Greek shipowner John Angel-icoussis' acquisition of four ICB tankers last week was the highlight of a busier market, Allied Shipbroking Inc. said in its latest ship sales report. Angelicoussis paid $189 million in total for the Mindoro (1995-built, 300,294-deadweight tons), the Irian (1992, 286,006-dwt), the Ambon (1992, 285,771-dwt) and the Flores (1995, 284,410-dwt). Aegean Marine Petroleum, also of Greece, paid $2.5 million to buy the 1976 Norwegian-built tanker Maersk Ascension (60,810-dwt). Italian buyers also picked up two tankers last week. Gemarfin paid $8.75 million for the 1982 Japanese-built Meandros (40,632-dwt) while unknown Italian buyers paid $480,000 at an auction in the U.S. for the 1977 Italian-constructed Campo Duran (30,572-dwt).
