It has a large computer-aided design (CAD) centre for ship modelling and design. There are four workshops for plate preparation and steel fabrication.

GRSE has a dry dock for ships up to . It has a building berth and two slipways for hull construction. It has a covered all-weather non-tidal wet basin for fitting-out medium and small ships and another fitting-out complex for ships with three berths alongside. In addition, it has two river jetties for berthing smaller vessels up to 60 m in length. GRSE has engine assemble, test, repair, and overhaul facilities in Ranchi, which acquires 62 acres of land.

GRSE and Syama Prasad Mookerjee Port, Kolkata (SMPK) have inked a long-term concession agreement for GRSE to operate 3 dry docks. Here, GRSE undertakes multiple dry dock repairs of ships up to 160 m length, 20 m beam, and 7 m draught. These docks are situated inside a wet basin, which allows for docking and undocking operations independent of river tidal requirements. The wet basin also has multiple berthing facilities for afloat maintenance and refit operations.

On 1 July 2006, GRSE acquired the loss-making Rajabagan Dockyard (RBD) of Central Inland Water Transport Corporation (CIWTC). RBD's facilities with its 600 m waterfront helped alleviate some of GRSE's space constraints and increase its production capacity.

As of 2011, the shipyard was undergoing a upgrade programme, expected to be completed by March 2012. The second phase of the upgrade programme was scheduled to commence from June 2013.

On 30 January 2024, GRSE signed a Frame and Individual License Agreement with Rolls-Royce Solutions, Germany, to cooperate in the license production and localisation of the MTU IMO Tier II compliant Series 4000 Marine Engines for governmental ships. The agreement enabled GRSE to manufacture the engines in its Diesel Engine Plant in Ranchi. The engines can power warships of fast patrol vessel, interceptor boat and fast attack craft class ships of the Indian Navy and the Indian Coast Guard. It is already deployed on the Car Nicobar-class patrol vessel. The series of engines have power output range of 746-4300 kW. The agreement includes transfer of technology for engine assembly, painting, parts sourcing, and after-sales service for these engines. On 28 January 2023, a Memorandum of Understanding (MoU) was also signed for the same purpose.
