HUMAN error is believed to have caused the collision between two Panamanian ships in thick fog off Hongkong yesterday.
The container ships Marine Brave and Wing Lee No 1 were separated in an eight-hour operation and returned to Hongkong under Royal Navy escort last night.
Their captains, from Germany and Hongkong, will face an inquiry today by the Panamanian Consulate.
Senior Marine Department officials were privately critical of the accident, which occurred at 6.30 am, but have no jurisdiction to investigate because the collision happened in international waters, 63 miles (about 100 kilometres) northeast of the territory.
''Royal Observatory fog warnings had been issued and these ships have radars and clear international conventions setting out the precautions necessary in poor visibility,'' said one official.
''Somebody wasn't doing their job properly.'' Department Senior Marine Officer (Search and Rescue), Mr Philip Weaver, said fog clearly contributed to a ''text-book collision''.
