The joint exercise is being conducted at Port Blair under the aegis of the Andaman and Nicobar Command.
"Apart from securing the trade sea route, the coordinated patrol also serves to enhance mutual understanding and inter- operability between the two navies," the Indian Navy said in a statement.
The two navies have been carrying out Coordinated Patrols (CORPAT) for over a decade.
"The CORPAT reflects the shared concerns between the two countries for a peaceful Indian Ocean for the benefit of the international community," the Navy said.
Under the broad ambit of this strategic partnership, Indonesian Navy (TNI-AL) and the Indian Navy have been carrying out coordinated patrolling twice a year since 2002.
