What are the sizes of oil tankers?

Oil tankers vary in size and are classified into several categories based on their deadweight tonnage (DWT). The smallest, known as coastal tankers, can carry around 5,000 to 20,000 DWT. Medium-sized tankers, called Aframaxes, typically hold between 80,000 to 120,000 DWT. The largest tankers, known as Very Large Crude Carriers (VLCCs), can carry between 200,000 to 320,000 DWT, while Ultra Large Crude Carriers (ULCCs) can exceed 320,000 DWT.
