The Sanchi oil tanker collision occurred on 6 January 2018 when the Panamanian-flagged, Iranian-owned tanker Sanchi, with a full natural-gas condensate cargo of 136,000 tonnes (960,000 barrels), sailing from Iran to South Korea, collided with the Hong Kong-flagged cargo ship 160 nautical miles (300 km) off Shanghai, China. Sanchi caught fire shortly after the collision; after burning and drifting for over a week, it sank on 14 January. None of Sanchi's 32 crew members survived.
