Iran Threatens Largest Tanker Owner Iran has threatened South Korean tanker giant Sinokor, the world's largest owner of ultra-large tankers, with sweeping measures against its fleet from November 1, accusing the company of repeatedly violating Tehran's restrictions on shipping through the Strait of Hormuz. Sinokor ships have committed more transit violations than any other operator over the past three months, and action has already been taken against at least 7 ships to curb the violations. The agency warned shipowners, charterers and insurers that all vessels associated with Sinocor would face "legal action". Sinokor-controlled tankers carried about 105.6 million barrels of crude through the Strait of Hormuz in September, accounting for 37% of the total, according to a Bloomberg analysis of vessel tracking data. According to reports, at least 7 Sinocor-related tankers were hit by missiles or UAVs during the conflict. The Korean Shipowners' Association denied Tehran's accusations, saying the vessels involved in the dispute were chartered by a foreign oil company and had no South Korean crew members on board.
