GB/T 23428-2026Ships and marine technology - Heading control systems (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document supersedes GB/T 23428-2009 "Board and Marine Technology Bowing Control Devices" and is consistent with GB/T 23428-2009.

Compared to previous versions, aside from structural adjustments and editorial changes, the main technical changes are as follows.

---Terminology and definitions have been changed (see 3.1, Chapter 3 of the 2009 edition);

---Added abbreviations (see 3.2);

---The International Maritime Organization (IMO) performance requirements stipulated in each clause have been added (see Chapter 4). Furthermore, Chapter 4 has been divided into operational requirements.

The requirements for functions and control performance (see 4.2~4.4) have been revised, and corresponding testing regulations have been added (see Chapters 6~8).

---Added requirements including standard alarm identifiers, BAM requirements, test methods, communication procedures, and other implementation-related requirements (see...).

4.3.4, 7.4, Appendix B);

---Added test procedures and required test results for using IEC 62065:2025 ship motion simulators (see Chapter 5~).

Chapter 8);

---Added requirement for performance testing of the bow control system using an IEC 62065 ship model and wave disturbances (see Appendix A);

---The interface requirements related to IEC 61162 have been changed and detailed (see Appendix C, 4.3.15.3 of the 2009 edition).

This document is equivalent to ISO 11674:2019 "Boards and marine technology - Bow control apparatus".

1 Scope

This document specifies the minimum operational requirements, functional requirements, control performance requirements, and test methods for bow control devices installed on ships.

And the corresponding necessary test results.

This document applies to heading control devices that conform to the performance standards adopted in Annex 3 of International Maritime Organization (IMO) Resolution MSC.64(67).

This document describes a ship motion simulator used for performance testing, based on a ship model employing a propeller propulsion and conventional rudder combination system. Its speed...

The range can reach up to 30 kN. The test results are also applicable to ships operating with multiple parallel rudders.
