GRSE Signs ₹1,032-Crore ONGC Contract for Four Hybrid Offshore Supply Vessels

Summary

Garden Reach Shipbuilders & Engineers (GRSE) has signed a contract with Oil and Natural Gas Corporation (ONGC) to build four hybrid platform supply vessels under a ₹1,032.07-crore order awarded in July 2026. The vessels will feature electrically driven azimuth thrusters and lithium-ion battery energy storage for offshore exploration and production support. The programme, scheduled for completion within 48 months of the award, forms part of GRSE’s expansion into specialised commercial shipbuilding.

GRSE Advances Four-Vessel ONGC Programme

Garden Reach Shipbuilders & Engineers (GRSE) has signed a contract with Oil and Natural Gas Corporation (ONGC) for the construction of four hybrid platform supply vessels (PSVs), advancing a procurement programme initiated in July 2026.

The agreement was signed on October 15 by Commander Shantanu Bose, Director (Shipbuilding) at GRSE, and Ratnesh Kumar, Executive Director (Strategy) at ONGC.

GRSE received the Notification of Award on July 30, 2026. According to the company’s exchange disclosure, the contract is valued at ₹1,032.07 crore, including GST, with completion stipulated within 48 months of the award date.

The project adds four specialised offshore support vessels to GRSE’s commercial shipbuilding portfolio. The latest agreement formalises the existing award and does not represent a separate order.

Vessel Specifications and Offshore Applications

The four platform supply vessels will measure approximately 80 metres in length and 20 metres in breadth, with around 650 square metres of clear deck area. They will be designed and constructed in accordance with Indian Register of Shipping rules.

The vessels are intended to support offshore exploration and production activities, including the transportation of equipment and supplies to offshore installations. Their operational requirements will include cargo-handling capability, dependable onboard power and the ability to manoeuvre and maintain position in demanding offshore conditions.

The integration of propulsion equipment, electrical systems, cargo arrangements and vessel controls will be central to meeting these requirements.

Battery-Integrated Propulsion System

The vessels will combine electrically driven azimuth thrusters with lithium-ion battery energy storage. GRSE has identified peak-load management, spinning reserve, dynamic positioning support and emergency response as intended applications for the battery system.

Battery storage can help manage fluctuations in onboard electrical demand and provide additional power capacity when required. In dynamic positioning operations, the propulsion and control systems work together to maintain a vessel’s position against environmental forces.

The system’s overall efficiency will depend on its final configuration, operating profile and machinery-management strategy. However, GRSE’s available announcement does not specify projected fuel savings or reductions in greenhouse gas emissions.

Any assessment of these benefits will require operating data and a defined baseline against which energy consumption and emissions can be compared.

Earlier Initiatives Support GRSE’s Commercial Shipbuilding Expansion

GRSE’s pursuit of offshore and specialised commercial vessel projects predates the ONGC contract.

At Nor-Shipping in June 2025, the company signed an agreement with Dubai-based Aries Marine to explore opportunities involving offshore platform and vessel design. The arrangement envisaged identifying potential offshore projects using Aries designs for construction by GRSE. The agreement established a framework for commercial cooperation, but does not establish the specific design arrangements for the ONGC vessels.

During the same event, GRSE announced a memorandum of intent with Germany’s Carsten Rehder for four additional 7,500-deadweight-tonne multipurpose vessels featuring hybrid propulsion.

These initiatives indicated the shipbuilder’s interest in broadening its commercial vessel portfolio and developing capabilities in alternative propulsion technologies.

GRSE Expands Technical Cooperation Through Industry Partnerships

In September 2026, GRSE entered into further cooperation arrangements at SMM Hamburg.

An agreement with DNV covered potential collaboration in specialised vessels, sustainable technologies, digital shipbuilding and skills development.

Separately, GRSE signed an arrangement with Damen Technical Cooperation to explore dredger design and construction opportunities for Indian customers. The vessel categories covered included trailing suction hopper dredgers and water injection dredgers.

These partnerships address market segments beyond offshore supply vessels. They provide frameworks for technical cooperation and capability development, although they should be distinguished from confirmed vessel construction contracts.

Construction and Delivery Will Determine Project Outcomes

The ONGC programme will require GRSE to complete detailed engineering, equipment procurement, construction, system integration and vessel trials within the stipulated timeframe.

For ONGC, the vessels will add specialised maritime support capacity for offshore exploration and production operations. For GRSE, the series will test its ability to deliver multiple hybrid-powered offshore vessels with integrated electrical and propulsion systems.

Construction progress, delivery schedules and operational performance will determine the programme’s longer-term commercial significance. The vessels’ performance in service may also provide a reference point for future offshore support vessel projects, particularly those incorporating battery-assisted propulsion.
