Utility connections in port – High voltage shore connection (HVSC) systems. General requirements.


IEC/IEEE 80005 is a Triple Logo International Standard jointly developed by the IEC, ISO and IEEE in accordance with conditions determined by agreement between the organizations.
It is written in the form of a performance Standard rather than a detailed prescriptive Standard.

This part of IEC/IEEE 80005 describes high-voltage shore connection (HVSC) systems, onboard the ship and on shore, to supply the ship with electrical power from shore.
It is applicable to the design, installation and testing of HVSC systems and covers
• HV shore distribution systems,
• shore-to-ship connection and interface equipment,
• transformers/reactors,
• semiconductor/rotating frequency convertors,
• ship distribution systems, and
• control, monitoring, interlocking and power management systems.
It does not apply to the electrical power supply during prolonged periods in docks, for example dry docking and other out of service maintenance and repair.
Additional and/or alternative requirements can be imposed by national administrations or the authorities within whose jurisdiction the ship is intended to operate and/or by the owners or authorities responsible for a shore supply or distribution system.
It is expected that HVSC systems will have practicable applications for ships requiring 1 MVA or more or ships with HV main supply.
It is important to note that Low-voltage shore connection systems are not covered by this document.


For a variety of reasons, including environmental considerations, it is becoming an increasingly common requirement for ships to shut down ship generators and to connect to shore power for as long as practicable during stays in port. The scenario of receiving electrical power and other utilities from shore is historically known as “cold ironing”.
The intention of this part of IEC/IEEE 80005 is to define requirements that support, with the application of suitable operating practices, efficiency and safety of connections by compliant ships to compliant high-voltage shore power supplies through a compatible shore-to-ship connection.
Ships that do not apply this document can find it impossible to connect to compliant shore supplies.
Where the requirements and recommendations of this document are complied with, highvoltage shore supplies arrangements are likely to be compatible for visiting ships for connection.

Informative Annex A

Informative Annex A includes cabling recommendations that should be used in HVSC systems. Annex A contains performance-based requirements for shore connection cables and was developed by technical experts from a number of countries. IEC technical committee 18, subcommittee 18A and IEC technical committee 20 were consulted regarding cable requirements. It was determined that existing standards for cable can be used at this time and there is presently no need to develop a separate standard for shore connection cables.
