The Indian Navy is poised to achieve a significant milestone with the commissioning of the first ship of the Survey Vessel Large Project, INS Sandhayak, on February 3, 2024. Designed and constructed indigenously by Garden Reach Shipbuilders and Engineers (GRSE), INS Sandhayak represents a triumph of indigenous shipbuilding capabilities and a major stride in enhancing the country’s maritime prowess.

The Survey Vessel Large Project heralds a new era in coastal and deep-water hydrographic survey capabilities for the Indian Navy. These survey ships, exemplified by INS Sandhayak, are equipped to conduct comprehensive hydrographic surveys of ports, harbor approaches, and navigational channels. Beyond traditional survey duties, they are also proficient in surveying maritime limits and collecting vital oceanographic and geographical data crucial for defense applications.

Powered by two Marine Diesel Engines and propelled by Fixed Pitch Propellers, these vessels boast Bow and Stern Thrusters, facilitating precise maneuverability even at low speeds during survey operations. Moreover, their versatility extends to secondary roles such as Search and Rescue missions, Disaster Relief operations, and emergency medical assistance, with provisions for limited hospital facilities.

A notable feature of the survey vessels is the inclusion of a retractable hangar, designed to accommodate a utility helicopter, enhancing their operational flexibility and aerial reconnaissance capabilities.

The contract for the construction of four survey ships was inked between the Ministry of Defence and GRSE on October 30, 2018, amounting to a total cost of Rs 2,435 crore. These vessels, meticulously designed by GRSE’s proficient team, are tailored to meet the exacting standards of the Indian Navy, adhering to the principles of ‘Integrated Construction’ and in compliance with classification society regulations.

With over 80 percent indigenous content by cost, the Survey Vessel Large Project underscores India’s commitment to self-reliance in defense production. By leveraging domestic manufacturing capabilities, the project not only bolsters the country’s maritime defense infrastructure but also fosters economic growth and job creation within the indigenous defense manufacturing ecosystem.
