Mazagon Dock Shipbuilders Ltd signed an agreement on 18 September 2026 with National Shipbuilding and Heavy Industries Park-AP to act as the anchor shipyard for a mega greenfield shipbuilding cluster at Dugarajapatnam in Tirupati district. The Mumbai based defence shipyard plans to invest about ₹15000 crore over five to seven years to build a commercial yard with an initial capacity of 1.2 million gross tonnage a year. The project, expected to create about 45000 direct and indirect jobs, is the centrepiece of Andhra Pradesh’s plan to become a major shipbuilding hub on the east coast.
What Did Mazagon Dock Agree to Build at Dugarajapatnam?
Mazagon Dock Shipbuilders Ltd will develop a modern commercial shipyard at Dugarajapatnam as the anchor unit of the proposed shipbuilding cum port cluster. An anchor shipyard means the lead company that builds the core yard and attracts smaller suppliers, design firms and repair units around it. The memorandum of understanding for this role was signed in Amaravati on 18 September 2026 between Mazagon Dock Shipbuilders and National Shipbuilding and Heavy Industries Park-AP (NSHIP-AP).
NSHIP-AP is a special purpose vehicle jointly formed by the Andhra Pradesh Maritime Board (APMB) and the Visakhapatnam Port Authority (VPA). Visakhapatnam Port Authority holds a 50 percent share in the vehicle and will provide technical support and coordination with central agencies. The Andhra Pradesh Maritime Board will arrange land, supporting infrastructure and statutory clearances for timely execution.
The proposed yard will start with a design capacity of 1.2 million gross tonnage (GT) a year. Gross tonnage is a standard measure of the internal volume of a ship and is used to describe shipyard capacity. The yard will build tankers, bulk carriers, container ships, LNG carriers and other large specialised vessels. Mazagon Dock Shipbuilders has said the capacity can be expanded later based on market demand, and the investment will proceed only after required approvals and clearances are received.
Dugarajapatnam Port in Which District?
Dugarajapatnam port is located in Vakadu mandal of Tirupati district in southern Andhra Pradesh, close to the Tamil Nadu border and the Pulicat Lake region. The greenfield port and shipbuilding cluster site spreads across coastal villages in Tirupati district with a small portion extending into Nellore district.
Dugarajapatnam is a coastal village on the Bay of Bengal in Tirupati district, which was formed in 2022 after the reorganisation of Chittoor and Nellore districts. The project land of 2170.7 acres has been identified mainly in Vakadu mandal villages such as Pathetipalem, Vagarru, Valamedu and Pamanji, with a smaller parcel in Kota mandal of Nellore district. In February 2026 the state government sanctioned ₹544.3 crore to acquire this land through the Andhra Pradesh Maritime Board.
The site was chosen for natural and strategic reasons. Dugarajapatnam offers a draft of about 14 metres, which means the depth of water available for ships is higher than the 10 metres available at alternative sites like Machilipatnam and Bhavanapadu. A deeper draft allows larger vessels such as bulk carriers and LNG carriers to enter safely. The full cluster covers about 3488 acres with nearly 2.1 km of waterfront, which provides space for berths, dry docks, outfitting jetties and repair facilities along with ancillary industries.
What Is Shipbuilding and What Is a Greenfield Shipyard?
Shipbuilding is the process of designing, constructing and repairing ships and other large sea going vessels inside specialised facilities called shipyards. The shipbuilding industry includes shipyards and their suppliers of steel, engines, design services, outfitting and repair, and it supports shipping, trade, ports and naval strength.
A shipbuilding cluster is a planned industrial zone where a large shipyard operates together with component makers, steel processors, logistics firms and skill centres in one location. This sharing of land, power, water, roads and testing facilities lowers cost and speeds up production. A greenfield shipyard means a completely new yard built on unused land, while a brownfield yard means expansion or modernisation of an existing yard.
Outfitting is the stage where engines, electrical systems, navigation tools, cabins and safety equipment are fitted into the hull of a ship after the steel structure is ready. Distributed shipbuilding is a method where different blocks or parts of a ship are built at separate yards and then assembled at one place. The Dugarajapatnam proposal is a mega greenfield cluster because it combines a new anchor yard, a new port and a full supplier ecosystem on a large coastal site.
Is Mazagon Dock a Government Company?
Yes, Mazagon Dock Shipbuilders Ltd is a government company. It is a Navratna Central Public Sector Enterprise under the Ministry of Defence, headquartered in Mumbai. The central government owns a majority stake in the listed company, which builds warships and submarines for the Indian Navy and Coast Guard.
Mazagon Dock Shipbuilders, often shortened to MDL or Mazdock, traces its roots to ship repair yards of the 18th century in Mumbai. The company was registered as a private firm in 1934 and was taken over by the Government of India in 1960. It was granted Mini Ratna Category I status in 2006 and Navratna status on 25 June 2024, which gives it greater financial freedom to invest and form joint ventures. The company was listed on the BSE and NSE in October 2020.
The yard is known for complex defence construction. It has delivered more than 800 vessels, including destroyers, stealth frigates, missile boats and Scorpene class submarines. Recent deliveries include the first stealth frigate of Project 17A, Nilgiri, and the fourth destroyer of Project 15B, Surat. Mazagon Dock Shipbuilders operates main facilities at Mazgaon in Mumbai and at Nhava, and it builds vessels up to 30000 deadweight tonnage. Deadweight tonnage is the total weight a ship can safely carry, including cargo, fuel and crew.
Mazagon Dock vs Cochin Shipyard: Which Is Better?
Neither yard is strictly better, as both serve different primary roles within Indian shipbuilding. Mazagon Dock Shipbuilders specialises in warships and submarines for naval combat, while Cochin Shipyard handles a wider mix of commercial vessels, ship repair and naval platforms including an aircraft carrier.
| Feature | Mazagon Dock Shipbuilders | Cochin Shipyard |
|---|---|---|
| Ownership and ministry | Central public sector unit under the Ministry of Defence | Central public sector unit under the Ministry of Ports, Shipping and Waterways |
| Headquarters | Mumbai, Maharashtra | Kochi, Kerala |
| Origin | Registered in 1934, nationalised in 1960 | Incorporated in 1972 as a greenfield yard at Kochi |
| Core strength | Destroyers, stealth frigates, submarines and Coast Guard patrol vessels | Large commercial ships, bulk carriers, dredgers, ship repair and aircraft carrier construction |
| Flagship delivery | Scorpene submarines, Nilgiri frigate and Surat destroyer | INS Vikrant, India’s first indigenously built aircraft carrier |
| Commercial shift | Now entering large commercial shipbuilding through Dugarajapatnam and Dighi projects | Already active in commercial orders from Indian and European owners |
As of 30 June 2026, Mazagon Dock Shipbuilders reported an order book of about ₹18218 crore, driven mainly by naval programmes. In the April to June 2026 quarter the company posted a consolidated net profit of about ₹550 crore on revenue of about ₹2943 crore. The Dugarajapatnam move marks a shift from purely defence work to high volume commercial construction, which will place Mazagon Dock Shipbuilders in more direct comparison with Cochin Shipyard in the merchant vessel segment.
Policy Context: Maritime India Vision and Shipbuilding Schemes
The Dugarajapatnam cluster is being developed under the Shipbuilding Development Scheme (SbDS) of the Ministry of Ports, Shipping and Waterways. The scheme supports new greenfield clusters, modernisation of existing brownfield yards and creation of an India Ship Technology Centre for design and skills. The Andhra Pradesh government has positioned the project within the national roadmaps of Maritime India Vision 2030 and Maritime Amrit Kaal Vision 2047.
Maritime India Vision 2030 aims to lift India into the top ten shipbuilding nations from a rank beyond twenty. Maritime Amrit Kaal Vision 2047 sets a higher goal of entering the top five by 2047 with annual output of 4.5 million gross tonnage, up from the current level of about 0.01 million gross tonnage. The vision also targets handling of 1300 million tonnes per annum of coastal cargo and greater use of Indian built ships for overseas trade.
In September 2025 the central government approved a combined package of about ₹69725 crore for shipbuilding and maritime finance. Operational guidelines for the two core building schemes were notified in December 2025.
| Scheme | Outlay | Purpose |
|---|---|---|
| Shipbuilding Financial Assistance Scheme (SBFAS) | ₹24736 crore | Direct support of 15 to 25 percent per vessel, graded by vessel type, with stage wise payment and support for series orders |
| Shipbuilding Development Scheme (SbDS) | ₹19989 crore | Capital support for greenfield clusters and brownfield expansion, risk cover and technology centre |
| Maritime Development Fund (MDF) | ₹25000 crore | Long term equity and interest support for maritime projects, including a Maritime Investment Fund of ₹20000 crore |
Both SBFAS and SbDS are valid for contracts signed from 24 September 2025 to 31 March 2036, with an extension envisaged up to 2047. Large shipbuilding projects have also been granted infrastructure status to access long tenure finance, while public orders up to ₹200 crore are reserved for Indian yards and Indian built ships get priority through the Right of First Refusal system.
The centre’s framework envisages broadly one greenfield cluster per state. In principle approval has been given for five sites across Gujarat, Maharashtra, Andhra Pradesh, Odisha and Tamil Nadu. Mazagon Dock Shipbuilders had earlier signed an agreement in September 2025 to explore a yard at Thoothukudi in Tamil Nadu, but Tamil Nadu later moved ahead with HD Korea Shipbuilding and Offshore Engineering as anchor. Mazagon Dock Shipbuilders then finalised two anchor roles in September 2026, one at Dugarajapatnam in Andhra Pradesh and another at Dighi in Maharashtra, each planned for 1.2 million gross tonnage.
Strategic and Economic Impact for Andhra Pradesh and India
The techno economic feasibility report places the Dugarajapatnam shipbuilding and repair yard at about ₹29254 crore and the adjoining greenfield port at about ₹9513 crore. Under the approved funding pattern, the government will provide about ₹5289 crore for land and marine works, while the anchor investor will invest about ₹23964 crore in the core yard. The state government is also expected to invest about ₹2000 crore in supporting roads, power, water and housing.
For Andhra Pradesh, the project uses the state’s 1053 km coastline, the second longest on the east coast, to create a manufacturing hub beyond ports and fishing harbours. The yard is expected to trigger ancillary units in marine engineering, steel fabrication, engines, paints, logistics and ship repair at nearby centres in Nellore, Krishna, Bapatla, Kakinada and Srikakulam. This local supplier base can cut dependence on imports and keep more shipbuilding value within India under the Make in India effort.
For India, the stakes are global. At present, most large commercial ships are built in China, South Korea and Japan, while Indian yards focus mainly on defence and small vessels. A 1.2 million gross tonnage commercial yard on the Bay of Bengal gives India scale to bid for tankers, container ships and gas carriers for both Indian and foreign owners. It also strengthens maritime security by preserving domestic capacity to build and repair large vessels close to key eastern sea lanes.
