The Chinese ship will become the fourth ship scouring a 120,000-square-kilometer (46,000-square-mile) expanse where Malaysia Airlines Flight 370 is thought to have crashed on March 8, 2014.
The search has had several setbacks through crew illness and equipment failures in recent months.
More than 85,000 square kilometers (32,800 square miles) of the search area have been scoured since late 2014, with Australia and Malaysia sharing the cost.
The Boeing 777 vanished after mysteriously flying far off course during a flight from Kuala Lumpur in Malaysia to Beijing. A wing flap found in July on the other side of the Indian Ocean when it washed up on Reunion Island is the only debris recovered.
Most of the 239 people aboard Flight 370 were Chinese. Australia is conducting the search on behalf of Malaysia, where the plane was registered.
