Commissioned on August 14, 1985, INS Nirupak played a pivotal role in hydrographic surveys, significantly contributing to navigational safety and scientific understanding of oceanography in the Indian Ocean Region. The ship was also actively involved in humanitarian assistance and disaster relief operations, notably during the 2004 Tsunami Relief (Operation Gambhir), where it provided critical support as a hospital ship to Indonesia
Throughout its service, INS Nirupak was recognized for its excellence, receiving the Admiral Jal Cursetji Rolling Trophy for the best survey ship multiple times.
