The GRSE ONGC PSV contract brings four Platform Supply Vessels to Garden Reach Shipbuilders and Engineers, after Oil and Natural Gas Corporation Limited issued a Notification of Award covering the vessels' design, construction and delivery. GRSE is a Navratna Defence Public Sector Undertaking under the Ministry of Defence, and it confirmed the order is worth Rs 1,032 crore.

The Notification of Award reached the Kolkata shipyard from Oil and Natural Gas Corporation on 30 July 2026.

The specifications behind the GRSE ONGC PSV contract

Each vessel will be built to the rules of the Indian Register of Shipping, with an overall length of about 80 metres and a beam of 20 metres. Deadweight capacity comes in at 3,000 tonnes, endurance is rated at 45 days plus a further three, and the clear deck area runs to roughly 650 square metres.

The four vessels will support offshore exploration and production work across ONGC's operating areas.

A hybrid propulsion package built around batteries

GRSE has built the design around an advanced hybrid propulsion architecture, pairing electrically driven azimuth thrusters with a Lithium-Ion Battery Energy Storage System. The battery bank is sized to support peak load management and spinning reserve, giving the vessel headroom that a conventional diesel-only plant would not carry at the same fuel burn.

Dynamic positioning and emergency backup

The same battery system also backs dynamic positioning and carries a reserve for emergency response if primary power is lost.

GRSE's move into the offshore energy market

The GRSE ONGC PSV contract marks the yard's move beyond warships and patrol craft into the commercial and offshore vessel market, a segment GRSE has flagged as a growth area since it moved up to Navratna status last month. That elevation came with a record Rs 7,002 crore in FY26 revenue and Rs 748 crore in profit, alongside a full order book of naval and export platforms.

GRSE is not the only defence shipyard chasing work outside the Navy's own orderbook. Cochin Shipyard has run a similar commercial and naval mix through its Kochi yards this year.

Six decades of shipbuilding behind the order

GRSE traces its own history back to 1884, when it began as a small workshop repairing vessels for the River Steam Navigation Company on the Hooghly. The Government of India took it over in 1960, and the yard went on to become the first in independent India to build a warship for the Navy, the Seaward Defence Boat INS Ajay, in 1961.

The export side of the business dates back almost as far. GRSE built the CGS Barracuda patrol vessel for Mauritius, the fast patrol vessel SCG PS Zoroaster for Seychelles, and the cargo and passenger ferry MV Ma Lisha for Guyana. Its most recent naval deliveries included the Project 17A frigate Dunagiri, the survey vessel Sanshodhak and the anti-submarine warfare craft Agray, all commissioned at Kolkata on the same day in June.

Across more than 800 platforms delivered, including 118 warships for the Navy, the Coast Guard and friendly foreign countries, GRSE says it can now run concurrent construction of up to 28 ships across its four yards.
