Seagoing Bulk Carrier: General Use and Purpose

The operation of seagoing bulk carrier ships was fraught with dangers. You must plan your trip well and exercise caution in dealing with any shipboard issue. This site was created to serve as a resource for shipping companies across the globe. It offers information and guidance on loading and unloading bulk cargo types. The site should remain within the limitations that are set by the classification society. It is crucial to minimize the risk of a ship's structure becoming stressed and to follow the safety requirements for safe passage at Sea. There are a wealth of information on bulk carrier topics in our detail pages that are geared towards those working at sea and those who work ashore.

General characteristics of seagoing bulk carriers
Bulk carriers come with one deck, and they have top-side and hopper tanks. They are able to carry bulk cargo, which is a single item. Solid bulk cargo refers to anything other than liquids or gases comprised of a mix of granules and particles. It is able to be loaded directly into cargo containers without the need for any containment. Example of such dry cargo include grains, sugar and ores in bulk. In the broadest sense the term "bulk carrier" embraces all ships designed primarily to transport liquid or solid cargo in bulk form which includes tankers. In common usage, however bulk carriers are utilized for vessels designed for transporting bulk goods that are solid. This is a reference to grain and similar agricultural products and minerals such as iron, coal ore, stone and coal. Have a look at this kamsarmax info for more.

What Is A Bulk Vessel?

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

Carrier Capacity that ranges from 3,000 to 300,000 tonnes
-Average speed of 12 15 knots
-Single deck ships, ie no tweendecks
Carriers from small to medium size (carrying up to 40,000 tonnes) usually include cargo handling equipment. Larger vessels do not, however, have facilities on shore to load and unload.
Cargo holds that are big have no obstructions and larger hatch sizes for easier loading/unloading.
Most bulk carriers have one ballast hold. This is a possibility to use in ballast voyages to increase stability. To partially ballast there are two or three additional holds might be allowed, however they only at port.
They are single pull either stacking or hydraulic steel hatch covers.
Four types of ballast tanks
Sloping topside wing tanks
Sloping tanks with bottom-side-wings that slope
Double bottom tanks
After-peak and peak ballast water tank.

Are you searching for bulk solid cargo? Solid bulk cargo means any material other than gases or liquids comprised of particles, grains, or larger pieces that can be placed directly into the cargo area without the need for additional container. Bulk carriers can carry various cargoes including "clean" food items and "dirty", minerals, in addition to cargoes that may react with one another or other contaminants such as water. It is crucial to ensure that the space is cleaned for each item. A surveyor is often required to look over the area and determine if it's suitable to be loaded. It is vital that the remnants of prior cargo are cleared away to make sure that contamination doesn't occur. The majority of damage to bulk cargo is caused by water. To prevent water ingress hatch covers should be watertight. All fittings inside the storage area (ladders pipe guards, ladders as well as bilge covers.) All fittings within the hold (pipe guards and bilge covers.) should be inspected to make sure they are in proper condition and securely secured. If they are not properly fitted, the equipment can cause significant damage to conveyor systems which could lead to delays. Have a look at this dry cargo ships blog for more.

Bulk Carrier, Bulker A vessel that is designed to transport dry cargo, loaded into the vessel, with no container other than that of the ship,s boundaries in contrast to the liquid bulk carrier or tanker. A traditional bulk carrier is equipped with one deck, a one skin, and a double bottom. It also includes hopper side tanks, topside tanks and cargo space tanks. Bulk carriers can transport any type of bulk cargo including heavy ore and lighter grains, with an maximum weight. The process of loading, transporting and then the discharge of bulk cargo that is dry isn't as straightforward or straight forward as most people think.

Gearless Bulk Carrier
A lot of bulk cargoes have dangerous properties, and they can alter their properties after passage. The ship may be damaged by incorrect loading e.g. The ship may bend when it is loaded to its highest forward hold. This is known as stress? could cause life-threatening consequences during rough seas. Remaining cargoes can be impacted by residues from other cargoes. Some bulk cargoes are susceptible to damage from water. cement power. It can be difficult to establish the exact weights and quantities of cargoes being loaded and not loaded. These elements can have severe implications on the way bulk cargoes are safely transported. Discharging bulk cargo using? Bulk cargoes naturally form circles when loaded on conveyor belts. The angle of the cone, also known as the "angle for repose" is different for each cargo. Iron ore, for instance, are likely to form a steep angled cone, whereas cargoes that flow freely create a shallow angled cone. Cargoes with low angles or repose can shift during the course of. If the cargo is close to its completion, bulldozers could have to be used to spread the load across holds. Dry-bulk carriers generally have to make use of facilities on shore for cargo loading and discharging. However, some bulk carriers have self-unloading facilities including conveyors under cargo holds or cranes that go up deck.
