Purpose And General Use Of Seagoing Bulk Carriers
Operation of sea going bulk carriers posed a number of risks. A careful planning process and taking precautions for all shipping-related issues is essential . This site serves as 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 ensure that the structure of the ship is not stressed and all safety precautions are in place in order to ensure safety on the sea. Our detailed pages address a variety of aspects of bulk carriers that may be relevant to those who work onboard or at the terminal.
General characteristics of seagoing bulk vessels
Bulk carriers may be single-deck vessels. They come with top-side tanks as well as side tanks for hoppers. These tanks are utilized for cargo spaces. They are made to transport bulk solid cargo. Solid bulk cargo refers to any other material than gas or liquid, which is smaller pieces of material, usually evenly arranged, and loaded directly into ship's cargo areas. Example of such dry cargo are grain, sugar and ores in bulk. In the broadest sense of the word, the term bulk carrier encompasses all vessels designed to transport liquid or solid cargo in bulk form that is, for example, tankers. The term"bulk carrier" is typically used to describe vessels that are specifically designed to carry bulk solid cargos. This includes grain and other agricultural products and minerals such as coal ore and stone , on some or all of the voyage legs. Click over to this

What Exactly Is Bulk Carrier?
"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 of medium to small size bulk (carrying capacity between 40 and 60,000 tonnes) generally have equipment for handling cargo. However, larger vessels can use shore-based -facilities to load or unload.
The cargo hold is usually big, with no obstructions, and have larger hatch sizes to allow the easy loading and unloading of cargoes
Ballast holds are a standard feature on bulk carriers. It can be utilized on ballast voyages for improved stability. It's also possible to ballast in part, but this is only for ports.
They are covered with single pull or hydraulic or stacking (piggyback) kind of steel hatch covers
Four types of ballast tanks:
Sloping topside wing tanks
Sloping tanks with bottom-side-wings that slope
Double bottom tanks
After-peak and peak ballast water tank.
What is a solid bulk cargo? Anything that isn't liquids or gases, made up of granules or particles or larger pieces of material. These materials can be loaded directly into cargo spaces without any intermediary form of containment. The bulk carriers that transport cargo comprise "clean" foodstuffs as well as "dirty" minerals. They may react to each other as well as with water sources that are contaminant, such as. This is why it is crucial to prepare the cargo space for the particular product. A surveyor will often be required to inspect the space and determine if it is suitable to be loaded. To avoid contamination, it is vital that any residue left behind by a previous cargo be removed. Water is the primary cause of destruction to bulk cargoes. It is vital that the holds are dry in order to allow cargo. Hatch covers must be watertight to prevent water from entering. All fittings in the storage areas (pipe guards and cover for bilge, etc.) must be examined. It is essential to check all fittings in the hold for cargo (ladders and pipe guards, etc.) and ensure they are correctly installed. They could cause damages to conveyor belts, which can result in delays. The ship may be held responsible if they are discharged in error with cargo. Peruse this

Bulk Carrier or Bulker? Bulk Carrier, Bulker A vessel that is able to transport dry cargo. It is not intended to be a bulk liquid carrier or tanker. The conventional bulk carrier is built with one deck, a one skin double bottom, topside tanks, and side tanks that are located in cargo areas. Bulk carriers are built to transport bulk cargo of any size, heavy or light, and have a maximum load of 450 pounds. The procedure of loading, transporting and the release of dry bulk cargo is more complicated than most people think.
Gearless Bulk Carrier
A lot of bulk cargoes pose dangers and could be altered in transit. Incorrect loading can cause damage to the vessel, e.g. loading a forward hold to it max can result in the vessel to bend. This is known as stress? can lead to dangers to life at sea during severe weather. The remaining cargoes may also 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 weights or quantities of cargoes loaded or discharged. These factors can have serious consequences on how bulk cargoes are safely transported. Discharging bulk cargo using? If conveyor belts and similar systems are not controlled and supervised the bulk cargoes create the shape of a cone. The angle that is created by the cone is known as the'angle of repose'. It is different depending on the cargo. Cargoes like iron ore can form a cone that is steeply angled. However, cargoes which flow freely can form a shallow angle cone. The low angles of repose can cause the cargo to shift when it is in transportation. As the cargo nears its completion, bulldozers could have been used to divide the load across holds. Most dry-bulk carriers need to use facilities at shore for cargo loading and discharging. However certain bulk carriers come with self-unloading facilities like conveyors beneath the cargo hold or cranes on the deck.
