The shoreside power supply, installed at the port of Lubeck’s Nordland dock, provides ships with an environmentally friendly and economical electrical power supply via the local medium-voltage system while they are berthed in port.
The shoreside power supply has been built for the Swedish-Finnish paper, packaging and forest products company Stora Enso. The first customer of the shoreside power supply is the Swedish shipping line Transatlantic, which includes its paper-carrying ferries Transpaper, Transpulp and Transtimber.
The Transatlantic ships with their 400V/50Hz on-board systems have already been retrofitted for shoreside power supply systems at the port of Kemi in Finland and at the port of Gothenburg, Sweden. The ships have a cable drum with plug-in connector, a control system for the coupling process and a transformer on board.
Ralf Christian, CEO of the power distribution division in the Siemens Energy sector, said: As soon as the ships obtain the power they need via our shore side power supply system, they can switch off their diesel generators while they are berthed in port. These diesel generators not only produce electrical power but also exhaust emissions, soot, particulate matters and noise, so in this way these ships will help to reduce harbor smog which is becoming an increasingly serious environmental problem in many port cities.
