John Fredriksen has signed for up to four kamsarmax bulker newbuildings in China in the latest move to expand his private dry cargo orderbook.

The Norwegian shipowner's Seatankers has booked two firm vessels at Dalian Shipbuilding with options for two more.

Fredriksen is believed to be paying between $24m and $25m for each of the slots, with the firm ships set for delivery in 2019 and the options pencilled in to arrive in 2020.
