Commercial vessels
Among commercial and scientific ships, GRSE builds oceanographic and hydrographic research vessels, marine acoustic research ships, non-propelled dredgers, grab hopper dredgers, trailing suction hopper dredgers, tugboats, and bulk carriers.
On 16 July 2024, GRSE signed a contract with the National Centre for Polar and Ocean Research (NCPOR), Ministry of Earth Sciences, Government of India, for construction of an advanced Ocean Research Vessel (ORV).[19]
On 29 October 2024, the Naval Physical and Oceanographic Laboratory (NPOL), an organization under the DRDO, placed an order for a new Acoustic Research Ship (ARS) with the Garden Reach Shipbuilders & Engineers, Kolkata. The order worth inr 4909800000 was signed in Kochi. The ARS will have an overall length of 90 m and a beam of 14 m. It will be able to achieve speeds ranging up to 12 kn. The ship will have a minimum endurance of 30 days or 4500 nmi. It will have a complement of 70 personnel. The vessel will have diesel-electric propulsion and 3 deck cranes will be fitted on board to handle research equipment. The ARS will be able to deploy, tow, and retrieve a variety of equipment, including acoustic modules; conduct high-resolution surveys of sound velocity profiles in time and/or space; and gather data on ocean tides and currents for use in survey optimisation, underwater mooring design, and offshore deployments. Additionally, it will be able to launch, moor, and maintain independent sonobuoys as well as gather data from them. The ship will be able to conduct acoustic system experiments at various speed regimes while remaining silent due to its broad speed range. The ARS will also be equipped with a dynamic positioning system that will enable it to hold its place until Sea State 4.[19] The keel laying of the ship was conducted on 15 October 2025, with delivery expected in 2027. Being the first silent-class ship to be built in India, it will be capable of deploying and towing various equipment such as acoustic modules, generating sound velocity profiles, collecting ocean data, underwater moored systems, and other facilities for various sea trials.[20]
On 2 June 2025, GRSE signed a Memorandum of Understanding (MoU) with a Norweign firm Kongsberg in Oslo for the development of India's first Polar Research Vessel (PRV). This is expected to meet the requirements of National Centre for Polar and Ocean Research (NCOPR). In 2023, Union Minister Kiren Rijiju had informed the Rajya Sabha that India's first Polar Research Vessel (PRV) was expected to be developed within five years, at an estimated cost of inr 26000000000.[21][22]
On 11 June 2025, GRSE signed a contract for 2 Coastal Research Vessel (CRV) from the Geological Survey of India. Each CRV will be 64 m long and 12 m wide, with a deadweight tonnage of around 450 tonnes. Built for extended missions, these vessels will feature an endurance of 15 days and a maximum speed of 10 knots. They will be capable of accommodating up to 35 personnel onboard. The vessels — to be equipped with laboratories for data processing and sample analysis — will be capable of multiple roles like geological mapping, mineral exploration, ocean environment monitoring, and scientific research. The vessels will be powered by diesel electric propulsion and will feature a dynamic positioning system for operations in Sea State 3 conditions.[23][24][25]
As of September 2025, the shipyard is constructing 26 commercial vessels, of which nine are meant for export.[26]
Naval vessels
By November 2016, GRSE had delivered 98 ships to the Indian Armed Forces.[7] As of March 2024, GRSE has designed and built 108 warships and patrol vessels for the Indian Navy and the Coast Guard for the last 63 years.[27] Vessels built at GRSE include guided-missile frigates, corvettes, fleet tankers, fast patrol vessels, amphibious warfare vessels and hovercraft.[4] The 100th ship to be built by the shipyard, LCU L-56 from the Mk. IV LCU was delivered to the Indian Navy on 30 March 2019.[28]
It was the first instance on 30 March 2026 when GRSE delivered three warships to the Indian Navy simultaneously. The triplet included INS Sanshodhak, a Sandhayak-class survey vessel; INS Dunagiri (2022), a Nilgiri-class frigate
Exports
GRSE delivered the corvette MCGS Barracuda to Mauritius on 20 December 2014. The contract was worth $58.5 million.[38] The Mauritius offshore patrol vessel has an integrated bridge system and can support 83 member crew. It measures 74.10 m in length and 11.40 m in breadth and will be capable of moving at a maximum speed of 22 kn with an approximate displacement of 1,350 tonnes.
GRSE has been short-listed for a patrol boat project for Vietnam worth inr 6000000000 and is also bidding for an order of two frigates for Philippines.[38][39]
GRSE was reported to be the lowest bidder to supply two light frigates to the Philippines. A total of four firms joined the bidding for the Philippine Navy project: GRSE; Hyundai Heavy Industries Inc. and Daewoo Shipbuilding & Marine Engineering Co. Ltd., both from South Korea; and Navantia S.A. of Spain. GRSE's light frigate would have been a design based on the
