What is Bulk Shipping?
Bulk shipping is the transportation of goods in large quantity, usually not packed but loaded directly into a vessel. Such goods are grains, petroleum products, iron ore and more. These type of goods are referred to as bulk cargo. Bulk cargo is unpacked dry cargo. Examples include grain, coal, and iron. However, bulk cargo can also contain liquid bulk. For this reason, specialised trucks and containers are used.
Tanker Shipping
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 carrier. Tankers also carry commodities such as vegetable oils, molasses and wine. In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker. Tankers were first developed in the late 19th century as iron and steel hulls and pumping systems were developed. As of 2005, there were just over 4,000 tankers and supertankers 10,000 LT DWT or greater operating worldwide. Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specialized inland-waterway tankers which operate on rivers and canals with an average cargo capacity up to some thousand tons.
