Ports using OPS

Bookmark and Share

Ports using OPS systems have been developed in North America as well as Europe for seagoing ships. As the following table illustrates, the absence of pertinent standards and differences in electrical layouts of grids and ships have resulted in differences in several aspects.

Port Country High Voltage Low voltage Frequency
Antwerp Belgium 6.6 kV   50 Hz/60 Hz
Goteborg Sweden 6.6 kV/10 kV 400 V 50 Hz
Helsingborg Sweden   400 V/440 V 50 Hz
Stockholm Sweden   400 V/690 V 50 HzV
Piteå Sweden 6 kV   50 Hz
Kemi Finland 6.6 kV   50 Hz
Oulu Finland 6.6 kV   50 Hz
Kotka Finland 6.6 kV   50 Hz
Lübeck Germany 6.6 kV   50 Hz
Zeebrugge Belgium 6.6kV   50 Hz
Los Angeles U.S.A 6.6 kV/11 kV   60 Hz
Long Beach U.S.A 6.6 kV 480 V 60 Hz
San Francisco U.S.A 6.6 kV/11 kV   60 Hz
San Diego U.S.A 6.6 kV/11 kV   60 Hz
Seatlle U.S.A 6.6 kV/11 kV   60 Hz
Juneau U.S.A 6.6 kV/11 kV   60 Hz
Pittsburg U.S.A   440 V 60 Hz
Vancouver Canada      
Oslo Norway 6.6kv   50Hz
Rotterdam Netherlands 6.6kv   50Hz

The power of the installations in the various ports depends on the power requirements of the ships calling. For an overview of average power requirements, click here.

Recent developments

Several ports are currently implementing OPS, thus extending the scope of its application. These include:
-the Port of Le Havre (France)
-the Port of Marseille (France)
-the Port of Civitavecchia (Italy)
