Ports using OPS

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 HzV
Kemi	Finland	6.6 kV		50 HzV
Oulu	Finland	6.6 kV		50 HzV
Kotka	Finland	6.6 kV		50 HzV
Lübeck	Germany	6.6 kV		50 HzV
Zeebrugge	Belgium	6.6kV		50 HzV
Los Angeles	U.S.A	6.6 kV/11 kV		60 Hz
Long Beach	U.S.A	6.6 kV	480 V
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
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)
