Swedish owner Wisby Tankers is embarking on its biggest ever invest programme by ordering two 37,000-dwt bitumen carriers at Hyundai Mipo Dockyard (HMD) in South Korea.

The ships are set for delivery in 2017 and sources suggest they are costing $50m each. Managing director Jonas Engstrom confirms the deal but declines to comment on the price.

Some indicate the newbuildings have alredy been lined up for long-term charter to Trafigura but Engstrom says nothing has yet been decided regarding employment.
