Figure 43: Historical development of average ship size of cellular fleet
For the oil tankers, we derive the number of ships per size category, applying the first methodology (see Figure
41) to derive the distribution of the capacity over the ship size categories as well as the expected average size
of the ships per size category.
Tankers are usually divided in several size categories:
• Small
• Handysize
• Handymax
• Panamax
• Aframax
• Suezmax
• Very large crude carrier (VLCC)
• Ultra large crude carrier (ULCC).
The sizes of these ships differ somewhat. For the purpose of our inventory model and ship projection model,
the following bins have been defined:
Table 38 – Size bins for tankers
Capacity range (dwt) Size category
0–4,999 Small
5,000–9,999 Small
10,000–19,999 Handysize
20,000–59,999 Handymax
60,000–79,999 Panamax
80,000–119,999 Aframax
120,000–199,999 Suezmax
200,000–+ VLCC, ULCC
