LR1/LR2 tanker

LR1 and LR2 are the long-range product tanker classes that carry refined petroleum and sometimes dirty cargoes over the longest clean-product legs. An LR1 runs about 55,000 to 80,000 dwt on a Panamax beam, the old Panama Canal lock limit of 32.3 meters; an LR2 runs about 80,000 to 160,000 dwt on an Aframax hull. The two share their hull forms with crude Panamax and Aframax tankers, so an LR2 can switch between clean products and dirty crude depending on the market. The long-range fleet moves naphtha, jet fuel, and gas oil between Middle East and Indian refineries and Europe or Asia.
