It features a frequency converter and a software for central controlling of the two berths. With the system, two medium-voltage networks with different frequencies can be connected. In this case the local distribution grid with 50 Hz and the ship’s onboard electrical system with 60 Hz. Siplink synchronizes both networks and takes over the power supply automatically within a few minutes. In addition, it coordinates the energy supply of the ships’ two networks so that power can be supplied to both simultaneously.
“With this set up, we are able for the first time to supply two ships simultaneously with the necessary 60-Hz onboard frequency by means of one shore power system,” said Axel Mohr, head of sales for Distribution Systems, Region North, at Siemens Smart Infrastructure. “We’re excited to support the Port of Kiel with this sustainable solution, thereby taking on a leading role in Europe together. Such systems will become increasingly important in the future, also outside of Germany, as climate protection goals are implemented.
With its “Master Plan for 100% Climate Protection”, the City of Kiel has an ambitious roadmap to be CO2-neutral by 2050. The new shore power system at the Port of Kiel aims to support this goal with the reduction in CO2 emissions it will bring. The shoreside power supply installed by Siemens in the spring of 2019 at the Norwegenkai has already started operations. To date, it has helped slash CO2 emissions by about 1,000 tons.
