Cold ironing, also known as shore power or Onshore Power Supply (OPS), is a technology that allows ships to switch off their auxiliary diesel engines while berthed and connect to the port's electrical grid. This eliminates all engine exhaust emissions — including NOx, SOx, CO2, and particulate matter — during port stays, significantly improving air quality in port cities and helping vessel operators meet IMO and EU emissions regulations.
Integri Marine provides complete turnkey shore power systems for both port infrastructure and vessel retrofits. Our solutions include HVSC (High Voltage Shore Connection, >1 kV) and LVSC (Low Voltage Shore Connection, ≤1 kV) systems, cable management systems, frequency converters (50/60 Hz), power transformers, shore connection control panels, safety interlocking, and remote monitoring. We manage the full project from feasibility through commissioning.
Yes. Integri Marine has the capability to install shore power systems aboard vessels while they remain afloat, without requiring dry docking. This significantly reduces vessel downtime and operational costs. Our team designs customised retrofit solutions that accommodate the vessel's existing electrical architecture, and we coordinate all class approvals for afloat installation.
Shore power is governed by IMO MEPC.1/Circ.869, IEC/ISO/IEEE 80005-1 (HVSC) and IEC/ISO/IEEE 80005-3 (LVSC), the EU Directive on the deployment of alternative fuels infrastructure (AFID), and various national port authority regulations. The EU's FuelEU Maritime regulation and the revised EU ETS (Emissions Trading System) are also driving accelerated adoption. Integri Marine's shore power solutions are designed to meet all applicable international and port-specific standards.
Shore power typically reduces fuel costs for auxiliary power generation by 60–80% depending on local electricity tariffs versus bunker fuel prices. Additional savings come from reduced engine wear and maintenance, lower air quality compliance penalties, and potential eligibility for port dues discounts offered by green port programs. Integri Marine provides feasibility studies that quantify the specific ROI for each vessel and port scenario.
Yes. Integri Marine handles all regulatory certification for cold ironing projects, including IMO compliance documentation, classification society approval (DNV, ABS, Bureau Veritas, Lloyd's Register, etc.), port authority approvals, and flag state endorsements. Our engineers ensure that both the shore-side infrastructure and the vessel-side retrofit meet all applicable safety and emissions standards.
