A tanker (or tank ship or tankship) is a merchant vessel designed to transport liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. Tankers used for liquid fuels are classified according to their capacity. The small coastal tanker Pegasus on the River Weser. The Very Large Crude Carrier (VLCC) MV Sirius Star in 2008 after her capture by Somali pirates. In 1954, Shell Oil developed the average freight rate assessment (AFRA) system which classifies tankers of different sizes. To make it an independent instrument, Shell consulted the London Tanker Brokers’ Panel (LTBP). At first, they divided the groups as General Purpose for tankers under 25,000 tons deadweight (DWT); Medium Range for ships between 25,000 and 45,000 DWT and Large Range for the then-enormous ships that were larger than 45,000 DWT. The ships became larger during the 1970s, and the list was extended, where the tons are long tons: 10,000–24,999 DWT: General Purpose tanker; 25,000–54,999 DWT: Medium Range tanker; 55,000–79,999 DWT: Long Range 1 (LR1); 80,000–159,999 DWT: Long Range 2 (LR2); 160,000–319,999 DWT: Very Large Crude Carrier (VLCC); 320,000–549,999 DWT: Ultra Large Crude Carrier (ULCC).
