Cosco Shipping Lines has said it is not the operator of the panamax containership which lost an undisclosed number of containers in a Pacific storm.

The 4,526-teu Cosco Nagoya (built 2008) was understood to have lost containers en route to Long Beach, a day after departing from the Busan New Port in South Korea, on 23 November.

Around 59 containers are estimated to have been damaged or lost.
