Tanker Classification and Capacity

Tankers are classified based on their deadweight tonnage (DWT), which measures their cargo-carrying capacity. The Average Freight Rate Assessment (AFRA) system estimates a ship’s approximate capacity in barrels by utilizing 90% of its deadweight tonnage.

Key Facts

  1. Tanker Classification: Tankers are classified based on their deadweight tons (DWT), which is a measure of their cargo-carrying capacity.
  2. AFRA Scale: The Average Freight Rate Assessment (AFRA) system is used to classify tanker vessels. It estimates the approximate capacity of a ship in barrels by using 90% of its deadweight tonnage.
  3. General Purpose (GP) and Medium Range (MR) Tankers: These smaller tankers are commonly used to transport refined petroleum products over shorter distances. A GP tanker can carry between 70,000 and 190,000 barrels of motor gasoline, while an MR tanker can carry between 190,000 and 345,000 barrels.
  4. Long Range (LR) Tankers: LR class ships are the most common in the global tanker fleet. They can carry both refined products and crude oil. An LR1 tanker can carry between 345,000 and 615,000 barrels of gasoline or between 310,000 and 550,000 barrels of light sweet crude oil.
  5. AFRAMAX Vessels: AFRAMAX vessels refer to ships between 80,000 and 120,000 deadweight tons. They are popular with oil companies for logistical purposes.
  6. Very Large Crude Carriers (VLCC): VLCCs are responsible for most crude oil shipments globally. They can carry between 1.9 million and 2.2 million barrels of crude oil.
  7. Ultra Large Crude Carriers (ULCC): ULCC vessels can carry around 2 million to 3.7 million barrels of crude oil. They require special facilities and are limited in terms of loading and offloading locations.
