From the wires /// "Iran have chartered nearly 10% of the world tanker fleet for floating storage of crude oil. At the moment 30 VLCCs (Very Large Crude Carrier) and ULCCs (Ultra Large Crude Carrier) are anchoring outside the island Khark in the Persian Gulf. Last week the country reiterated its intentions to continue the nuclear programme but would not disclose the reason for chartering tankers for crude oil storage. The country is either preparing for war or just speculating on the oil price.
NOTE: Ahead of the first Gulf War, Iraq chartered crude oil tankers for floating storage."
