Seagoing Bulk Carriers: Use and General Use

The operation of seagoing bulk carrier vessels was rife with risks. Important shipboard issues require cautious planning and prudence. This site provides rapid guidance to the international shipping community as well as information on loading and discharging different bulk cargo types. It is essential to stay within the restrictions set by the classification agency. It is important not to stress the structural integrity of the vessel and to follow all safety guidelines to ensure safe sea passage. Our detail pages cover various bulk carrier-related topics that could be interesting to people working aboard or in the terminal.

General characteristics for bulk ships that travel by sea.
Bulk carriers, or single-deck vessels that have top-side tanks or hopper side tanks in cargo space, are built to transport bulk cargo from a single commodity. Any substance that is not liquid or gas but bulk solid cargo, which includes any material consisting of a mixture or granules, or any other material with an uniform composition. It is able to be loaded directly into the cargo compartment of a ship and doesn't require storage. Dry cargo includes sugar, grain and bulk ore. Bulk carriers are defined as any vessel designed to carry liquid or solid goods in bulk. Tankers are also part of. In normal usage, however the term is usually used to refer to vessels that transport bulk loads of solid goods including grain and other agricultural products and minerals products like coal ore, stone, or even coal on one or several travel legs.

What Is Bulk Carrier?

"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 between 3,000 and 300,000.
Averaging speed of 12-15 knots
-Single deck ships, ie no tweendecks
small to medium sized bulk carriers (carrying capacities up to 40,000 tonnes) generally include cargo handling equipment, while larger vessels use shore based -facilities for loading and unloading
The cargo holds are typically large and free from obstructions. Large hatches allow for simple loading/unloading.
The bulk carriers typically have one cargo space dedicated to ballast. This can be used for ballast voyages to improve stability. One or two more holds could be permitted to ballast in part at ports, but only
-They have hydraulic, single pull or stacking (piggy- back) steel hatch covers
Four types of ballast tanks :
Sloping topside wing tanks
Tanks with a sloping bottom side.
Double bottom tanks
Post peak and peak peak ballast water tanks

What is a solid bulk cargo? Anything other than gas or liquid material made up of a mixture of particles and granules. It is able to be brought directly into cargo areas without any intermediary storage. You must ensure that all cargoes are ready to be loaded, regardless of whether they're "clean" or "dirty", and that there is no contamination. It is important to clean the cargo spaces in order to load it. Surveyors are often needed to confirm that the area is clean for loading. It is vital that the remnants of prior cargo are cleared away to ensure that no contamination will occur. Damage to bulk cargoes is 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 as needed to prevent water ingress. All fittings in the container (ladders pipe guards, ladders and bilge pipes.) must be examined. It is important to inspect all fittings in the hold (ladders and pipe guards, etc.) and ensure they are properly installed. If they are not properly installed, these pieces of equipment may cause severe damage to conveyor systems, which can lead to delays. Have a look at this time charter url for more.



Bulk Carrier and Bulker A vessel that is designed to carry dry cargo. Bulk carriers that are conventional have only a single deck that has a one skin, double-bottom, topside tanks and hopper sides. Bulk carriers can be used to carry heavy ore and lighter grain to their highest weight. The loading, carriage and then the discharge of bulk cargo that is dry isn't as easy or straight-forward as people would imagine.

Gearless Bulk Carrier
Many bulk cargoes may have hazardous properties or may undergo modifications in transport. Incorrect loading could cause damage to the vessel easily. The ship may bend when it is loaded to its highest forward hold. This is called stress? can have life threatening results at sea in rough weather. The residues of earlier cargoes could affect the cargoes that follow. Certain bulk cargoes, such as cement power can also suffer from water damage. cement power. It is difficult to verify the weights and numbers of cargoes that are loaded and unloaded. Each of these aspects have a serious consequence on the operational procedures used for the safe transport of bulk cargoes. Discharging bulk cargo using? Bulk cargoes can be conical when loaded on conveyor belts. The angle that is created by the cone is known as 'angle of repose'. It is different from one cargo to the next. Iron ore cargoes, for example, will form an cone with an angle. Cargoes that allow to move around freely will result in a cone with a shallow angle. cargoes with lower angles of repose are more likely to move during transit. When the cargo is nearing its completion, bulldozers could be required to spread the load across the holds. Dry-bulk carriers rely on the shoreline facilities to discharge and load cargo, but bulk carriers are also able to self-unload with cranes or conveyors that are mounted on deck.
