The 70-meter cargo ship Ying Hai sank in the Taiwan Strait on Wednesday after it developing a heavy list on a voyage from Kaohsiung city to Busan Korea.
The Taiwanese-flagged ship notified Taiwan search and rescue authorities on Tuesday that the ship had developed a list after some containers on deck had shifted in heavy weather.
After attempts to tow the vessel failed, all 9 crew members eventually abandoned ship to SAR boats, leaving the vessel adrift.
Authorities tracking the ship said it sank Wednesday morning south of the Penghu archipelago.
Ships in the area are being warned to keep a lookout for possible floating containers in the water.
