A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo—such as grain, coal, ore, steel coils, and cement—in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to increased size and sophistication of these ships.
Bulk cargo refers to material in either liquid or granular, particulate (as a mass of relatively small solids) form, such as petroleum/crude oil, grain, coal, or gravel. This cargo is usually dropped or poured, with a spout or shovel bucket, into a bulk carrier ship's hold , railroad car / railway wagon , or tanker truck / trailer / semi ...
Handymax Bulk Carrier "Orientor 2" Handymax and Supramax are naval architecture terms for the larger bulk carriers in the Handysize class. Handysize class consists of Supramax (50,000 to 60,000 DWT), Handymax (40,000 to 50,000 DWT), and Handy (<40,000 DWT). The ships are used for less voluminous cargoes, and different cargoes can be carried in ...
This is a list of bulk carriers, both those in service and those which have ceased to operate. Bulk carriers are a type of cargo ship that transports unpackaged bulk cargo . For ships that have sailed under multiple names, their most recent name is used and former names are listed in the Notes section.
Handysize is a naval architecture term for smaller bulk carriers or oil tanker with deadweight of up to 50,000 tonnes, [1] although there is no official definition in terms of exact tonnages. Handysize is also sometimes used to refer to the span of up to 60,000 tons, with the vessels above 35,000 tonnes referred to as Handymax or Supramax.
[1] [2] An example of ships of this size is the Valemax bulk carriers. The standard was originally developed to carry very large loads of iron ore to China from Brazilian port facilities operated by mineral firm Vale. [1] [2] Correspondingly, harbours and other infrastructure that are "Chinamax-compatible" are those at which such ships can ...
An ore-bulk-oil carrier, also known as combination carrier or OBO, is a ship designed to be capable of carrying wet or dry cargoes. The idea is to reduce the number of empty ( ballast ) voyages, in which large ships only carry a cargo one way and return empty for another.
An ore-bulk-oil carrier, also known as combination carrier or OBO, is a ship designed to be capable of carrying wet or dry bulk cargoes. [111] This design was intended to provide flexibility in two ways. [112] Firstly, an OBO would be able to switch between the dry and wet bulk trades based on market conditions. [112]
