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.

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)
