A second bid failed on Thursday to refloat a Malaysian ship carrying dangerous chemicals stranded on Australia's Great Barrier Reef but authorities said they would launch a new all-out effort on the weekend, Reuters reported. Queensland state Transport Minister Steve Bredhauer said three ocean-going tugs were unable to pull the 184-metre (600-ft) Bunga Teratai Satu off Sudbury Reef, despite early indications of improved buoyancy at high tide. "It is expected the next refloat operation will take place on the weekend, possibly early on Sunday morning when the tides will be more favorable," he said. An initial bid to move the stranded ship failed on Wednesday.
