India Outlines Roadmap for Strategic Independence in Maritime Technology

India’s maritime sector is entering a significant phase of transformation, driven by investments in ports, shipbuilding, ship repair, ship recycling, inland waterways, and maritime infrastructure. However, industry experts indicate that long-term self-reliance cannot be achieved merely by expanding shipyard capacity or building more vessels. True maritime independence requires India to design, build, equip, operate, and maintain ships using technologies and equipment developed substantially within the country.

The strategic objective is to ensure that Indian cargo is increasingly carried by Indian ships, operated by Indian crews, and supported by domestic technology and equipment. Achieving this transformation would retain greater economic value within the country, strengthen supply-chain resilience, and reduce vulnerability to external technological and geopolitical pressures.

The Challenge of Global Concentration and Import Dependence

The global shipbuilding industry is highly concentrated, with China, South Korea, and Japan accounting for approximately 95 per cent of global shipbuilding output in 2023. By the beginning of 2025, China alone held 63.7 per cent of the global orderbook by gross tonnage. As the next generation of ships becomes more technologically complex—focusing on alternative fuels, automation, digital systems, energy efficiency, and advanced propulsion—India faces a choice between remaining an assembler of imported technologies or building an integrated domestic maritime technology ecosystem.

Currently, Indian shipyards remain heavily dependent on imports for critical systems, including major engines, generators, navigation systems, electronic equipment, automation systems, communications equipment, and satellite communication systems. The lack of domestic large marine-engine manufacturing is a major vulnerability, as the main engine is one of the most expensive components of a commercial vessel. This foreign dependence exposes domestic shipbuilders to exchange-rate fluctuations, long delivery periods, spare-parts constraints, and geopolitical disruptions.

Addressing the Spare-Parts Trap and Technology Ownership

Navigation and communication systems, such as ECDIS, radar, gyrocompasses, GMDSS equipment, SATCOM terminals, and integrated bridge systems, are largely supplied by foreign manufacturers. While Indian institutions and companies are working on radar, SATCOM, and integrated bridge systems, and NavIC provides a foundation for an indigenous positioning ecosystem, these technologies still require commercial type approval, production scale, and integration into merchant shipping.

Dependence on foreign equipment also creates a "spare-parts trap." A failure in a foreign engine component or electronic system can result in weeks or months of waiting, grounding vessels and increasing operating costs. In times of crisis, this dependence impacts national resilience rather than just commercial efficiency.

To address this, India's policy architecture—which includes the Shipbuilding Financial Assistance Scheme (SBFAS), Maritime Development Fund (MDF), and Shipbuilding Development Scheme (SbDS) constituting a ₹69,725-crore package—must focus on translating financial assistance into domestic technological capability. Experts suggest progressively raising the domestic value addition threshold from the current 30 per cent to 50 per cent, 60 per cent, and eventually higher levels, linking financial assistance to certified Indian suppliers and indigenous intellectual property.

Building a Marine Equipment Manufacturing Cluster

A proposed Marine Equipment Manufacturing Cluster programme could establish dedicated hubs around Kochi/Alappuzha, Visakhapatnam, Surat/Hazira, and Chennai/Ennore. These clusters would bring equipment manufacturers closer to shipyards and provide shared testing, certification, machining, incubation, and supplier-development infrastructure. This is critical because many Indian manufacturers have engineering capabilities but lack the testing infrastructure and classification approvals required for commercial shipbuilding.

Additionally, a dedicated Production-Linked Incentive (PLI) scheme for marine equipment could cover engines, generators, boilers, heat exchangers, power-management systems, navigation equipment, GMDSS, SATCOM, integrated bridge systems, and automation, with higher incentives reserved for technologically intensive systems.

Strategic Frontiers: Engines and Electronics

Developing indigenous marine engines is a key long-term goal. India plans to adopt a staged approach, starting with engines for fishing vessels, inland vessels, and small coastal craft, while pursuing licensed manufacturing and technology transfer for larger engines. The medium-term objective is to develop low-speed two-stroke engines for coastal tankers, bulk carriers, and offshore vessels, eventually progressing to engines for large container ships, Capesize vessels, and VLCCs.

In electronics, India can leverage its existing capabilities in IT, space, and defence. Where security considerations permit, indigenous naval technologies could be transferred to commercial maritime applications after classification and certification. This includes integrating NavIC into domestic marine receivers, launching a national GMDSS indigenisation mission, and establishing an "ECDIS India" programme involving the Indian Maritime University, IITs, IISc, the Directorate General of Shipping, and industry partners.

Phased Roadmap to 2047

India’s technological independence is envisioned in distinct phases:

• 2026–2030: Focus on technology audits, mandatory indigenous-content targets, marine-equipment incentives, common testing infrastructure, and technology-transfer frameworks.
• 2030–2035: Scale domestic propulsion and automation capabilities and demonstrate alternative-fuel vessels using Indian systems.
• Beyond 2035: Enter highly complex vessel categories based on demonstrated productivity, design ownership, and supplier depth.
• By 2047: Achieve more than 70 per cent indigenous content in Indian-built vessels, become a net exporter of marine equipment to Southeast Asia, Africa, and the Middle East, and establish a domestic spare-parts ecosystem to support the national fleet.

By learning from the models of South Korea, China, and Japan, India aims to combine its engineering talent, large domestic market, competitive costs, and strategic location in the Indian Ocean to capture a larger share of the value, technology, and intellectual property embedded in every vessel.
