IEC 62065:2014 PDF

Overview

IEC 62065:2014 (Edition 2.0) is the international performance standard for maritime track control systems - systems that automatically maintain a ship’s route or track. It specifies the minimum operational and performance requirements, the methods of testing, and the required test results adopted by the IMO (see MSC.74(69) Annex 2). This second edition (2014) replaces the 2002 edition and introduces significant technical revisions including alignment of alarms with Bridge Alert Management (BAM), revised Category B system requirements, more Newtonian-like ship models with tidal currents, and a new Annex K covering interface requirements.

Key Topics and Technical Requirements

• Operational requirements: functionality, accuracy, performance constraints, alerts and warnings (now aligned with BAM).
• Performance testing methods: defined test scenarios, ship motion simulator inputs/outputs, environmental tests, and acceptance criteria.
• Ship modelling: Annex I provides standardized ship models and parameters adjusted for realistic (Newtonian-like) behaviour and tidal current modelling.
• Interface and data protocols: Annex K (normative) defines IEC 61162 logical interfaces and sentence sets for integration with bridge systems and sensors.
• Ergonomics and human factors: operational controls, presentation of information, and alert management to support safe bridge operations.
• Fallback and redundancy: requirements for fail-over modes (position, heading, speed sensor failures) and manual changeover procedures.
• Sensor error and noise models: guidance in Annex H to simulate realistic sensor behaviours during testing.
• Documentation and declarations: required technical documentation, test reports, and performance declarations for compliance.

Practical Applications and Who Uses This Standard

IEC 62065 is used for:

• Manufacturers of track control/autopilot systems and integrated navigation systems to design and validate products to IMO-adopted performance standards.
• Test laboratories and certification bodies performing type-approval, factory acceptance tests, and independent verification of performance.
• Shipyards and integrators implementing track control into bridge systems and ensuring proper interfacing (IEC 61162) with GPS, heading and speed sensors.
• Class societies, flag administrations and regulators assessing compliance with IMO resolutions (MSC.74(69), MSC.302(87)) and approving equipment for service.
• Ship operators and system engineers evaluating system behaviour, fallback strategies, and human-machine interfaces to support operational safety.

Related Standards (if applicable)

• IEC 60945 - General maritime navigation equipment requirements (where differences exist, IEC 62065 takes precedence).
• IEC 61162 - Digital interfaces for navigational equipment (referenced in Annex K).
• IMO resolutions MSC.74(69) (Performance Standards for Track Control Systems), MSC.302(87) (Bridge Alert Management), and A.694(17).
