INS Sandhayak, the first of the indigenously designed and constructed Sandhayak Class hydrographic survey ships, has made its maiden port call at Port Klang, Malaysia, from July 16 to 19, 2025. This visit underscores India's commitment to bolstering maritime cooperation and strengthening hydrographic ties with Malaysia and the broader Indo-Pacific region.

The primary objective of INS Sandhayak's visit is to facilitate technical exchanges and fortify institutional connections through collaborative endeavors. These initiatives encompass the sharing of survey technologies and sustained hydrographic support engagements. Key activities during the visit include in-depth knowledge-exchange sessions, official receptions, and events designed to foster international goodwill and elevate awareness of India's MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) vision. The MAHASAGAR vision seeks to boost regional maritime cooperation.

This port call marks the first time an Indian hydrographic vessel has visited Malaysia, highlighting the deepening naval cooperation between the two nations. The ship's engagements with the Royal Malaysian Navy include visits to the National Hydrographic Centre, subject matter expert exchanges, sports interactions, and cross visits by navy personnel. Additionally, the Indian mission in Kuala Lumpur has organized visits for school students and an on-board reception during the ship's stay.

INS Sandhayak, commissioned in February 2024, represents a significant achievement in indigenous shipbuilding under the Atmanirbhar Bharat initiative. As the lead ship of its class, INS Sandhayak is equipped for full-scale coastal and deep-water surveying, as well as oceanographic data collection. It also has the capability to support search and rescue (SAR) and humanitarian operations, with an onboard helicopter and hospital functions.

The visit of INS Sandhayak to Port Klang demonstrates India's growing role in regional hydrographic capacity building, operating under the Indian Naval Hydrographic Department (INHD) and National Hydrographic Office framework. This initiative reaffirms India's commitment to regional maritime cooperation and the sharing of hydrographic expertise. By expanding regional hydrographic capabilities, India positions itself as a trusted partner in maritime safety and development across the Indo-Pacific.

Concurrently with INS Sandhayak's visit, INS Nistar, India's first indigenously designed Diving Support Vessel, was commissioned, further enhancing maritime security and safety in the Indian Ocean Region.
