Sungdong Shipbuilding & Marine Engineering has formally signed an order for four 3,600-teu containerships from Zodiac Maritime of the UK.
They are set for delivery in 2013 but newbuilding values are yet to be revealed.
But industry sources reckon the ship price is in the range of $48m-$51m per ship, similar with the 3,600-teu ships inked by Germany's NSC in April.
The final contract follows a basic agreement between the yard and owner in April.
With the contract, Sungdong has inked fourth containership order to date this year.
The South Korean shipyard secured 11 8,800TEU's as well as six 3,600TEU's and is also in final talks for 10, 4,700TEU's.
