Data collected or extracted from all integrated sources, as mentioned above, is stored in the storage capsule and contains information for the previous 12 hours (or 48 hours) and is continuously updated during the journey. In May 2012, the Maritime Safety Committee of the International Maritime Organization (IMO) adopted a revised Recommendation on Performance Standards for voyage data recorders (VDR), which is expected to enter into force on 1 July 2014. The X Series has a compact cable gland for this mountain of new data that needs to be recorded, allowing many cables to operate in a small space. The system uses PC-based software to enable the acquisition of audio, video and electronic data in a single device. Although the main objective of the VDR is retrospective accident investigation, the recorded data can also be used for preventive maintenance, performance effectiveness monitoring, weather damage analysis, accident prevention and training to improve safety and reduce operating costs. [1] “Have we really brought this to the best possible level, what is the best thing we can do? Because what happens now is that in many, many cases, the travel data recorder is only used after an accident,” he said. It`s like saying, well, the patient died, let`s see why. But what he doesn`t do is say, well, we have a new patient. Let`s see if we can heal it before it dies. The next step will be to investigate and determine how the data from the Voyage Data Recorder can be used proactively to prevent accidents, rather than simply investigating the reasons for an accident.
Passenger ships and ships, other than passenger ships, of 3000 gross tonnage or more constructed on or after 1 July 2002 shall be equipped with voyage data recorders (VDRs) to facilitate accident investigation in accordance with regulations adopted in 2000 and which entered into force on 1 July 2002. As mentioned earlier, a VDR, or voyage data recorder, is a tool securely installed on a ship to continuously record important information related to the operation of a ship. It includes a voice recording system for a period of at least 12 hours (for VDRs installed after July 2014, the integrated details recording period is 48 hours in accordance with MSC Resolution 333.90). This record is restored and used to investigate accidents in compressed and digitized form. The S-VDR is not required to store detailed data like a standard VDR, but should store information about the position, movement, physical state, command and control of a ship in the period before and after an incident in a secure and recoverable form. The VDR should maintain continuous records of pre-selected data elements relating to the condition and exit of maritime equipment and to ship command and control. In order to allow for a subsequent analysis of incident-related factors, the recording method should ensure that the different data elements can be correlated in date and time during playback on appropriate devices. The aircraft`s black box contains voice and flight data (called cockpit voice recorders (CVRs) and flight data recorders (FDRs)).
So, obios, are the same as on the ship. IMO now requires the storage of more than one radar display, electronic charts and display information, inclinometric data and automatic identification system data. “In many cases, it is clear that 12 hours is not enough, because when an accident occurs, the VDR continues,” he said. “If you have an accident today and the ship doesn`t sink, the VDR will still work, and if you don`t stop it and. Remove the data before 12 hours after the accident, the data is no longer there. Therefore, they decided to extend this time limit to 48 hours to ensure that the data is still available. “It`s inevitable that you tend to hit the storage limit, so often if there`s a fairly small incident when the ship is on a long voyage, the current requirements may not be enough to cover the time from which you can download the data. The longer storage and the increase in storage space has to do with the volume of data and serenity, I think, from the IMO`s point of view, having increased the storage time where all the data is captured and remains available,” he said. Starting in July, the organization revised its rules for travel data recorders (VDRs) — devices that help retrieve information after a disaster, similar to the function a black box performs after a plane crash. Before 2002, there were no standards for such devices, but now IMO has doubled its initial requirement this year that all passenger ships of 3,000 gross tonnage or more have VDRs, and now they must record more information for a longer period than ever before.
