Marine Power Solutions (Shore Power)
Shore-to-ship frequency converter and distribution systems enabling vessels to run on onshore electricity at berth, eliminating auxiliary engine emissions in port.
Shore power (also called cold ironing or Alternative Maritime Power) is the system by which a vessel at berth shuts down its diesel auxiliary engines and instead draws electrical power from the port's onshore grid — eliminating the exhaust emissions, noise, and fuel costs associated with prolonged harbour idle. ElectroAir's marine power solutions bring the company's frequency converter expertise to this adjacent application: port operators and naval bases present exactly the same technical challenge as airports (a frequency conversion requirement — typically from the local grid standard to the ship's operating frequency), but at significantly higher power levels and with different environmental and regulatory standards. The onshore product line includes shore-side frequency converters, electrical shore connection (ESC) cabinets, and modular or containerised configurations suited to retrofit on existing berths or integration into new port infrastructure. The offshore line covers integrated shipboard converters and hybrid marine power interfaces. Key certifications include IMO compliance and ISO/IEC component standards. Models include the EAC-250M mobile shore power converter and the EAC-400M 400 Hz marine converter. For procurement officers at port authorities, naval bases, or ferry operators exploring shore power mandates (increasingly required under IMO and EU regulations), ElectroAir's marine range is the cross-sell from an established relationship on the aviation side.
