Hyundai Heavy Industries Co., the world's leading
shipbuilder, said Saturday that it has successfully built two drill ships.
It marks the first time that the South Korean company has built such ships used to explore for oil in deep water.
The drill ships, 229.22 meters long, 36 meters wide and 18.3 meters high, will be delivered by May 2011 after tests.
Hyundai Heavy said it is currently working on building its third drill ship.
In the first seven months of the year, Hyundai Heavy earlier said orders for ships and plants have more than doubled to US$11.3 billion compared to the same period in 2009.
Sales gained 4.5 percent in July from a year earlier to 1.65 trillion won, it said.
