What is really the use of VDR system in vessels?

Technically, a VDR or voyage data recorder is an invention crafted for the use of passenger, cargo or ro-ro ships. It is basically a data recording system, which caters diversified information for many intentions, but especially for accident investigation. The many cases of sinking, collision, explosion, and other marine incident have led to the conception of a VDR system.

Essentially, this unusual device must be initiated by all vessels for the compliance of the International Maritime Organization standards. The use of a ship-borne VDR in the maritime field has been justified to advance the operational efficiency and safety levels of every ship.

Despite the fact, the preeminent purpose of a VDR system is for examining marine casualties after the fact, there are more innovative uses of its collected data. The VDR information can be remarkably utilized for central alarm management, performance productivity monitoring, seamanship skill training and more.



The use of Voyage Data Recorders or VDR system for SAFETY

Substantially, the safe affairs of every vessel are indeed very important to ship operators, managers, and even the private sectors. Just as in other fields, the cautious operator aims for a high degree of safety in its navigational transactions. Basically, maneuvering safely and efficiently is a requirement that must be engaged to keep the business. Therefore, measures that embolden and ensure that vessel operations are worked safely must always be the first concern.

Essentially, the VDR and its capability for developing safety in marine transportation are undeniably significant. The wide-ranging record of ship navigation machinery, bridge command, propulsion system, and alarm status administers an extensive analysis database. The information collected could be employed to aid inspectors in pinpointing causes of any marine incident. More vital, it can also be taken advantaged to study precursor events and trends that lead to a disaster. Thus, this can assist in defining proper schemes to prevent similar scenarios in the future.

In fact, accident data could be utilized as a training strategy to make operators be receptive of the probable danger. And as well, help in the prevention of mishaps. Moreover, statistics could also be used in the assessment of particular crucial equipment. Needless to say, in order to guarantee proper maintenance and operation. Or, to establish further redundancy for enhancing safety.



The phenomenal use of VDR data for operational EFFICIENCY

In addition, the operational efficiency is another relevant factor in the maritime industry. In the long run, it’s only the efficient and safe operator will withstand in the marine field. Efficiency can be made better only when the management is able to correlate performance to an equipped base line regulation. Watercraft operators currently depend on the crew to create remarks of ship’s position, time, speed, and other pertinent voyage info. Then, document them on a sheet of paper. Or, encode the data into the computer.

Furthermore, unpredictability in weather conditions, the outcome of current, averaging procedure used to identify SHP, speed, etc on once or twice daily basis lessen the general data integrity. Considering that there’s no way to review the efficacy of every input, the information is frequently of limited use in performance monitoring, except for the purpose of record keeping. The constant surveying of engine and navigation VDR data forms an ideal database for conduct evaluation in an automated design.

Passage statements can be produced from past time history documents on any chosen data fields. Assumptions can be made concerning the engine, hull, propeller effectiveness, and even, fuel consumption. Impressively, the outcome can aid the management in developing excellent schedules for dry-docking and selecting fuel types. Even as well, substantiating claims of energy saving tools. In a real-time manner, the VDR can provide crucial engine data. This is actually to warn the operator of occurring anomalous operating conditions before they can effect in engine impairment.



Below are a few examples of the advantages of VDR data in improving the ship’s overall affairs:

  • Hull and propeller roughness checking
  • Engine Overload
  • Evaluating performance
  • Heavy weather damage avoidance
  • Central alarm management
  • Directional stability
  • Incident investigation
  • Bridge team training
