17. While you read Read the passage and do the following tasks: Task 1: Complete the table: carry liquid cargo Tankers Functions Names of ship
18. Since the dawn of history, boats have been used in rivers, and ships have been used to cross seas and oceans, to carry goods and people from one to another. The volume of cargo carried by ships continues to increase, and ships become larger and faster. The variety of cargo is also widening. For this reason, many ships are built for particular cargoes. Tankers carry liquid cargo such as petroleum, and refrigerated cargo is carried in reefers. Other ships, called bulk - carriers, carry certain cargoes such as iron ore, grains or timber in bulk. Many vessels are built for certain duties; tugs for towing ships, dredgers for deepening channels, and specialist crafts, such as gas carriers, ice - breakers and floating cranes.
19. New types of ships include container vessels and Ro - Ro ships. Container vessels carry large cases or containers, of a wide variety of goods. They have a high service speed and can be loaded and discharged very rapidly. “Ro-Ro” ships have doors in their bows and sterns. These doors allow lorries, with cargo on them, to be driven on and off. Another new type of ship is the Lash - ship. The word “ Lash” stands for “ lighter aboard ship”. Lash - ships carry lighters or floating containers. Tankers known as VLCCs (Very Large Crude Carriers) are designed to carry over 200,000 tons. ULCCs (Ultra Large Crude Carriers) can carry over 400,000 tons of cargo. Although there is a wide variety of ships at the present time, more new designs are expected.
