Overview
ISO 22472:2016 - Ships and marine technology - Guidelines for the operation and installation of voyage data recorder (VDR) - provides practical guidance for planning, installing and operationally testing VDR installations in accordance with IMO Resolution MSC.333 (90) and IEC 61996‑1. The standard focuses on interface requirements between the VDR and external sensors, commissioning and performance testing, playback and download considerations for investigation authorities, and guidance for whole or partial replacement of simplified VDRs (S‑VDR) per IMO MSC.163 (78) and IEC 61996‑2.
Key topics and technical requirements
- VDR interfaces and input signals: guidance on required data inputs and formats (IEC 61162 series and other formats), including bridge audio, VHF audio, radar and ECDIS display connections, AIS and bridge alert management.
- Sensor interface details: definitions and expectations for time/date, ship’s position, speed, heading, depth (echo sounder), rudder orders/response, engine/thruster orders, wind, accelerations, hull stresses, door statuses, rolling motion, configuration and electronic logbook data.
- Installation requirements: required equipment list, power supply arrangements (ship emergency and reserve sources), protective capsule and float‑free capsule installation, microphone placement, cable routing and ship‑specific documentation needed for approvals.
- Testing & commissioning: acceptance (commissioning) tests, operational and annual performance tests, and templates for performance test reporting.
- Playback & download: requirements for download/playback equipment and information required by investigation authorities to support casualty investigations.
- Documentation: manufacturer documentation, configuration data and network/image transmission guidance for ECDIS and radar.
Practical applications and who uses it
ISO 22472:2016 is intended for stakeholders involved in the lifecycle of VDR systems:
- Shipowners and operators - for compliant installation, commissioning and maintenance planning.
- Shipyards and naval architects - to ensure correct interfaces, cable routing and placement of protective capsules.
- VDR and sensor manufacturers - to align product interfaces, data formats and documentation with shipboard integration needs.
- Flag state surveyors & classification societies - to assess installations and approve commissioning/performance tests.
- Accident investigators - to understand recorded data formats and playback/download requirements.
Practical benefits include clearer technical agreements between parties, reduced installation disputes, reliable data capture for safety investigations, and smoother regulatory approvals.
