Voyage Data Recorders

Voyage Data Recorders (VDR)

Like aircraft "black boxes", ship's Voyage Data Recorders (VDRs) enable accident investigators to review procedures and instructions in the moments before an incident and help to identify the cause of any accident. From 1 July 2014 all VDRs installed must comply with the new standards. Kelvin Hughes new X-VDR meets these new standards and offers more flexibility, functionality and features to the operator.

The VDR collects data from the sensors on board the vessel and stores it in an externally mounted Crash Survivable Module (CSM). The CSM is a tamperproof unit designed to withstand the extreme shock, impact, pressure and heat associated with a maritime incident. The CSM may be retrieved from the vessel and the stored data replayed by the authorities for investigative purposes.

Kelvin Hughes Voyage Data Recorders (VDR) and Simplified Voyage Data Recorders (S-VDR) are type approved and exceed the requirements of IMO Performance Standards.

X-VDR

The new standards require VDRs to have both a fixed and float free capsule, capable of holding 48 hours of voyage data. A long term storage medium is also required to record 30 days of data. The new VDR is able to record ECDIS as well as a second radar.

The Kelvin Hughes system is compliant with MSC.333(90) and IEC61996-1 Ed 2.0 and collects data from the sensors on board the vessel and stores it on an externally mounted CSM (Crash Survivable Module). The CSM is tamperproof and designed to withstand extreme shock, impact, pressure and heat.

The following vessels are required to carry a VDR and are subject to an annual survey:

  • All Passenger ships and ro-ro passenger ships
  • Ships, other than passenger ships, of 3,000 GT and upwards constructed on or after 1 July 2002

S-VDR

Simplified Voyage Data Recorder (S-VDR), as defined by the requirements of IMO Performance Standard MSC.163(78), is a lower cost simplified version VDR for small ships with only basic ship’s data recorded.

The following vessels are required to carry an S-VDR and are subject to an annual survey:

  • Ships over 3,000 GT constructed before 1 July 2002
  Specifications subject to change without notice.
Features
Control Control panel is a high resolution 8.4" console mount touch screen display.
System Monitor Continuous and manual health checking of the system displayed using a traffic light system for simple fault diagnosis.
Simple Playback

High speed downloads from the bridge via USB 3.0 of any data and/or period.

Playback on a PC or laptop on board using the newly developed software that enables full voyage analysis and data replay functions.

Easy Installation Cable entry to the Main Electronic Unit (MEU) and cable terminations are quick and simple via an innovative cable gland design, ensuring no specialised tools are required. Specialised cable entries to install VGA, video, power and capsule cables directly into the MEU, enable easy customisation to the vessel's needs.
Compliant Float free, fixed capsules and long term media storage are fully approved, meeting the minimum recording requirements in accordance with MSC.33(90) and IEC.61996-1 ED 2.0).
Upgradeable Quick and simple installation with reduced costs is achieved by a single cable between the MEU and interfaces that contain both data and power, interfaces can also be daisy chained. This expansion capability helps future proof the system should additional connections to the VDR be required for the future IMO requirements.
