John Fredriksen said he is always eyeing potential additions to his tanker fleet after the Norwegian tycoon's Frontline spent $566.8m to buy six VLCC newbuildings.

TradeWinds reported on Tuesday that New York and Oslo-listed Frontline, which has Fredriksen as its chairman and largest shareholder, agreed to buy the tankers under construction at Hyundai Heavy Industries.

They are believed to have been ordered by Greek shipowner Evangelos Pistiolis' Central Shipping.
