ISO/TC 8/SC 6/WG 1 - Gyro compasses

This document specifies the minimum operational, functional and performance requirements, as well as methods of testing and the corresponding required test results, for heading control systems installed on board ships conforming to performance standards adopted by IMO Resolution MSC.64(67), Annex 3. In addition, it takes into account parts of IMO resolution A.694(17) to which IEC 60945 is associated. Also it takes into account IMO resolution MSC.302(87) on bridge alert management (BAM). In this document, the ship models of simulators used for performance testing are based on those from ships with a combined system of propeller propulsion and conventional rudder, with a speed range of up to 30 knots. The test results are considered also to be valid for ships with multiple parallel operated rudders. NOTE The text in this document that is identical to that in IMO Resolution A.342(IX), as amended by IMO Resolution MSC.64(67) Annex 3, and IMO Resolution A.694(17), is printed in italics.

ISO 16329:2003 specifies the structure, performance, inspection and testing of heading control systems to be installed on board crafts operating under the following conditions: speed exceeding 30 kn and up to 70 kn; maximum rate of turn 20°/s; the normal range of operation between 70°N and 70°S should, as required by chapter 13 of the HSC Code, comply with the minimum performance requirements specified in these standards. ISO 16329:2003 applies to the heading control systems which enable a craft to keep a preset heading with minimum operation of the craft's steering gear, within limits related to the craft's manoeuvrability in conjunction with their sources of heading information.

ISO 11674:2006 specifies the structure, performance, inspection and testing of heading control systems to be installed on board ships.
