The Baltic Exchange is based in London and provides a range of indices benchmarking the cost of moving bulk commodities, dry and wet, along popular routes around the seas. Some of these indices are also used to settle Freight Futures, known as FFA's. The most famous of the Baltic indices is the Baltic Dry Indices, commonly called the BDI.
The term "dry bulk carrier" is used to distinguish bulk carriers from bulk liquid carriers such as oil, chemical, or liquefied petroleum gas carriers. Very small bulk carriers are almost indistinguishable from general cargo ships, and they are often classified based more on the ship's use than its design.
Dry bulk A variation of the liquid tank trailer, with a funnel-shaped bottom, used for hauling bulk quantities of dry powder (sometimes called bulk pneumatic). Sometimes referred to as a 'Teat Truck' or 'Teater' due to its appearance. Usually loaded through holes in the top, unloaded through the bottom or through pneumatic force. [10] [46] Dry van
For the dry bulk density, the sample is oven dried and weighed, giving the mass of soil solids, M s. The relationship between these two masses is M t = M s + M l, where M l is the mass of substances lost on oven drying (often, mostly water). The dry and wet bulk densities are calculated as Dry bulk density = mass of soil/ volume as a whole
Smaller quantities (still considered "bulk") can be boxed (or drummed) and palletised. Bulk cargo is classified as liquid or dry. Bulk liquid cargo: Weighable No No A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas ...
Baltic Dry Index 1985 - 2022. The Baltic Dry Index (BDI) is a shipping freight-cost index issued daily by the London-based Baltic Exchange. The BDI is a composite of the Capesize, Panamax and Supramax timecharter averages. It is reported around the world as a proxy for dry bulk shipping stocks as well as a general shipping market bellwether.
They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Container ship capacity is measured in twenty-foot equivalent units (TEU). Tankers carry petroleum products or other liquid cargo. Dry bulk carriers carry coal, grain, ore and other similar products in loose form.
A dry bulk cargo barge is a barge designed to carry freight such as coal, ores, grain, sand or gravel, or similar materials. Barges are usually constructed of steel. They have an outer hull, and one or more internal holds. A rake barge has a bow shaped to cause less resistance when being pushed and is usually placed at the head of the tow.
