Who is Ga-Hyun Chung, and what role did his company Sinokor Group play in UAE oil exports during the Iran war?

Ga-Hyun Chung is an intensely private Korean shipping tycoon whose company, Sinokor Group, played a crucial role in enabling the UAE to maintain and rapidly scale crude oil exports through the Strait of Hormuz during the Iran war by leasing supertankers to Abu Dhabi National Oil Co. (Adnoc) for risky 'shuttle runs' — including 'dark' transits without transponders — starting from at least mid-April; by June, nearly half of Emirati crude shipments were on Sinokor-controlled vessels, according to Vortexa ship tracking data.

How much revenue did Sinokor potentially earn from its shuttle-run contracts with Adnoc, and what evidence supports this estimate?

Brokers estimated that just three tankers conducting shuttle runs for Adnoc since mid-April could have earned Sinokor between $60 million and $120 million, though the exact terms of the deals were not disclosed; this estimate is based on industry conversations cited in the article and reflects the surge in tanker rates during the Iran war turmoil.
