SUPPLYING HIGH VOLTAGE SHORE CONNECTION (HVSC) SYSTEM USING ENERGY EFFICIENT EQUIPMENT IN THE GREAT PORT OF VALLETTA
MALTA
The project allows cruise ships and cargo ships to shut down their kerosene or heavy fuel oil engines while docked and plug in shore electricity to power their onboard systems.
