A specially-designed mode of transport for conveying liquid and gas is a tanker. A tanker is a ship or a truck that is designed to transport large amounts of liquid or gas cargo. Tankers are specially built with large, cylindrical tanks to store and transport these materials safely. They are used to transport a wide range of liquids and gases, including crude oil, gasoline, chemicals, liquefied natural gas (LNG), and more. Tankers are an essential component of the global transportation network, as they allow for the efficient and safe transport of large quantities of liquids and gases across long distances.
