Bridge navigation watch and alarm system

A bridge navigation watch and alarm system (BNWAS) launched by Martek Marine with a full suite of type approvals from major classification societies enables shipowners to fit the IMO-mandated equipment without delay, it was reported by Martek at the end of July.

The Navgard system offers a relatively low cost and effective means of avoiding operational navigational accidents, it is claimed, and can also double as a bridge security system in port.
