The General Purpose and Use of Bulk Ships that travel by sea
The operation of seagoing bulk carrier ships was fraught with risks. It is important to plan carefully and exercise care for all important issues on the ship's deck are essential . This site is designed to serve as a resource for shipping companies across the globe. It offers information and guidance on loading and unloading bulk cargo types. The site must remain within the guidelines set by the classification society. It is essential to not stress the ship's structural integrity and to follow all safety guidelines for safe sailing at sea. We have detail pages that cover various topics concerning bulk carriers. They are helpful both for those onboard and those who are ashore in the terminal.
General features for seagoing bulk carriers
Bulk carriers are equipped with only one deck and comprise top-side tanks as well as the hopper tank. They can carry bulk cargo, which is a single item. Solid bulk cargo includes anything other than liquids or gases that is composed of a mixture of particles and granules. It is able to be loaded directly into cargo areas without any kind of containerization. Examples of dry cargo include grains, sugar and ores in bulk. Bulk carriers can be defined as any vessel designed to carry liquid or solid cargo in bulk. Tankers can also be included. The term bulk carrier is typically used to describe vessels that are built to carry bulk cargos. These include grain or similar agricultural products and minerals like coal, ore and stone , on one or more of the voyage legs. Have a look at this

What Is A Bulk Ship?
"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.
The average speed is 12-15 knots
-Single deck ships, ie no tweendecks
Small - to medium-sized bulk carriers with a carrying capacity of up to 40,000 tonnes are equipped with equipment for handling cargo. Larger vessels use dock-based facilities to load and unloading.
-The cargo holds are usually large, without any obstructions, with larger hatch sizes to allow easy loading/unloading of cargoes
Ballast holds are a standard feature on bulk carriers. This is a possibility to use on ballast voyages for improved stability. One or two more holds may be permissible for partial ballasting in port, but only for a limited time.
They have hydraulic, single pull or stacking (piggy- back) type steel hatch covers
Four types and sizes of ballast tank:
Sloping topside wing tanks
Tanks with a sloping bottom side.
Double bottom tanks
Peak and after peak ballast water tank.
Bulk solid cargo? Anything other than gas or liquid material made up of a mixture of particles and granules. It can be brought directly into cargo areas without any intermediary storage. Cargoes carried by bulk carriers comprise "clean" foodstuffs and "dirty" minerals. These materials can react one another and with contaminants like water. Therefore, it is vital to clean the cargo areas for the particular product. It is crucial to clean the cargo spaces in order to be able to load it. Surveyors are often required to verify that the area is clean to be loaded. To avoid contamination it is essential that any residues left behind from a previous cargo are taken away. Damage to bulk cargo is usually caused by water. To avoid water intrusion hatch covers should be watertight. All fittings (ladders or pipe guards as well as bilge covers) inside the container should be examined. All fittings in the hold (pipe guards and bilge covers.) must be checked to ensure they are in proper condition and securely fixed. They could be a cause of damages to conveyor belts, which can create delays. The ship may be held responsible if these items were discharged accidentally with cargo. Click over to this

Bulk Carrier, Bulker This vessel is intended to transport dry cargo. Conventional bulk carriers are constructed with a single deck and a single skin. They also have a double bottom and hopper side tank. Topside tanks in cargo spaces are also available. Bulk carriers are designed to carry the maximum deadweight for bulk cargo of any kind including heavy ore and lighter grain . The process of loading, transport and discharge of bulk dry cargo isn't as simple or as simple as most people believe.
Gearless Bulk Carrier
A lot of bulk cargoes pose dangers and may be damaged during passage. Improper loading could cause damage to the ship, e.g. loading an forward hold to its max can result in the vessel to break. This is called stress? could result in life-threatening consequences at sea, especially in bad weather. The remaining cargoes may be affected by residues from other cargoes. Certain bulk cargoes could be affected by water damage, e.g. cement power. It is not always easy to determine the weights of cargoes that have been loaded or removed. These aspects have significant implications on the operations of bulk cargoes. Discharging bulk cargo using? Bulk cargoes can create a cone when loaded on conveyor belts. The angle of repose is known as "angle of repose" and is different based on each cargo. Iron ore cargoes, for example, will make an cone with an angle. Cargoes that are free to move around freely will result in an angle-shaped cone that has a low angle. Cargoes that have low angles of repose tend to move in transit. As the cargo nears its completion, bulldozers could have been used to divide the load over a number of holds. Dry-bulk carriers generally have to utilize facilities at the shore to load cargo and discharge it. But, some bulk carriers have self unloading features like conveyors beneath cargo holds or cranes that go up the deck.
