The 9 biggest oil spills in Thai history

The Koh Samet oil spill disaster may seem huge today, but it is only the third biggest oil spill ever recorded in Thai waters, according to the Thai Marine Knowledge Hub (MKH).

The government’s Marine Department defines a major oil spill as a disaster that releases over 20,000 liters of oil into the sea. The current spill, caused by an offshore PTT Global Chemical Plc (PTTGC) pipeline leak, is believed to have poured more than 50 tons or 50,000 liters of crude oil into the Gulf of Thailand.
