INS Kora suffered minor damage when it was scraped by a merchant vessel off the Visakhapatnam coast, the Indian Navy said in a statement Friday.
The navy said there has been no damage to the watertight integrity of the ship or any injuries or loss of life.
INS Kora was scraped by the merchant vessel Madelieine Rickmers in the wee hours of Friday, nearly 300 nautical miles off the Visakhapatnam coast.
INS Kora, accompanied by INS Gaj, was on a passage from Visakhapatnam to Port Blair.
"INS Kora has reported minor damages to her ships' side. There has been no damage to the watertight integrity of the ship or any injuries or loss of life," the navy said.
A Board of Inquiry (BoI) is being constituted by the Eastern Naval Command to investigate into the circumstances leading to the incident, it added.
