Mediterranean Shipping Co is disputing an alleged breach of the IMO's ban on carrying high sulphur fuel oil (HSFO) in the United Arab Emirates.

The country's Federal Transport Authority (FTA) for land and maritime said in a circular on Monday that the 9,200-teu boxship MSC Joanna (built 2006) would be banned from its ports and waters for a year.

The vessel's master has also been prohibited from entering the country on any other ship.
