CHEF Paul Chung played a key role in an attempt to rescue an oil tanker threatening to cause one of the world's worst environmental disasters. Still in his chef's tunic, Hong Kong-born Mr Chung, 29, was plucked from cooking the evening dishes at his Happy Garden Chinese takeaway in the Welsh port of Milford Haven to act as interpreter for the salvage operation. Rescuers trying to prevent millions of tonnes of crude oil leaking from the stricken Liberian tanker Sea Empress damaging the South Wales coast, called on Mr Chung to translate instructions to the all-Chinese crew of a tug boat, the sixth most powerful in the world. 'I was taken to the port offices and translated instructions in Cantonese over the radio,' Mr Chung said. 'We managed to get the tug's line connected to the tanker to hold it in place.' Mr Chung, who left Hong Kong with his family when he was 10, worked with the rescue services for three hours before the tug, based in Cornwall, left the scene. Despite their efforts, the tanker could not be pulled off the rocks, but later attempts were more successful. Last night the tanker was being moved to a safer anchorage.
