SINGAPORE, Nov 6 (Reuters) - The Asia-Pacific crude market held steady on Tuesday after Petronas sold December condensate at a similar premium compared with last month supported by firm naphtha cracks. Meanwhile, the market is not likely to receive Dar Blend supply soon as Sudan cancelled a tender to sell a November cargo. * TENDERS - Malaysia Petronas sold a 250,000-barrel cargo of Cakerawala condensate to BP at a premium of about $1 a barrel to dated Brent for loading on Dec. 25-27, a trade source said. - Sudan has cancelled a tender to sell 1 million barrels of Dar Blend crude for November, trade sources said. The tender would have been Sudan's first oil sale since fighting broke out between Khartoum and neighbouring South Sudan and halted crude exports early this year. The reason for the cancellation was not immediately clear, but a trade source said it may have been due to ownership issues. "This is oil that was left in storage tanks so I don't think they have decided whether it belongs to the north or the south," he said. * MARKET NEWS - Vietnam's second refinery is likely to start operating in 2016, two years later than scheduled, as the final investment decision has run into snags related to currency conversion and construction costs, Idemitsu Kosan said. - Thailand's Bangchak Petroleum Pcl is studying a plan to build a second refinery with capacity of 150,000 barrels per day (bpd) to tap demand in the fast-growing Southeast Asian country. - Taiwan's Formosa Petrochemical Corp will also shut a 180,000 bpd crude distillate unit for approximately 45 days between March and June next year, its spokesman said. - South Korea has closed two nuclear power reactors for nearly two months of unscheduled maintenance to replace parts that had been provided with forged certificates, the ministry of knowledge economy said. - Dubai-based NetOil, led by Middle Eastern businessman Roger Tamraz, has submitted a new offer to take over France's oldest refinery, unveiling a last minute deal with British oil major BP and Hyundai.
