A supertanker is a huge vessel used for transporting crude oil, petroleum, or other liquids in bulk quantities. It is one of the largest types of ships in the world and can be as long as 1,200 feet and weigh up to 400,000 tons. Synonyms for supertanker include oil tanker, crude carrier, liquid carrier, giant tanker, and ocean liner. These vessels are crucial for transporting oil products from one part of the world to another, and their sheer size and capacity make them a formidable force in the shipping industry. Despite their importance, supertankers are also a cause for environmental concern due to the potential for oil spills and accidents.
