The general purpose and use of Seagoing Bulk Carriers
 
Operation of sea going bulk carriers posed a number of risks. It is essential to be careful and vigilant in all matters pertaining to shipboards. This website is an instant reference for the an international shipping community, offering guidance and details on loading and discharging of various bulk cargoes and to remain within the limitations as specified by the classification society. It is vital to limit the chance of the ship's structure being stressed, and to comply with all necessary safety measures for safe sea travel. There are a wealth of information on bulk carrier topics on our detailed pages, both for those working on the sea as well as those working ashore.
 
General features of seagoing bulk carriers
Bulk carriers, which are single-deck vessels that have top-side tanks, or hopper side tanks within cargo space, are built to carry bulk cargo of single commodities. Solid bulk cargo is any material other that liquid or gas consisting of a combination or larger pieces of material, generally uniformly composed, and loaded directly into ship's cargo space. Examples of dry cargo are grain sugar, ores and grains in bulk. In the broadest sense of the word bulk carrier, all ships designed to transport bulk goods (solid or liquid) in bulk would be classified as bulk carriers. Tankers are also included under the same umbrella. However, in common usage, bulk carriers are used to describe vessels that are designed to carry bulk solid cargos. This includes grain and similar agricultural products as well as minerals like coal, iron, ore, and stone.   Click over to this time charter info for more.
 
 
 
What Is A Bulk-Carrier  What Are The General Characteristics Of Bulk Carriers? Include:
 
"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"
 
Carrying capacity ranges from 3,000 tonnes to 300,000 tonnes
Average speed of 12 to 15 knots
-Single deck ships, ie no tweendecks
Carriers of small to medium size (carrying up to 40 000 tonnes) generally use cargo handling equipment. Larger vessels are, however, equipped with shore-based facilities to load and unload.
The cargo hold is usually spacious, and free of obstructions, and have large hatch sizes that allow for easy loading/unloading of cargoes
Ballast holds are a standard feature on bulk carriers. This is a possibility to use on ballast voyages in order to improve stability. To partially ballast there are two or three additional holds may allow but are only permitted in port
They can be covered by single pull, hydraulic, or stacking (piggyback) style steel hatch covers
-Four types or ballast tanks
Sloping topside wing tanks
Bottom side of wings that are sloping
Double bottom tanks
Ballast for peak and after peak water tank.
 
Are they bulk cargo that is solid? Any substance, other than gas or liquid, made up of a mix of particles, granules or any larger pieces of material, generally homogenous in composition and loaded straight into the cargo spaces without any intermediate method of containment. The goods transported by bulk carriers, ranging from "clean" food items up to "dirty" minerals and encompassing those that could react with each other or with other sources of contamination, like water, suggest that care should be taken to ensure that the cargo areas are prepared properly for the particular cargo to be loaded. For loading cargo, it is necessary to wash the area thoroughly. A surveyor might be required to ensure that the space is ready for loading. To avoid contamination, it's important that all residues from previous cargoes are removed. The damage to bulk cargoes can be due to water. Thus, not only must the holdings be dry to receive cargo but hatch covers should be watertight, or if necessary sealed to prevent the entry of water. All fittings within the storage area (ladders pipe guards, ladders, bilge covers, etc.) It is important to inspect all fittings in the hold (ladders and pipe guards, etc.) and ensure they are installed correctly. If they are not properly fitted, these pieces of equipment could cause serious damage to conveyor systems which could lead to delays. Click over to this dry bulk vessels site for more.
 
 
 
Bulk Carrier or Bulker? Bulk Carrier, Bulker A vessel that can carry dry cargo. It is not intended to be a liquid bulk carrier or tanker. A traditional bulk carrier is equipped with only a single deck, single skin and double bottom. It also has hopper side tanks, topside tanks as well as cargo space tanks. Bulk carriers are designed to carry bulk goods of any size either light or heavy, and have a maximum load of 450 pounds. It isn't as easy or straightforward as you might think.
 
Gearless Bulk Carrier
Many bulk cargoes are prone to hazardous propertiesor change their properties upon passage. Uncorrect loading can cause the ship to be damaged easily. The ship may bend when it is loaded to its highest forward hold. This can cause the vessel to stress. can have life threatening results when the weather is rough at sea. Other cargoes may also be affected by residues from prior cargoes. Certain bulk cargoes could be affected by water damage. cement power. It is not always easy to confirm the exact weight of the cargoes that have been loaded or removed. These variables can have significant implications on the way bulk cargoes are transported safely. Discharging bulk cargo using? bulk cargoes are prone to having an inherent tendency to form a cone whenever they are loaded, if conveyor belts or similar systems aren't closely monitored and controlled. The angle of this cone, which is also known as the "angle for repose" differs with every cargo. Iron ore-based cargoes form a steep-angled cone while cargoes that flow freely will create a cone with a shallow angle. A cargo that has a low angle or repose may shift during passage. Some cargoes will require bulldozers to help spread the load into the holds. Although most dry bulk carriers utilize shoreside facilities to load cargo or discharge, some bulk carriers offer self-unloading options using conveyors under the cargo holds or cranes in decks.
