Part 3: Low Voltage Shore Connection (LVSC) Systems –
General requirements

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. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
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.
2) The formal decisions or agreements 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.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC 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
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is 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 or ISO or its directors, employees, servants or agents including individual experts
and members of its technical committees and IEC National Committees 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 Publication or any other IEC
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 some of the elements of this IEC/ISO Publication may be the subject of
patent rights. IEC or ISO shall not be held responsible for identifying any or all such patent rights.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
This Publicly Available Specification (PAS) IEC/ISO 80005-3 has been prepared by IEC
technical committee 18: Electrical installations of ships and of mobile and fixed offshore units,
in cooperation with IEC subcommittee 23H: Plugs, socket-outlets and couplers for industrial
and similar applications, and for electric vehicles, of IEC technical committee 23: Electrical
accessories and IEC technical committee 20:Electric cables, ISO technical committee 8:
Ships and marine technology, subcommittee 3: Piping and machinery, and IEEE IAS
Petroleum and Chemical Industry Committee (PCIC) of the Industry Applications Society of
the IEEE.

This PAS will eventually be replaced with an IEC/IEEE prefix and IEC/ISO/IEEE triple logo
standard.

The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
18/1377/PAS 18/1390/RVD

Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
A list of all the parts in the IEC 80005 series, published under the general title Utility
Connections In Port, can be found on the IEC website.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single period up to a maximum of
3 years, at the end of which it shall be published as another type of normative document, or
shall be withdrawn.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
This Publicly Available Specification (PAS) was developed jointly by IEC technical
committee 18: Electrical installations of ships and of mobile and fixed offshore units in
cooperation with IEC subcommittee 23H: Plugs, socket-outlets and couplers for industrial and
similar applications, and for electric vehicles, of IEC technical committee 23: Electrical
accessories and IEC technical committee 20:Electric cables, 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 intention of this PAS is to define requirements that support, with the application of
suitable operating practices, efficiency and safety of connections by compliant ships to
compliant low-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
PAS is intended to allow different ships to connect to low-voltage shore connection (LVSC)
systems 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 PAS may find it impossible to connect to compliant shore
supplies.
Where deviations from the requirements and recommendations in this PAS may be
considered for certain designs, the potential effects on compatibility are highlighted.
Where the requirements and recommendations of this PAS are complied with, low-voltage
shore supplies arrangements are likely to be compatible for visiting ships for connection.
Clauses 1 to 12 are intended for application to all LVSC systems. They are intended to
address mainly the safety and effectiveness of LVSC systems with a minimum level of
requirements that would standardise on one solution. This PAS 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.
The other annexes in this PAS are ship-specific annexes which 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.
