Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,
as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www . i so .org/ iso/ foreword .html.
The committee responsible for this document is ISO/TC 8, Ships and marine technology, Subcommittee
SC 6, Navigation and ship operations.
This second edition cancels and replaces the first edition (ISO 13643-1:2013), of which it constitutes a
minor revision with the following changes:
— Table 8, CC-Code VK symbol “N” to “ν”;
— Table 8, CC-Code RHOWA symbol “P” to “ρ”;
— Table 8, CC-Code OMN symbol “Ω” was changed to “ω”;
— 7.9.2, Equations (1) and (2) in the last term Symbol “φ” was changed to “ϕ”;

INTERNATIONAL STANDARD ISO 13643-1:2017(E)
Ships and marine technology — Manoeuvring of ships —
Part 1:
General concepts, quantities and test conditions
1 Scope
This document applies to manoeuvring tests with surface ships, submarines and models.
This document defines concepts, symbols and test conditions constituting general fundamentals which
are to be applied for the description and determination of certain ship manoeuvring characteristics
together with the respective test-specific physical quantities contained in ISO 13643-2 to ISO 13643-6.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 19019, Sea-going vessels and marine technology — Instructions for planning, carrying out and
reporting sea trials
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at https:// www .iso .org/ obp/
3.1
manoeuvring
all manoeuvres (3.2), manoeuvring tests (3.3) and tests or other methods, such as computations,
simulations, etc. to establish manoeuvring characteristics
Note 1 to entry: Manoeuvring includes measures to maintain cruising conditions under external disturbances.
3.2
manoeuvre
ship operation measures to change course and/or speed, and in case of submarines, depth
Note 1 to entry: Special actions taken, e.g. for casting-off, turning aside or rescuing (person over board), are
included.
3.3
manoeuvring test
test conducted with a full-scale ship, submarine or a model to determine and evaluate the manoeuvring
characteristics under standardized conditions
Note 1 to entry: Manoeuvring tests are often similar to manoeuvres, but organized in such a manner that, as far
as possible, specific manoeuvring characteristics can be measured individually.
3.4
CC-Code
th
computer compatible symbols introduced by the 14 International Towing Tank Conference
3.5
manoeuvring device
rudder, azimuthing thruster, hydroplane, cycloidal propeller or equivalent system used to manoeuvre
(3.2) a vessel
4 Axis systems
4.1 General
Axis systems are three-dimensional, orthogonal, right-handed systems. Earth-fixed and ship-fixed axis
systems are defined in Tables 1 and 2.
4.2 Earth-fixed
