Sanchi was a double-hulled crude oil tanker with an overall length of 274.18m (899.54feet), beam of 50m (160feet), and full-load draught of 17m (56feet). With a deadweight tonnage of 164,154 tons, the vessel was a typical Suezmax tanker, a vessel able to transit the Suez Canal in a laden condition. Sanchi was powered by an 18660kW MAN-B&W 6S70MC-C slow-speed diesel engine driving a fixed-pitch propeller and giving the tanker a service speed of 15.4kn.
The ship was built in 2008 by Hyundai Samho Heavy Industries at Yeongam, South Korea, for the National Iranian Tanker Company. It was named Saman but was renamed Sepid one month after delivery. In June 2012, it was renamed Gardenia and reflagged from Malta to Tuvalu. In November 2012, the name was changed to Seahorse and in August 2013, to Sanchi. The vessel was reflagged to Tanzania in April 2014 and to Panama in July 2016.
See main article: Sanchi oil tanker collision.
On January 6, 2018, Sanchi collided with the cargo ship CF Crystal and caught fire. This occurred 160nmi off of Shanghai, China in the East China Sea. Sanchi was travelling from Asaluyeh, Iran, to Daesan, South Korea. It was carrying natural-gas condensate (136,000 tonnes (960,000 barrels)) for South Korean petrochemical company Hanwha Total.
The fire burned for several days and part of the tanker exploded on January 10.[1] After further explosions, Sanchi sank on January 14, 2018. The entire crew of 32 died, with one body recovered from the sea and two from an onboard lifeboat.[2]
Extensive oil slicks were reported and the wreck, containing both cargo and fuel oil, lies in 115m (377feet) of water.[3]
