The Fugro Supporter will become the fourth ship to join the search for MH370 in the southern Indian Ocean.
A fourth ship will join the underwater search for missing Malaysia Airlines flight 370.
The Joint Agency Co-ordination Centre said Fugro Supporter would join fellow ships Fugro Equator and Fugro Discovery in the Indian Ocean search zone later this month.
Fugro Supporter has been equipped with a Kongsberg HUGIN 4500 autonomous underwater vehicle, which will scan parts that cannot be examined effectively by equipment on the other vessels.
"It is not connected to the ship by cable, but is rather deployed with a pre-programmed area of the sea floor to investigate," JACC said.
After each underwater mission, the vehicle will ascend automatically and return to the Fugro Supporter so the data can be downloaded and the vehicle's batteries changed.
Fugro Equator and Fugro Discovery both departed Fremantle at the weekend and are expected to arrive back in the search area on Thursday.
GO Phoenix left Fremantle on January 5 and recommenced its underwater search operations on Monday.
If there are no major delays, investigators could finish scouring the priority zone by May.
More than 200,000sq km have been surveyed and 14,000sq km of the sea floor have been searched.
MH370, carrying 239 passengers and crew, disappeared on March 8 en route from Kuala Lumpur to Beijing.
