Mitsubishi Heavy Industries' plan to turn its Nagasaki plant into a cruiseship repair yard has been given an unexpected boost by the coronavirus.

The Japanese shipbuilder has won a contract to repair three Costa Crociere cruiseships after the Italian operator’s favoured Chinese yards were ruled out due to the spread of the disease.

High-cost Japanese shipbuilders would not normally expect to win cruiseship repair contracts in the face of cheaper Chinese competition.
