INFORMATION supplied by the Marine Department may have resulted in the wrong ship being prosecuted in China for an accident near Hong Kong which killed six people. The Supreme Court in Beijing will this month decide whether owners of the ship named by the department should pay US$1 million (HK$7.73 million) in compensation to the victims' families. A frontier guard was among those killed when a container ship collided with security vessel Shan Wei 27 kilometres southwest of Waglan Island on November 25, 1992. The name of mainland-owned container ship Trade Expansion - thought at the time to have been the only ship from Hong Kong in the area - was given to the Guangzhou Maritime Superintendent Bureau by the department two days later. But information about another ship, which reported a collision in the area at the time, was overlooked and only given to mainland authorities after an inquiry had been held. The inquiry formed the basis of the facts relied on in two subsequent court cases which pinned the blame on the Trade Expansion. Sources said the Supreme Court was unlikely to overturn the decisions of the lower courts, which relied on the initial findings of inquiries by maritime superintendencies. Should the court rule the Trade Expansion was not to blame, compensation is unlikely ever to be paid because legal proceedings against another ship could be 'time-barred'. Documents obtained by the South China Morning Post suggested the Trade Expansion was not the ship involved. Department records show there were two container ships in the area - the other the Qatar-registered Bar'zan. The department was unable to confirm when it notified the Guangdong authorities about the second ship, but it was understood the information was not originally passed to the inquiry. Radar tracks recorded by the department's Vessel Traffic Centre showed the Bar'zan turned sharply to port at the time the collision was thought to have occurred. A copy of a statement by Bar'zan captain, U. P. S. Baveja, shows this was due to a collision with a smaller vessel. Records showing the position of the wreck, rescue of the survivors, and currents are inconsistent with the mainland's official version of events.
