Shore to Ship Power Supply System

Features

Shore to Ship Power Supply System for Safe, Reliable, and Environmentally Conscious Ports

Features of Our System

1.

Power can be supplied at any voltage and frequency.
2.

We offer a broad lineup of capacities, allowing you to select the optimal option for the application
3.

The system enables automatic synchronization and desynchronization with the ship’s onboard generator.
4.

Even in the event of equipment failure or inspection, the number of units can be reduced by disconnecting parts of the equipment (enabling continued operation).

Benefits of Implementation

Reducing Exhaust Gas and CO2 Emissions

For ships at berth, the required electric power is transmitted from the shore, and the onboard generator is shut down. The system reduces emissions of NOx, SOx, and other air pollutants, as well as CO2.

Compact Package

The power supply equipment is packaged and delivered in a 40-foot container. This improves the ease of installation, contributing to reduced construction time and faster deployment.
