Hitachi Zosen Corp., a major Japanese shipbuilder, won 29 billion yen worth of orders from Bergesen D.Y. Group ASA of Norway for four 300,000-ton oil tankers. The tankers will be delivered between March 31, 2000 and January 31, 2001, a spokesman for Hitachi Zosen said. Hitachi Zosen posted a parent current loss of 17.49 billion yen for the year ended March 1999, its first current loss in 10 years, against current profit of 7.02 billion a year earlier, mainly due to losses from unprofitable overseas business.
