A container-based shore connection for shore-to-ship power supply

A VINCI Energies company in Sweden installs container-based shore connections in shipping ports that are more flexible and can be moved as required.

Suede_HVSC_texte A shore connection, also known as a High Voltage Shore Connection (HVSC) or Cold Ironing, is used to supply electrical power to ships at berth, when their main engines and auxiliaries are not operating, which means they can be connected to the normal power supply. A ship can thus use the power grid to operate its emergency equipment, refrigeration, air-conditioning, heating and lighting installations.

After installing the largest shore connection in the world in the port of Ystad, VINCI Energies has developed a mobile container solution that offers greater freedom in ports. "Most ports have to be flexible, which means that ships have different landing locations over the years. With a mobile shore connection and good planning, it's easier to move the ships around", explains Jonas Klarén, Regional Director for Industry at VINCI Energies in Sweden.

Less pollution, noise and energy

The main advantage of the shore connection system is environmental. Shutting down the main engines and auxiliaries and using power from the national grid means saving a large amount of fuel and reducing greenhouse gas and other pollutant emissions. It also reduces noise both on the ship and in the harbour area.

VINCI Energies provides the buildings, switchgear, frequency converters and transformers as well as the design and commissioning of the plant. It has now installed 8 shore connections, including one in Kristiansand in Norway, the first container-based shore connection. Another shore connection is currently being constructed in the port of Göteborg, in the south of Sweden.
