Chief executive Nils Andersen identified Maersk Line, APM Terminals and Maersk Oil as the star performers in the quarter as he revealed the company now expects to record a gain of $4.5bn this year.

The world’s largest shipowner, which today unveiled a $1bn share buyback programme, had previously guided for a gain of $4bn in 2014.

RS Platou Markets says the strong performance of Maersk Line is the major reason behind the improved profit forecast, which moves the company’s own estimate closer to the $4.46bn
