Seehafen Kiel GmbH, the port of Kiel, Germany, has commissioned Siemens AG to construct two additional ‘Siharbor’ shore side power plants at Kiel’s Ostuferhafen. The construction project, with a total investment value of approximately €17 million, comprises a 50/60 Hz shore power plant for cruise ships and ferries and a 50 Hz plant for ferries. It means that the power supply ships need while they are in port can be sourced from renewable energy on shore instead of diesel generators on board.
The new shore power connection will be one of the largest installations of its kind in Europe. After completion of the project at the end of 2023, the port of Kiel will be able to supply green power to six ships simultaneously at all of its major passenger, cargo and ferry terminals. “Connecting ships to shore power has enormous economic and environmental impact. Ships save expensive fuel, new business models open up for port operators, and port staff and residents benefit from a significant reduction in noise and pollution,” said Markus Mildner, CEO of Siemens eMobility.
For Siemens, the contract includes execution planning, delivery, assembly, cabling and commissioning of all plant and structural components required for the operation of the shore power plants, the necessary structural, civil and hydraulic engineering work, and overall commissioning of the system.?
Siemens won the contract following an EU-wide invitation to tender and a negotiation procedure with a preliminary qualification competition.
The existing shore power plants at Ostseekai and Schwedenkai as well as at Norwegenkai were also built by Siemens. ? ?
The construction project at Ostuferhafen includes two shore power plants able to supply up to three seagoing vessels simultaneously. The first of the two shore power plants is designed to supply up to two ferry or cruise ships and connects four berths at Ostuferhafen to shore power. It has a capacity of 16 MVA and can supply cruise ships and ferries with a frequency of 50 or 60 Hz and a voltage of 6.6 kV or 11 kV. The second plant, at a grid frequency of 50 Hz, is designed exclusively for cargo and RoRo vessels and supplies two berths with a voltage of 6.6 kV or 11 kV, up to a maximum capacity of 5 MVA. ?
