Cargo ships can be divided into two basic types. One type carries dry cargo,the other carries liquid cargo; however,an OBO ship is designed to carry both. A traditional dry cargo ship is the multi-deck vessel. Her holds are divided horizontally by one or two tweendecks,because these make stowage of individual packages easier. Dry bulk cargo is carried in bulk carriers. These do not have tweendecks as cargo is carried loose. The most modern type of dry cargo carrier is the container ship. They carry containers of standard dimensions,consequently stowage is easier. Fruit,meat and dairy produce are carried in refrigerated ships. Oil tankers are the most common type of liquid cargo carrier. They are often very large,because huge quantities of oil need to be transported and one large vessel is more economical to operate than two smaller ones. Two other types of liquid bulk carrier of growing importance are the liquefied natural gas (LNG) carrier and the chemical carrier,although chemical can also be carried in drums in general cargo ships. 009.
