Overview

IEC/ISO/IEEE 80005-1:2012 - Utility connections in port, Part 1: High Voltage Shore Connection (HVSC) Systems – General requirements - defines the general design, installation, testing and operational requirements for supplying ships with electrical power from shore (shore power / shore supply). The standard covers both shore-side and shipboard HVSC equipment and systems, and excludes electrical supply during dry docking or out-of-service maintenance.

Key topics and technical requirements

The standard provides a comprehensive framework for high-voltage ship-to-shore power connections, including:

• System scope and description: definitions of HV shore distribution and ship distribution interfaces and a typical HVSC system architecture.
• Shore-to-ship interface equipment: requirements for plugs, socket-outlets, cable management systems, pilot and earth contacts, and slip-ring units.
• Transformers, reactors and converters: provisions for on-shore and on-board transformers, neutral earthing resistors, semiconductor and rotating converters.
• Protection, control and monitoring: shore-to-ship protection systems, interlocking, instrumentation, power management and fault detection (earth-fault and current unbalance monitoring).
• Safety and personnel protection: equipotential bonding, emergency shutdown and interlocks, safe handling procedures for HV plugs and earthing switches.
• Design, installation and environmental requirements: moisture/condensation protection, degree of protection (IP), location and construction considerations, and suitability in areas with flammable atmospheres.
• Verification, initial and periodic testing: commissioning tests, first-call checks at shore supply points, and recurring maintenance and verification procedures.
• Documentation: required system descriptions, test records and maintenance procedures.

The standard also includes normative annexes with additional requirements for specific ship types (Ro‑Ro, cruise ships, container ships, LNG carriers, tankers).

Practical applications and who uses this standard

IEC/ISO/IEEE 80005-1 is intended for stakeholders involved in delivering and operating shore power systems:

• Port authorities and marine terminal operators specifying shore-side HV infrastructure
• Ship designers, naval architects and shipyards integrating shore connection systems
• Marine electrical engineers and OEMs supplying transformers, converters, plugs and cable management systems
• Ship operators and cruise lines implementing shore power procedures to reduce onboard emissions
• Classification societies, inspectors and regulators assessing compliance and safety
• Maintenance teams conducting commissioning and periodic testing

Adoption of HVSC systems enables ships to shut down onboard generators while berthed, reducing fuel consumption and local emissions when connected to shore power.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation.
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily
members of IEEE and serve without compensation. While IEEE administers the process and establishes rules
to promote fairness in the consensus development process, IEEE does not independently evaluate, test, or
verify the accuracy of any of the information contained in its standards. Use of IEEE Standards documents is
wholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers
(see http://standards.ieee.org/IPR/disclaimers.html for more information).
IEC collaborates closely with ISO and IEEE in accordance with conditions determined by agreement between
the organizations. This Triple Logo International Standard was jointly developed by the IEC, ISO and IEEE
under the terms of that agreement.
2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus of
opinion on the relevant subjects since each technical committee has representation from all interested IEC
National Committees. In the ISO, Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International Standard requires approval by at
least 75 % of the member bodies casting a vote. The formal decisions of IEEE on technical matters, once
consensus within IEEE Societies and Standards Coordinating Committees has been reached, is determined by
a balanced ballot of materially interested parties who indicate interest in reviewing the proposed standard. Final
approval of the IEEE Standard document is given by the IEEE Standards Association (IEEE-SA) Standards
Board.
3) IEC/ISO/IEEE Publications have the form of recommendations for international use and are accepted by IEC
National Committees/ISO member bodies /IEEE Societies in that sense. While all reasonable efforts are made
to ensure that the technical content of IEC/ISO/IEEE Publications is accurate, IEC, ISO or IEEE cannot be held
responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
(including IEC/ISO/IEEE Publications) transparently to the maximum extent possible in their national and
regional publications. Any divergence between any IEC/ISO/IEEE Publication and the corresponding national or
regional publication shall be clearly indicated in the latter.
5) IEC, ISO and IEEE do not provide any attestation of conformity. Independent certification bodies provide
conformity assessment services and, in some areas, access to IEC marks of conformity. IEC, ISO and IEEE are
not responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC, ISO or IEEE or their directors, employees, servants or agents including
individual experts and members of technical committees and IEC National Committees and ISO member
bodies, or volunteers of IEEE Societies and the Standards Coordinating Committees of the IEEE Standards
Association (IEEE-SA) Standards Board, for any personal injury, property damage or other damage of any
nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the
publication, use of, or reliance upon, this IEC/ISO/IEEE Publication or any other IEC, ISO or IEEE Publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that implementation of this IEC/ISO/IEEE Publication may require use of
material covered by patent rights. By publication of this standard, no position is taken with respect to the
existence or validity of any patent rights in connection therewith. IEC, ISO or IEEE shall not be held responsible
for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the

legal validity or scope of Patent Claims or determining whether any licensing terms or conditions provided in

connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or
non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent

rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be

obtained from ISO or the IEEE Standards Association.

INTRODUCTION
The following standard was developed jointly between IEC technical committee 18: Electrical

installations of ships and of mobile and fixed offshore units, ISO technical committee 8: Ships

and marine technology, subcommittee 3: Piping and machinery, and IEEE IAS PCIC Marine

industry subcommittee.
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 standard 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.
With the support of sufficient planning, cooperation between ship and terminal facilities, and
appropriate operating procedures and assessment, compliance with the requirements of this
standard is intended to allow different ships to connect to high-voltage shore connections
(HVSC) at different berths. This provides the benefits of standard, straightforward connection
without the need for adaptation and adjustment at different locations that can satisfy the
requirement to connect for as long as practicable during stays in port.
Ships that do not apply this standard may find it impossible to connect to compliant shore
supplies.
Where deviations from the requirements and recommendations in this standard may be
considered for certain designs, the potential effects on compatibility are highlighted.
Where the requirements and recommendations of this standard are complied with, high-
voltage shore supplies arrangements are likely to be compatible for visiting ships for
connection.
Clauses 1 to 12 are intended for application to all HVSC systems. They intend to address
mainly the safety and effectiveness of HVSC systems with a minimum level of requirements
that would standardise on one solution. This standard includes the requirement to complete a
detailed compatibility assessment for each combination of ship and shore supply prior to a
given ship arriving to connect to a given shore supply for the first time
Annex A includes cabling recommendations that should be used in HVSC systems.

The other annexes in this standard are ship specific annexes that include additional
requirements related to agreed standardisation of solutions to achieve compatibility for
compliant ships at different compliant berths and to address safety issues that are considered
to be particular to that ship type. These annexes use the same numbering as Clauses 1 to 12
with an annex letter prefix. Hence, the numbering is not necessarily continuous. Where no
additional requirements are identified, the clause is not shown.
It should be noted that Annex A is considered informative for the purposes of this document.
This annex contains performance-based requirements for shore connection cable, 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.

UTILITY CONNECTIONS IN PORT –
Part 1: High Voltage Shore Connection (HVSC) Systems –

General requirements
1 Scope
This part of IEC 80005 describes high voltage shore connection (HVSC) systems, on board
the ship and on shore, to supply the ship with electrical power from shore.
This standard is applicable to the design, installation and testing of HVSC systems and
addresses:
• HV shore distribution systems;
• shore-to-ship connection and interface equipment;
• transformers/reactors;
• semiconductor/rotating convertors;
• ship distribution systems; and
• control, monitoring, interlocking and power management systems.
It does not apply to the electrical power supply during docking periods, e.g. dry docking and
other out of service maintenance and repair.
Additional and/or alternative requirements may 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 MW
or more or ships with HV main supply.
Low-voltage shore connection systems are not covered by this standard.

4.2 Distribution system
4.2.1 General
Typical distribution systems used on shore are given in IEC 61936-1. Typical ship distribution
systems are given in IEC 60092-503.

NOTE IEEE Std 45™ provides additional information on typical ship distribution systems.

4.2.2 Equipotential bonding
An equipotential bonding between the ship’s hull and shore earthing electrode shall be

established.
Verification of the equipotential bonding shall be a part of the safety circuit (see 7.2.5). Loss
of equipotential bonding shall result in the shutdown of the HVSC system, and the ship shall
go into ship power restoration mode (see 8.6).
NOTE The terms earth(ing) and ground(ing) are used interchangeably throughout this standard and have the
same meaning (see IEC 60050-195:1998,195-01-08).
4.3 Compatibility assessment before connection
Compatibility assessment shall be performed to verify the possibility to connect the ship to
shore HV supply. Compatibility assessment shall be performed prior to the first arrival at a
terminal.
Assessment of compatibility shall be performed to determine the following:
a) compliance with the requirements of this standard and any deviations from the
recommendations;
b) minimum and maximum prospective short-circuit current (see 4.7 and 4.8);
c) nominal ratings of the shore supply, ship to shore connection and ship connection (see
5.1);
d) any de-rating for cable coiling or other factors (see 7.2.1);
e) acceptable voltage variations at ship switchboards between no-load and nominal
rating (see 5.2);
f) steady state and transient ship load demands when connected to a HV shore supply,
HV shore supply response to step changes in load (see 5.2);
g) system study and calculations (see 4.8);
h) verification of ship equipment impulse withstand voltage;

i) compatibility of shore and ship side control voltages, where applicable;
j) compatibility of communication link;
k) distribution system compatibility assessment (shore power transformer neutral
earthing);
l) functioning of ship earth fault protection, monitoring and alarms when connected to a
HVSC supply (see 8.2.2);
m) sufficient cable length;
n) compatibility of safety circuits, in accordance with 9.1;
o) total harmonic distortion (THD) (see 5.2);
p) consideration of hazardous areas, where applicable (see 4.6.4);
q) when a HV supply system is connected, consideration shall be given to provide means
to reduce current in-rush and/or inhibit the starting of large loads that would result in
failure, overloading or activation of automatic load reduction measures;
r) consideration of electrochemical corrosion due to equipotential bonding;

s) utility interconnection requirements for load transfer parallel connection; and

t) equipotential bond monitoring.

4.4 HVSC system design and operation

4.4.1 System design
The design and construction shall be integrated and coordinated among the parties
responsible for shore and ship HVSC systems.

System integration of shore and ship HVSC systems shall be managed by a single designated
party and shall be performed in accordance with a defined procedure identifying the roles,

responsibilities and requirements of all parties involved.
4.4.2 System operation
During the operation of HVSC systems, PIC(s) shall be identified at the shore facility and on
board the ship for the purposes of communication.
The PIC(s) shall be provided with sufficient information, instructions, tools and other
resources for safety and efficiency of these activities.
4.5 Personnel safety
Construction of the HV equipment and operating safety procedures shall provide for the safety
of personnel during the establishment of the connection of the ship supply, during all normal
operations, in the event of a failure, during disconnection and when not in use.
The use of the term “safe” is not intended to suggest or guarantee that absolute safety can be
achieved in any situation and/or by compliance with the recommended practices set forth
herein. The use of terms such as “safe,” “intrinsically safe,” “electrically safe work practices,”
“safe work condition,” “safe work environment,” “safe design,” “safe distance,” “safe work
method,” “safe work area,” “safe use,” etc. describe practices, conditions, etc. in which safety
risks are minimized but not eliminated absolutely, such that safety is not guaranteed.
4.6 Design requirements
4.6.1 General
Protection and safety systems shall be designed based on the fail safe principle.
Suitable warning notices shall be provided at locations along connection equipment routes

including connection locations.
4.6.2 Protection against moisture and condensation
Effective means shall be provided to prevent accumulation of moisture and condensation,
even if equipment is idle for appreciable periods.
4.6.3 Location and construction
HVSC equipment shall be installed in access controlled spaces.
Equipment shall be suitable for the environment conditions in the space(s) where it is
expected to operate. Ship equipment shall comply with the applicable requirements of
IEC 60092-101 and IEC 60092-503.
