There are numerous risks that can be encountered when operating seagoing bulk carriers. A careful planning process and taking care for all important shipping-related issues is essential . This site was created to serve as a resource for shipping companies across the globe. It offers information as well as guidance for loading and unloading bulk cargo types. The website must stay within the limitations set by the classification society. It is vital to ensure that the structure of the ship is not stressed and all safety precautions are in place in order to ensure the safety of passage at sea. The detail pages of bulk carriers contain information that can be beneficial to both those working at the terminal as well as those who work aboard.
General characteristics of seagoing bulk ships
Bulk carriers are vessels with a single deck that are fitted with top-side tanks as well as side tanks. They are intended for single-commodity bulk cargo. Solid bulk cargo means any material, other than liquid or gas composed of granules, particles or any larger chunk of material that is generally homogenous in composition. It is loaded directly into cargo areas of ships without any immediate form of confinement. Grain, sugar, and ores in bulk are examples of dry cargo. The broadest definition of the word bulk carrier, all ships that are designed to carry bulk cargo (solid or liquid) in bulk are classified as bulk carriers. Tankers also fall under this category. The term is used primarily for vessels that carry solid bulk cargos. This could include grains and other agricultural commodities. Peruse this url for more.
What Is A Bulk Carrier What Are The General Characteristics Of Bulk Carriers? Are:
"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.
Averaging speed between 12 and 15 knots
-Single deck ships, ie no tweendecks
-small to medium sized bulk carriers (carrying capacities up to 40000 tonnes) typically come with cargo handling equipment with larger vessels. Larger vessels use shore based -facilities to load and unload cargo.
-Cargo holds are often big and clear of obstructions. Large hatch sizes make it easy for loading and unloading.
-Most bulk carriers have one cargo hold dedicated as an ballast hold. It can also be used to increase stability during ballast travels. A couple of additional holds could be permitted for ballasting partial in port, but only
-They can be covered with single pull or hydraulic or stacking (piggyback) type steel hatch covers
-Four types and sizes of ballast tank:
Sloping topside wing tanks
The bottom of the wing is sloping. tanks
Double bottom tanks
Post peak and peak peak ballast water tanks
Is it solid bulk cargo? Anything that isn't liquids and gases that are composed of particles, granules, or bigger pieces of material. They can be placed directly into cargo containers without any intermediate form of containment. It is imperative to make sure that all cargoes are ready for loading, regardless of whether they are "clean" or "dirty", and that there isn't any contamination. It is crucial to clean the cargo space prior to be able to load it. Surveyors are typically required to ensure that the area is clean for loading. To avoid contamination, it is crucial to eliminate any leftovers from a previous cargo. Water is the primary source of damage to bulk cargoes. It is vital that the holds are dry in order to be able to accept cargo. The covers for hatches should be watertight to prevent water from entering. All fittings within the hold (ladders pipe guards, ladders as well as bilge covers.) You must inspect each fitting in the hold (ladders,pipe guards,bilge covers...) to ensure that they are in good operating condition. They may cause serious wear and tear to conveyor belts, which can cause delays. If the equipment is accidentally discharged by cargo, the vessel might be held responsible.

Bulk Carrier, Bulker? A vessel designed to carry dry cargo, loaded onto the vessel, with no container other than that of the ship,s boundaries and is distinct from the liquid bulk carrier or tanker. The conventional bulk carrier is built with a single deck, one skin and double bottom. It also has topside tanks, and side tanks in cargo spaces. Bulk carriers are able to load any type or bulk cargo from light to heavy grain, up to the maximum weight they can carry. It can be difficult to move, load and discharge dry bulk cargo.
Gearless Bulk Carrier
Many bulk cargoes can have dangerous properties or change their properties during the transportation. Improper loading can easily cause damage to the vessel. loading a forward hold to it maximum could result in the vessel to break. This stress could have fatal consequences at sea in rough weather. Remains of previous cargoes may also seriously effect latter cargoes. Certain bulk cargoes may be affected by water damage, e.g. cement power. It is hard to determine the weights and numbers of cargoes unloaded and loaded. These factors all have a serious consequence on the methods of operation for the safe carriage of bulk cargoes. Discharging bulk cargo using? Bulk cargoes are prone to form a cone when they are loaded onto conveyor belts. The angle of this cone, also referred to as the "angle for repose" is different for each cargo. Cargoes such as iron ore will form a steep angled cone, while cargoes which flow freely will form a shallow angled cone. A cargo with a low angle or repose can shift during the course of. Certain cargoes require bulldozers to help spread the load into the holds. Dry-bulk carriers generally use shoreside facilities for cargo loading or discharge Certain bulk carriers have self-unloading options using conveyors under the cargo holds or cranes on deck.
