On the morning of December 17, the 27 meter long fishing vessel QNa 91917-TS caught fire in the Gulf of Thailand approximately 110 nautical miles northeast of Da Nam Island, Vietnam. The QNa 91917-TS  had been fishing for squid when a fire broke after an electrical short in the engine. The fire quickly spread through the vessel  and could not be contained by the crew.

The QNa 91917-TS sent out a distress call with Vietnamese authorities responding. Authorities reached out to nearby fishing vessels to assist.  The Ng 95454-TS, QNg 95179-TS, QNa 91234-TS, and PY 90779-TS responded and proceeded to the aid of the QNa 91917-TS. Before the fishing vessels could reached the stricken QNa 91917-TS, all 52 crew members were forced to abandon ship into life rafts before the vessel succumbed from the fire and sank.  The 52 crew were rescued by the fishing vessels a short time later.  The crew were later transferred to a Vietnamese Coast Guard vessel which proceeded to Song Tu Tay Island.
