⭐ Core Definition: Petroleum tanker

An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.

Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight (DWT) to ultra-large crude carriers (ULCCs) of 550,000 DWT. Tankers move approximately 2.0 billion metric tons (2.2 billion short tons) of oil every year. Second only to pipelines in terms of efficiency, the average cost of transport of crude oil by tanker amounts to only US$5 to $8 per cubic metre ($0.02 to $0.03 per US gallon).

👉 Petroleum tanker in the context of Aframax

An Aframax vessel is an oil tanker with a deadweight between 80,000 and 120,000 metric tonnes. The term is based on the Average Freight Rate Assessment (AFRA), a tanker rate system created in 1954 by Shell Oil to standardize shipping contract terms.

Due to their favorable size, Aframax tankers can serve most ports in the world. These vessels serve regions that do not have very large ports or offshore oil terminals to accommodate Very Large Crude Carriers and Ultra-Large Crude Carriers. Aframax tankers are optimal for short- to medium-haul crude oil transportation. Aframax class tankers are largely used in the basins of the Black Sea, the North Sea, the Caribbean Sea, the South and East China Seas, and the Mediterranean. Non–OPEC exporting countries may require the use of this type of vessel because the harbors and canals through which these countries export their oil are too small to accommodate the Suezmax or the larger categories.

Petroleum tanker in the context of Tanker (ship)

A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tanker ship include the oil tanker (or petroleum tanker), the chemical tanker, cargo ships, and a gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine.

In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker.
