Seagoing Bulk Carriers: Use and General Use
The operation of seagoing bulk carrier ships was fraught with risks. You should plan well and exercise caution in handling all important shipboard matters. This website serves as an easy reference for the international shipping industry and offers guidance and details on loading and discharging bulk cargo types. These limitations are set by the classification societies. It is crucial to limit the chance of stressing structure of the ship and to follow the safety rules for the safety of sea travel. Our detail pages contain various topics related to bulk carriers which could be beneficial to the crew onboard as well as those working on shore in the terminal.
General features for seagoing bulk carriers
Bulk carriers can be single-deck vessels. They come with top-side tanks, as well as hopper side tanks. These tanks are used in cargo spaces. They are built to carry solid bulk cargo. Solid bulk cargo is any material, that is not gas or liquid comprised of particles, granules or any other large chunk of material that is generally homogenous in composition. It is directly loaded into the space of the ship's cargo compartments without any immediate form of confinement. Examples of dry cargo include sugar, grain and bulk ores. In its broadest sense the term "bulk carrier" embraces all ships designed primarily for the carriage of liquid or solid cargo in bulk form, and so would include tankers. The term"bulk carrier" is commonly used to refer to vessels designed to transport solid bulk cargos. They include grains, similar agricultural products, and minerals such as coal ore and stone , on one or more of the voyage legs. Check out this

What Is A Bulk Carrier? The Following Are The Main Features 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 Capacity ranging from 3,000 tons to 300,000 tonnes
Averaging speed between 12 and 15 knots
-Single deck ships, ie no tweendecks
Carriers with medium to small size bulk (carrying capacity between 40 to 60,000 tonnes) typically have cargo handling gear. However larger vessels may use facilities on shore to load or unload.
The cargo hold is usually big, with no obstructions. They also have bigger hatches to facilitate the easy loading and unloading of cargoes
The bulk carriers typically have one cargo space that is dedicated to ballast. This can be used on ballast voyages in order to increase stability. Additional holds can be allowed for partial ballasting, however only when in port.
They have single pull, hydraulic or stacking (piggy- back) hatch covers made of steel.
Four kinds of ballast tanks :
Sloping topside wing tanks
Bottom side of wing tank sloping
Double bottom tanks
Post peak and peak peak ballast water tanks
Are you searching for bulk bulk material that is solid? Anything that is not liquid or gas, consisting of a combination of particles, granules or any larger pieces of materials, generally of uniform composition and loaded directly into the cargo space without any intermediary form of containment. Cargoes transported by bulk carriers include "clean" food items and "dirty" minerals. These materials can react to each other as well as with contamination sources such water. Thus, it is essential to prepare the cargo space for the specific item being transported. Cleanliness must be appropriate for the item to be loaded. This will usually require a surveyor to pass the space as suitable to load. It is crucial that any remnants of previous cargo be removed to make sure that contamination doesn't occur. The bulk cargo is the most susceptible to damage from water. This implies that the hold need to be dry for cargo to be received. Furthermore the hatch covers should be waterproof and sealed when necessary to prevent water intrusion. All fittings inside the storage area (ladders and pipe guards, bilge cover and bilge cover.) are to be checked. You must inspect each fitting in the hold (ladders,pipe guards,bilge covers...) to ensure that they're in good operating condition. If they're not correctly fitted, these pieces of equipment may cause severe damage to conveyor systems, which could cause delays. Have a look at this

Bulk Carrier, Bulker It is built to transport dry cargo. Bulk carriers that are conventionally constructed with a single deck with a single skin, a double bottom, and hopper side tank. Topside tanks in cargo spaces are also included. Bulk carriers are designed to load the maximum deadweight for bulk cargo of any kind including heavy ore and lighter grain . The loading, carriage and discharge of dry bulk cargo aren't as straightforward or simple as people think.
Carrier for bulk material without equipment
Many bulk cargoes are characterized by dangerous properties, and they can alter their properties after passage. Unsafe loading could cause damage to the vessel. It is possible for a vessel to bow if not properly loaded. This is known as stress? When the weather is rough the stress can result in serious problems at sea. The remaining cargoes may also be affected by residuals from other cargoes. Certain bulk cargoes can suffer water damage. cement power. It is challenging to confirm the quantities and weights of cargoes that are loaded and unloaded. These aspects have significant implications for the operations of bulk cargoes. Discharging bulk cargo using? Bulk cargoes have an inherent tendency to form a cone once they are loaded when conveyor belts or similar systems are not supervised and monitored. The angle that the cone creates is known as the angle, or repose'. It varies for each type of cargo. Cargoes like iron ore can form a steeply angled cone. However, cargoes that flow freely may form a shallow angle cone. Low angles of repose may result in cargo shifting when it is in the course of transport. Bulldozers could be utilized for certain items to spread the load onto the sides of the hold when the cargo is near to its completion. Although most dry bulk carriers utilize shoreside facilities to load cargo or discharge Some bulk carriers provide self-unloading facilities using conveyors underneath the cargo hold or cranes on decks.
