OPS (Onshore Power Supply)
Own Design & Manufacturing — 140+ Shore Power Installations Across Major Ports & Terminals
With over 140 shore power installations delivered — including all major California ports — Integri Marine is one of the most experienced turnkey AMP (Alternate Marine Power) solution providers for ships and port terminals worldwide. Our systems are designed and manufactured in-house, giving us full control over quality, lead times, and customisation to meet the exact operational profile of every berth and vessel type.
Shore power (also known as Cold Ironing or Onshore Power Supply / OPS) allows vessels to connect to the shoreside electrical grid at berth and shut down their auxiliary engines — eliminating stack emissions, reducing noise, cutting fuel costs, and ensuring compliance with CARB, EU ETS, FuelEU Maritime, and IMO MARPOL Annex VI regulations.
We supply both mobile and fixed cable management systems purpose-built for terminals, covering HVSC (High Voltage Shore Connection) and LVSC (Low Voltage Shore Connection) configurations across container, cruise, RoRo, tanker, and bulk carrier berths. Every project is delivered as a complete turnkey package — from feasibility study and class-approved detailed engineering through to installation, commissioning, and crew training.

iAMP-CRD is Integri Marine's complete turnkey Onshore Power Supply (OPS) / Alternative Marine Power (AMP) solution for vessels at berth. It enables ships to connect to shore-based electrical power, shutting down their auxiliary diesel generators and eliminating all port-stay emissions. The solution is delivered as a full package covering consultation, feasibility, detailed engineering, class coordination, procurement, installation, commissioning, and sea trials.
An OPS system includes a shore-based power connection panel, high-voltage or low-voltage switchgear, a power transformer (for voltage and/or frequency conversion), a Cable Management System (CMS) for deploying the heavy shore cable, and a Shore Connection Control Panel (SCCP) aboard the vessel. The vessel's main switchboard is modified with a changeover panel to accept shore power in place of generator output. Integri Marine supplies and installs all components as a turnkey package.
Yes. A key advantage of Integri Marine's iAMP-CRD solution is its afloat installation capability. The vessel-side retrofit can be carried out while the ship remains operational and afloat, without the need for dry docking. This minimises out-of-service time and reduces overall project costs significantly.
By replacing auxiliary diesel generator operation with shore power, OPS eliminates essentially all exhaust emissions from the vessel during its port stay — including nitrogen oxides (NOx), sulphur oxides (SOx), carbon dioxide (CO2), carbon monoxide (CO), and particulate matter (PM). This improves air quality in port cities and helps vessel operators comply with IMO, EU ETS, FuelEU Maritime, and port authority emission requirements.
Yes. Integri Marine coordinates all class approvals for iAMP-CRD installations with major classification societies . All engineering documentation, material certifications, and installation procedures are prepared and submitted in accordance with the applicable class rules for HVSC (IEC/ISO/IEEE 80005-1) and LVSC (IEC/ISO/IEEE 80005-3) systems.
FuelEU Maritime is a European Union regulation (Regulation (EU) 2023/1805) that mandates a progressive reduction of greenhouse gas intensity in maritime fuels from 2025 onward. Crucially, from 2030, FuelEU Maritime requires containerships and passenger vessels calling at EU ports to connect to Onshore Power Supply (OPS / shore power) while at berth — where port infrastructure is available. Non-compliance incurs per-voyage penalties. Integri Marine's iAMP-CRD solution provides a certified, turnkey OPS retrofit that ensures full FuelEU Maritime compliance, covering vessel-side engineering, class approval, and commissioning.
The EU Emissions Trading System (EU ETS) was extended to the maritime sector from 2024, requiring shipowners to surrender carbon allowances (EUAs) for CO2 emitted during voyages to, from, and between EU ports — including port stays. By connecting to Onshore Power Supply (OPS / cold ironing) at EU ports, ships shut down their auxiliary diesel generators and eliminate port-stay CO2 emissions, directly reducing the number of EUAs required and lowering the vessel's carbon tax liability. Integri Marine's iAMP-CRD system is designed specifically to meet the IEC/ISO/IEEE 80005 standards required for EU ETS compliance documentation.
The California Air Resources Board (CARB) At-Berth Ocean-Going Vessels Regulation requires visiting container ships, passenger vessels, and refrigerated cargo ships to reduce auxiliary diesel engine use by 50% at regulated California ports, rising to 80% by 2020 and 100% for new vessels. The regulation mandates connection to shore power (cold ironing / Onshore Power Supply) as the primary compliance method. Integri Marine's iAMP-CRD system is engineered to meet all CARB OPS technical requirements, including high-voltage shore connection standards and cable management system specifications, supporting vessel operators calling at Los Angeles, Long Beach, Oakland, and other CARB-regulated California ports.
