ultralarge crude carrier
Quick Summary
An Ultralarge Crude Carrier (ULCC) is a type of ship designed to transport crude oil in bulk. ULCCs are the largest class of oil tankers, with capacities ranging from 320,000 to over 550,000 deadweight tons (dwt). These massive vessels can carry between two million and over three million barrels of crude oil. They typically measure around 415 meters (1,350 feet) in length. While the direct cost of transporting oil decreases with increased tanker size, the limited availability of suitable port facilities has resulted in only a small number of ULCCs being built. Concerns over pollution from tanker accidents have led to stricter regulations, including requirements for double hulls on new and existing tankers.12
