WORLD-WIDE Shipping's first double-hulled very large crude carrier (VLCC) of 300,000 deadweight tonne (dwt) was named Siam at the Daewoo Okpo Shipyard in South Korea recently. Another vessel, a single-hulled VLCC of 293,000 dwt, was named the Seki on the same day. It has been classed by Norwegian classification society Det Norske Veritas and complies with all major international conventions. ''There is great pressure on shipowners today to reduce tanker accident statistics and prevent oil pollution,'' said World-Wide chairman Helmut Sohmen. ''With further new vessels such as these built to the latest design standards, we hope to position World-Wide as a leading VLCC operator well into the next century.'' Mrs Judith Hurd, wife the British Secretary for Foreign and Commonwealth Affairs Mr Douglas Hurd, and Mrs Han Sung-mi, wife of the South Korean Foreign Minister, performed the naming ceremony of the two vessels. Mr Hurd, Mr David Wright, British Ambassador to Korea, Mr Y.S. Yoon, the vice-chairman of Daewoo Corp, and Mr W.S. Yune, president of Daewoo Shipbuilding and Heavy Machinery, also were present. The two tankers are the second and third vessels in a series of six VLCCs ordered in 1991 by WorldWide. Between 1988 and 1993, World-Wide was scheduled to receive 12 new VLCCs, including nine built by Daewoo, and a number of smaller newly built tankers. Although World-Wide has sold and scrapped seven large tankers last year, it still operates more than 30 VLCCs. World-Wide operates its fleet through offices in Tokyo, Hongkong, Singapore, London, Bermuda and New York.
