A vdr system is a vessel data recording (VDR) system used to record and store ship-related data. The main goal is to contribute to incident brought on and improve operational protection by noting trends that might cause incidents.
It is additionally a valuable schooling tool with respect to crew, along with an efficient means of creating best practices expected to work onboard what is the purpose of a data audit that are worthy of replication. Additionally, it helps with preventative maintenance, weighty weather destruction analysis and performance efficiency monitoring.
The VDR is a computer system that allows data from a variety of receptors installed on-ship a deliver. The messfühler interface models convert the analog, digital and serial indicators from the product into NMEA strings and then to a final saving medium (FRM).
IMO laws require that a standard VDR stores in least this information: time and period referenced to Synchronised Universal Time (UTC), ship’s placement, speed, going, bridge audio tracks (acquired by one or more microphones placed in order to record interactions and audible alarms), Very good Frequency (VHF) radio landline calls, radar info, depth under keel, primary alarms, rudder order and response, engine order and response, hull openings position, watertight and fire entrances status and, where available, accelerations and hull stresses.
The VDR may store this kind of data for a period of no less than 12 hours just before it is overwritten by the hottest data. It is also in a position to survive hefty weather, collisions and fires, and can be managed from a depth of several metres in normal water.
