NITC's burning suezmax Sanchi is still at risk of an explosion or sinking, according to Chinese authorities.

AFP also cited China's transportation ministry as saying there was still no sign of survivors 36 hours after the 164,000-dwt Sanchi (built 2008) was damaged and caught fire in a collision with CoscoCS' 76,000-dwt bulker CF Crystal (built 2011) off Shanghai.

The vessel has been leaking its condensate cargo into the sea.
