Schiffe und Meerestechnik - Selbststeueranlagen (ISO 11674:2000)
Diese Internationale Norm legt den Aufbau, die Leistung, die Kontrolle und die Prüfung von Selbststeueranlagen fest, die an Bord von Schiffen eingebaut werden sollen.
Sie gilt für Selbststeueranlagen, die ein Schiff in die Lage versetzen, innerhalb der Grenzen, die durch die Manövrierfähigkeit des Schiffes gesetzt sind - zusammen mit ihren zugehörigen Kursinformationsquellen - einen vorher eingestellten Kurs zu halten, wobei die Ruderanlage des Schiffes möglichst we-nig betätigt wird.
Die Selbststeueranlage kann mit einem Bahnführungssystem zusammenarbeiten, das die Schiffsvorausrichtung entsprechend der Drift korrigiert.
Für die Durchführung von Kursänderungen des Schiffes kann eine Drehgeschwindigkeits-regelung oder eine Regelung des Drehradius vorgesehen werden.
ANMERKUNG Alle Textteile in dieser Internationalen Norm, die mit Texten in IMO-Resolutionen identisch sind [Resolution A.342(IX), mit Änderungen nach Resolution MSC.64(67), Anhang 3, und Resolution A.694(17)], sind kursiv gedruckt.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11674 was prepared jointly by Technical Committee ISO/TC 8, Ships and marine
technology, Subcommittee SC 6, Navigation and IEC/TC 80, Maritime navigation and radiocommunication
equipment and systems.
This first edition cancels and replaces ISO/TR 11674:1996.

INTERNATIONAL STANDARD ISO 11674:2000(E)
Ships and marine technology — Heading control systems
1 Scope
This International Standard specifies the structure, performance, inspection and testing of heading control systems
to be installed on board ships.
It applies to the heading control systems which enable a ship to keep a preset heading with minimum operation of
the ship's steering gear, within limits related to the ship's manoeuvrability in conjunction with their sources of
heading information.
The heading control system may work together with a track control system adjusting its heading for drift.
A turn rate control or a turning-radius control for performing turns may be provided.
NOTE All the text in this International Standard identical to that in IMO Resolutions [Resolution A.342(IX) as amended by
resolution MSC.64(67), annex 3 and Resolution A.694(17)] are printed in italics.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

4 Performance
4.1 General
4.1.1 The heading control system shall be capable of adapting manually or automatically to different steering
characteristics of the ship under various speed, weather and loading conditions, and provide reliable operation
under prevailing environment and normal operational conditions.
4.1.2 Heading control systems shall conform to the environmental requirements of IEC 60945 for equipment
categories protected from the weather.
4.2 Constituents
A heading control system shall be composed, as a minimum, of the following components (see Figure 1):
a) heading-signal processor (including an indicator of the heading);
b) operational control for preset heading;
c) operational controls for adjustments;
d) automatic steering device;
e) change-over device (with steering-mode indicator) which is not required to be an integrated part of the heading
control system;
f) alarm signalling facilities compliant with the requirements of this International Standard;
g) indicators for steering mode and heading source in use.
4.3 Functional requirements
4.3.1 Change-over from automatic to manual steering and vice versa
4.3.1.1 Change-over from automatic to manual steering and vice versa shall be possible at any position of the
rudder and shall be activated by one manual control within 3 seconds.
4.3.1.2 Change-over from automatic to manual steering shall be possible under any conditions including any
failure in the heading control system.
4.3.1.3 When changing-over from manual to automatic steering, if there is no new safe input of command, the
heading control system shall take over the actual heading of this time as the preset heading.
4.3.1.4 There shall be a single change-over control which shall be located in such a position that it is easily
accessible to the officer of the watch.
