There are numerous risks that can be encountered when operating seagoing bulk carriers. The most important shipboard issues need the use of a careful plan and care. This website is an easy reference for the an international shipping community, offering guidance and details on discharge and loading of different bulk cargoes and to remain within the limitations according to the guidelines of the classification society. It's vital to reduce the likelihood of over-stressing the ship's structure and also following all necessary safety measures for a secure sea crossing. The detail pages on our website cover various bulk carrier related topics which could be beneficial to people working on board and those who working ashore at the terminal.
The general characteristics of bulk seagoing ships
Bulk carriers, or single-deck vessels with top-side tanks, or hopper side tanks within cargo spaces, are made to carry bulk cargo of single commodities. Bulk cargo that is solid can be any substance, apart from gasoline or liquid, that is comprised of a mix of granules as well as particles. They are loaded directly into the vessels cargo space with no sort of containment. Sugar, grain, and ores in bulk are examples of such dry cargo. Bulk carriers can be defined as any ship that is designed to transport liquid or solid bulk cargo. Tankers are also part of. The term bulk carrier is used in normal usage to describe vessels that are built to carry bulk cargos. These include grain or similar agricultural products and minerals such as coal, ore, and stone on one or more of the voyage legs. Have a look at this blog for more.

What Exactly Is A Bulk Carrier What Are The Main Features 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 capacities range 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 40000 tonnes) generally come with cargo handling equipment with larger vessels. Larger vessels use facilities on the shore for loading and unloading
Cargo holds that are big do not have obstructions, and are bigger hatch sizes for ease of loading/unloading.
-Ballast holds are a common feature on bulk carriers. This can be used for ballast voyages to increase stability. For partially ballasting the voyage, two or three additional holds might be allowed, however they are only permitted in port
-They can be covered with single pull or hydraulic, or stacking (piggyback) kind of steel hatch covers
Four types of ballast tanks
Sloping topside wing tanks
Sloping bottom side-wing tanks
Double bottom tanks
After-peak and peak ballast water tank.
Are they bulk cargo that is solid? Any other substance, other than gasoline or liquid comprised of the mixture of smaller pieces, uniform in composition, and loaded directly into cargo areas. Cargoes carried by bulk carriers include "clean" food items as well as "dirty" minerals. They may react to each other as well as with contamination sources such water. This is why it is essential to clean the cargo areas for the specific product. A surveyor will often be called upon to examine the space and determine if it's suitable to be loaded. It is crucial that any leftovers from previous cargo be removed to ensure that no contamination will occur. The bulk cargo is most susceptible to being damaged by water. This means that the holds must be dry in order to allow cargo to enter. Additionally the hatch covers should be waterproof and sealed when required to stop water from entering. All fittings in the hold (ladders and pipes guards, bilge covers and so on.) are to be checked. It is important to inspect the fittings within the hold (ladders and pipe guards, etc.) and ensure that they are installed correctly. The equipment may cause serious damages to conveyor belt systems and, consequently, delays and the ship would be held accountable, should they accidentally discharge the cargo.

Bulk Carrier, Bulker The vessel is designed to carry dry cargo. The bulk carrier of the conventional type has one deck and a single skin. Bulk carriers are designed to transport bulk cargo of any size, heavy or light, and have a maximum load of 450 lbs. It isn't as easy or simple as you imagine.
Gearless Bulk Carrier
Many bulk cargoes be dangerous or alter their properties while in transport. Improper loading can easily result in damage to the ship. There is a possibility for a vessel to bow if not properly loaded. This is called stress? could lead to dangerous consequences on the sea, particularly in severe weather. Other cargoes could also be affected by residuals from previous cargoes. Some bulk cargoes, like cement power, can also suffer from water damage. cement power. It is challenging to confirm the quantities and weights of cargoes unloaded and loaded. All these factors have serious impact on the security of bulk cargoes. Discharging bulk cargo using? If conveyor belts and similar systems aren't controlled and supervised, bulk cargoes will create the shape of a cone. The angle that is created by the cone is referred to as the 'angle of repose'. It is different from cargo to cargo. Iron ore-based cargoes form a steep-angled cone while the cargo that flows freely will make a cone that is shallow. The cargo with an angle that is low to rest is more prone to shifting in transit. For certain cargoes it is possible that bulldozers are required to spread the load into the sides of the holds when the cargo is close to completion. Dry bulk carriers typically have to use facilities at shore for loading cargo and discharging. However, some bulk carriers have self unloading features, such as conveyors below the cargo hold or cranes on deck.
