For decades, India’s maritime headlines have been dominated by grand shipbuilding contracts, launch ceremonies, and indigenous warship milestones. But quietly, an equally strategic and potentially more lucrative segment is coming into sharp focus: ship repair and maintenance, or maritime MRO (Maintenance, Repair, and Overhaul).
While new ship orders make for splashy news, repair and refit work is steadier, less cyclical, and – when done right – highly profitable. And now, with the government’s push for self-reliance under Aatmanirbhar Bharat, this niche is poised for accelerated growth.
In fact, three listed public-sector shipbuilders – Mazagon Dock Shipbuilders Ltd, Garden Reach Shipbuilders & Engineers (GRSE), and Cochin Shipyard Ltd – are positioning themselves to capture a disproportionately large share of this emerging market.
Why Ship Repair is the Next Maritime Growth Story
India’s shipbuilding sector has made giant strides in capability, especially in defence. Every ship for the Indian Navy and Indian Coast Guard is now built in Indian yards, and under-construction warships are on track to achieve almost 100% indigenous content by the end of this decade.
That means the supply chain – from steel plates to electronics – is firmly rooted in India. The only missing link – A robust domestic MRO ecosystem.
Historically, a significant chunk of India’s repair and maintenance needs – especially for commercial vessels – was met abroad, in yards in Dubai, Singapore, or Colombo. This created longer downtimes, valuable foreign exchange outflow, and dependency on foreign infrastructure.
Now, policy and investment are aligning to change that. Recent drivers include:
- Policy Tailwinds: Maritime India Vision 2030, Maritime Amrit Kaal Vision, Defence Production and Export Promotion Policy, and the upcoming Defence Procurement Manual 2025 all emphasize domestic repair capability.
- Strategic Necessity: Shorter turnaround times for warships and coast guard vessels are critical for operational readiness.
- Commercial Opportunity: The global ship repair market is growing, driven by rising fleet sizes, stricter environmental retrofitting requirements, and MRO outsourcing.
- Infrastructure Expansion: Several new dry docks, ship lifts, and dedicated repair facilities are in the pipeline.
The government’s maritime push mirrors similar moves in the aviation sector – such as the opening of Safran’s massive engine MRO in Hyderabad – underlining a larger strategy to make India a regional MRO hub.
Recent Industry Momentum
- India-Japan-Maldives Maritime Collaboration: In March 2024, India held maritime dialogues with Japan and the Maldives, including discussions on technical cooperation in ship repair and refit to improve sea-lane security.
- Private Sector Interest: Adani Ports recently announced plans to explore a dedicated ship repair facility alongside its port assets, expanding beyond just cargo handling.
- Naval and Coast Guard Contracts: In FY24-25, the Indian Navy floated multiple tenders for refits of patrol vessels and corvettes, signalling a strong pipeline for domestic yards.
- Carbon Compliance Retrofits: With IMO’s decarbonisation regulations tightening from 2025, a wave of retrofitting work – from hull modifications to fuel system upgrades – is expected to hit repair yards.
3 Listed Stocks Positioned for the Ship Repair Boom
- Mazagon Dock Shipbuilders (MDL) – Expanding Capacity, Going Global
Traditionally India’s premier warship and submarine builder, MDL is doubling down on ship repair – a segment that already accounts for almost half its current revenues.
- Domestic Strength: Three dry docks and three wet basins in Mumbai, plus dedicated submarine maintenance docks.
- Expansion Underway: Development of the Nhava Yard and newly acquired MbPA land, ₹10 billion investment, to be completed in 2-3 years.
- Global Play: Acquisition of Colombo Dockyard, with plans to grow revenue from ₹10 billion to ₹15 billion in FY25, targeting international clients.
- Defence Pipeline: Bids for four Indian Coast Guard refit projects, including offshore and fast patrol vessels.
Why it matters: MDL is leveraging its defence credibility to grab a bigger commercial market share both domestically and in South Asia – while boosting capacity for larger vessels.
- Garden Reach Shipbuilders & Engineers (GRSE) – Refit Specialist With Explosive Growth
GRSE runs a dedicated ship repair vertical, offering comprehensive MRO services from dry docking to complex systems overhauls.
- Revenue Growth: Its ship repair revenues have surged 6x in three years – from ₹190 million in FY22 to ₹1.1 billion in FY25E.
- Defence Focused: Strong refit order book worth ₹1.7 billion for FY25, mainly for Navy and Coast Guard vessels.
- Support Capability: Provides in-service support across the Indian Ocean Region, ensuring fleet readiness.
- Market Potential: Estimates the global ship repair market to reach ₹150 billion over the next five years, and is positioning itself as a key regional player.
Why it matters: GRSE’s smaller base and rapid growth rate give it room for further acceleration, particularly with more annual maintenance contracts in the pipeline.
- Cochin Shipyard Ltd (CSL) – The Incumbent Leader With ₹15 Billion Order Book
CSL is India’s largest public sector yard by capacity and has long been active in ship repairs, both domestic and foreign. Now, it’s scaling up massively.
- ISRF Advantage: The International Ship Repair Facility can handle 82 ships annually. Already 14 are under repair. Expected to generate ₹2.5 billion in revenues in its first two years, rising to ₹6 billion at peak.
- Dry Dock Power: New 310m dry dock operational, doubling as a repair asset.
- Big Contracts: Master Ship Repair Agreements with Maersk and the US Navy.
- Order Book: Repair orders worth around ₹15 billion, with FY26 revenue expected to match that.
Why it matters: CSL has the infrastructure, scale, and global client base to cement itself as the go-to Indian hub for high-value, quick-turnaround repairs.

| Company | Existing P/E | 5-Year Median P/E | Industry P/E | Takeaway |
|---|---|---|---|---|
| Mazagon Dock | 43.0 | 21.7 | 43.0 | In line with peers; capacity expansion could justify valuations |
| Garden Reach | 45.4 | 27.5 | 61.5 | Trading at a discount to industry; fast revenue growth a plus |
| Cochin Shipyard | 56.2 | 24.9 | 43.0 | Commands a premium; largest capacity and global contracts |

Why Execution Matters More Than Orders
It’s tempting to focus solely on the order books, but for ship repair, the real driver is execution efficiency. Unlike shipbuilding projects that span years, repairs typically run from weeks to months – delays directly eat into capacity utilisation and margins.
With all three companies trading above their historical median P/E ratios, investors are already pricing in growth. The market is watching for:
- Timely completion of ongoing infra projects (Nhava Yard for MDL, full ISRF ramp-up for CSL)
- Winning and renewing global repair contracts
- Capability to handle complex retrofitting for environmental compliance
- Securing recurring maintenance deals with navies and private shipping lines
The Bigger Picture: India as a Regional MRO Hub
The global ship repair market is projected to expand steadily, driven by:
- Merchant fleet growth in the Asia-Pacific region
- The need for retrofits to meet IMO decarbonisation requirements
- Ageing naval assets requiring lifecycle extensions
India – strategically located on busy east-west shipping routes, with low labour costs and growing technical expertise is well placed to capture a chunk of this market.
If policy support continues and execution matches ambition, India could replicate its aviation MRO model in the maritime space, attracting regional clients from the Middle East, Africa, and Southeast Asia.
Conclusion
The narrative in India’s maritime sector is shifting from launching new ships to keeping them mission ready. Ship repair might lack the glamour of christening a new vessel, but it offers recurring revenues, high margins, and strategic importance.
With strong order visibility, expanding infrastructure, and government backing, Mazagon Dock, GRSE, and Cochin Shipyard are the three names to watch as India builds its standing as a global ship repair hub.
