Situated in East Asia, Taiwan is located very far from the Middle East and West Africa. To operate efficiently, a 300,000-ton oil tanker must usually visit two ports to fill up with crude during a single voyage then proceed to Taiwan, which increases the scheduling difficulties for taking on crude. In addition there are uncertain factors of ocean weather like hurricanes that force CPC personnel to continue keeping an eagle eye on the tankers.
地處東亞的台灣，距離中東與西非皆十分遙遠，為求經濟效益，30 萬噸的大油輪往往必須在一趟運油航程中，前往兩個港口裝滿油再航向台灣，裝油期程的安排難度相當高；加上颶風等海象天候的不確定因素，使得中油人員必須持續「緊迫盯船」。
