First European Onshore Power Supply for Cruise Ships
One of the main causes of local air pollution in ports is the combustion of ship fuels for generating electricity during lay days. Reducing harmful emissions due to shipping is a concern in port cities around the world.
The Hamburg Port Authority (HPA) has commissioned Siemens to build a turnkey onshore power supply at the Hamburg Altona cruise terminal. The system will supply electricity to cruise ships of all common sizes and electrical system designs, allowing them to turn off their own diesel generators and reduce harmful emissions during their lay days.
The first European onshore power supply system of this type has a capacity of 12 megavolt amperes (MVA) and works with a patented, mobile robot arm designed specifically for the tidal range. The heart of the system is a frequency converter with control software that adjusts the frequency of the local distribution grid to the ship’s electrical system. Commissioning is scheduled for the spring of 2015.
The system has a specially developed cable management system for cruise ships that provides a fast, easy and flexible connection between the shore and the ship. The system is self-propelled and can be automatically operated from the ship as needed, so that no additional specialists are needed on shore. A concrete channel along the quay wall guides a high tide-resistant cable chain for system mobility and is designed with a length of 300 meters for this project. A robot arm is used to transport the power cable connectors and the communication link into the ship through the outer hatch, like on a tray. Developed jointly between Siemens and Stemmann Technik in Schüttorf, this technology also compensates for the tidal range during power supply.
