Seagoing Bulk Carriers: Use and General Use

Operation of sea-going bulk carriers involved numerous hazards. You should plan well and take care when dealing with any shipboard issue. This site is a quick reference to international shipping professionals with guidelines as well as information regarding the discharge and loading of different bulk cargoes and to be within the restrictions as specified by the classification society. It's important to avoid stressing the structural integrity of the ship and follow all safety procedures to ensure safe sea passage. There are detail pages on our website that cover various topics concerning bulk carriers. These are useful both for passengers onboard as well as those who are ashore in the terminal.

General characteristics of seagoing bulk carriers
Bulk carriers are single-deck vessels constructed with top-side tanks as well as side tanks for hoppers in cargo spaces . They are designed mostly to transport single-commodity bulk cargo. Solid bulk cargo is any kind of material other than liquid or gas, consisting of a combination of granules, particles, or any other larger piece of material, generally uniform in composition, which is directly loaded into the cargo areas of ships without immediate containerization. Grain, sugar, and ores in bulk are some examples of dry cargo. Bulk carrier, as it is understood in its broadest meaning can refer to any vessel specifically designed for carrying bulk cargo, including liquid cargo, or solid cargo. Tankers could also be included. In ordinary usage, however the term is typically used to describe vessels built to carry bulk solid cargos, usually grain and similar agricultural products as well as mineral products such as stone, coal, ore, etc., on one or more voyage legs.

What Is A Bulk Carrier What Are The Major Characteristics Of Bulk Carriers:

"A ship which is intended primarily to carry dry cargo in bulk, including such types as ore carriers and combination carriers"

Carrying capacity between 3,000 and 300,000.
-Average speed of 12 15 knots
-Single deck ships, ie no tweendecks
Carriers of medium to small size bulk (carrying capacity between 40 to 60,000 tonnes) generally have equipment for handling cargo. However larger vessels can make use of shore-based -facilities to load or unload.
The cargo holds are typically large, without any obstructions. They also have larger hatch sizes to allow ease of loading and unloading cargoes
Most bulk carriers have a cargo hold dedicated as a ballast hold. It can be used to increase stability during ballast voyages. A couple of additional holds may be permissible for partial ballasting in ports, but only
They can be used as single-pull, hydraulic or stacking (piggy back) steel hatch covers.
There are four types and sizes of ballast tank:
Sloping topside wing tanks
Sloping bottom side wing tanks
Double bottom tanks
Peak and post peak ballast water tanks

What is a solid bulk cargo? Any other substance, other than liquid or gasoline comprised of the mixture of smaller pieces, uniform in composition, and loaded directly into cargo spaces. Cargoes transported by bulk carriers comprise "clean" foodstuffs and "dirty" minerals. They may react one another and with contamination sources such water. Thus, it is vital to prepare the cargo spaces for the specific cargo. It is essential to wash the cargo areas prior to being able to be able to load it. Surveyors are usually needed to confirm that the space is prepared to be loaded. To avoid contamination, it's important that any residues left from previous cargoes are removed. Bulk cargo damage is mostly caused by water. To prevent water ingress hatch covers should be watertight. All fittings inside the container (ladders pipe guards, ladders as well as bilge.) are to be examined. must be inspected to ensure that they're in good condition and are securely installed. This equipment may cause serious damages and delay to conveyor belts. A mistaken discharge of cargo will result in the ship being found to be responsible.

Bulk Carrier and Bulker It is built for transporting dry cargo. Conventional bulk carrier is constructed with a single deck, single skin double bottom, hopper side tanks and topside tanks in cargo spaces. Bulk carriers can transport any type of bulk cargo including heavy ore and lighter grains, with a maximum weight. The procedure of loading, transporting and the release of dry bulk cargo can be more complex than many people imagine.

Gearless Bulk Carrier
A lot of bulk cargoes may contain dangerous substances or change their properties in transit. Unintentional loading can result in damage to a ship. A vessel that isn't fully loaded can be bent by loading it too high. This is known as stress? can lead to life-threatening situations at sea when there is severe weather. Other cargoes can also be affected by residues of previous cargoes. Certain bulk cargoes could be affected by water damage, e.g. cement power. It is challenging to confirm the amount of cement used and the weight of cargoes unloaded and loaded. These factors can have severe impact on the security of bulk cargoes. Discharging bulk cargo using? conveyor belts and similar systems aren't controlled and supervised, bulk cargoes will form an elongated cone. The angle of the cone, also referred to as the "angle for repose" is different for each cargo. Iron ore cargoes can create a cone with a steep angle, whereas the cargo that flows freely will make a cone that is shallow. A cargo with a low angle to repose is more susceptible to shifting in transit. Certain cargoes may require bulldozers in order to help distribute the load across the holds. Most dry-bulk carriers depend on facilities on the shore for cargo loading and discharge, but certain bulk carriers come with self-unloading capabilities with conveyors underneath the cargo holds or cranes on the deck.
