GRSE-class survey vessel

The GRSE-class survey vessels are a series of four survey vessels planned to be built by Garden Reach Shipbuilders and Engineers (GRSE), Kolkata for the Indian Navy. The first vessel is expected to be commissioned by 2021. The primary role of the vessels would be to conduct coastal and deep-water hydro-graphic survey of ports, navigational channels, Economic Exclusive Zones and collection of oceanographic data for defence. Their secondary role would be to perform search & rescue, ocean research and function as hospital ships for casualties.[1][2][3][4]
