Useful Bulk Ship Tips

The Purpose and General Use of Seagoing Bulk Carriers

Numerous risks were encountered during the operation of seagoing bulk carriers. A careful planning process and taking care for all important shipping-related issues is essential . This website is intended to serve as a reference for international shipping communities. It offers information and guidelines for loading and unloading bulk cargo types. The site should remain within the limits established by the classification society. It is vital to limit the possibility of ship structure being stressed, and to comply with all necessary safety measures for safe passage at Sea. Our detail pages contain various topics related to bulk carriers which could be beneficial to the crew onboard as well as those working on shore at the terminal.

The general characteristics of bulk seagoing vessels
Bulk carriers, which are single-deck vessels with top-side tanks or hopper side tanks in cargo space, are built to transport bulk cargo from a single commodity. Solid bulk cargo means any material, other than gas or liquid comprised of granules, particles, or any other larger chunk of material that is generally similar in composition. It is loaded directly into space of the ship's cargo compartments without any immediate form of containment. Example of such dry cargo include grains, sugar and ores in bulk. In the broadest sense the term "bulk carrier" includes all vessels that are designed to carry liquid or solid cargo in bulk form that is, for example, tankers. However, in common usage, bulk carriers are used for vessels designed for transporting bulk solid cargos. This is a reference to grain and similar agricultural products and minerals like iron, coal, ore, and stone. Click over to this bulk carrier ship specialist for more.


What Is Bulk Carrier?

"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.
Average speed of 12 to 15 knots
-Single deck ships, ie no tweendecks
Carriers of small to medium size (carrying up to up to 40,000 tonnes) typically have cargo handling gear. Larger vessels are, however, equipped with shore-based facilities to load and unload.
The dimensions of cargo hold are typically vast with no obstructions. They also have larger hatch sizes which enable easy loading and unloading.
The bulk carriers typically have one cargo hold designated for the ballast storage. It can be utilized during ballast voyages to improve stability. In case of ballasting partially, one or two additional holds could be permitted, but are only permitted in port
They are available as one pull, or stacking (piggyback) and type hatch covers made of steel.
Four types of ballast tanks
Sloping topside wing tanks
Tanks with a sloping bottom
Double bottom tanks
Peak and after peak water tank.

Bulk solid cargo? Any material, other than gas or liquid, made up of a mixture of granules, particles or any larger pieces of material generally homogenous in composition and loaded straight into the cargo containers without any intermediary method of containment. There are many cargoes being carried by bulk transporters. They include food and minerals that can react with each others or with water sources. Cleaning should be sufficient to allow the cargo to be loaded. This will usually require a surveyor to assess the space to ensure it is suitable to load. To ensure that contamination does not occur it is essential that any leftovers left by previous cargoes be removed. Damage to bulk cargoes is mostly due to water. The hold must be dry to receive cargo. But the hatch covers need to be watertight, or sealed if needed, to keep water out. Every fitting (ladders or pipe guards as well bilge covers) within the hold must be checked. It is crucial to examine every fitting in the hold (ladders and pipe guards etc.) and ensure they are correctly installed. If they are not properly fitted, these pieces of equipment may cause severe damages to conveyor systems which could lead to delays. Check out this voyage charter info for more.


Bulk Carrier, Bulker? Bulk Carrier, Bulker A vessel that can carry dry cargo. It's not designed to be a bulk liquid tanker or carrier. Conventional bulk carriers are constructed with a single-deck and a single skin. They also have a double bottom and hopper side tank. Topside tanks in cargo spaces are also included. Bulk carriers are designed to load the maximum deadweight for any bulk cargo including heavy ore and lighter grain . It isn't as easy or simple as you imagine.

Gearless Bulk Carrier
Many bulk cargoes be dangerous or alter their properties while in the transportation. Improper loading could cause damage to the ship, e.g. There is a possibility for a vessel to bow when it is not properly loaded. This is called stress. This can lead to dangerous consequences on the sea, especially in bad weather. In addition, leftovers from prior cargoes may have a serious impact on the future cargoes. Water damage can also have a devastating effect on some bulk goods e.g. cement power. It is hard to determine the weights and numbers of cargoes unloaded and loaded. All of these elements have significant implications for the safety of bulk cargoes. Discharging bulk cargo using? conveyor belts or similar systems aren't controlled and supervised the bulk cargoes form an elongated cone. The angle that is created by the cone is known as 'angle of repose'. It varies between cargos. Iron ore-based cargoes form a steep-angled cone whereas those that move freely create a cone with a shallow angle. A cargo that has low angles or repose could shift in the course of. As the cargo nears its completion, bulldozers could have been used to divide the load over a number of holds. Many dry-bulk carriers are dependent on facilities at the shore for cargo loading/discharge. However bulk carriers might be able to self-unload using conveyors under the cargo holds or on decks.
