An email with spectacular photos of a fire and oil spill in China is circulating around the industry (I’ve received it twice) but it doesn’t have any information on the incident.
It actually happened back in mid-July. The same set of photos but with captions can be found here. And there is a little more information on the incident in Wikipedia. However the cause of the incident is not clear. There are references to ship unloading, pipeline failures (DN 700 and DN 900) and addition of a “catalyst” to a tank, and the truth probably contains all of these elements. But it doesn’t seem to be a transmission pipeline failure.
