Cold Ironing & Onshore Power Supply (OPS)Alternative Marine Power · Shore Connection · Zero Emissions at Berth
Cold ironing — also known as Onshore Power Supply (OPS), Alternative Marine Power (AMP), or Shore Power — is the most effective way to achieve zero emissions at berth. Integri Marine & Offshore Services delivers comprehensive, turnkey Cold Ironing and Onshore Power Supply solutions for shipowners, port operators, and offshore terminals across India, Europe, Dubai, and beyond. Our services span the complete project lifecycle: feasibility and CAPEX analysis, High Voltage Shore Connection (HVSC, IEC/ISO/IEEE 80005-1) and Low Voltage Shore Connection (LVSC, IEC/ISO/IEEE 80005-3) system design, vessel retrofit engineering, cable management system supply, power transformer and frequency converter integration, class coordination with DNV, ABS, Lloyd's Register, Bureau Veritas, and IRS, and commissioning and sea trials. Shore power connections eliminate up to 100% of NOx, SOx, CO2, and particulate matter (PM) from auxiliary diesel generators during port stays, helping shipowners comply with FuelEU Maritime, the EU Alternative Fuels Infrastructure Regulation (AFIR), EU ETS carbon pricing, and California CARB At-Berth regulations. Whether you need a port-side infrastructure build, a vessel-side cold ironing retrofit, or a complete end-to-end shore connection system, Integri Marine provides certified, cost-effective Onshore Power Supply solutions.

Cold ironing, also known as Shore Power, Alternative Marine Power (AMP), or Onshore Power Supply (OPS), is the process of providing shore-side electrical power to a ship at berth while its main and auxiliary engines are shut down. This technology eliminates local air emissions (NOx, SOx, PM) and greenhouse gases (CO2) from auxiliary engines, ensuring compliance with global environmental regulations (such as FuelEU Maritime, EU ETS, and CARB). Integri Marine designs and installs complete turnkey solutions complying with IEC/ISO/IEEE 80005 standards.
Integri Marine supplies complete turnkey shore power systems for both vessel retrofits and port infrastructure. Our engineering services cover High Voltage Shore Connections (HVSC >1 kV per IEC/ISO/IEEE 80005-1) and Low Voltage Shore Connections (LVSC ≤1 kV per IEC/ISO/IEEE 80005-3). These systems feature advanced cable management systems, frequency converters (50/60 Hz), isolation transformers, safety interlocking, and shore connection control panels. Our globally located offices in Rotterdam, Hamburg, Copenhagen, Dubai, Mumbai, and Chennai provide end-to-end local project support.
Yes, Integri Marine specializes in afloat installation of shore power systems, allowing vessels to be retrofitted without dry docking. This process minimizes vessel downtime and operational disruption. Our engineering team designs custom structural and electrical integration solutions tailored to the vessel's layout, managing class approval and commissioning while the vessel remains afloat in key regions, including European, Indian, and Middle Eastern waters.
Shore power and cold ironing compliance are governed by international standards IEC/ISO/IEEE 80005 (Part 1 for HVSC, Part 3 for LVSC) and IMO MEPC.1/Circ.869. Key regional regulations mandating shore connection include the European Union's FuelEU Maritime regulation and Alternative Fuels Infrastructure Regulation (AFIR) — which mandate shore power for containerships and passenger vessels by 2030 — the EU ETS carbon pricing, and the California Air Resources Board (CARB) At-Berth Ocean-Going Vessels Regulation. Integri Marine guarantees full compliance with these regulatory standards.
Connecting to Onshore Power Supply (OPS) instead of running auxiliary diesel generators offers substantial economic benefits: 60% to 80% reduction in auxiliary power energy costs depending on local port electricity tariffs versus marine fuel prices; significant reduction in auxiliary engine wear and maintenance intervals, saving on spare parts and overhaul costs; avoidance of carbon tax penalties under regulations like EU ETS and FuelEU Maritime; and lower port dues through green port incentive schemes. Integri Marine's global engineering offices carry out custom feasibility studies and return-on-investment (ROI) calculations for vessel operators.
Yes, Integri Marine provides comprehensive classification society approval and certification support for all cold ironing retrofits. We manage class design review, safety analysis, plan approval, and on-board survey coordination with major IACS societies including DNV, ABS, Lloyd's Register (LR), Bureau Veritas (BV), and Indian Register of Shipping (IRS). Our team ensures the vessel is successfully certified with the appropriate class notations (e.g., Shore Power, OPS, or AMP).
