DUBAI, United Arab Emirates (AP) _ The world's largest ship, shattered by Iraqi missiles during the Iran-Iraq tanker war, sailed today out of repair dry docks.

The Norwegian-owned Jahre-Viking left Dubai for Saudi Arabia's Ras Tanura terminal, on charter to the U.S. Exxon Corp. to load half a million barrels of oil destined for the Gulf of Mexico.

It was the Jahre-Viking's first shipment since May 1988, when the vessel - then called the Seawise Giant - was attacked.

The ship was used by Iran as a huge oil storage tanker. It was anchored just outside the Strait of Hormuz, feeding several smaller tankers, when Iraqi missiles set it and the other ships ablaze. At least 20 crew members aboard the ships were killed.

The 564,739-ton ultra-large crude oil carrier is 1,471 feet long and 226 feet wide. It is about a third wider and longer than the U.S. aircraft carriers that Iraq's later invasion of Kuwait brought regularly into the Persian Gulf.

The $60 million refurbishment cost three quarters of the vessel's total value of $80 million, said Henrik Lian, the technical director for Jorgen Jahre Shipping, which is the managing partner for KS Jahre Viking.
