The Dong Hai Jiu 101 will join three other vessels contracted from Dutch firm Fugro -- Fugro Discovery, Fugro Equator and Havila Harmony -- currently scouring the depths of the southern Indian Ocean off Western Australia where the plane is believed to have crashed after diverting from its flight path.
Carrying 239 passengers and crew, the plane disappeared during a Kuala Lumpur-Beijing flight on March 8, 2014.
