A new lawsuit against Mediterranean Shipping Co (MSC) in New Orleans has unveiled details of an arbitration fight in London that found the liner giant liable to an affiliate of shipowner Conti over the MSC Flaminia explosion.

A series of decisions by a three-arbitrator panel found that MSC, which had the container ship on charter at the time of the July 2012 incident, was not negligent in shipping the cargo of hazardous divinylbenzene (DVB) that sparked the blast.
