The General Purpose and Use of Bulk Ships that travel by sea
There are many risks when operating seagoing bulk vessels. It is important to plan ahead and be cautious in dealing with any shipboard issue. This website will offer rapid guidance to the international shipping community and information regarding loading and discharge of various bulk cargo types. It is important to remain within the limits set by the classification organisation. It is essential to reduce the chance of stressing the structure of the ship and to follow all safety precautions for the safety of sea travel. There are a wealth of information on bulk carrier topics in our detail pages, both for those working at sea and those who work ashore.
General characteristics of seagoing bulk carriers
Bulk carriers could be single deck vessels. They are equipped with top-side tanks, as well as side tanks that hoppers can use. These tanks are used in cargo areas. They are made to transport bulk solid cargo. Solid bulk cargo could refer to any kind of material other than gasoline or liquid, that is comprised of a mix of granules as well as particles. They are loaded directly into the space of the ship's cargo areas without any kind of container. Sugar, grain or ores in bulk are examples of such dry cargo. Bulk carriers can be defined as any ship that is designed to carry liquid or solid bulk cargo. Tankers can also be included. However, in normal usage, the term is normally applied to vessels that are designed for the transport of solid bulk cargos, typically grains and other agricultural products minerals such as coal, ore, stone and more., on one or more of the voyages.

What Is A Bulk Vessel?
"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.
-Average speed of 12 15 knots
-Single deck ships, ie no tweendecks
Carriers of small to medium size (carrying up to up to 40,000 tonnes) generally have cargo handling gear. Larger vessels, however, use docks to unload and load.
Cargo holds that are big are free of obstructions and have bigger hatch sizes for ease of loading/unloading.
A single cargo hold is generally designated as a ballast storage. This can be used for ballast voyages to improve stability. In case of ballasting partially the voyage, two or three additional holds may allow but are only permitted in port
They can be used as single-pull or hydraulic covers, or stacking (piggy back) steel hatch covers.
Four types of ballast tanks
Sloping topside wing tanks
Sloping bottom side of wing tanks
Double bottom tanks
Peak and post peak ballast water tanks
Are you searching for solid bulk cargo? Anything other than liquid or gas, consisting of a combination of particles, granules , or any larger pieces of materials, generally homogenous in composition and loaded directly into the cargo spaces without any intermediate form of containment. You must ensure that all cargoes are ready to be loaded, regardless of whether they are "clean" or "dirty", and that there is no contamination. It is important to clean the cargo space prior to load it. Surveyors are typically needed to confirm that the space is ready to be loaded. To avoid contamination, it's important that any residues left from previous cargoes have been removed. Damage to bulk cargoes occurs mainly due to water. The storage areas are required to be dry for the transport of cargo. However, hatch covers must be watertight, or sealed as needed to stop water from entering. All fittings within the holds (pipe guards, bilge covers etc.) must be inspected. It is recommended to inspect each fitting in the hold (ladders,pipe guards,bilge covers...) to make sure that they are in good operating condition. This equipment can cause serious damage and delays to conveyor belt systems. Unintentionally discharged cargo can cause the ship to be held responsible.

Bulk Carrier, Bulker The vessel is designed to transport dry cargo. Bulk carriers that are conventionally constructed using a single-deck with a single skin, a double bottom and side tanks for hoppers. Topside tanks that are located in cargo areas are also available. Bulk carriers are made to hold a maximum deadweight of any type of bulk cargo from heavy ore to lighter grain . The process of loading, transport and discharge of bulk dry cargo isn't as simple or simple as people believe.
Gearless Bulk Carrier
Certain bulk cargoes can be dangerous and may be damaged during passage. Unsafe loading could result in damage to the ship. The ship could bend if it is loaded to the maximum forward holding. This can cause the ship to'stress'. This can lead to life-threatening consequences at sea, particularly in severe weather. Other cargoes could be affected by the residues of previous cargoes. Certain bulk cargoes may be affected by water damage, e.g. cement power. It can be difficult to estimate the weights and quantities of cargoes that are being loaded or unloaded. These variables can have significant implications on the way bulk cargoes are transported safely. Discharging bulk cargo using? conveyor belts and similar systems are not monitored and monitored the bulk cargoes form a cone. The angle created by the cone is referred to as the angle of repose. It differs from one cargo to the next. Iron ore-based cargoes can form a cone that is steeply angled. However, cargoes which flow freely could form a shallow angle cone. Cargoes with a low angle or repose may shift during the course of. Bulldozers may need to be utilized for certain items to distribute the load across the sides of the container as the cargo is close to its completion. While most dry-bulk carriers use shoreside facilities for cargo loading or discharge Some bulk carriers provide self-unloading options using conveyors under the cargo hold or cranes on deck.
