<p data-path-to-node="2"><b data-path-to-node="2" data-index-in-node="0">NEW DELHI</b> — In a major regulatory and capital allocation drive aimed at eliminating fossil fuel emissions across Indian coastal harbors and establishing sovereign shipbuilding capabilities in clean propulsion, the Ministry of Ports, Shipping and Waterways (MoPSW) has officially notified the Phase-2 operational directives and capital outlay for the ₹15,000-crore National Green Tug Transition Programme (NGTTP).</p><p data-path-to-node="3">The statutory directive, formulated in consultation with the Directorate General of Shipping (DGS) and the Indian Register of Shipping (IRS), mandates that all 12 Major Port Authorities—including Jawaharlal Nehru Port Authority (JNPA), Deendayal Port Authority (Kandla), Paradip Port, and V.O. Chidambaranar Port Authority—must execute firm phaseout roadmaps for legacy diesel harbor tugs. Under the Phase-2 mandate, at least 50% of each major port's active harbor-assist fleet must be replaced with battery-electric, green methanol-capable, or hydrogen hybrid propulsion vessels by 2030, scaling to a 100% zero-emission harbor fleet mandate nationwide by 2035.</p><h6 data-path-to-node="4"><b>Capital Subsidy Structure and Indigenous Yard Incentives</b></h6><p data-path-to-node="5">To address the higher upfront capital cost of electric powertrains and cryogenic alternative fuel systems compared to conventional diesel configurations, the Phase-2 notification earmarks ₹7,200 crore as direct capital subsidies under the expanded Shipbuilding Financial Assistance Scheme (SBFAS). Domestic public and private shipyards building under standardized Bureau of Indian Standards (BIS) and IRS design frameworks will qualify for upfront grants covering up to 35% of the total vessel construction and outfitting costs for standard 60-to-85-tonne Bollard Pull (BP) green tugs.</p><p data-path-to-node="6">To protect the domestic industrial base under the <i data-path-to-node="6" data-index-in-node="50">Make in India</i> and <i data-path-to-node="6" data-index-in-node="68">Atmanirbhar Bharat</i> charters, the notification codifies strict procurement rules:</p><ul data-path-to-node="7"><li><p data-path-to-node="7,0,0"><b data-path-to-node="7,0,0" data-index-in-node="0">Progressive Domestic Sourcing:</b> Vessels awarded under NGTTP Phase-2 tenders must achieve an initial domestic content requirement (DCR) of 60% for structural steel, power management systems, and electric drivetrains, escalating to 75% for orders placed after December 2027.</p></li><li><p data-path-to-node="7,1,0"><b data-path-to-node="7,1,0" data-index-in-node="0">Yard Allocations:</b> Commercial yards—including Cochin Shipyard Limited (CSL), Garden Reach Shipbuilders &amp; Engineers (GRSE), Goa Shipyard Limited (GSL), and accredited private shipbuilding facilities—have been designated as lead manufacturing partners to fabricate modular hulls using standardized IRS naval blueprints.</p></li><li><p data-path-to-node="7,2,0"><b data-path-to-node="7,2,0" data-index-in-node="0">Foreign Charter Ban:</b> Major Port Authorities and licensed multi-user terminal concessionaires are formally barred from issuing new long-term operational charters exceeding six months for foreign-flagged, conventional fossil-fueled harbor tugs.</p></li></ul><h6 data-path-to-node="8"><b>Standardized Modular Propulsion Types</b></h6><p data-path-to-node="9">The Ministry’s technical circular outlines three standardized vessel classifications to streamline shipyard workflows and reduce component costs:</p><ul data-path-to-node="10"><li><p data-path-to-node="10,0,0"><b data-path-to-node="10,0,0" data-index-in-node="0">Class-A (Battery-Electric Harbor Craft):</b> Outfitted with 3.5 to 5.0 MWh modular lithium iron phosphate (LFP) marine battery banks, specifically designed for inner-harbor vessel assists, docking maneuvers, and calm channel towage.</p></li><li><p data-path-to-node="10,1,0"><b data-path-to-node="10,1,0" data-index-in-node="0">Class-B (Hydrogen Hybrid Craft):</b> Integrating proton-exchange membrane (PEM) fuel cells with auxiliary battery storage, tailored for extended coastal towing, emergency response, and long-endurance pilot escort duties.</p></li><li><p data-path-to-node="10,2,0"><b data-path-to-node="10,2,0" data-index-in-node="0">Class-C (Green Methanol Dual-Fuel Tugs):</b> Heavy-duty 85+ tonne Bollard Pull escort tugs engineered to maneuver Ultra-Large Container Vessels (ULCVs) and fully laden Capesize bulk carriers at exposed offshore berths and deepwater moorings.</p></li></ul><h6 data-path-to-node="11"><b>Landside Shore-Charging and Green Bunkering Infrastructure</b></h6><p data-path-to-node="12">Under the Phase-2 framework, major port trusts must allocate dedicated utility berths retrofitted with automated, high-voltage shore connection (HVSC) DC charging arms capable of delivering 2 to 3.5 megawatts of rapid turnaround electricity.
