South Korea's Dae Sun Shipbuilding & Engineering has added four feeder container ship newbuildings worth nearly $88m to its orderbook.
The midsize shipbuilder said two companies each ordered a pair of gearless 1,000-teu ships.
It declined to disclose the names of the buyers, citing contract confidentiality.
However, shipbuilding sources familiar with the deals said Greece's Cosmoship Management and domestic liner company Namsung Shipping have signed the contracts, which do not include any options.
