An Aframax ship is an tanker
with a deadweight
tonnage of between 80,000 and 120,000 dwt, and carries between 70,000 and 100,000 metric tonne
s of crude oil
. This makes them smaller than VLCC
tankers. They are used primarily in regions which, unlike most OPEC
countries, do not operate harbor
s large enough or have offshore oil terminal
s to allow the larger crude carrier ships to operate. The name Aframax
does not refer to Africa
, but rather to the Average Freight Rate Assessment
system, created by Shell Oil
in 1954 to standardize contract terms. The Aframax is the largest size tanker assessed by the system.
Aframax ships are crude carriers; that is, they transport crude oil, and are sometimes called 'dirty' tankers. If a ship of this size is used to transport refined products such as gasoline, jet fuel or methane, it will have coated cargo compartments to reduce contamination, and is designated an 'LR2 tanker.'
From Imarex - a maritime derivatives market - the average dimensions of an Aframax ship are as follows:
- Length: 243.2 m
- Breadth: 41.6 m
- Draft: 14.1 m
- Barrel Intake: 690,000 bbl
- Speed: 14.7 knots
Bear in mind that these are average figures.
