Seagoing Bulk Carrier A General Purpose and Usage
The work of sea-going bulk carrier vessels was rife with risks. Important shipboard issues require cautious planning and prudence. This site is an easy reference for the an international shipping community, offering guidance and details on loading and discharge of various bulk cargo types and is to remain within the limitations according to the guidelines of the classification society. It is essential to reduce the possibility of ship structure being stressed, and to follow all safety standards necessary for safe sea travel. There are detail pages on our website covering a range of subjects related to bulk carriers. They are helpful both for those onboard and those on the shore in the terminal.
General features of seagoing bulk carrier
Bulk carriers can be single deck vessels. They come with top-side tanks, as well as side tanks that hoppers can use. They are typically used in cargo spaces. They are made to carry solid bulk cargo. Solid bulk cargo is anything that is not liquids or gases that is composed of a mixture of granules and particles. It is able to be loaded directly into cargo containers without any kind of confinement. Dry cargoes comprise bulk grain, sugar, and ores. In its broadest sense the term "bulk carrier" embraces all ships designed primarily to transport liquid or solid cargo in bulk form which includes tankers. However, in common usage, bulk carriers are used for vessels designed for transporting bulk goods that are solid. This would include grain and similar agricultural products as well as minerals such as iron, coal ore, stone and coal. Have a look at this

What Exactly Is A Bulk Carrier What Are The Major Characteristics Of Bulk Carriers:
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
-Carrying capacities vary from 3,000 to 300,000.
The average speed is 12-15 knots
-Single deck ships, ie no tweendecks
-small to medium sized bulk carriers (carrying capacity up to 40,000 tonnes) typically have cargo handling gear fitted and larger vessels have shore based -facilities to load and unload cargo.
-Cargo holds that are large have no obstructions and bigger hatch sizes for ease of loading and unloading.
Ballast holds are a standard feature on bulk carriers. It can be used to ballast voyages in order to improve stability. In case of ballasting partially there are two or three additional holds may allow but are only permitted in port
They have single pull and stacking, or hydraulic steel hatch covers.
-Four types and sizes of ballast tank:
Sloping topside wing tanks
Sloping bottom side wings tanks
Double bottom tanks
Peak and afterwards peak ballast tank.
What is a solid bulk cargo? Any material other than gas or liquid, made up of a mixture of particles, granules , or any larger pieces of material, generally homogenous in composition and loaded directly into the cargo spaces without any intermediate method of containment. Bulk carriers are able to carry a variety of cargoes, including "clean" food products and "dirty", minerals, in addition to cargoes that may react one with the other or with other sources of contamination such as water. It is important to ensure that areas for cargo are properly cleaned for each cargo. It is essential to wash the cargo spaces in order to be able to load it. Surveyors are often needed to confirm that the area is clean for loading. To prevent contamination, it is essential to eliminate any residues left by prior cargo. The damage to bulk cargoes can be mainly due to water. The hold must be dry to receive cargo. But, hatch covers must be watertight, or sealed if necessary to keep water out. All fittings in the storage area (ladders, pipe guards and bilge covers.) To ensure they are in good condition and properly installed and properly fitted, all fittings within the hold (ladders and pipe guards and bilge covers.) are to be checked. They could cause damage to conveyor belts and cause delays. The ship may be held accountable if the conveyor belts are accidentally discharged with cargo. Peruse this

Bulk Carrier or Bulker? Bulk Carrier, Bulker A vessel that can transport dry cargo. It's not meant to be a bulk liquid carrier or tanker. A conventional bulk carrier is constructed with one deck, a one skin, double bottom, topside tanks, and side tanks that are located in cargo areas. Bulk carriers are constructed to transport bulk goods of any weight and weight, whether light or heavy and have a maximum load of 450 lbs. The process of loading, transporting and finally the discharge of dry bulk cargo isn't as easy or straight-forward as people imagine.
Gearless Bulk Carrier
Certain bulk cargoes can be dangerous and may be damaged in transit. The ship may be damaged by incorrect loading e.g. loading an forward hold to its maximum could cause the ship to break. This is known as stress? It can result in serious implications for life at sea in difficult weather conditions. The remaining cargoes may also be affected by the residuals of other cargoes. Certain bulk cargoes can be affected by water damage. cement power. It is hard to determine the weights and numbers of cargoes that are loaded and unloaded. These factors have serious implications for the operations of bulk cargoes. Discharging bulk cargo using? bulk cargoes may form a conical shape when they are loaded onto conveyor belts. The angle created by the cone is referred to as the 'angle of repose'. It is different from one cargo to the next. Cargoes made of iron ore, for example, will make an angle-shaped cone. The cargo that is able to move freely will form the cone with a narrow angle. cargoes with lower angles of repose tend to move during transit. Bulldozers might need to be used for some items to distribute the load over the sides of the container because the cargo is close to being completed. Most dry-bulk carriers need to use facilities at shore to load cargo and discharge it. But certain bulk carriers come with self-unloading facilities, such as conveyors below cargo holds or cranes up the deck.
