At least one person was killed on Tuesday and two others were missing after an oil tanker caught fire south of Lamma, with workers on board apparently jumping into the sea to escape.
More than 20 people were rescued, with four of them requiring hospital treatment. One was said to be seriously injured. The crew are believed to be from Vietnam.
Reports said explosions had been heard on the vessel and large amounts of dense, black smoke were billowing from the oil and chemical tanker.
It is believed that the tanker was being refuelled by a barge at the time and one Singaporean crew member from the barge was among the injured.
Police and firefighters said they received reports of the incident at around 11am.
Emergency crews were at the scene, with the fire still burning.
The 17,000-tonne Aulac Fortune, which is 144 metres long and 22.6 metres wide, set sail from Dongguan on Monday. The vessel is registered in Vietnam.
Residents on Lantau reported hearing a large blast on Tuesday morning, with some saying it had shaken their windows.
