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 the global oil trade, as they efficiently move oil from production sites to refineries and markets. The design of a supertanker includes a double-hull structure, which enhances safety by reducing the risk of spills. They are equipped with advanced navigation and communication systems to ensure safe passage through busy shipping lanes. Supertankers play a crucial role in the economy, impacting the price of oil and energy resources globally.
