Over the past six months, STS (ship-to-ship) transshipment of crude oil from the Gulf of Oman and the Persian Gulf has been frequent. However, data shows that the technical barriers to STS operations for LNG and LPG are extremely high (LNG requires ultra-low temperatures of -162°C and vacuum-insulated hoses, facing the risk of hull brittleness and explosion, with a complexity rating of "extremely high"). Recent evidence suggests that under extremely urgent shipping demands, some carriers are taking the risk of such high-risk operations, raising concerns about potential shipping disasters and energy supply chain disruptions.
