The general purpose and functions of seagoing bulk carriers
Many risks were present during the operation of seagoing bulk carriers. Careful planning and exercising due precautions for all shipboard matters are important . This site was created to serve as a guide for shipping organizations around the world. It provides information as well as guidance for loading and unloading bulk cargo types. The site should remain within the limits that are set by the classification society. It's important to avoid stressing the structural integrity of the vessel and to follow all safety guidelines for safe passage at sea. Our detail pages contain various bulk carrier-related topics that could be helpful to people working on board and those who working ashore in the terminal.
General features for bulk ships that travel by sea.
Bulk carriers are single-deck vessels that are equipped with top-side tanks and side tanks. They are designed to handle bulk cargo that is a single commodity. Solid bulk cargo is any material other that gas or liquid that is smaller pieces of material, generally evenly arranged, and loaded directly into ships' cargo space. These dry cargoes include bulk grains, sugar and ore. The bulk carrier is a vessel that is primarily used to carry bulky or liquid cargo. This would also include tankers. However, in normal usage, the term is generally used to refer to vessels that transport bulk loads of solid goods including grains and other agricultural commodities in addition to mineral products such coal, ore, or stone in one or more travel legs.

What Is A Bulk Transportation?
"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
The average speed is 12 to 15 knots
-Single deck ships, ie no tweendecks
Small to medium-sized bulk carriers that can carry up to 40,000 tons are fitted with cargo handling equipment. Larger vessels have docks for loading and unloading.
The cargo hold is usually large, without any obstructions, with large hatch sizes that allow for ease of loading and unloading cargoes
A single cargo hold is generally designated as a ballast storage. It can also be used to increase stability during ballast journeys. One or two further holds can be allowed to partially ballast, however only at port.
They have hydraulic, single pull or stacking (piggy- back) type steel hatch covers
-Four kinds and sizes of ballast tank:
Sloping topside wing tanks
Bottom side of wing tanks that are sloping
Double bottom tanks
Peak and after peak ballast water tank.
What is a solid bulk cargo? Anything other than gasoline or liquid, that is composed of a mixture or granules of smaller pieces that are uniform in composition and loaded directly into cargo spaces. You must ensure that all cargoes are ready for loading, regardless of whether they're "clean" or "dirty", and that there is no contamination. To load the cargo, it is important to thoroughly clean the area. A surveyor might be required to mark the area as ready to load. To avoid contamination, it's essential that all traces of previous cargoes are removed. The damage to bulk cargoes occurs mainly due to water. The storage areas are required to be dry for the transport of cargo. But hatch covers should be watertight, or sealed if needed, to keep water out. Every fitting (ladders or pipe guards, as well as bilge covers) in the hold should be checked. You must inspect each fitting inside the hold (ladders,pipe guards, bilge covers...) to ensure that they're in good working order. They can cause significant wear and tear to conveyor belts, which could lead to delays. If the equipment is discharged accidentally with cargo, the ship might be held accountable. Click over to this

Bulk Carrier, Bulker A vessel designed to carry dry cargo. The traditional bulk carrier has a single deck and single skin. Bulk carriers can be used to carry heavy ore and light grain at their maximum weight. The loading, carriage and discharge of bulk dry cargo aren't as straightforward or simple as people think.
Carrier for bulk material without gear
Many bulk cargoes are hazardous and may be damaged throughout the journey. The ship could be damaged by improper loading e.g. loading a forward hold to it maximum can result in the vessel to be bent. This can cause the ship to stress. When the weather is rough, this can cause serious problems at sea. Also, residues from earlier cargoes could have a serious impact on the future cargoes. Some bulk cargoes are also vulnerable to damage from water. cement power. It can be challenging to estimate the weights and quantities of cargoes that are being loaded or unloaded. These factors have serious implications on the operations of bulk cargoes. Discharging bulk cargo using? Bulk cargoes naturally form the shape of a circle when they are loaded onto conveyor belts. The angle of repose is known as "angle of repose" and is different based on each cargo. For iron ore, cargoes will form a steep angled cone, whereas cargoes that flow freely will form a shallow angled cone. Low angles of repose can cause cargo to shift during transit. As cargo nears completion, bulldozers might be necessary to spread the load in the storage areas. Dry-bulk carriers rely on shoreside facilities for loading and discharging cargo, however bulk carriers can also self-unload using cranes or conveyors on deck.
