Oil tankers are large ships specifically designed to transport liquid petroleum products across oceans and seas. They come in various sizes, with the largest being called Very Large Crude Carriers (VLCCs). These vessels have specialized tanks that can hold millions of barrels of oil, ensuring safe and efficient transportation from oil-producing regions to refineries and markets around the world. To prevent spills and environmental damage, oil tankers are equipped with advanced safety features, including double hulls and sophisticated pumping systems. Regulations, such as those set by the International Maritime Organization (IMO), help ensure that these ships operate safely and minimize the risk of accidents during transit.
