Visakhapatnam, Andhra Pradesh, India – February 8, 2024 – In a significant stride for India's maritime strength, the Indian Navy has proudly commissioned the advanced survey vessel INS Sandhayak in a grand ceremony in Visakhapatnam. Three more will follow. The vessel is equipped with sophisticated sonar systems from Teledyne Marine and represents the pinnacle of modern naval engineering. The Defense Minister, Rajnath Singh, officiated at the commissioning ceremony on Saturday, February 3, 2024.

The INS Sandhayak, a 110-meter-long ship with a displacement of 3,400 tons, is powered by two diesel engines and can exceed speeds of 18 knots. Built by Garden Reach Shipbuilders & Engineers (GRSE), the vessel is the first to join the Indian Navy's fleet as part of this program.

The commissioning event was graced by VIP guests from the Navy and the Indian Naval Hydrographic Office (NHO), including top-ranked Navy officers from the regional command. The current Chief Hydrographer of India, Vice Admiral Lochan Singh Pathania, and his predecessors were also in attendance to witness this milestone in Indian naval history.

Teledyne Marine, a global leader in underwater technology, has been instrumental in providing a suite of advanced sonar systems. These include 4 HydroSweep DS Deep Water Multibeam Echosounders​ (MBES), 8 SeaBat T-Series Shallow Water Multibeam Echosounders (MBES), and 36 DESO 5 Single Beam Echosounders (SBES).

In collaboration with their local partner, Pan India, Teledyne Marine has been actively engaged in the final installation and preparation for the sea trials of these sonar systems, ensuring they meet the highest quality and performance standards.

The deployment of these state-of-the-art sonar systems is set to significantly bolster the Indian Naval Hydrographic Office's capabilities in surveying, researching, and charting the vast Indian Ocean.
