IEC 62065:2025 PDF

Overview

IEC 62065:2025 - third edition - defines minimum operational and performance requirements, test methods, and required test results for maritime track control systems. It implements the IMO performance standards in MSC.74(69) Annex 2 and references IMO resolution A.694(17) (linked to IEC 60945) and IMO MSC.302(87) on bridge alert management (BAM). This technical revision reorganizes annexes, tightens Clause 5 requirements, updates the structure of Clause 6, and modernizes alert management to align with BAM and IEC 62923‑1/2.

Key topics and requirements

• Operational requirements: functionality, accuracy and performance documentation, mode behaviour, along-track speed handling and start/stop conditions.
• Test methods and required test results: standardized execution of operational tests, test setups including ship motion simulators, scenario definitions, and documented pass/fail criteria.
• Alert management: harmonized with MSC.302(87) and IEC 62923‑1/2 to reduce duplicate alerts and improve clarity (see normative Annex F classification).
• Ergonomics and presentation: operator controls, human-machine interface requirements, and information presentation for safe bridge operation.
• Interfacing and sensors: requirements for position, heading and speed inputs, use of IEC 61162 interfaces (Annex K), and fallback strategies for sensor failure.
• Fallback and failure modes: procedures for position/heading failures, backup navigator call, and change‑over between primary and backup controllers.
• Supporting annexes: ship model specification (Annex I), sensor error/noise models (Annex H), scenario plots (Annex G), along-track speed control (Annex B), and guidance for dual-controller systems (Annex C).

Practical applications and users

IEC 62065:2025 is essential for:

• Manufacturers and system integrators designing or certifying track control systems and bridge automation.
• Shipyards and vessel operators implementing automated track-following functionality and conducting sea trials.
• Testing laboratories and classification societies performing conformity assessment and type approval per IMO performance standards.
• Flag states and regulatory bodies assessing compliance with navigational safety requirements.

Implementing IEC 62065 helps ensure reliable track control, consistent test procedures, robust alert handling, and interoperability with bridge electronics - improving navigational safety and regulatory compliance.
