Showa Shell and Fuji Oil will fully load Iranian crude on the VLCC Tsugaru, the source said.
A Fuji Oil spokesman confirmed on Wednesday that the refiner was jointly lifting an Iranian crude cargo with Showa Shell on the tanker, which is scheduled to arrive in Japan in mid-February.
The latest lifting comes days after Fuji Oil and Showa Shell loaded the first Iranian crude oil cargo to be lifted by the Japanese refiners, as well as by Japan, since the country won the 180-day sanctions waiver on November 5.
Platts trade flow software cFlow showed the cargo-laden VLCC Kisogawa left Iran's Kharg island on Sunday bound for Kawasaki, Tokyo Bay. It is now estimated to arrive at Kawasaki on February 9, according to cFlow.
Fuji Oil and Showa Shell are Japan's main buyers of Iranian crude. Fuji Oil, in which Showa Shell has a 6.57-percent stake, operates the sole 143,000 bpd Sodegaura refinery. Showa Shell also operates the 70,000 bpd Keihin refinery in Kawasaki.
Fuji Oil and Showa Shell's loading of Iranian crude comes after Platts reported on January 15 that major Japanese banks are set to resume Iranian oil transactions after receiving final regulatory clearance, paving the way for the country's refiners to begin loadings as early as this month.
Japanese refiners and shipping companies recently resolved their concerns over relevant shipping insurance for Iranian imports and were awaiting bank and regulatory approval before resuming inflows.
