In new indications that the Indian Navy will possibly expedite its long delayed procurement of one or more deep submergence rescue vehicles (DSRVs), it has now invited information from shipbuilders, both local and global, to support the procurement of two new 3000-ton diving support vessels. The Navy wants both ships built with 400-sqm deck space for a "DSRV and associated gear". The ships will also need a helo deck (without a hangar), suitable accommodation for DSRV kit operators, integral boats, diving bells (for rescues upto 300-m) for 2-3 men with a moon pool and, of course, recompression chambers.
The Indian Navy's attempt to buy two DSRVs was cancelled in 2005 following charges of corruption, though the effort has finally picked up again. The Indian Navy has a submarine rescue agreement with the US Navy (air-deployed DSRV kit in 48 hours), on which it would be wholly dependent if an Indian submarine were ever in distress.
