The two vessel orders underlined booming oil exploration around the world, Daewoo said in a statement on Friday, as crude oil futures have set a series of recent records.
The South Korean shipbuilder will deliver the drill ship for 580.9 billion won ($623.8 million) to an unidentified shipping firm from the Oceania Continent, while the crude oil carrier will go to a Europe-based shipper by the end of 2010.
Shares in Daewoo Shipbuilding rose 1.3 per cent to 54,700 won by 0243 GMT, with the broader market up 1.12 per cent.
