SPP Shipbuilding of Korea has won an additional order for four MR tankers.
Ceres Shipping and JP Morgan jointly ordered the four fuel-efficient newbuildings (options exercised) after they booked four such ships earlier this year in May.
The 51,000DWT PCs are priced at $33.5m per ship on average, with the later quartet a bit cheaper, informed sources say.
They are set to be delivered from 2013 by 2014.
