Indigenous diving support vessel Nipun

One line

The Navy prepared to commission INS Nipun, the second indigenous diving support vessel.

Summary

Diving support vessels enable deep-sea diving, underwater repair, rescue support, and sustained operations. Indigenous construction develops naval design, shipbuilding, systems integration, and maintenance capability.

PYQ pattern

UPSC may connect naval support assets with underwater infrastructure, submarine rescue, shipbuilding, and maritime security.

Core notes

Diving support vessels provide platforms, equipment, medical support, and control for underwater operations.
Saturation diving allows divers to work at depth for extended periods under controlled pressure.
Dynamic positioning helps a vessel maintain position during underwater work.
Commissioning marks entry into naval service after construction and trials.

Prelims lens
