Netwave NW-4000 Voyage Data Recorder (VDR / S-VDR) | Marine Black Box System | Fixed Hardened Storage Capsule NW-4800 | Spare Parts, Repair & Worldwide Supply | SM MARINE SERVICE™
The Netwave NW-4000 Voyage Data Recorder (VDR / S-VDR) is a professional IMO-compliant marine Black Box system developed by Netwave Systems B.V., Netherlands. It continuously records vital navigation and operational data from onboard equipment, allowing investigators and ship operators to reconstruct events before, during, and after an incident.
Similar to an aircraft flight recorder, the NW-4000 automatically stores information from multiple bridge systems, including GPS, AIS, Radar, ECDIS, Gyro Compass, Echo Sounder, Speed Log, Bridge Audio, VHF communications, engine commands, alarms, and other navigational signals.
The system is designed to withstand harsh marine environments while ensuring reliable data preservation through its NW-4800 Fixed Hardened Storage Capsule, which protects recorded information against fire, impact, vibration, and prolonged immersion after an accident.
SM MARINE SERVICE™ supplies new, used, and professionally reconditioned Netwave NW-4000 VDR/S-VDR systems, including Data Acquisition Units (DAU), Fixed Hardened Storage Capsules (NW-4800), Remote Control Panels, Interface Modules, Power Supply Units, spare parts, repair services, and worldwide technical support.
