Backed by a grant of €1.5M from the state of Lower Saxony (Niedersachsen), the state’s ports authority Niedersachsen Ports (NPorts) has installed Siemens’ Siharbor shore power supply system at the offshore ro-ro vessel berth, so vessels can “cold iron” instead of adding to pollution with emissions from auxiliary engines

EWE Netz was the main contractor to connect the ro-ro berths to the 20 kV public grid and Siemens AG was the main subcontractor for the new infrastructure at the berth. The Siemens installation includes the complete transformer station, a Stemmann-Technik ShoreConnect cable feed system, the supply of two transformers, as well as installation of an 8DJH MV switchgear and the Sivacon S8 LV main distribution system.

An 8m tall high cable entry was erected to move the cable via a rolling system onto the vessel. This is the first time that Siemens has installed a low voltage convertor with 630kW power output into its Silharbor shore power supply system.

Siemens will be the main user of the berth as it is adjacent to the new factory for wind turbines operated by Siemens Gamesa, which will ship wind turbine components to its sister factory in Hull, UK.
