Indian Navy signs pact with Hindustan Shipyard for making 2 Diving Support Vessels



Indian Navy signs contract with Hindustan Shipyard Ltd for construction of 2 Diving Support Vessels: Details, Features, Purpose, Highlights

Indian Navy has signed the contract with Hindustan Shipyard Limited (HSL) situated in Visakhapatnam for construction of 2 Diving Support Vessels (DSV).

Diving Support Vessels (DSV) will help to augment Indian Navy’s submarine support operations on either coast.

The first Diving Support Vessels (DSV) will be built over a 36 month period and will be followed by the second, six months later. These vessels will be based at Vishakhapatnam and Mumbai respectively.

Both the Diving Support Vessels will be of 118 m in length and shall have approximately 7,650 tonnes displacement capacity.

These DSVs will be equipped with Deep Submergence Rescue Vessel (DSRV), which significantly enhances its Submarine Rescue Capabilities. These vessels are capable of effecting submarine rescue upto depths of 650 meters.


Indian Navy undertakes diving operations in the Indian Ocean Region (IOR) in addition to operating submarines to secure our waters. This necessitates extensive diving operations to facilitate various activities such as submarine rescue, testing or salvage, underwater inspection and recovery of objects/ship aircraft lost at sea.

As these activities involve diving operations with divers remaining underwater for prolonged durations, it requires a suitable platform for their launch and recovery, as well as for carriage of related tools and equipment. Thus, induction of DSVs equipped with DSRV, will go long way in enhancing the Indian Navy’s capability and reach of submarine rescue operations in IOR.
