Container line Mediterranean Shipping Company (MSC) is shifting the world's biggest boxship to the US following cancelled sailings in Asia.

It had already moved two 19,000-plus teu vessels into transpacific trades and is now redeploying two of its "megamax-24" units.

The first of these, the 23,756-teu MSC Mia (built 2001) is joining the transpacific leg of its North Europe-Far East-US west coast service, operated with 2M partner Maersk.
