oil tanker
An oil tanker is a ship that transports petroleum to a tank installed in a hull. It is generally called a tanker, and it is different from container line and structure. After the Second World War, the production and demand for petroleum increased sharply, and oil tankers, which transport crude oil from the mountain to the consumer area, were built. In addition, since it is advantageous to the operating economy, it has been gradually increased in size and speed. The big ones weigh 650000 tons. Since 1878, it has flown from crude oil mining sites to refineries and sold various petroleum and petrochemical products to consumers. It is roughly divided into navy-owned ships and commercial ships. A tanker is a transport machine that transports liquids. It is called a tanker since a large tank is installed in the hull. In general, oil tankers are often referred to as "tankers", so vessels transporting liquefied natural gas are distinguished from LNG tankers, chemical tankers, and chemical tankers.
