4 General information on Onshore power supply Old expression from the shipping industry, that first came into use when all ships had coal fired iron clad engines When a ship tied up at the harbour there was no need to continue to feed the fire and the iron engines would literally cool down eventually going completely cold, hence the term cold ironing Has been used by the military at naval bases for many years when ships are docked for long periods. Today shipping industry is an important link in the international system of goods movement and is increasing rapidly in size and power. Marine transport of goods is responsible for roughly 90 % of the world trade While in port, ships use their diesel auxiliary engines to produce electricity for hotelling, unloading and loading activities. Main engines are usually switched off soon after berthing. together with aviation, shipping is the biggest emitter of pollution in the European Union One of the key forces behind shore-to-ship electrification is the EU directive 2005/33/EC that will come into force the 1 st of January 2010, and affects every single ship while at berth in a European port more than two hours. One measure to reduce emissions while at berth, is to provide electricity to the ships from the national grid instead of producing electricity by the ships own auxiliary diesel generators.

9 Standards are needed Due to the amount of diffrent type of vessels size and power in international water, a common standard is required in order to reduce the compatibility issues. Standard for shore connection is ongoing, and expected to be released as IS during Q Name of standard: IEC/ISO/IEEE The standard is to be valid in IEC/ISO/IEEE groups, and will be a worldwide standard. Its purpose is to define: The electrical parameters which are necessary to enable connection in-between port and harbor Intended for vessels in the power range of 1-20MVA 6.6kV or 11kV, 50Hz or 60Hz Power quality requirements Galvanic separation Engineering 1.
