摘要

Martek Marine has launched a bridge navigational watch alarm system (BNWAS) for smaller bridges. From July 2013 existing cargo vessels of 500-3,000gt must comply with the next stage of BNWAS implementation. The Navgard Mini, which has approval from Lloyd's Register, has IMO-compliant alarms and reset switches in a single enclosure, making it very simple to retrofit on the smaller bridges of tugs, OSVs and lower-capacity passenger vessels. The system requires a power supply to deliver full compliance with SOLAS regulations. Existing systems require a button to be pushed to confirm the crew's presence on the bridge. If they don't, an alarm is sounded at regular intervals, making it highly distracting to crew doing other work. The Navgard Mini includes a passive infrared (PIR) motion sensor that detects movement on the bridge. No alarm sounds as long as movement is detected, so crew can work undisturbed. Only when the system detects no movement for a set time, between the IMO's mandated three and 12 minutes, will the alarms sound. As the PIR sensor is part of the panel, no extra installation or additional wiring is needed, reducing the cost, installation time and space needed.
