A supertanker is a large ship designed to transport vast quantities of liquid cargo, primarily crude oil. These vessels can carry over 300,000 deadweight tons, making them some of the largest ships in the world. Supertankers are essential for global trade, as they facilitate the movement of oil from production sites to refineries. The design of a supertanker includes a double-hull structure for safety, reducing the risk of spills. They are often equipped with advanced navigation and communication systems to ensure efficient and safe passage across oceans. Supertankers play a crucial role in the oil industry and the global economy.
