SHORE POWER
The marine shore power system refers to the overall equipment that supplies shore power to docked ships.
Stopping the ship's generator and using shore power during the ship's berthing period
can improve overall efficiency and reduce CO2 emissions to a certain extent.
Why ships should use shore power?
Traditional ships rely on auxiliary engines to generate electricity 24h/day when docked,
causing three critical issues:
High fuel consumption
Auxiliary engines burn costly diesel continuously.
Severe pollution
Exhaust (CO₂, sulfides) and particulate matter degrade air quality.
Noise pollution
>90dB noise disrupts crew and port operations.
Shore Power (Cold Ironing) replaces onboard generators with land-based electricity, achieving zero fuel consumption, zero emissions, and silent operation during berthing.
Core Components of
Ship Shore Power Systems
A complete shore power system operates through three integrated modules
| Module | Function | Key Equipment |
| Shore-based Power Supply | Converts port grid power to ship-compatible electricity | Port substation, shore power box-type substation (transformer/frequency converter) |
| Ship Receiving System (AMPS) | Receives and regulates shore power input | Ship switchboard, voltage stabilizer |
| Ship-Shore Connection Equipment | Enables rapid cable connection between dock and vessel | HV cable reel, smart connection cabinet |
