GRSE Delivers India "largest-ever" Survey Vessel to Navy

A notable aspect of this achievement is the significant indigenous content, constituting over 80% of the total cost of the Sandhayak. This delivery underscores the commitment of the Government of India and the Indian Navy to the "Aatma Nirbhar Bharat" (self-reliant India) initiative. Despite challenges posed by the COVID-19 pandemic and other geopolitical factors during its construction, the successful induction of the Sandhayak reflects the collaborative efforts of various stakeholders, including Micro, Small, and Medium Enterprises (MSMEs), and the broader Indian industry. This collective endeavor significantly enhances the maritime capabilities of the nation in the strategically important Indian Ocean Region.

The journey of the Sandhayak began with the laying of its keel on March 12, 2019, followed by its launch on December 5, 2021. Subsequently, the vessel underwent a rigorous series of trials both in harbor and at sea as part of a well-structured schedule. These trials concluded successfully, leading to the official delivery of the ship to the Indian Navy on December 4, 2023.

In addition to their primary surveying functions, these ships have secondary roles, serving limited defense functions and having the capability to operate as hospital ships during times of war or emergencies. The Sandhayak, with a displacement of around 3400 tons and an overall length of 110 meters, boasts cutting-edge hydrographic equipment, including a Data Acquisition and Processing System, Autonomous Underwater Vehicle, Remotely Operated Vehicle, DGPS Long-Range Positioning Systems, and Digital Side Scan Sonar. Propelled by two Diesel Engines, the ship is capable of achieving speeds exceeding 18 knots.

Manufactured by M/s Garden Reach Shipbuilders & Engineers in Kolkata, these Survey Vessel (Large) ships adhere to the regulations set by the Indian Register of Shipping Classification society. Tailored for extensive coastal and deep-water hydrographic surveys, with a focus on port and harbor approaches, as well as the determination of navigational channels and routes, these vessels operate within maritime limits up to the Exclusive Economic Zone (EEZ) and the extended continental shelf. Additionally, they are equipped to gather oceanographic and geophysical data for both defense and civilian applications.

On the 4th of December 2023, a significant milestone was achieved as the Indian Navy officially received the inaugural vessel, Sandhayak (Yard 3025), from Garden Reach Shipbuilders & Engineers (GRSE) in Kolkata. This event marked the completion of the construction of the first of four Survey Vessel (Large) ships, following the formal signing of the construction contract on October 30, 2018.
