the hold (pipe guards, the bilge covers, etc.) must be checked. It is recommended to inspect each fitting inside the hold (ladders,pipe guards, bilge covers...) to ensure that they're in good operating condition. The equipment could cause damage to conveyor belts and result in delays. The ship could be held responsible if they are accidentally discharged with cargo. Check out this dry cargo blog for more.


Bulk Carrier or Bulker? The vessel is designed to transport dry cargo. Traditional bulk carriers are built with a single deck with a single skin, a double bottom, and hopper side tank. Topside tanks that are located in cargo areas are also included. Bulk carriers have the ability to transport heavy ore as well as light grain with their greatest weight. It isn't easy to load, transport and disperse dry bulk cargo.

Gearless Bulk Carrier
Many bulk cargoes have dangerous properties or change their properties during transport. The ship could be damaged by incorrect loading e.g. loading the forward hold to its max can result in the vessel to bend. This is called stress? It can result in dangers to life at sea, when there is extreme weather. Remaining cargoes can be affected by the residuals of other cargoes. Some bulk cargoes can also be affected by water damage, e.g. cement power. It is not easy to establish the exact the weights or amounts of cargoes loaded or discharged. Each of these aspects can have an impact on the procedures for the safe transport of bulk cargoes. Discharging bulk cargo using? The bulk cargoes naturally form into a circle when loaded onto conveyor belts. This angle is called the "angle of repose" and is different based on the particular cargo. Iron ore cargoes, in contrast have a steeply-angled cone. Cargoes whose flow is free will form cones that are shallower. Low angles of repose could cause the cargo to shift when it is in transit. As cargo nears completion, bulldozers might be required to distribute the load within the holds. Dry bulk carriers typically have to use facilities at shore for cargo loading and discharging. However certain bulk carriers come with self unloading features, such as conveyors below cargo holds or cranes that go up deck.
