Aframaxes can generally transport from 500,000 to 800,000 barrels of crude oil and are also used in Lightering. A coated Aframax operating in the refined petroleum products trades may be referred to as an LR2.

Ballast — Any heavy material, including water, carried temporarily or permanently in a vessel to provide desired draft and stability.

Bareboat charter—A charter under which a customer pays a fixed daily or monthly rate for a fixed period of time for use of the vessel. The customer pays all costs of operating the vessel, including voyage and vessel expenses. Bareboat charters are usually long term.

b/d—Barrels per day.

Charter—Contract entered into with a customer for the use of the vessel for a specific voyage at a specific rate per unit of cargo (“voyage charter”), or for a specific period of time at a specific rate per unit (day or month) of time (“time charter”).
