Ships heading for Ukrainian ports through the Black Sea maritime corridor set up for the World Food Programme (WFP) are mostly older, smaller bulkers with low market values.

Using data sourced from VesselsValue, TradeWinds calculates that the 12 vessels listed by the United Nations as undergoing inspection in Istanbul before heading for Ukrainian Black Sea ports have an average age of 20.1 years and an average market value of $6.5m.

One vessel, the 12,000-dwt Kubrosli Y, is 41 years old.
