Chidambaranar Port Authority—to cease procuring conventional diesel-mechanical towing vessels immediately. The statutory directive establishes a binding transition framework under which at least 65% of all harbor towage assets must run on zero-emission propulsion architectures by 2030, scaling to a 100% zero-emission harbor craft fleet across all state-administered ports by 2035.</p><h6 data-path-to-node="4"><b>Capital Subsidy Structure and Domestic Fabrication Mandates</b></h6><p data-path-to-node="5">To bridge the initial capital expenditure premium between conventional diesel harbor tugs and next-generation clean propulsion craft, the Cabinet has earmarked an upfront budgetary subsidy allocation of ₹14,200 crore to underwrite vessel acquisition and yard outfitting. Under the finalized financial disbursement framework, domestic port authorities and licensed concessionaire terminal operators will receive direct capital subsidies of up to 40% on standard 60-to-85-tonne Bollard Pull (BP) green tug acquisitions, provided the vessels are engineered and fabricated at accredited Indian shipyards.</p><p data-path-to-node="6">To maximize domestic manufacturing multipliers under the <i data-path-to-node="6" data-index-in-node="57">Make in India</i> and <i data-path-to-node="6" data-index-in-node="75">Atmanirbhar Bharat</i> charters, the guidelines impose strict localization 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">Domestic Content Thresholds:</b> Shipyards securing vessel orders must achieve an initial domestic content requirement (DCR) of 65% for structural steel fabrication, high-voltage battery enclosures, power conversion systems, and propulsion shafts, rising to 80% for hull orders placed after April 2028.</p></li><li><p data-path-to-node="7,1,0"><b data-path-to-node="7,1,0" data-index-in-node="0">Lead Shipyard Integration:</b> Public and private commercial yards—including Cochin Shipyard Limited (CSL), Garden Reach Shipbuilders &amp; Engineers (GRSE), Goa Shipyard Limited (GSL), and Larsen &amp; Toubro Shipbuilding—will manufacture standardized tug types developed in partnership with the Indian Register of Shipping (IRS) and the Directorate General of Shipping (DGS).</p></li><li><p data-path-to-node="7,2,0"><b data-path-to-node="7,2,0" data-index-in-node="0">Ban on Conventional Charters:</b> Major Port Authorities and private multi-user container and bulk terminals are formally prohibited from entering into long-term charter agreements exceeding six months for foreign-built, fossil-fuel-burning harbor vessels.</p></li></ul><h6 data-path-to-node="8"><b>Standardized Vessel Classes and Clean Fuel Pathways</b></h6><p data-path-to-node="9">To compress construction schedules and prevent non-standard hull variants, the NGTTP circular specifies four standardized vessel categories optimized for harbor operations:</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">Category 1 (Battery-Electric Harbor Craft):</b> Outfitted with 3.5 to 5.2 MWh modular lithium-iron-phosphate (LFP) marine battery packs, designed specifically for enclosed harbor maneuvers, vessel docking, and inner-channel escort duties.</p></li><li><p data-path-to-node="10,1,0"><b data-path-to-node="10,1,0" data-index-in-node="0">Category 2 (Hydrogen Fuel-Cell Hybrids):</b> Integrating proton-exchange membrane (PEM) fuel-cell systems with auxiliary battery buffers, tailored for long-endurance harbor patrolling, emergency response, and deep-draft channel towage.</p></li><li><p data-path-to-node="10,2,0"><b data-path-to-node="10,2,0" data-index-in-node="0">Category 3 (Green Methanol Dual-Fuel):</b> Heavy-duty 85+ tonne BP escort tugs built for maneuvering Ultra-Large Container Vessels (ULCVs) and Capesize dry bulk carriers in exposed offshore conditions.</p></li><li><p data-path-to-node="10,3,0"><b data-path-to-node="10,3,0" data-index-in-node="0">Category 4 (Bio-LNG / Dual-Fuel Transition Craft):</b> Transitional alternatives approved for high-tonnage energy terminals handling LNG and crude imports.</p></li></ul><h6 data-path-to-node="11">Landside Megawatt Charging and Bunkering Grids</h6><p data-path-to-node="12">A core pillar of the approved capital package is the deployment of quayside utility networks across all 12 major gateways.
